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!

I own a 2000 pontiac sunfire and the car shuts off while driving at 60-65 MPH. Car has been taken to the pontiac dealer, they have not been able to find anything wrong with the vehicle, also left the vehicle with another mechanic who drove the car for a couple of days but it did not shut off. I am concerned because I was driving on the highway in the fast lane and the car just decelerated and stopped.
