NHTSA complaint #10055279, filed 2004-04, 40,000 miles“Vehicle shuts off while driving & will not restart. Dealer has been unable to identify the cause. Has replaced ECM & attached a vehicle data recorder in order to hopefully locate the source of trouble. I have been in dangerous situations, traveling at high speeds on busy roadways when the engine failure occurs. I am given no warning, nor am I able to restart the car. I have had the car towed 4 times & I just bought the car a month and a half ago.”
NHTSA complaint #708695, filed 1999-07“While driving, consumer heard a loud dragging noise and was later informed that the noise was caused by faulty ball joints, also dealer replaced the front axle shaft to replace the inner tri-pod boot. The passenger front wheel had leaned in at the top, and the engine had an oil leak. The consumer has requested reimbursement for the monies spent on repair.”
NHTSA complaint #566722, filed 2002-07“Vehicle stopped without any reason and was unable to restart it. This is a hazard if it had occurred on a freeway or other fast moving highway. It seems this is a cronic problem with this vehicle as there are several other complaints filed. It is time that Gmc determine what causes this problem and corrects it. At this time the vehicle is still at the garage and I don't know what they say wil be the problem.”
NHTSA complaint #10030314, filed 2003-07“Date given is the first incident. Engine quits for no apparent reason. It has happened at different speeds and different weather conditions. Dealer cannot find reason. Contacted GM and they just called the dealer. I am fearful that it will happen on the freeway and will cause an accident and someone will get hurt. Dealer says there is nothing they can do because they can't find the reason and they can't replace parts they don't think are broken.”
