Title: Mk4 2021 Jazz Brake failure
Post by: BigT on January 13, 2024, 12:22:17 PM
Hi guys, I started my car a couple of days ago and the warning system lit up like a Christmas Tree with Brake Failure followed by a string of other warnings. I moved the car a short distance on my driveway and yes, the brakes had indeed failed.

A call to Honda led me to the AA under the Honda Care Program. The AA checked the vehicle and was unable to find a fault. Fortunately I had taken photos of the warnings. Long story short, the car was taken to my Honda dealer by the AA who also arranged a Hire Car with Enterprise for 3 days. That will elapse shortly, hopefully Honda will extend the use of the hire care until my car is fixed. Honda tested the vehicle the following day and found the same issues. Apparently diagnostics have been sent to Honda for their opinion. Two questions, do Honda provide hire cars/loaner whilst work is being carried out until the car is fixed and has anyone else experienced the same brake failure problem on the new Jazz? Many thanks.

UPDATE:

First of all, thanks to all of you who replied. Moments ago I spoke with my Honda Dealer. The failure of the brakes was due to a failed 'Brake Simulator' which was explained to me as being an electronic servo as opposed to a hydraulic one. An order for a spare part has been made, which was originally set to be delivered sometime in MAY. Apparently that has now been brought forward to the 1st March...ish. Meanwhile Honda Care are paying for a rather nice Nissan high spec'd Juke Automatic. Thats been on hire for 5 weeks so far costing Honda Care circa £1,500, with another month to go. All I can say is TG we took out the extended Honda Care + warranty. The bill is going to be at least £3,000 for the Hire Car, plus whatever costs are involved in the repair. I suspect their wouldn't be much change out of 5K. Anyway I will let you know how it goes when we have a solution. Stay safe everybody. Best regards, T

Hiya ! That’s worrying to read of such a failure ! You would hope the default position was that car wouldn’t move or if in motion the handbrake button would stop the car and not allow further movement ?

Well I think if a display lights up as a warning, it should be pretty clear not to drive. If you think about it and link it bringing on the hand brake in motion, that in itself could also be a risk.

If you had brake failure , that is the brake pedal doesn’t operate anything -then the only option is to use the handbrake . This applies all four disc brakes using the electric servo motors -powered by the 12v battery -this means it’s a fail safe system in case of a failure in The HV battery and hybrid system . Once stopped the car cannot be moved without powering up the HV system . I believe ( and expect someone can confirm ) that the Honda hybrid braking technology is as Toyotas . They have a mechanical link in the brake pedal which can operate the powered hydraulic circuit in case if an electronic failure in the braking controls .  The hybrid braking is mostly accommodated using the generator / electric motor via regen braking . Only at low speeds are the disc brakes used and in parking . Also when the vehicle stability dynamic controls require individual / multiple wheel braking will the discs brakes be activated .I’m including emergency braking as vehicle stability as this is effectively is anti lock braking element

I think I have confusion in your original post. I read it that the hand brake would automatically stop the vehicle which is how I read it, rather than being able to stop the car by activating the hand brake, which I agree with,  and is how you would normally first react with a manual handbrake in any event.

So the normal route of brake pedal, hydraulics, disc to pad didn't work ?

Normally you do have brakes but without servo assist or whatever

So was it brake failure or electric parking brake failure

My 2020 Jazz also came up with a Christmas tree of dashboard lights in early December - everything you can imagine that's connected with braking problems and an ES steering warning too. The brake pedal felt very soft. Honda assistance came out and the car started - without the light-show, but while he was waiting to check the error codes, the lights re-appeared, so in it went to the dealership. They took a week for Honda to diagnose a "brake pedal feel simulator kit" fault. The Jazz is about 6 months out of warranty but they Honda did agree a contribution and therefore a hire car. The part (£1,760-ish) is out of stock, expected March.  I believe that they know about other customers with the same problem....

I remember when cars had a mechanical connection between the brakes and your foot,  some just had a cable which would break on occasion. Didn't make them anymore reliable but maybe a bit cheaper to repair and lot of repairs and servicing you could do yourself.

Its best not to get paranoid about it.  No car maker is completely immune from things going wrong  . And the fact it takes a while  to diagnose and obtain the parts  is in some ways a positive.  Better that than them knowing instantly and having the part in stock because it regularly fails.   But not much consolation if it happens to you . >:(      Cars are getting increasingly complex but they are better. 

Also when looking at forums  for any make of car you have to allow for the fact people tend to post about any problems  or an aspect they dislike.  "Its  complicated" or   "a bigger car would have suited me better"  etc  . Fewer post  to say  "'Nothing has happened  and I love the car" But  reading between the lines I get the distinct impression most mk4 owners are very satisfied  with it  .

In case you are wondering what the purpose of a "brake feel simulator" is and how it works, I've found this presentation:

(direct download link to pdf) https://opensiuc.lib.siu.edu/cgi/viewcontent.cgi?article=1005&context=auto_pres (https://opensiuc.lib.siu.edu/cgi/viewcontent.cgi?article=1005&context=auto_pres)

It is an older work from 2008 outlining the then popular hybrid braking systems of Honda, Toyota and Ford.
I think that most of it still applies (if not even more complex) to today's vehicules.

Short: There is more to a hybrid braking system than meets the eye!

It’s braking by wire - just like we have accelerator by wire -all electronic control with a fail safe mechanical link . You can’t have the level of hybrid motor and generator tech efficiency without electronic braking . It needs the computer speed and calculation power to be able to blend seamlessly the power delivery or braking needs . The conventional discs brakes are there for vehicle stability dynamics as for the majority of braking force the car is using the driven wheels
Title: Re: Mk4 2021 Jazz Brake failure
Post by: Kenneve on February 11, 2024, 05:13:14 PM
Probably a silly question, but I’ll ask anyway.

Assume travelling at 30+ mph in B or D mode and you realise your brakes have failed.
You instinctively reach for the electric handbrake and switch on.

What happens next?

Does the handbrake come on instantly, with full power, locking the wheels? (ABS?)
Or is there some gizmo in the ECU, that applies them  progressively according to road speed?

I presume the second answer in correct, otherwise we would be in a load of trouble. :o
Title: Re: Mk4 2021 Jazz Brake failure
Post by: ColinB on February 11, 2024, 07:57:26 PM
If the "brake feel simulator" is the gizmo identified on slide 20 of the slideset as "The stroke simulator [which] provides a typical pedal feel to the driver", then I wonder what it's failure actually implies? Does it mean the car has no brakes, or does it mean that it feels to the driver as if it has no brakes because he's lost the normal pedal feedback? Slide 33 does seem to imply the brakes are still functional, but without the feedback or any servo boost. Probably not something to experiment with.
Title: Re: Mk4 2021 Jazz Brake failure
Post by: Lincolnshire Rambler on February 11, 2024, 08:21:31 PM
My understanding is that applying the handbrake should stop the car as in an emergency stop- it shouldn’t lock the wheels as the antilock function should stop that ?
The brake pedal is just a position and speed  of pressing down on it -that’s all the car needs to figure out how much braking force to apply . However for driving that doesn’t give any feed back so that’s done electronically via the mechanical brake simulator- maybe best seen as you feather off the brake to come to a smooth halt !
The failsafe function of the hybrid brakes is to press the pedal as it will still bring the car to a stop once ! It has to have a failsafe  if the computer fails or any part of the electronically controlled item.
I saw a you tube on a Toyota hybrid expert explaining their hybrid braking tech - state of the art like Honda s !

Post by: Lord Voltermore on February 12, 2024, 09:32:47 AM
My, possibly simplistic ,understanding is that in the event of a  sudden major electrical failure of the systems clever tricks the traditional  hydraulic elements in the system will still be able stop the car .But maybe not as efficiently.   . The electric handbrake will probably also still be  working .

If the foot braking fails completely due to  a catastrophic loss of hydraulics    you should still have the electric handbrake  as an independent emergency back up.  No different  to the olden days when conventional hydraulic brakes could also  potentially fail  ,leaving you just the mechanical handbrake.   

Its extremely unlikely that the electric  handbrake and  the main hydraulics would both  fail at the same time.
If they do you have have probably offended the fates    ;D

If you apply the electronic handbrake when moving it stops you immediately with a big jolt. I’ve tried it at 5mph slowing down coming to traffic lights ( with no one behind me!). There is no progression it’s full brake lock so I wouldn’t want to try it at speed you’d feel like you were going to rip the back end off the car! But if that was your only choice?
I was thinking about this recently when watching the Cupra car adverts on TV. In one part the car swings round like an old fashioned hand brake turn. So a bit of CGI I think, it’s just not possible.

My guess is you need to hold it up in normal driving to quickly do an emergency stop ? If you lifted it up and released it it probably wouldn’t do a full on stop as it may register an unintentional operation ? (No doubt kids or teenagers would want to give it a go because they can !)
Title: Re: Mk4 2021 Jazz Brake failure
Post by: Lord Voltermore on February 13, 2024, 09:32:13 AM
I too had missed this bit about holding the switch up continuously applies all 4 brakes  using the electric servo.
 If  footbrake pedal suddenly went to the floor and you had no brakes  this  might give an alternative that will still be working.   If you have the time and presence of mind.   

I had felt the quite significant jolt if I apply the handbrake a fraction before I have come to a complete stop.

In view of this new (to me) info I have just been out and tested for myself  what happens if you apply the handbrake at a higher speed.   Unlike when you are stationary  it only continues to apply  the brakes while you are pulling on the switch.    For a fraction of a second the  braking effect is quite slight  - enough to notice if for instance a curious passenger flicks the switch , but not enough to potentially lose control of the car.   If you continue to keep the switch up  the car progressively brakes harder ,quickly coming to a controlled emergency stop.

I quickly found I could control the amount of braking quite effectively   just by varying how much I was pulling on the switch.  Not something you should do habitually of course as you are not in complete control of the steering etc,  but  I would recommend   trying it out somewhere quiet. 

 Dont let the idea of complex braking systems and electric switch handbrakes put you off buying a Mk4 Jazz.  They are common on  modern cars from all makers.  ;)

Now I’m confused, I was under the impression that the handbrake switch was simply a spring loaded on/off switch, with no means of varying the amount of braking effect.
I have my handbrake set to auto release, when moving off and in normal driving, use it when I’m likely to be stopped for some time, ie traffic lights etc.
So , how do I vary the amount of handbrake effort under those conditions?

