Don't sweat it. If you live by the forums or by heresay, you'll be paranoid all the time. Just enjoy the car. Not everyone will have the problems that people talk about. They're also less apt to mention their appreciation when the onboard computer informed them that a light was burnt out or something. The flip side is that electrical systems nowadays are so advanced. And if something happens, then like they say, shit happens . . . but it can happen to any car.
