Mk4 2021 Jazz Brake failure

[JJazz]

Can it go anytime or after so many miles or what?. My car is registered November 2022 but only done 4,250 miles.

It appears to be an age related issue. The average seems to be 3 years, but there has been a 4 and 5 year failure on this forum. Honda seem to be staging the recall notices at 3 years, so in the wider community it seems this is the average time for failures.
Mine is a 22 plate ('PS' VIN) and I am just touching 29k, so not related to mileage.

Given that this is presumably brake fluid passing a seal ?

I wonder if other factors come into play :

Mileage
Age
Using D so more braking
Brake hold (how much pressure does it apply)

Not sure about 3 years recall. Mine is a MY22 from Sep 21 and not on the list yet

3.5 years seems to be the average time, but that is only going by the reports on this forum. I don't think mileage, or how the car is driven plays any part in this failure. I imagine it is the seal perishing. The unit is not very big, so even the tiniest amount of oil getting into the electronic bit would cause issues. Therefore I think the seal is actually degenerating over a period of time, and that is when the seepage begins. I have had a few classic bikes, were previous owners have used cheaper seals and gaskets from non original suppliers. These all perish and either crack or split over time.

Mine went after 4 1/2 years (12000 mls)
Had Honda jazz for many years without problems until upgraded in 2020, since then 2 punctures (first in over 20+ years), new windscreen new wing mirror and finally brake simulator.
Hopefully I may get a few years trouble free now.

Just when I thought it was all over, brake recall done but air con leak now,  another warranty visit in a few weeks.

3 warranty repairs in 2 months is a joke tbh.

I’m so sorry you are having issues with your Jazz

The only good thing is that it’s all being sorted under warranty

Can I ask what mileage you Jazz has done?

Just hit 19k

Got the recall done, also did the annual service while I was there. Car seems to be running fine, hopefully all is well!

Mine was done earlier this week (but not the service).  I was surprised that they used over a litre of petrol (at 3.9mpg) while they were doing it.  If you use the Honda+ app, can you see how much fuel they used?

Definitely didn't happen to me, I barely had any fuel when I left the car and would have noticed a difference.

They have to test drive the car don't they??

I was told years ago that any brake work must be tested on the road before handing back

Yes, it looks like the car was driven at 24mph at some point so that was probably the road test.  However, the time that it was powered up was over an hour-and-a-half, hence the fuel consumption, and the figure of an average speed of 0.3mph indicates that it wasn't on the road for much of that time. The fuel consumption of 1.2 litres during that time is equivalent to almost 100 miles on the road.

Incidentally, I'm not complaining, I'm just surprised.

Maybe MikeRO's garage chose to put a litre of petrol in rather than risk running out while out on a road test  etc, or handing the car back with almost  no petrol in it.

Got the "update" letter about brake sensor issue today in Italy.
My Jazz is a 2020 GR VIN.

I had mine repaired but was surprised that when it went in it was averaging 66.4 mpg when I picked it up it was averaging 45.3mpg. But the total milage was still there so it hadn't been reset. I though it'll was strange. But apparently now I hear others have the same.
