Honda Jazz Mk3 2015 - 2020 / Re: Carb flooded.
« Last post by embee on Today at 08:53:48 AM »It's not actually "flooded" (technically), rather the fuel enrichment used for cold starting results in some wet carbon which normally burns off in the first few seconds of normal running. Cranking fuelling and afterstart enrichment ramps off within a short time, something of the order of 10sec or so, and the combustion chamber will be hot enough to clear moisture and wet carbon after maybe 30sec.
The general guide is not to start and run an engine, especially from cold, for less than 30sec or preferably a minute.
In industry we did specific plug fouling tests consisting of repeated cold starts and stop cycles. We measured plug resistance and you can plot the trend and predict quite accurately how many cycles will lead to fouling. Our problems were mainly to do with the production and delivery practices of moving and shipping cars, there were many starts without the engine ever getting properly hot.

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'.

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.

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.

I told him about the soy issue and he said bizarrely it is all over the Rover owners forum about rodents eating through wiring harnesses, all of a sudden, so it affecting them as well. I don’t think soy is involved though !

Does it happen when you hit a pothole on one side of the car only? Or both?
