Car has had numerous problems since day one. Brakes chatter, overheating, service engine light, cd player and speakers did not work. Now it stalls with no warning at all. Stalls at 70 mph going down highway. Has stalled while driving 3 or 4 times in the past two days. Checked out at service station on computer, and shows no problems. Have read many complaints here about the exact same problem. Bad fuel pump or something is causing car to stall. Then it takes from 10 to 15 minutes to start again. Some days it just won't start at all. Have had car checked many times, and no one can seem to find the problem. Anyone that can help here"?" I think GMC owes many, many consumers an explanation and repair of this very serious and potentially dangerous problem!