We've all heard of rusting brake discs on hybrids.
What I wrote in my post of February 12, 2024, 06:11:43 PM is NOT a joke! By occasionally using the handbrake "trick" you keep your brake discs free from serious rust problems. (Expert by experience ;)).

I didnt mean for normal   use   of the handbrake when you are stopped. For that I have always found my standard 'flick 'the handbrake will stay on and  hold the car however steep the hill.  I dont know if you can apply it  any 'harder'.

But in the unlikely event of having to use the handbrake for an emergency stop  I found that  you need to keep pulling  on the switch.  The rate of braking seems to progressively increase  as you slow down.  I dont know if this is  servo assistance gradually  being   increased , or just because there is progressively less kinetic energy  to be overcome .Or  maybe the electric handbrake  servos are  coming into play  .     If you keep the switch pulled up the car stops quite rapidly.  Possibly more rapidly than you need or is advisable in heavy traffic.      I found that by repeatedly releasing and reapplying the  switch   I had a lot more control over the rate  at  which the car came to a stop.   

I hope this explains it.  It might make more sense if you try it yourself  somewhere quiet.  Until now I have  de rusted my discs  using the footbrake. But this may be a better way.

Using the handbrake is certainly the better way to derust the discs. With the foot brake you have to brake quite hard to really activate the rear brakes. Here https://clubjazz.org/forum/index.php?action=dlattach;topic=16448.0;attach=10709 you can read that all four brakes are applied with the handbrake.
And as I said: by using the handbrake like this every now and then I keep my discs shiny (even the rear discs!).(https://www.cheesebuerger.de/images/midi/verschiedene/c010.gif)

Hi all,
As a victim of this failure we are currently without a car until June! Someone sent me the following link on Facebook which indicates that this is a product recall in Japan and so should also be in the UK rather than us being charged £1600 for the replacement part, when it eventually comes. Unfortunately my Japanese is a bit rusty so can't 100% verify!
Has anyone got more up to date information? Our dealership don't seem to be doing a huge amount on our behalf.

I can recall plenty of diy articles etc about  repairing old type servos and braking systems.  Less complex maybe  but  not infallible.

You omitted to add:
"and the cables had to be adjusted regularly.."

My first car was a 1929 Riley 9 Monaco with cable bakes.

I remember when cars had a mechanical connection between the brakes and your foot,  some just had a cable which would break on occasion. Didn't make them anymore reliable but maybe a bit cheaper to repair and lot of repairs and servicing you could do yourself.

Rather than discuss the history of handbrakes, could we perhaps focus on the original post and this very expensive brake failure? BigT and BeckyDuck101 makes two forum members who have this problem. Rather worrying in terms of percentage of forum members.

I don’t have the IT skills to attempt translating the Japanese Honda website, but would appreciate it if somebody could.

Lastly, as my Crosstar is coming up to 3 years old, this brake failure issue has convinced me that purchasing the extended warranty could be a wise move.

Therefore, in the process of use, the resistance part in the sensor will corrode, the output value will be abnormal, the warning light will turn on, the fail safe may work, and the operation power of the brake pedal may increase.
Explanation diagram of improvement points

Contents of improvement measures   
Replace the brake operating simulator with a countermeasure product.
However, since it takes time to supply improvement measures, we will add a self-diagnosis software that displays the guidance to that effect on the multi-information display when there is a need for inspection for customers who wish.
In addition, as soon as the parts are ready, we will guide you to replace the parts again.
Measures to make automobile users and automobile specific maintenance companies aware of it   
・User: Notify by direct mail, etc.
・Automobile specific maintenance companies, etc.: It will be published in the bulletin published by the Nichiseiren.

@FMIB: Thank you for the explanation and the concise listing of vehicules affected!

I'm very comforted by the fact that Honda have already addressed this issue!

Nevertheless I can feel with the owners of affected cars - thanks to FMIB's information they should have it easier talking about this issue with their respective dealers.

I think my Jazz has also developed the same fault.  All sorts of warning lights and virtually no brakes when pulling away. Brake pedal feels incredibly hard to achieve any stopping at all. Happened three times now.  Was hoping might just be 12V battery low, but have charged it and fault still appears.
Out of warranty in September 2023, so could be very expensive.  Scandalous on a car that's only done 13K miles

Honda seem to be heading for potentially serious warranty financial problems

Of late I've been reading about the 11G Civic 'Sticky Steering' that is affecting an increasing number of cars in the UK, plus the ever increasing number of 10G 1 litre destroyed engines due to the wet timing belt either prematurely snapping or fragments breaking off and causing a turbo blockage

Hi BigT,
Interested to know how you are progressing re brake simulator? When ours went haywire we were originally told end of March for the part to be shipped from Japan but that was then counter offered with June. That will make it 5 months without a car that was only 3.5 years old!
It would be great to know how others are getting on!
Best, Becky

I am surprised there isn’t more interest on the Forum about this subject. From what I understand it seems to be cars over 3 years old that are experiencing the fault and some low mileage ones too so looks like it is either age related (slow deterioration of the affected part) or batch related which is what the translation of the Japanese website suggests.

My Crosstar will be 3 years old in June and I believe it was manufactured in January 2021.
Do I have a suspect brake simulator in my car? Will it fail at some point in the future and if so will the car be off the road for 3 to 5 months waiting for replacement parts?

This is my first Honda and I know there are a lot of loyal Honda folk here. I like my car but this major brake failure and the inability of Honda to fix it in under 3 months makes me wonder about the brand and whether going forward (even with the purchase of an extended warranty) I want to take that risk. As the car approaches 3 years old in June, maybe I should think of changing.

I have wondered about this too. My first Honda, after years of Renaults with no problems. The Honda was bought as a 'last' car, something I believed would give me reliability, trouble free motoring and a car I could keep long-term. So far I have needed a new washer nozzle and a new windscreen, albeit under warranty.. but in a car that is only just 18 months old and 17k on the clock. Now I am hearing about failing brakes and engines rattling themselves about like a bag of spanners in a washing machine! I have 4 more services, and 3 and a bit left on the 5 year plan. I really hope that after this period the car is still going strong, but I am nervous.

Post by: Lincolnshire Rambler on March 20, 2024, 08:47:02 PM
Yes it is disconcerting to read of the brake simulation failure . Having had a rodent damaged wiring loom my jazz will be off the road while a new loom arrives from Japan in may .  That’s going to be 3 months of zero use so how will the HV battery cope with that ? Having looked at wiring looms on several new cars at work including a nissan x trail electric hybrid I now consider the loom protection on Honda to be inadequate. A lot of the Honda loom is just wrapped in vinyl tape -(not referring to the orange HV ). All other manufacturers are using that tape but surrounding by lots of convuluted tubing giving an extra layer of protection . So I will be heading to Toyota as their loom protection is a step better  IMHO -which is disappointing as the jazz is a great design !  Once my 5 services has passed and my 3 year warranty ends then I’m getting more convinced to swap to Toyota hybrids …

Evening.

I joined this Forum today in the hope of finding out more about what has been described on here as the dashboard lighting up like Christmas and the brakes failing. This has happened to me (60yo F and not a Motorhead).

My Jazz is a 2020 Crosstar - 3 years & 8 months old with less than 7K mileage. I bought the car in February 2022 with less than 1K mileage.

I had a recovery truck take the Jazz to my Honda Dealer today and received a phone call this afternoon to say it was “brake simulator failure” and that repair would be £1797.34 if they could get the part. He anticipated mid April as there were none in the UK or Europe. After reading previous posts, I won’t hold my breath on this delivery date.

The Honda Technician basically said I was out of warranty (obviously the first owner didn’t take out the extended warranty and I was never offered it). So now, like others on here, I don’t have a car, haven’t been offered a courtesy car and have a hefty bill. Any suggestions? I assume they won’t order the part until I pay up?

This problem seems to be far more common that the Dealership realises and isn’t just the Jazz.

Is this a safety issue? Should I just take the hit or argue that a less than 4 year old car with less than 7K on the clock really shouldn’t have a failure such as this?

Firstly, very sorry to hear about your car. Not at all what one expects from a trusted manufacturer and in particular for the Jazz which has a reputation for reliability going back years. As you are a new member of the forum, I wonder what the real percentage failure rate of these cars is in the U.K.  And with your low mileage it is clearly age related rather than use, I.e. mileage. How many others are out there who don’t bother to check the internet or car forums are having brake simulator failure ?

In terms of your particular situation and lack of a warranty, I would suggest pursuance of a goodwill contribution from Honda. Others on this forum who have owned Hondas over many years might be able to offer advice on how to proceed.

I am no legal expert but I'm pretty sure there is a principle that regardless of warranty or guarantee etc, a product such as a car can be expected to operate as intended, safely, or generally be fit for purpose for a "reasonable time".
A major safety system failure such as the brake controller I suspect would fall into this area if it failed in a significantly shorter time scale than should reasonably be expected, and 3 or 4 years would seem well below what any reasonable consumer might expect. OK if it failed after 20yrs then its a different issue. If a domestic kettle failed after 3 yrs it might be just one of those things, but 3 or 4 yrs is not in my opinion a reasonable service life for the principal brake operating component of a vehicle without which the it is unserviceable and potentially extremely expensive to repair.

If a major car manufacturer didn't play the game sensibly on such an issue issue I would suspect a class action might be on the cards providing a suitable legal expert considered it a viable course of action, but I am just guessing and in no way accuse anyone of anything.

Since this is a scary (and expensive) problem, I would advise many of us to make some noise to dealerships and perhaps Honda Japan via email, to get some more information and not allow something like this to get swept under the rug.

Daffodil, I would be making noise with Honda direct. I would cause as much stink about this issue as you can. To be fobbed off with a repair bill for what is really a very worrying safety flaw in a marquee as reliable reputation wise as Honda, is frankly appalling.

I joined this Forum today in the hope of finding out more about what has been described on here as the dashboard lighting up like Christmas and the brakes failing. This has happened to me (60yo F and not a Motorhead).

I had a recovery truck take the Jazz to my Honda Dealer today and received a phone call this afternoon to say it was “brake simulator failure” and that repair would be £1797.34 if they could get the part. He anticipated mid April as there were none in the UK or Europe. After reading previous posts, I won’t hold my breath on this delivery date.
Welcome to the forum!

