This has been a great and comfortable car, except for some strange electrical problems: Car can not be locked, because alarm will turn itself on and off after a period of time. Interior lights turn on and off while driving, and turn on, instead of slowly turning off, when car is turned off. CD player only available now and then, depending on what the car 'feels' like. Radio will stop playing and On-Star starts calling for emergency assistance for no reason whatsoever. Remote Key entry works on all doors, except driver door, which remains firmly locked.
