What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I almost got hit by on coming traffic, but my car hit the curve first stopping an accident from occurring I have replace window motor twice and they have went out again now. And I have also replaced window motor buttons for a second time in the past 3 years
Started with the fuel gauge moving in wrong direction into speedometer. Empty is at 110mph. Speedometer stuck at 55mph while coming into town and needing to reduce to 35mph with my children in the car with me!
Clock and radio reset. Car can easily be restarted, but clock and radio must be reset. Has happened many times. Dealer was unable to locate a problem on several service appointments.
My son was driving down road car shut off and everything locked up and had no power. Afraid it could happen while driving at faster speed and could cause an accident.
My speedometer goes down to zero when driving. The speedometer will start working again after the car sits for a few hours; however, now the speedometer will not work at all if the car has been sitting outside in the heat. It is very dangerous to be driving and not know what speed you are going.
Rear defrost would not work for two days and on the thrid day tried if again, then a few minutes later, my rear glass exploded.
2005 pontiac sunfire with 27,000 miles. Rear brake retaining spring broke while driving. Broken parts fell into the drum causing noise and excessive heating of the drum. Had to pay for the part and fix it after waiting three days to get the part from the dealer. Old part is available.
2005 pontiac sunfire continuously stalling. Has been back to dealer four times, going back for fifth. They cannot find a problem. This creates a very dangerous situation, and nearly resulted in accidents when it stalled as I attempted to clear intersections.