(and sorry to hear about your car)

Have you apprised your Honda dealership of the information provided by FMIB in this thread? (https://clubjazz.org/forum/index.php?topic=16448.msg141516#msg141516)?

What he posted seems to be proof that Honda is aware that something was amiss with the brake simulator for the cars manufactured in the periods mentioned:

July 2, 2018 - March 1, 2020
(Total 525,568 units)
※This case was reported for improvement measures at the notification number "661" dated March 31, 2020, but since a new cause has been found, the improvement content will be changed and notified again.
※Part of the scope includes vehicles that are not subject to renovation.


Half a million cars with this kind of fault is nothing to sneeze at!

Please show this information to your dealer and/or your lawyer (it might help your position).

Good luck!

I agree.   
I have had no problems with my car so far  and  maybe i am being a bit sanguine as  a result.

Honda have a big presence in the USA   where consumers are notoriously inclined to  litigation for  compensation. Honda may have decided they dare not risk Billions of Dollars in claims  by any suggestion they may be attempting to suppress information or minimalize  the seriousness of something they were aware of.  Revealing the number of vehicles affected, or potentially affected,  is no doubt very damaging to their reputation.

But should a company that 'comes clean' be given some credit?    I do wonder how many other manufacturers are aware of similar ,or worse , problems in their vehicles  but have chosen to keep it secret as much as possible and been quite successful in doing so. Deceiving European consumers and recall safety regulators may be easier.    Even the most basic of new cars now come with complex  braking systems  ,electronic driver aids etc.  And sometimes the component parts are made by independent OE equipment manufacturers who also supply  components to other car manufacturers. 

There have been many recent revelations of quite respected manufacturers having cheated on emissions and crash testing etc,  and its always been the case that some businesses use very dubious  morals when it comes to protecting their profits and reputations, with their  employees being complicit  in this to protect their job.

Honda, Toyota and one or two Korean brands tend to dominate the top places in reliability surveys. I'm not sure that changing to a lower placed make  would necessarily improve its reliability prospects.  Especially if I have not read  as many forum posts etc from owners of that car which can tend to highlight any problems but not necessarily the likelihood of such problems. 

But i accept i may take a complete different view if faced with major expense and delay. Thats something Honda should do something about. There is no excuse for parts delays  if at the same time they are  using the same part  to build a new car. Airfreight that part  so  a recently sold car can be promptly repaired.    But Honda are not alone in this.    A bit of delay and confusion in diagnosing a fault is a bit more acceptable.  That suggests  the fault is not that common.

I can imagine that Honda engineers are working day and night to solve the problem. However, changing the entire braking unit is a rather crude and expensive option. I think they are trying to find out which part is actually causing the malfunction. That might uncover the extent of problems, but also simpler and cheaper solutions.

I hope, in the very near future, Honda finds a workable solution, maybe even a routine test, to go through all cars while in for regular maintenance and repair or replace when needed.

But in the meantime: Honda, please be transparent, admit the problems and make your customers feel heard and taken seriously.

I wonder how common this fault is? What are the odds of you getting it with your car? Is this a problem with electrified cars in general? (Local story about a Jaguar i pace whose brakes failed and the police had to ram it off the road).

I'm sensing we are a bit short of information here across the whole issue.

I do have a bit of experience about another common fault however and this related to the ABS braking system on the Mk5 VW Golf. This failed so often that support groups were set up and pressure was put on VW to repair on a "good will" basis for cars out of warranty.

Like others I had hoped this would be my last car. I am now thinking I'd like to get rid.

A question for those affected by this issue: did this happen after recently changing the brake fluid?
I ask this because in the service manual, braking fluid change is due every 3 years, and the Jazz EHEV is 3 years old for most people.

I have just discovered this forum since I also appear to have the brake problem with my Jazz eHEV which is 3.5 years old with just under 9K mileage. When I started up yesterday I got the “Christmas tree” lights effect on the display which was flashing between ES and EP with 2 red circles around the letters. When I tried moving the car I noticed the brakes were very spongey and after driving the car a few yards I got a red Stop signal. I put the car back in my parking slot and phoned my local Honda dealer who informed me that the earliest they could take the car in for a diagnostic check would be Wed 3rd April. My 3 year warranty expired in Sep 23 so I guess I am in for a big hit financially. I will post the result of the diagnostic check as soon as I have it.

This is a very concerning thread, since it was started a couple of months ago.

When I bought my EX model, one year and ten months ago, I was fortunate in taking advantage, of the five year guarantee and servicing, if I took out the Honda finance deal for a minimum of six months.

Am I correct in thinking, that this brake simulator, will be covered for the full five years, for those fortunate enough to have had the finance deal package in place?

Still think this is a brilliant car though!

As unfortunate as these instances are, I'm also a member of the Mazda CX-60 forum on Facebook. To say that the CX-60 is an utter ********** show in terms of reliability is an understatement. Early adopters have been saddled with a plethora of problems. There are currently more than 10 TSBs to address serious issues - such as sticky steering, transmission shock (juddering), rear suspension / front suspension problems, camera failures (which result in the vehicle slamming on the brakes for ghost vehicles etc, etc). I'd say that, at a guess, most owners have at least 5 issues, with some experiencing 20+ (to the point that countless owners are trying to reject their vehicles). And this was Mazda's so called attempt at luxury!!

So, in comparison, the Mk4 Jazz is reliable as they come. Yes, the brake failure one is expensive. And I sympathize with owners who have had that issue :( But let's put things into perspective! I think us Honda owners are spoilt sometimes ;-)

I too find it a tad concerning and similarly to you, my car is 1 year 6 months old. However, it was pointed out earlier in the thread that this simulator was a known (by Honda) fault, and was restricted to cars manufactured in a certain timescale during 2020. So hopefully we are ok.

If you check your car's VIN (chassis) number against the list on page 4 of this thread you can be certain one way or the other (unfortunately my Crosstar is on the list)

I don’t follow the logic of this post. Just because there is another model of car with numerous faults does not mean that the problem with the brake failure with the Jazz eHEV models is not serious. It renders the car undriveable and the time off road and cost of repair is unacceptable for a low milesge vehicle that is only a few years old.

Suddenly had virtually the same problem last night (various messages, actual poor braking etc ) as you (Chis 52). After turning off the ignition it became driveable again. Same thing happened today and again after turning off once or twice it was OK. I have contacted my local dealer and dropped the car off as they may have a brief look Thursday but more likely, like you, early next week. Its only 3 years 9 months old with 12000 on the clock. I would like to know how many cars are having this problem. I'm not use to this with Honda having owned a Honda Jazz (Mk 2 and Mk3) since 2009. I dont have an extended warranty but I would hope that Honda will be supportive on this. We will see!

This sounds like a significantly growing problem.  I'd be amazed if a manufacturer could get away with dismissing the issue or making customers pay for it to be fixed,  imagine the negative press it would lead to. Who would want to buy a used example if they could be landed with a disabled car and a £1500 bill shortly after buying a 3yr old car?

It does look as if there are at least 5 or 6 similar problems just on this forum and looking at the CRV forum and Japanese "recalls" list it may well be fairly extensive or possibly so in the future. Once my garage have actually diagnosed the fault, although it certainly looks like it will be the brake simulator from these posts, I will certainly expect a goodwill gesture on a car of this age and mileage and if not I will take it further with Honda and elsewhere if necessary.
Like most Honda owners I have always been impressed with their reliability and advocated them to many friends and so I really do hope they will sort these problems out in the right way for all customers.

Having to wait months for repair due to parts supply is unsatisfactory

... and while your car is standing around waiting, the batteries are probably degrading which may lead to future problems

For those interested or perhaps you have seen it already since you are worried about your brakes and been trawling the web -  there is an interesting recent thread on Honest John  concerning Brake Servo Failures.

https://www.honestjohn.co.uk/forum/post/197644/honda-jazz-hybrid

Looking at the Japanese translation (thank you for doing that FMIB)  like "Lord V"my car might be in the list if you ignore previous letters and numbers, but not sure if that will be the case or relevant here. I have mentioned it to my dealer but they say they can only go on what UK Honda say. The dealer has dealt with several of these faults before and currently has one order for someone coming in mid April. Mine may get diagnosed today if they have time and then they may contact Honda for goodwill. As I said before we will see!

It might be that the 7 digits are referring to the engine number, as the brake servo is bolted onto the engine (on the backside).
My 2022 Jazz has engine number GR3-LEB8-3102084 , condensed to GR3-3102084 there is no match in the list.
I guess the Honda dealer or importer should know what the 7 digits are referring to.

And not having repair kits available for a common fault is disgusting.

It could be the engine number  . My engine number   is  about 95 thousand lower than  the 1200001 number and its not impossible the engine was made before 21 may 2021  ,even if the car itself was assembled later. There was chip shortage at the time.    My car is only about 1 year older than yours yet your engine number is 2 million higher than mine.  I doubt they made 2 million more engines in a year, or had 95,000 in stock when my car was built.

So if its based on engine number my car is in the clear   :P I wonder what changed.    If its Chassis number I am not. :(.   Maybe its better not to know  or worry about it.   This is my first Honda car  so I am not particularly brand loyal. But  I still think its better the devil you know and which has  a good reputation for reliability  than changing to another  brand who might be hiding their  secrets .

The numbers on the Japan list are all Japan market VIN, they do not use a 17 digit VIN, they only have the model code (GR3 etc. and 7 digits. So these numbers have no relevance to European models.

Maybe its because the fault is only now appearing. It seems to be an age related, rather than mileage related issue. Cars reaching the 3.5 year old period, and by all accounts limited to a batch.

My update from the dealer this afternoon.
As expected it is the Brake Simulator. They have contacted Honda who have agreed to contribute just over £400 towards the part which costs £1428.35 (inc Vat) but the final bill would still be at least £1300 with labour. To be fair the Dealer is very supportive and agrees with me that this is far from ideal.
I have phoned Honda UK Customer Service and politely told them the situation  (with many similar faults with other customers and with the Japanese recall ). I have emphasised that such a part which is faulty and could cause an accident with a brake failure is not up to what I had believed Honda standards to be. Indeed it is so dangerous that there needs to be a recall immediately. Furthermore, I and other customers should not have to pay. They are expected to come back to me by the end of next week with an answer from higher up.
My current dealer has checked with one of its other dealers and they have had 6 similar failures on the Honda E and Jazz in the last few weeks.
I feel that other customers should also contact Honda UK by phone or email if they haven't already and be prepared to follow through with various consumer groups. The simulator on these faulty cars is obviously not fit for purpose. This fault may well be putting many customers unknowingly in considerable danger and the right thing to do is for Honda to make it public. Good customer service means putting things right as soon as possible.  Lets hope Honda does something very quickly. My dealer has ordered the part and possible delivery date may be by the 15th April. I will update when I have further information from Honda or my dealer.

