Yeah, I've driven a Stop/Start before, but this car doesn't have it, the engine is definitely still running at a stop. It does actually feel a little bit like Stop/Start but with a very slight lurch forward.
The dealer does seem to want to help, but it is a bit worrying that they claim to have done all this work and the problem is still there.
I think if the dealer can't get to the bottom of the issue before my 30 days, I think it'll go back.
