Jim, Diane may well be right....if you don't happen to screw on the gas cap tightly after fueling, that damned check engine light will light up, and it may take a couple cycles of starting, driving and stopping the car before it will go out. But now Onstar has conspired with the dealer to send you for a diagnostic which may run you a few hundred dollars. I don't care for dealerships much, though with a new car you almost have to play their game or risk the warranty being voided.