This is the beauty of forums like this. It is a perfect example of how sharing information can lead to positive action. I wonder how many Jazz owners with this fault there are that don't belong to this group, who don't know it is a recognised problem and will just accept the car is out of warranty, and pay up without a fuss.

My first motor vehicle at the age of 16 was a Honda C50. This motorcycle, the worlds biggest selling motor vehicle, was the foundation of Hondas reputation.      Here is an extract from the Wikipedia entry-

"The Super Cub sold poorly at first, owing mainly to the recession in Japan, and then three months after the 1958 launch when customer complaints began rolling in about slipping clutches. Honda salesmen and factory workers gave up holidays to repair the affected Super Cubs, visiting each customer in person."

As Cobb2 implies this absolutely should be a recall and I guess the only reason it hasn't been is that it will be ruinously expensive for Honda as it's clearly not just the Jazz that's affected.

I'll be honest and I speak as a Honda loyalist, if I'd known this was an issue I wouldn't have touched the Jazz Mk4 with a 10 foot barge pole. The car is potentially dangerous and you have the knowledge that a massive bill might be winging its way to you at some point.

I want out - I want rid of this car. I'm going to start looking at my options.

I suspect that the real cost of the problem part and the labour to replace it is much less than the cost that people have been quoted. I suspect that Honda are still trying to figure out the extent that the potential problem will become a real problem and also how much boost the production of the appropriate part. Just-in-time manufacturing isn't geared up for a sudden increase in demand for a part. Nonetheless, there appears to be tardiness in Honda Japan telling Honda Europe / UK to be prepared for this. Any problem is potentially reputation damaging, but this can be largely mitigated by promptly applying a fix with minimum inconvenience to owners.

Thank you AshimotoKO for producing even clearer evidence of a manufacturing fault in the brake simulator. This certainly should be very valuable.
Like peteo48 I have been very enthusiastic about Honda over many years and I fully understand your feelings to not carry on with your Jazz. However, I will not jump ship just yet as long as Honda sort this out properly and promptly, which means making it public in the UK and Europe, covering owners costs, and of course replacing the part with a remanufactured one without the fault.
As most of us realise this Mk4 is actually a very good car and it would be a great pity if its and Honda’s reputation is badly damaged by this episode, serious as it is.  Even worse if any accident is caused by it. The only positive thing I can say is the two times the brake problem arose with me it was just when starting the car and effectively a fail safe warning came up and the brakes were spongy and hand brake came on. If this problem occurs when driving it is even more dangerous – I would be interested to know if anybody has had it while actually driving.

So it would seem that the problem is the pressure sensor within the module failing due to contaminant oil (during manufacture) weeping inside and causing corrosion. I bet further down the line that some entrepreneurial company will come up with a repair for these modules that fail. 

I guess this must be the part in question (made by Nissin).

If the part,or one very similar to it, is made by Nissin, an independent OE ( Original equipment ) component manufacturer , and Branded as Nissin in the casting, it would suggest the item is not exclusive to Honda.

Its quite possible other car makers also  design their brake systems to use fundamentally the same  Nissin made component,maybe with slight variations in size etc.    It would be a whole lot easier than designing  and manufacturing your own from scratch.

These other car makers may be facing and dealing with the same  issue.  So maybe look carefully before you leap  to another brand.
If I  was aware of every maintenance  alert issued by Boeing and Airbus I might never fly again  ;D .
 
The Major safety recall in recent years for  faulty  air bags made by the Takata corporation affected many makes of car, not just Japanese ones.  And as a  precaution was extended to countries where no faults had  ever actually been reported.

Interested what the other unit is for sale here ... some kind of pump maybe used in conjuction with the servo unit that is failing. For the price it looks an incredible price for both units if they are indeed as described condition wise. Of course the booster unit may be on the cusp of pressure sensor failure. I am an an electrics engineer and it would seem to me that surely the manufacturer could swap out the black box with the pressure sensor in it .. but hey ho without taking one apart how am I to know. The module would doubtless not be available as a spare part but faced with a deluge of failures/returns maybe this could be addressed with Nissin.

I have LOADS of classic Honda bikes I am restoring and have a mate in Japan (ex pat ,,, Brummie) who buys rare parts for me and ships to UK. Also I recently wanted a genuine rear camera for my Mitsi Mirage (2023 Jazz e:HEV is my wifes car)  It was £120 from a breakers in UK .. Won for £8 in auction on Yahoo Japan (no eBay there)

Anyway searched for the FIT 1.5  e:HEV brake booster and came up with this (it's actually two units in the listing the other is the other braking part). Equivalent to around £130.

Unfortunately we were blocked access to Yahoo Japan in the UK a couple of years ago but i get around it by setting my PC VPN to Tokyo Japan so I did a screenshot of the part.

Sorry for keeping posting links to the used parts and I will stop now. It was mainly to show that used parts are out there if someone is faced with a well out of warranty main dealer repair bill. Hopefully the whole issue will be resolved by Honda in due course, hopefully before my wife's car runs out of warranty (has exacly 2 years left as of today)...  Just wondering if the booster unit that is failing is coded to the individual vehicle though... which would be a bit of a downer for anyone trying to FIT ( :) ) a used part.

If it ever comes to disputes about liability for a car outside warranty we do at least now have supporting evidence of an admission by Honda of a  manufacturing  fault. Which you may not have in a similar dispute with another car brand.

Also if Nissin make similar items  they either made the original ones for Honda , or their product is an  after market alternative.  Either way it offers hope that should repair be necessary once the cars become older  it will be possible to avoid Honda prices.   

If the cost of the part is still high  there is scope for a small business to offer exchange   refurbished ones, with just the sensor /black box electrics replaced and improved  oil sealing.

Thats fine AshimotoKO to make your posts about the part - you have certainly contributed interesting detail about the part in question - excellent research!
 Lord V - maybe reconditioned parts will be available sometime in the future when cars are older which would be good, however, you won't be surprised at this stage with a fairly young low mileage car, I would certainly want a new part and so will others - all provided free. Apparently Honda have been the main shareholder in Nissin, not sure if they still are, but there is an interesting Wikipedia page on them.

In reply to Lord Voltermore concerning Boeing and Airbus with regards to TSB's ( technical service bulletins )and safety recalls etc , you would be quite surprised just how many all the major manufacturers have recalls and modifications etc , it is far better to have a recall than just leave until it becomes a major fault.
This really applies to all cars , cycles, motorcycles etc etc.
I worked for 30 years with Airbus and they were quite quick to solve service problems for in-service aircraft, part of my job was to travel to where the aircraft was to help fix the problems.
I hope Honda doesn't try to hide the brake fault ,it would forever hit their good reliability reputation for the cars and motorcycles, I have owned Honda motorcycles and the Jazz is my second car from Honda, the first being a 1960's S800 sports car !
I won't sell my car just because of this trouble, I'll try to keep it in perspective , just look at the problems with Land Rover for example, they are fitting reconditioned parts due to lack of new spares.

Some good points made above about getting rid of the car because of this issue. I guess I am a bit risk averse and the idea that this fault could come up to bite me really does cause me stress. I've had 6 Hondas in all and it's their reliability that has kept me coming back for more.

Thinking about it a bit more I will probably hold on to the car. I could actually manage without a car if it had to go off the road for a while and, as people have said, the risk of a frying pan/fire scenario is also a factor (I gather the Toyota CHR has had similar issues).

Although I have had 3 warranty repairs in my 72 plate EX, mirror motor, screen-wash nozzle and delaminating windscreen, the brake issue I hope was pre my manufacture. Knowing how many other makes regularly have recalls, faulty parts and software update requirements, I am not going to suddenly decide to jump ship and offload the Jazz. As someone has mentioned previously, the Jazz is a great car and way ahead in my opinion of other hybrids. The brake issue I am sure will become a public topic soon enough, and will be replaced to avoid any negative effects on Honda's reputation.

Hi, new Member here. I joined because on Tuesday my Jazz SR 2020 with 13k miles had the same brake failure when I started it at home. Undriveable, confirmed by the AA's Agent. It is booked in to the local Honda dealer next Thursday. It will need to be recovered and trucked there. Dealer says this is their second Jazz Mk4 brake failure.
Luckily I do have some remaining cover under the 5 Year Care Package warranty. I spoke to Honda Administration. I only have 72 hours car hire paid for by Honda UK. They say because the repair takes only 2.4 hours, they won't extend the car hire. Only if the repair takes over 8 hours do they pay for longer car hire. All still subject to the dealer's workshop report anyway. This is a known common fault so Honda Admin expects it will be covered by the warranty.
I am fuming because I am entitled to claim back all my loss (including any extended car hire and other expenses resulting from this latent defect aka "failure") from honda UK. See the indemnity expressed in warranty clause 13 b) ii. I will not let this go. Legal claim to follow if necessary.
The other issue as mentioned in this thread is lack of an official recall by Honda UK. Ridiculous. How can this common brake failure not be a safety issue?

Sadly, this is the reality of Just-in-Time manufacturing. To reduce their costs, Honda will not have a warehouse full of spare parts, they will have screwed down their suppliers to provide exactly what they need when they need it to match their production schedule. So any unexpected or unusual demands for spares, such as these brake system components or Rambler’s wiring loom, have to be added into that production schedule. And then you have the shipping time. I doubt this is unique to Honda, most if not all manufacturers are like this these days.

From the excellent post on page 4 (by FMIB) it appears this issue only arose with model years 2019/20 ?

Has there been any evidence of failure in models made later, perhaps 22/23?  I read that the issue can arise with real low mileage cars as well.  I have just purchased a nearly new Jazz advance.  Another two years plus warranty, but as I seem to now drive a Lap Top on wheels computer wise, it will be a wise decision to extend the warranty I think !

