What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Reading about the recent gm recall for automobiles stalling out when driving, triggered my memory of my former pontiac. On at least 3 occasions, this pontiac had stalled out in a similar fashion. The first time, I was driving on the highway at a speed of 65 to 70 mph, and the car just shut down.
The electric door locks started draining my battery & then ruined my alternator. I removed the fuse to keep it from ruining my new alternator & battery,. I was manually opening & closing my doors. Now 3 of my 4 doors will not open. They won't open with the key or by pushing the door lock button.
While driving 65 mph rear driver side tire blew out. As a result the vehicle lost control, and the tail lights busted out.
The consumer had no brakes when he apply his brake pedal. Please provide additional information. Ts
At 65 mph the tread peeled away from tire causing a loss of control.they tire kept its air and I drove on the belts for aid.there was 50000 miles on the tire but they (the other rear was the same type)had good tread on them.I bought two new tiresthe next day.there was no accident due to the sparce traffic on the road.
Was going around a corner at 45mph when subframe separated. Driver heard a loud noise. Managed to pull over. Steering wheel was very difficult. Had vehicle towed home.
Vehicle was in storage for several months, first drive on the road the brakes failed, while applying the brakes the anit-lock system engaged returning a rock hard pedal but did not engage the brakes, after several pumps, the pedal released and the brakes engaged. Nlm
Power locks are defective. They lock on their own when the vehicle is started, and sometimes cannot be unlocked from the outside with the key, this caused a child to be locked in the vehicle for hours. Dealer has been contacted.
