Honda Jazz Mk4 2020 - / Re: Mk4 2021 Jazz Brake failure
« Last post by Lord Voltermore on Today at 12:38:53 PM »
I am a bit confused by the chassis numbers on the list on page 4.   They show 7 digits.  My car appears to end in  6 digits    2021** 

If I ignore  the first digit  this appears to put my car within the GR3 1200001  -GR3 1218092
May21 3rd  year of Reiwa  (21 may 2021) to 2 Feb  4th year of Reiwa   (2 feb 2022)  which is about right as the car was delivered in October 2021.   

Is this correct?

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.

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 .

Honda Jazz Mk4 2020 - / Farewell to the Jazz, hello to the HR-V
« Last post by Pogglefish on Today at 12:33:59 PM »
So I traded my Jazz in for an HR-V last week.  I was actually planning to get another Jazz, but a combination of deals available on the HR-V, several new ones that they wanted off the forecourt on 24 plates, and the particular one that I bought being in a the (let's say) distinct colour of Sand Khaki, actually made it about £15 a month cheaper for me to lease an HR-V than a new Jazz.

After one week, my initial thoughts on the difference between a Mk.4 Jazz and the current HR-V are as follows:

- The HR-V is a lot more comfortable.  Like the Jazz, the steering wheel still doesn't come out quite as far as I'd ideally like, but the seats are much better.  It is also a little quieter insider at high speed.

- Whilst, seats up,  the boot in the HR-V is not noticeably different in total size to that of a Jazz, it is shallower and therefore has noticeably more floor space, so bags do not have to put on top of each other as often.  Seats down, there is quite a bit more load space.

- The HR-V has three driving modes (sport, normal, eco) as compared to just two (normal and eco) in the Jazz.  The only use for sport so far found is when it is necessary to accelerate quickly on (say) a short slip-road which brings me to:

- The HR-V can accelerate faster than the Jazz, but both cars are equally happy with the high-speed cruise.

- Being a bigger car, the HR-V's fuel consumption is slightly worse; I averaged high fifties in the Jazz, low fifties in the HR-V so far.

- The HR-V has a better stereo.  Actually I think the unit might well be the same, but it has more and better speakers.

- The HR-V has some toys that the Jazz does not have, but none of these are things you could not live without (hill descent control (why? it's not a 4x4 and doesn't pretend to be), dual zone air-con, automatic tailgate, air vent diffusers and possibly a couple of others so minor I have forgotten them).

- The HR-V does not have silly plastic fins on its wheels.

In summary therefore, the HR-V is very slightly better than a Jazz.  It is not, in my opinion, £8,000 better than a Jazz (which would be the difference in full new price, top of the range to top of the range) but if you lease/PCP your cars as I do, and you can get an HR-V for less per month than a Jazz with all the care packages thrown in for free, the change is probably worthwhile.

Get a used Honda one same spec from your local breakers yard. The Chinese made electricsl parts are not worth the effort.

I certainly would not buy a car with that fault. Period.
If the manufacturer does not resolve it free of charge, I will never buy another Honda.
And not having repair kits available for a common fault is disgusting.

UK consumer law is quite clear on this issue with cars..
Honda should be ashamed of their actions or lack of them.

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!

I have no knowledge of the mirror but I will make some theoretical suggestions  - which may be wrong. :-[

A few mk4 owners have had problems with the right hand mirror .These were replaced under warranty. Some have solved the problem themselves with carefully targeted  light lubrication.  But I am not sure this is your problem.

How does the electric motor 'know' when it needs to stop?  If there is only one motor and cog wheel  it may run backwards and forwards  by reversing the polarity so there may be two stop positions.  There may be some sort of position sensor  in the mirror that cuts power when the mirror is fully extended or fully retracted. Maybe this has become desynchronised or displaced.  But the mechanism may be built in to the motor and not immediately obvious  , or tripped by a lug on the cogwheel  ,that maybe worked when first fitted  but not tripping it now.        Its also possible the broken cogwheel was the result of the motor over running previously ,  not the cause of the problem.  It might be able to tolerate  a certain amount of over run for a while without breaking or wearing out.   

Another possibility is that power is cut  by some sort of electrical device when it senses   the motor is under strain because the mirror has reached its position. It would also give protection if the mirror is obstructed in some way, such as by  ice.  Maybe if there is such a device it has  failed .  But it need not be in the mirror itself,but elsewhere as part of complex electronics.   :(

Does the mirror work ok if you use the manual  mirror fold switch in the drivers door?  Could the switch be faulty.? But i would have thought this would affect both mirrors. 
Does the passenger mirror  motor stop running as it should?   
These things might help you isolate the cause  .

If you dont mind some extra work, you could as a last test  unplug the mirror wiring  and using extension wires  connect the left mirror to the right side wiring   and then vice versa.  If the problem migrates to the other mirror  the problem may be central to the car internal  wiring. If the same mirror continues to be faulty   the fault lies within in the mirror and it may be easier  to replace it.  You may be able to get a second hand one for not much more than you paid for the cogs.  There are  used parts search web sites. Enter what you need for free and various breakers yards  send you their price. A bit like a personalised ebay listing. 

  Or dont bother with the rewiring trick and replace it anyway.    If it  later proves both mirrors are ok you could  re sell one  and get some of your money back.

Sounds like Honda need to get these kits sent to the UK asap knowing they are going to be needed

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

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.