But if no issues, what changed re the Brake simulation bit ?

I think that is a translation from Japanese and some dates are given in years of the Reiwa (the latest era in the official Japanese calendar,which  began on 1 may 2019.)  This means the latest  date given is february 2022 ,and it is the date the car was built  so some  cars delivered to customers in 2022 are potentially  affected. But less likely to affect 2023 cars , even allowing for a long time on board ship.   But this assumes cars for export were modified at the same time as home market cars, and that the modification has solved the problem.

  Incidentally  another post says the chassis/engine numbers given are a series used on the Japanese home market and cannot be used to cross check chassis numbers for cars delivered to Europe. 

I agree about the increasing  complexity of new cars  (not just Honda) . As the cars become older  I assume  more independent garages will learn how to fix them at a more competitive  price ,  but meanwhile its comforting to have a warranty . i wont be keeping it 14 years like I did the last one   ;D

I find the VIN number list a bit confusing, and a bit of a grey area regarding what is a Japanese car and how does it differ from a EU car in regards to the number. As the problem seems to be age related rather than mileage, and the first generation cars starting to develop the fault after 3 years.. are we now going to see more cars with the fault as the 3 year mark rolls on?... or, do we assume that as the model was recalled in Japan, they have limited the fault to the first gen and subsequent models are OK  ???
I am fortunate that I have the 5 year plan, which comes with the extra 2 year warranty. As this is now a known fault, and could not be classed as normal 'wear and tear', I feel assured that should my September '22 Jazz develop the fault in 3 to 4 years of it's life it will be repaired.

I guess that I will find out on Thursday if the brake simulator / modulator part is in stock, or how long it will take them to get one. The pressure will be on the dealer because they have very limited space to store my Jazz. Meanwhile I need to extend my car hire until at least Friday, maybe longer. Fingers crossed that they can complete the repair on Thursday but I am not going to hold my breath.

If we had some US States consumer law, this debate would be unnecessary.

England does have excellent consumer law, even the possibility of class claims, although the latter is still fairly new and probably under-used.

There is a legal remedy by way of a claim for damages from the supplying car dealer for breach of contract, for those unlucky Jazz owners whose repair costs for this latent defect are not covered by an extended warranty. The Honda warranty is always in addition to statutory consumer protection rights. Never in lieu of such rights. The T&Cs on the dealer's order form cannot exclude or limit these statutory consumer rights. Do not be fobbed off.

If you have legal expenses insurance, check your policy wording to see if it will help fund professional advice and a claim against the supplying dealer in this situation.

BigT (thread starter), PeteS, BeckyDuck101, blythpower, Daffodil, Chris52, Cobb2, and most recently me.

I am waiting for my Jazz to be recovered today by the AA (part of the "discretionary" Honda Care service) and delivered to Bath Honda this afternoon. Update to follow when I have more information.

I suggest that anyone else who experiences this failure and the accompanying cascade of dash warning symbols and bleeps, records it on their smartphone, just in case their dealership finds the fault has fixed itself. I have made such a video in case of a dispute.

I can't remember the exact details now, it was a long time ago, but when I was managing in the powertrain engineering department at a car manufacturer there were strict rules/laws for cars sold in the USA regarding emission compliance. If there were more than a handful (3??) of the same failures which affected emissions significantly we were legally required to do a recall and fix all potentially affected cars (batches of components etc). I assume safety related systems had similar strict rules.
I'd be surprised if a manufacturer could get away without doing something similar here in the UK. Presumably other European countries will be affected too, though of course we are now "free" of having to comply with EU regs which might protect the consumer, our govt can do what they like more or less.

I have just visited my dealer today and the full price for repair would be £1797.34 less any goodwill adjustment from Honda. The garage expect there to be many more cases at other dealers, maybe 100's based on extrapolating their experience  ( one source says that there were around 130 dealers in June 2022). Needless to say I (and I expect many others of you) am not going to just accept a small goodwill adjustment. Apart from phoning Honda Customer Care and awaiting an update, I have also sent Honda UK a long letter by post describing my situation as a long term careful owner (I used post since on their get in touch box only 500 words were allowed - nowhere near enough ! - and I didn't find an email address at the time ).  I also added my views on the broader situation - mentioning the Japan recall with an admittance that there was a manufacturing fault, numerous other owners with the same problem, the effect this could have on Honda's reputation and the fact that general publicity about this was needed for all other owners- a UK recall in fact. Also today I have been given one example of an owner actually experiencing the fault whilst driving in slow moving traffic. This really is potentially a massive safety issue.

A lot of people had problems with Ford's wet belt system which was rapidly deteriorating and pieces of belt would end up clogging parts of the engine. After a lot of bad publicity, Ford finally caved and offered to upgrade the belt for free, for all cars, even if out of warranty. ( as far as i remember )

Problem was, they didn't pay back people that repaired the issue themselves, or even worse, had their engines destroyed.

My point is, the time to work together and make bad publicity for Honda is now, not later.

Hi All.

First of all thanks for all advice and comments.

I notice that since my post there have been more joining the “Brake Failure Club”.

My update is that, through the Dealership, I have been offered £444 by Honda UK as a goodwill gesture and the part will (supposedly) be here on the 19th April.

I have the phone number for Honda UK Customer Relations and will be phoning them regarding this issue. I will also request an email address so that I can confirm these issues in writing.

I saw a bit of The One Show tonight which now incorporates Watchdog. They said to contact them with problems both big and small. This could be a starting point to draw attention to this Honda failure.

My biggest concern at the moment is that my car is sitting in the Dealership carpark deteriorating. They have assured me that it will be fine, but how can it? I also asked what the guarantee/warranty would be on this new part and they didn’t seem to think that there would be one!

How many more before a Recall!

Worth a try, but DVSA seem to have an interesting definition of what constitutes a "serious safety defect". It excludes a defect if "...you’re warned about them by warning lights, noticeable changes in handling and unusual noises". So DVSA may not be interested in this particular defect if the driver gets ample warning not to drive the car, as seems to be the case here. Presumably the logic is it's not a safety issue if the car isn't being driven.

The more relevant bit of that guide might be the next page ...
https://www.gov.uk/vehicle-recalls-and-faults/faults-with-vehicles-parts-and-accessories
... because the failure would certainly cause an MOT failure. So perhaps trying to pin Honda down about whether they've informed DVSA - which might in turn trigger a recall - might be a useful approach?

Post by: BobM on April 04, 2024, 09:01:19 AM
Unfortunately, this issue may not be considered a "serious safety defect" for the purposes of a DVSA- backed recall. From the website, things are not classed as a serious safety defect if "you’re warned about them by warning lights, noticeable changes in handling and unusual noises". All the reports here and on the Facebook page note that the system gives plenty of warning of potential failure.

I've been following the posts, both here and on Facebook. This problem is similar to a manufacturing fault that has been identified and corrected for certain Japanese domestic market (JDM) vehicles. It appears that, over time a seal that has not been assembled properly may cause fluid to leak into the electronics housing causing errors to be detected by the vehicles diagnostics system.

The issue for UK owners (and presumably those in other countries) is whether non-JDM vehicles have been assembled using brake simulator modules from the same batches. Due to differences between JDM VIN codes and those for other markets, UK owners only have  the date of manufacture as a potential indicator. Only Honda in Japan will be able to correlate vehicles with parts batches.

Dealers should inform Honda UK/Europe of a pattern of failures that can, in turn be reported to Honda Japan. If dealers are only ordering spares, and Honda UK do not spot an unusual pattern of requests (it's still low numbers) a potential issue may not be identified. If all those affected by this problem write to Honda UK, using key words and phrases to trigger automated systems (like those used to process peoples' job applications), they may respond.

As a final comment, it would be prudent for anyone getting a replacement to insist on retaining the faulty item, should, at a later date a systematic issue be identified.

At least highlighting to DVSA the problem and extent(see CRV forum) and getting a response even if negative gets the problem into some kind of official footing and copied to Honda may just extract the finger a bit!!

I also noticed that DVSA may not consider recalls relevant if warning lights come up but a MOT failure could be. It should still be worth reporting it and, of course, to various Consumer Associations.
I haven’t yet had concrete evidence of someone experiencing the fault whilst driving just hearsay from a dealer as I mentioned earlier. I will try and follow this up if I can.
Yesterday I registered on a Honda E forum where there are many similar issues and the repair bill being quoted is much higher than the Jazz. I reported our Jazz problems on their forum.
If you are interested there are two links here, the latter one having more detail.

I was at my local dealer this morning booking a service and MOT and said about the brake failure and was informed they they had had 5 so far. They were not happy about Hond's response.

Hi All.

First of all thanks for all advice and comments.

I notice that since my post there have been more joining the “Brake Failure Club”.

My update is that, through the Dealership, I have been offered £444 by Honda UK as a goodwill gesture and the part will (supposedly) be here on the 19th April.

I have the phone number for Honda UK Customer Relations and will be phoning them regarding this issue. I will also request an email address so that I can confirm these issues in writing.

I saw a bit of The One Show tonight which now incorporates Watchdog. They said to contact them with problems both big and small. This could be a starting point to draw attention to this Honda failure.

My biggest concern at the moment is that my car is sitting in the Dealership carpark deteriorating. They have assured me that it will be fine, but how can it? I also asked what the guarantee/warranty would be on this new part and they didn’t seem to think that there would be one!

How many more before a Recall!

I am having a problem even getting my car into a dealer for diagnosis and repair. I contacted my nearest dealer, Marshall Honda Reading, 2 weeks ago and the earliest that they could examine the car was yesterday. Despite my informing them at the time of booking that the car was not driveable they turned up to collect the car without any means of transporting it to the garage which is 12 miles away. I was told to contact a breakdown company to organise transportation. Unfortunately the Hondacare breakdown cover expired at same time as the warranty 6 months ago, something I had overlooked. I have since been totally unable to contact Marshall Honda by phone to rearrange a diagnosis and repair. I have now booked it in with the next nearest dealer, Maidenhead Honda they also are unable to collect so I have booked a local breakdown transporter, at a cost of £160 just to get it to the Maidenhead dealer which is 20 miles away. The earliest they can examine the car is next Tuesday. Although I am pretty sure what the diagnosis will be I feel I cannot start making too much noise about this with Honda until I have an official diagnosis of the fault, hence more delay.

