Mk4 2021 Jazz Brake failure

[Lord Voltermore]

I think the replaced part has sensors and stuff and will be integrated into the cars  clever electronics . There may be a period when the car has to be powered up in the workshop with a diagnostics computer plugged in reprogramming it and running tests. In addition to a road test to check the brakes actually work.    And possibly some recalibration after the road test etc.

I have noticed that periods when the engine may be running, but the car not moving  ,such as when listening to music, or  learning  advanced controls  (playing with your new toy    ) it can quite quickly make a big difference to recorded average mpg.

Yesterday our brake servo feel simulator was replaced. Since our dealer in Toruń (and also the one in Bydgoszcz (28 miles away) disappeared, we had to drive to Gdansk (190 miles in total for a visit to the dealer.... ).
Luckily there was a large shopping mall nearby, so we didn't have to spend more than 3 hours at the dealer.
The dealer really did his best: without asking, they also provided the navigation with the latest map version. Maybe they saw us as a possible new (distant) customer...
Our mpg went also bonkers, just as the average speed.
Oh... and all this happened without having seen one or more letters from Honda, only two phone calls. One to Honda Poland and one to the dealer.

To be fair I was surprised my mpg only dropped by .3 and my husband and his heavy foot took it there 🤣

At my last diagnostics they absolute trashed my mpg and it never got better until they replaced the battery harness. Or whatever the hell was wrong. There’s been so much I can’t keep on top anymore 🤣

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

Had my brake simulator recall done over a month ago, and all has been fine since. 

I noticed one thing tho, don't know if anyone else notices this, that is, the brake pedal after the recall seems to have more feel.  But at very low speeds on inclines, I find I need to put a lot of pressure on the brake to stop - a bit odd.  And thats in D or R

We have just had our 20 plate done by North Wales Honda (dealership now being run by a different company….that’s another story!).
All seems fine so far.
The dashcam was left running during the workshop visit but for sooooo long that early footage was overwritten. All it’s mostly showing is that the car sat around for the last hour or so with no technician actually doing anything…..possibly he’d left it running on a diagnostic testing sequence (or maybe there was nowhere around the dealership to park the car!?

I have my 20 plate CRV going in on Tuesday for brake simulator module replacement too so will see how that goes.

The dealership has appointed 4 replacement “Honda” technicians which is a bit concerning as a consequence of the new business transfer. The dealership has just opened up a brand new £2.1million KIA showroom and contentious car park on the other side of the road.

Watch this space!

Had the Brake Module replaced on both our Jazz and CRV hybrids.

Frighteningly pricey just for at £1,578 just for the module itself.

Thanks to ALL who pushed HONDA back on this one!

Aaaarrrggghhh.
Setting off on holiday tomorrow in the car. Attempting to move car for a pre-trip wash and dash lit up with brake failure messages.  Why today?  Not sure my heart can take this.

[Kremmen]

Not what you want 

That reminded me to check Honda UK and my MY22 now appears on the recall page

Turned out it was the 12v battery issue - complete fail. Despite having 5 year warranty, Honda told me that the 12v battery was not covered. Thankfully, the AA had a new one on the va (with a five year warranty!) and charged £134.  Honda wanted £177 and no extended warranty.

Mine's booked in for the recall work on April Fools Day 

Takes 2.5 to 3 hours apparently

They want mine all day from 08:00

Kremmen,

Our Jazz was in most of the day and they had our CRV all day with collection the following day.

Additionally to that the workshop is under severe pressure due to a complete change of ownership and NEW staff. (North WalesHonda)

Worryingly with the Jazz they asked me to bring it back in the next day because they thought they may not have tightened up an adjustment bolt on the engine properly (they had actually done it right!)


Any North Wales customers out there beware ….don’t leave your car on Argyle Street by the Kia dealer due to total lack of parking; you will get a parking ticket!

This new ownership isn’t boding well at the moment

That sounds like a lot of hassle to me and not what I’d expect from a Honda Dealer

Hopefully the new ownership and new staff will eventually start working together to provide great service for owners

In the meantime however is there another dealer you could take your car to?  That will give the original dealer time to recover!

[RuthieB]

Next nearest Honda dealer from Llandudno is Cheshire Oaks north of Chester about 50 miles away.

Heard another story about my friend taking in his mark 3 in  to Llandudno for brake repairs to be told that the work had been done in replacing his faulty brakes and replacing the 12volt battery.@ £465 duly paid
On taking the car home noises still persisted so he took the car back the next day to find that they had not actually done the work.

I despair!

Does anybody know how they get in touch with you if your car is in line for the recall? Is it a phone call, email. Missed a call a week or so back from my dealer. They haven't been back in touch.
