no heated rear screen again for me this morning. although its mainly getting short 7 mile drives at the moment, half of those with the lights on, and i havent used it all weekend.
It is daft that it disables the rear screen heating, but allows you to use the heated seats. It is also daft that it allows you to lock the car with the ignition on and it'll sit there while the battery runs flat. (i havent done this myself, but others have) It should just switch off after 10 minutes... why would you want to leave the car in that state?
It seems to me, having looked at the various comments on the forum, that the car can vary the charge current into the battery, so even when the the alternator is running (as seen by those wish volt meters connected) it still isnt necessarily charging the battery very much. It "seems" to be aiming for 75-80% charge level, rather than fully charged. all in the name of efficiency i suspect. This obviously isnt quite working well enough, as reports of taking it for a long drive doesn't seem to fix it. If the car changed it all the way up, then the occasional longer drive would likely mean those with a short commute would have less issues.
I dont have a driveway, so charging my car regularly would be a bit of a faff to be honest.
i can live with it, and still love the car, but if after the 3 year deal is up its still an issue, it might make me look around a bit... not to say i wouldnt get another one anyway, but if i was on the fence, it might sway me.