Thats not good news Chris52, and poor service from the Honda dealer. Do you belong to another breakdown organisation? They may be prepared to carry it to a garage? I am not necessarily advising you to do what I did, but I was able to drive mine a few miles to my local garage after turning the car off and on again - this time with no warning lights and the brakes working.

Unfortunately I was not a member of another breakdown service when the fault occurred. I have now added it as an optional extra to my car insurance but this is too late to deal with the current problem. Although the car is driveable (just), I don't fancy driving it the 20+ miles to the dealer, especially as over 50 per cent is motorway.

Has anyone with extended warranty confirmed they’ve had this issue fixed without charge?

I’ve seen a few posters reporting Honda dealer promised this but haven’t seen anyone come back to confirm it happened?

My 3 year warranty runs out at the end of this month. I was going to keep my 21 plate Jazz and extend the warranty, but given the brake issues I’m becoming tempted to trade in for something newer/different unless the fix is guaranteed gratis.

Well it’s not turning out to be a good response from Honda re the 8 failures on this forum alone ! As I have been waiting since start of March for the replacement wiring loom for my 71 plate jazz I was surprised to receive a phone call from Honda uk customer services . As the loom won’t be here until 16th April they have given me a courtesy car until the repair is completed and my jazz is returned . So I’m happy with that !

I had our 21 reg Crosstar  booked in for its MOT the first week of May along with its third service but after seeing the issues with the brake failing and our warranty running out ,we took a HRV out for a demo.

The wife initially thought that the HRV was far to big for her but after the test drive she has said that it will be OK for her.

Back at the dealers they have done me a good deal on a pre-reg 24 plate Advance with 5 miles on it at £6800 off the list price new. We did consider a facelift Crosstar but it would have worked out a lot more,so we pick it up the first week of May.

One thing that I also can not understand is the HRV is group 30A and the Jazz 21A but the insurance for a full year is £80 cheaper for the HRV than a  new Crosstar and even cheaper than our current car!

Seeing as the brake defect appears to be affecting vehicles approaching the 3.5 year old bracket, Jazz and E so far... can we assume that it may well start to affect the HRV soon too, as this model also uses the same brake simulator?

The picture shows 2 (pressure?) switches and 3 solenoids mounted on the fluid chamber. I'm guessing that for the Japan recall, it's the o-ring seals for these items that have been incorrectly fitted (or perhaps not tightened properly) causing fluid to seep into the electronics modules (especially the contact pads for the switches) and causing error messages. The seepage is likely very slow, which is why the fault takes time (not mileage) to occur.

Update:

Last Wednesday, my Jazz was towed by the AA (front wheels raised on a dolly) to Bath Honda. Booked in their workshop for Thursday, to investigate the brake issue. On thursday, I had to keep phoning their service department until finally they told me that the "brake simulator set" needs replacing. They started quoting me the repair cost @£1800 until I reminded them that I was still covered by the 5 year extended warranty they sold me (that they should have noticed from their own computer records). Numpties.

On Friday, Bath Honda phoned to say that the repair had been authorised (under warranty) and the part ordered, with an estimated 72 hour delivery time. The inference being the part is being couriered via air freight from Japan. It should arrive at Bath Honda by the middle of this week. My Jazz should be fixed by the end of this week. Fingers crossed.

Meanwhile, I had to extend the hire car period at my own expense. This extension request involved an argument with the hire company about the increased daily rate they demanded. Originally, the car hire bloke assured me that any hire period extension I need would be on the same daily rate that Honda (AA Relay Plus) were paying for the first 72 hour period; now the car hire company were gouging me at a higher daily rate "because their computer system sets the rate". That's me another £444 out of pocket. The daily hire rate could be another sticky quibble when the time comes to getting Honda UK to refund my loss.

This brake failure saga is stressing me out, as well as taking up a lot of my precious time and energy. A Honda warranty repair should be seamlessly efficient from start to finish, not a battle with Honda UK. I would have expected a loan car delivered to my front door and collected from here as well when my repaired Jazz is returned. Far from it. It is a bus ride and long walk to reach the car hire depot from my home. A similar journey by bus and on foot to the dealership when I eventually collect the Jazz. Plus all the hassle of dealing with the car hire company, a notoriously bad experience anyway. I was carless for the first 24 hours until a hire car became available. I should be entitled to claim compensation for all the inconvenience as well. We shall see what Honda UK has to say about that.

Wow Spodric! For 2 reasons -

The first being the hire care frustration where they can dictate whatever suits them and there’s not a lot we can do about it til later. My sympathies. I am fortunate that we have a second car: my husband is still driving our 2002 Honda Jazz SE which has never caused any problems over the last 20+ years.  ;D

The second being, if this is the same problem affecting myself and others on here, that the part will arrive in 72 hours! I honestly hope this is the case for you. It seems to indicate that the part is available when I have been told it isn’t.

Good Luck

If the repair is paid under warranty, car hire etc are paid by Honda.

If the repair is not under warranty, car hire etc are paid by the owner

Thanks Spodric - an excellent You Tube find. It actually made me laugh at the irony, which was needed since I have now been told by the Dealer that the likely date of the part arriving is not now the 15th April but 23rd. Doesn't sound as if its coming by Air. Also I still have not heard back from the Honda escalation team despite phoning their first line customer service 3 times and sending an email and a letter. The phone calls stated I would have a reply within 3 working days. Perhaps they are having to carefully think out how they can deal with this major problem. I hope they can.

 I would suggest that any complaint  also subtly reminds  the person reading it that they need to pass it to a higher authority to protect their own  back .   Complaints may never reach  someone competent enough to realise just how serious it is due to the Peter Principle'    (The Peter Principle is an observation that the tendency in most organizational hierarchies, such as that of a corporation, is for every employee to rise in the hierarchy through promotion until they reach a level of respective incompetence.)

Someone will decide its their job to protect more senior management from being bothered by such 'minor complaints' and wrongly decide the buck stops with them,  causing horrendous damage to Hondas reputation and profits.     Either someone in in Honda UK or Honda Japan if the complaints reach that far.

When  Senior managment later investigate what went wrong   they will find their scapegoats.  The last person in line  who made the  incompetent decision, and  their manager who may not have been aware but will be criticised for not supervisong properly.   Both could lose their jobs. 

Here is a paste from a post on the HondaEforums   

"FWIW I know someone whose other half is working at a UK dealer. They have seen several failures in the last couple of months (mainly hybrid Jazz models) and they have been in discussions with HUK who are "under extreme pressure to recall these cars".

…. HUK who are "under extreme pressure to recall these cars".

I’d guess that one of the things Honda are wrestling with is deciding what they need to recall. The earlier post from the Honda e owner suggests he managed to fix his car by scavenging a part from a different model. That suggests this is a standard part fitted across (probably) all their EV and hybrid models. So do they all need to be recalled?

The other thing that comes out of that owner’s post is his suggestion that dealers might be implicated by botching a brake fluid change. If there’s even a tiny bit of truth in that, the liability lies with the dealers not with Honda, so why should they recall anything?

All very messy unfortunately.

Post by: Chis52 on April 10, 2024, 04:47:07 PM
I think the wording of the translation of the recall in Japan carries more weight than any potential mis-servicing of the brake fluid. I quote, “… the brake operating simulator, assembly oil used during manufacturing may seep into the pressure sensor due to an inappropriate manufacturing process. Therefore, during use, the resistance part within the sensor may corrode, causing the output value to become abnormal, causing the warning light to illuminate, the failsafe to activate and the force required to operate the brake pedal to be increased.”

My car went in for checking yesterday. Just had a call from Maidenhead Honda to inform me that, as suspected, it is a failure of the brake simulator. Quote for fitting a replacement part, including VAT and fitting costs is just over £2K. They also said the 12volt battery needs replacing, at an additional £190. I said that I was aware that other owners of the 2020 model are suffering the same problem and also quoted the wording of the Japan recall i.e “inappropriate manufacturing process”, they agreed to contact Honda UK, requesting a goodwill gesture. They currently do not know the timescale for obtaining a replacement part.
My next move will depend on the reply from Honda UK.
Title: Re: Mk4 2021 Jazz Brake failure
Post by: Chis52 on April 11, 2024, 10:41:37 AM
Just had an email from the Honda garage who confirmed the brake fault on my car. They asked Honda for a goodwill gesture considering the car is only 3.5 years old and has done 9,000 miles. They have responded by offering to pay 40% of the part cost only. This will be their only and final offer. This means the cost will now be £987.64 inc VAT for the part and £504 for labour. A total cost to me of £1490.64.
My response to the garage was that whilst I not at all happy with this mean spirited gesture from Honda I feel forced to accept in order reduce the delay in getting the car back on the road. Nevertheless I intend to seek legal advice about a claim under the sale of goods act and will also do my best to publicise this problem to various consumer organisations e.g. Which? and BBC Watchdog. I suggest that all other owners of this lemon of a car follow a similar path.

Thanks for the update Chis52.
My charge was to be around £1800 - so nearer £1350 after goodwill- so your dealer seems to be charging more unless they are including your 12v battery replacement in that. Have they given you a potential time scale yet?
I have contacted DVSA with various details about this Honda problem and after filling in a form I have responded to some further questions they asked. They are contacting Honda about it and expecting a reply from them within 7 days. Meanwhile I intend to now send a letter and email to Honda Europe in Bracknell (which Honda UK became some years ago apparently) and address it to a a suitable director after looking up details on Companies House Gov UK. If there are no suitable replies from Honda to this or my communications to them I will then contact various Consumer bodies.

My subject for the email was Preserving Honda’s Reputation in the hope it would be read rather than ditched as a complaint.

Don't know how relevant this is but, a 100 yards down the road from me, there was a Mk4 Jazz in Midnight Blue identical to mine but a bit older. There is now a brand new Yaris in the drive.

I saw the owner today and she was willing to talk to me. She said the Mk4 Jazz will be the last Honda she ever buys and, yes, she had the brake issue which she described as scary and expensive. Her car was off the road for six weeks. "I couldn't wait to get rid of the bloody thing" she said.

Honda need to do a full recall and quick.

My first post.  Pleased to have found you all.

The brake simulator on my 2020 Honda Jazz failed on 10 February and took 5 weeks to repair.  It was 6 weeks out of warranty and had done less than 10,000 miles. Honda Uk gave me a 40% discount.  I paid because I needed to get the repair carried out as quickly as possible.

