2003 Pontiac Sunfire Owner Comments

problem #4

Feb 212006


  • Manual transmission
  • 87,000 miles


: the contact stated intermittently, the vehicle stalled while driving. There were no warning lights when this occurred. The vehicle was put in neutral then restarted. The dealership was unable to duplicate the problem. Also, the clutch failed on the vehicle twice. The first time occurred while parked and the dealership replaced the clutch pin. The second time, 3 months later, while driving the clutch went to the floor. The vehicle was towed to a mechanic where it is currently being repaired.

Bought vehicle brand new and it has been in the repair shop 15 times for the same problem. It is dying at random for no reason and will not start back. Sometimes it takes up to 20 minutes or longer before it will restart. Mechanic had no idea why this problem happened. The car was taken to different dealership, but no one could figure this out. Two weeks ago the car was subjected to a pressurized test. Consumer has the car towed on 5-31-2005 because it died, and did restart. There have been lots of problems to try to correct, but nothing worked. The car was kept at the dealer for up to two weeks at a time.

Sunfire 4-cyl

  • Manual transmission

Vehicle intermittently stall on the highway without warning. The vehicle has been to the dealer eight times and still hasn't found the problem. Since the last correspondence the consumer was involved in an accident when her vehicle stalled. The vehicle was taken to a different dealer who informed the consumer that a service bulletin had been issued in November 2003 regarding this problem. The consumer was never notified of a recall from the other dealer.