I took the issue up with the Honda dealership but they were totally unsympathetic.  No courtesy car was offered and there were no updates from them during the five weeks.  When the car was returned to me there was an issue with the steering and I have been back to the dealership several times.  The dealership does not have a complaints process. 

Amongst other things, they told me that it’s very common for low mileage cars to have faults.

Yesterday I received a call from the owner of the dealership, who I have never met.  He told me that he had heard I was an unhappy customer, asked for brief deatils of the issues and then stated that I was now banned, together with my car, from ever going to any of the Honda dealerships he owns in the local area.  Total call time - less than 5 minutes.

I have emailed Honda uk for their comments.

Both Honda reliability and Honda customer service are seriously underperforming with regard to the brake simulator issue. It looks like the legal route is the only one that Honda will respond to.

Would be happy to be proved wrong.

I had to chase them because they are not keeping me informed, but Bath Honda told me today they haven't received the part that was due yesterday. It is now looking like Tuesday next week before they will receive it. The repair of my Jazz will get "priority" as soon as they have the part. Why am I not going to hold my breath ...?

Meanwhile I have extended my car hire until next Wednesday. It is difficult to keep track of the hire cost over the phone, but I estimate that I have racked up over £700 so far.

Just to register my support for those affected and who are now escalating the issue. I bought my car in October 2021 so not sure if it is likely to be affected but it's a nagging worry. Not what you buy a Honda for. The response from Honda UK and many dealers is beyond awful.

I'm fortunate in that, if my car had to be off the road for an extended period, I could manage but many people depend on their cars and the costs of car hire are not trivial to say the least.

Small claims court for me if mine goes this way, I'm sure the judge will prick his ears up at the mention of brake failure. Honda are going to lose a lot of goodwill over this, it's only a matter of time before the media start to run with the story.

Anyone considering any sort of legal action to recoup their costs should ensure they get the failed component(s) back after the repair. And get an independent technical expert to examine them to establish the root cause of the failure.

HONDA COMES GOOD ! – partially anyway because there are still delays.
It seems that my three phone calls plus email and letter (maybe DVSA contact also)  finally had a good outcome when Honda phoned me up this afternoon from customer head office in Bracknell.
There was an apology for the delay in getting back but they say that they will cover all costs, and have informed the dealer, plus if we need a courtesy car that would be provided also. At the moment we have access to another car and currently we do not require the courtesy car. However, that is still an option if required and may be necessary if the mid-June date which now has been suggested by them for the replacement part becomes a reality. Hopefully that will not be the case.

I have every sympathy for those who have already paid or are in the process of dealing with the problem and can hardly believe the reaction of Tinny’s garage. They are completely out of order.

Everyone concerned on this forum should certainly be persistent but try and remain calm if you can! Perhaps use the technique of complaining suggested by Matt Allright on BBC Morning Live/Watchdog.

He suggests the following technique in your complaint

E mpathetic
R easonable
A ssertive
S upported
E vidence
R elentless

Hopefully this will act as an Eraser of the problem.

If you still need to write to Head Office the address is as follows-

Honda Motor Europe  (UK) Cain Road, Bracknell, Berkshire, RG12 1HL
 
or email address as suggested by Daffodil probably for all of the Directors.

If you want  Directors (although I had not reached that stage yet)
Ian Howells is listed as active as Secretary and a Director and longest serving plus 4 others listed as active, although 2 of these were only appointed less than two weeks ago
( including Monsieur Jean-Marc Streng  as suggested by Daffodil). Maybe emails need to be copied to all of them.

Personally I am feeling more confident now that Honda will deal appropriately with all of its customers, but you may need to let them know if you haven’t already. Hopefully legal action may not be needed.
I do suspect that there will have to be a recall now and anyone who has paid would be recouped.

Persistence Prevails!!

Well Done Cobb2! Brilliant news. I also agree that Honda may now do the right thing by us all.

In the meantime let’s all follow by example and use this approach. Write, email, phone, whatever it takes.

As mentioned, I started at the top with the Managing Director Jean-Marc Streng, but I will make use of the other contact details provided by Cobb2 if I don’t hear back soon.

With regard to Tinny’s post - what shocking behaviour from a respectable business! If Honda HO don’t respond, do not give up. The rapidly growing numbers of Brake Simulator Failures is now an acknowledged fault by HO and your Dealership should be named and shamed. The fact that you had steering problems after the repair is a huge concern, especially for a car with less than 10,000 miles. In my email to M. Streng I mentioned my concern about knock on effects of the delay with repair and my car just sitting in the Dealership car park for at least one month, maybe more. Hopefully you will get refunded in the long run, but that doesn’t excuse such unprofessional behaviour from a representative of the whole Honda empire.

Good Luck everyone - get writing and phoning!

UPDATE - I have also just submitted a DVSA Vehicle Safety Defect Report.

Well done guys  (and girls). Although I am unaffected, I sympathise and support you all.

Keep at it: and remember keep notes of all phone calls  as well as correspondence. This could very likely end up as a class action suit and you want to preserve all the evidence.

As for a dealer banning a customer, I suggest trying to have a phone conversation with the dealer, record it all and then go to your local press.   The epithet I want to use for this behaviour would get me banned 8)

Yesterday I received a call from the owner of the dealership, who I have never met.  He told me that he had heard I was an unhappy customer, asked for brief deatils of the issues and then stated that I was now banned, together with my car, from ever going to any of the Honda dealerships he owns in the local area.  Total call time - less than 5 minutes.
...

What an absolute a**!  (pardon my french)

This dealership should be "banned" from any customers to eternity!

The owner has absolutely failed to understand that any justified complaint is:
a) a chance to better themselves
b) a compliment (because the unsatisfied customer thinks they could perform better)

Folks, wanted to express too how bad this situation is for those affected and hope all are resolved acceptably soon when Honda UK finally get their act together. 

I guess I'm in the group with LV who have mid 2021 Mk 4's, so a problem could possibly happen at any time.  From what ive seen, it's unlikely to occur whilst driving, but tends to happen on start up. 

That CAN of course be a major problem if you are away from home, abroad or at the other end of the country when the fault occurs.  So like some others, I'm in a quandary about what to do.  Sit tight and hope for the best, or swap it. 

I'm luckyish in that im covered on the 5 year plan, which has 2 years to run.  I guess on balance, wait and see what happens over the next few months?   :(

I have to say I am rather worried that my Jazz will be affected as I took delivery in November 2020, so maybe it's a matter of time and while we don't do a high mileage we will not be able to manage without it.
Good luck everyone and very well done for your efforts.

Finally got my Jazz brakes fixed. The part arrived earlier this week but I’ve had a battle with Honda regarding the cost.  The original offer was to pay 40% of the cost of the part. After sending an email and letter to the Managing Director of Honda UK I had a phone call from one of his staff offering to pay the total cost of the part but I still have to pay £500 for labour. I have reluctantly accepted this as the car has been off the road for 3 weeks already. I will be picking it up on Monday and will begin negotiations to trade it in for a Kia Niro as I can no longer trust Honda reliability or its customer service.

I have begun putting this information on every Honda related website and forum. I have also been commenting on every Honda advert too. I think it is appalling that a company that has built its reputation on trust and reliability, is treating something as serious as a brake malfunction so flippantly. We all expect some wear and tear, and some parts we know will need replacing at some point... but a brake failure that is now proving to be a prolific issue is not something they should ignore.

As my Jazz is still waiting the delivery of its replacement wiring loom I shall see how it goes once repaired . It’s been standing at dealers since end of feb so see what issues that causes . The 3 year warranty expires end of august so if it’s trouble free I will extend the warranty for two years .

I noticed on the tail gate struts stamped Made in China, I wonder if this brake simulator is the same, it's seems the usual story, not made in Japan, assembled in Japan might be nearer the truth. This is what has ruined BMW & so many of the European companies, using Chinese parts that are rubbish.
 
I was After Sales Manager at a Nissan dealer a few years ago, sensors failing all the time, the ones that came in Renault boxes could even fail again, genuine Nissan stamped Nippon Denso were fine. Renault destroyed Nissan.

Post by: nomis on April 21, 2024, 07:06:53 PM
This issue is really putting me off Honda as a brand. Last September I took delivery of a new Jazz Advance Sport originally intended to replace a 15 year old Fiesta. In the end it was the 10 year old Mondeo estate which went. I no longer needed such a large car, and the Jazz is great at what it does (though the Mondi was a much quicker and quieter motorway cruiser). I'm now in the market for a good used motor to replace the Fiesta (which turned 16 in March).

A relative has an auto Mk3 Jazz which is nice enough but feels gutless in comparison to the hybrid Mk4. As such I was looking for a good low mileage 2020 Mk4 but am now having second thoughts. Apart from a broken coil spring caused by a pothole (which was cheap as chips to have replaced) the Fiesta has never let me down. If it looks at all likely that I'll be facing a fight over a £2,000+ repair bill for what is quite frankly poor design or manufacturing on Honda's part then I'm going to look elsewhere.

Any car can develop a fault. The Mondi suffered a failed sensor on the high-pressure fuel line outside of warranty. It's how the fault is handled that matters. Ford used to throw in free AA cover with a main dealer service, so it cost me nothing to transport the car and myself the 100 miles from where I broke down (at 8pm on a Sunday evening) to my local dealer. The fault was fixed in 3 days and the dealer only charged for the part and the labour to fit it. They waived the cost of diagnosis (which included dropping and flushing the fuel tank) as a goodwill gesture.

I'm in no particular hurry, but if Honda doesn't issue a recall in the next few months then I suspect I'll be handing over my hard earned to a Ford or Toyota dealer rather than a Honda one. And unless Honda will confirm that later model are unaffected then the Jazz I already own could well be looking for a new home too.

Tinny's post about being banned is gobsmackingly awful. Getting legal advice on suing that Honda dealer would be my next move. The dealer deserves it.

Update:

I had to chase them because they are not keeping me informed, but Bath Honda told me today they haven't received the part that was due yesterday. It is now looking like Tuesday next week before they will receive it. The repair of my Jazz will get "priority" as soon as they have the part. Why am I not going to hold my breath ...?

Meanwhile I have extended my car hire until next Wednesday. It is difficult to keep track of the hire cost over the phone, but I estimate that I have racked up over £700 so far.

Update: While this forum was down (Hmmm?) I finally collected my repaired Jazz from the dealership after they phoned me on Tuesday 16 April. Exactly 3 weeks after the brake failure occurred. There was nothing to pay (£2k cost covered by the extended Warranty) BUT I received no Honda paperwork to show that a brake servo replacement warranty repair has been carried out, to add to the sheaf of service records that I keep. One minor grumble is that the Jazz was towed to the dealership in spotless condition; when I collected it, it was unwashed and looked a bit grubby, with signs of having been stored outdoors. That failure to wash the car before collection was poor customer service to add to all the general inconvenience. 

I have received an Invoice via email from the car hire company for 17 days extended hire. The first 72 hours hire (3 days) having been paid under the Honda Care / AA Relay Plus scheme. When I last spoke to the Honda Care call centre they refused to pay for extended car hire beyond the first 72 hours.

I had to wait 24 hours to be allocated a suitable hire car. It was a 71 reg Peugeot 2008 GT auto. I had insisted on an automatic hire car; a reasonable position to take, considering the Jazz is a 2 pedal hybrid. Next, I needed to use public transport (bus) plus a long walk in the wind and rain to collect the car from the depot, although I had a reasonable expectation that it would be delivered to my house. Silly me!

Incidentally, that 72 hour limited benefit didn't cover the second driver, so I also incurred 20 daily charges for her use of the hire car. In total I have paid Enterprise £883.25 including VAT for extended car hire during the 21 day period while my Jazz was off the road getting repaired. As I posted earlier, all my financial loss due to this brake failure is payable by Honda under the Warranty indemnity clause, so I am going to take this up with Honda, because they should reimburse my car hire payment outlay in full. Further update(s) to follow.

Recently checked the brake  actuator repair/replace situation with my dealer (a large West Midlands main Honda dealer) and I am assured that any issue within the warranty period would be FOC.
She wasn’t quite so sure re repair outside of warranty, suggesting that it would probably be the subject of a Honda recall
Having said that, they have only had 1 issue and that was on the pure EV vehicle, not a Jazz.

Good to hear that Honda are covering the whole repair Chis52- as they should and for everyone else. As I reported before the Forum went down last week, Honda are covering all of mine and I have that verbally and in writing. However the delivery date of the part, according to the dealer, has been put back at least another week which is not ideal. I will contact DVSA again to see if they have had a reply from Honda concerning the issue and whether there will be a recall which should make it easier for everyone else who have had to pay, or are currently negotiating or are going to experience this problem in the future in or out of the manufacture's original or extended warranty. Even though some garages may be reporting just a few examples, my dealer  is still of the opinion that the numbers could easily run into hundreds and has already been said, we are just a small proportion of Honda owners discussing it on this forum.
I should also add that its good to get the forum back after a week without it.

I think we would all be interested to hear their response.

I did mention it to my local Honda dealer who had a used Jazz in stock that I would have considered. He played the issue down and suggested extended warranty if I was concerned.

He was throwing in 12 months Honda warranty on a 4 year old car. Honda sell up to 3 years extended warranty on cars up to 8 years old, so if I purchased a 3 year warranty on the 5th and 8th anniversary then I'd be covered until the car was 11 years old. That would cost me £985 a pop at current prices, so around £330 a year which isn't bad.

Then the forum went down so I decided to wait and the car had sold by the time it was back up again.

You are wise to steer clear of the Honda dealer in Reading (Marshalls). The servicing department rarely bother to answer the phone and cannot be relied upon to pass messages. I ended up going to the dealer in Maidenhead to fix my brake fault.

Post by: Spodric on April 25, 2024, 09:46:16 AM
My 2d worth on the brake fluid change query:

My Jazz had its 3 year service last July. That might have included a scheduled brake fluid change. The
relevant box on the Service Check Sheet is ticked. But I can't be absolutely certain about that item.

The electric brake [simulator] [modulator] [servo] [whatever the Dealership likes to call it] failure occurred on 26 March. 7 months and about 3,400 miles had elapsed since the presumed brake fluid change.

If brake failure takes place shortly after a brake fluid change, that could be mere coincidence. I wouldn't jump to the conclusion that there is some kind of causation between the two. It could just as easily have been triggered by a deep pothole that gave the faulty part a sudden shock. Mere speculation, obviously. What most of these sudden brake failures have in common is that they took place on engine start-up, while stationary, not while driving the Jazz.

I pressed the brake pedal while pushing the Start button. Gear selector in P and parking brake on. There followed a series of warning bleeps and symbols appearing on the dash display. I suspect that with my foot on the brake pedal, the corroded sensor inside the brake module had started to give the ECU some pressure readings that were abnormal and/or outside the permitted range, so the ECU shut it down and tried to stop the parking brake being released.

Whatever the actual failure mechanism, the Jazz had become undriveable. Attempting to drive it would be very risky. It needed to be recovered and taken to the dealership ASAP. In fact I had to wait 9 days for a workshop appointment. In total I was without the Jazz for 21 days. Not a good experience.

In my case I didn't get an invoice, only a Service Check Sheet. The Honda 5 Year Care Package (an optional extra I paid for) includes free scheduled services for 5 years as well as the extended Warranty.

All the relevant service, recall work, and warranty records must be on Honda's computer database that only the Dealer can access. Including a record of the brake simulator repair under Warranty, for which I have received no paperwork for my own records.

I like keeping full paper records in my file. This newfangled reliance on digital-only record keeping by Honda is frustrating. It seems to me that it is potentially anti-competitive, inasmuch as it might put the Honda customer at a disadvantage when or if the customer wants to trade in the Honda with a different dealer network to buy a different marque. Without relevant paperwork, how can the Honda car owner prove that all these jobs have been carried out by the Honda dealer?

So any random person can read the car's VIN and find out it's service history? I suspect this is a difference between Swiss and UK data protection laws. No idea what the Swiss equivalent of GDPR is, but in UK I suspect that detailed data about a car's history might be regarded as needing password-protection via an account because it's conceivable that it contains personally-identifiable information.

So any random person can read the car's VIN and find out it's service history?

I'm afraid, that is the consequence, yes!  (and I do wholeheartedly concur with your estimate of Swiss data "protection")

(by my opinion the clearly visible VIN itself is in violation of "my" idea of privacy!)

Your Digital Service record can be checked here: https://www.honda.co.uk/cars/owners/digital-service-record.html

You need to have or create a Honda account.

Right now I have no desire whatever to create a Honda account. This is why:

Today I received an email from Honda UK rejecting my claim for hire car costs.

One risible ground being that Honda UK considers that the repair under warranty is not due to a material or manufacturing defect. Eh? How does that work? If the "brake simulator unit" failed after a relatively short period, and relatively low mileage, requiring urgent replacement, it is most likely because this component had a latent defect caused by a faulty manufacturing process. Honda knows this. We know Honda knows this.

The other ground being that the "loss" indemnity only covers the repair. It does not apply to financial loss. That restrictively narrow interpretation is utter nonsense. I am relying on the plain meaning of Honda's guarantee and indemnity wording. I reckon any Judge is likely to prefer my conventional interpretation of Clause 13 b) ii. Which is badly drafted anyway.

I am supposed to contact Honda Escalation if I am not satisfied. Who or what is Honda Escalation? Has any other ClubJazz poster dealt with them? If so, how did that go?

 I checked my account to look at my service (first) carried out on 20th March. The page informed me that 'We found Digital Service Records for the following vehicle(s)' but further down the page i was informed 'There are no services associated to this VIN.'  There was no information about the service on the page. I'm going to call my dealership later.

I have just checked mine, and it is all there. The first service at 12350 miles gives a full report, and interestingly there is this in the list:

B Inspect brake hoses and lines (including VSA lines
Check master cylinder and VSA modulator control unit for damage and leakage.

Was checked and OK'd. Phew.
Also under the 'recalls' check box, there was nothing to indicate any.

If honda are paying for tbe replacement defective part then the non delivery of that part is causing the need to hire a replacement. Simple Honda should pay if that delay is weeks and weeks . You cant buy the part elsewhere .My dealer would provide a courtesy car under such circumstances even if Honda Uk wont ! Thats why the family owned dealers keep their valued customers !! You absolutely wouldnt get this treatment with toyota or lexus !

I agree that a good dealer would and should look after you. However as already mentioned on here, it would appear that Toyota/Lexus are saints. They are not, and a visit to their forums will confirm. I have had Lexus for years and the same criteria as above apply, some dealers are good others aren’t and they experience very similar issues, including angry forum members.

Absolutely agree with the variable standard of dealers, irrespective of car manufacturer. However, a major point with this brake failure is it is occurring just outside the standard Honda 3 year warranty and from numerous posts it seems Honda certainly at first see this as a customer problem not theirs. I believe that provided they service your car regularly, Toyota provide a ten year warranty which is a definite plus.

That is correct, but Honda offer a 5 year warranty  care plan, which I have, plus I expect it is possible to extend that also. The Toyota 10 year warranty is not free but paid on top of the service charge. Each manufacturer will offer their own options, for example the Honda 5 year service plan is fantastic value.
All manufacturers warranty period, whatever length, is definitive, and if something fails outside it is then your problem. I do think in this case as it is potentially safety related and affecting a larger number, Honda should warrant it, and take responsibility.
The other issue of course is then the discussion that takes place as to whether the failure is a warranty issue, and I can assure you Toyota and Lexus , even with their 10 year cover have issues.

There is no extra charge for the Toyota warranty extension. So long as you get the car serviced at the appropriate time, another year gets added on. Not sure what you mean by 'paid on top of the service charge'.

The Toyota manufacturer warranty is 3 years. The extended 7 year warranty offered , if  it is serviced at a Toyota garage is provided by an independent insurance company and not as good as the 3 year. The annual cost of this insurance is factored into the service cost, plus if you need to have repair work done that is not covered, you will pay full main dealer prices. A service costs less without the extended warranty cost, for example over 10 years old,   by negotiation.
The point I am trying to make is that Toyota /Lexus are like Honda or anybody else , only as good as the dealers. I have a lot of experience with both, and a visit to their forums will confirm.

I'm not sure where you are getting your information from. As a Toyota owner, with an 8 year old car, 7 years with me, this warranty just works. There is no mention of a third party and there is no option to get a cheaper service without the warranty extension.
