2004 Pontiac Grand Am Owner Comments

problem #4

Aug 012006

Grand Am 6-cyl

  • Automatic transmission
  • 46,095 miles


While driving in a city area the accelerator stuck causing the vehicle to continue at a high rate of speed even with the brake fully depressed. The driver of the vehicle was able to pull into an empty parking lot, pull up the emergency brake and turn off the vehicle. On restarting the motor, the engine continued to rev at a high RPM. On checking the throttle body, the throttle appeared to remain partially open without the accelerator foot pedal being depressed. After manually pushing it back in place, the problem could not be duplicated, and no apparent cause was found. Appears to be a defect that caused problem to occur intermittently.

2004 Pontiac Grand Am trunk popped open and raced out of the drive way while in reverse and foot was not on accelerator. The consumer put in a claim to GM, however the claim was denied. The local dealer stated they couldn't find a problem with the vehicle. The consumer stated a recall was issued which described exactly what he experienced.

Grand Am 4-cyl

  • Manual transmission
  • 9,523 miles
Beginning in December of 2004 the vehicle while driving through a heavy rainfall had the accelerator stick and the car had to be pulled to the side of the road and turned off. At various other times between December of 2004 and 3/28/05 the vehicle displayed a stuck accelerator. On 3/28/05 vehicle was serviced at bommarito South for this same issue, during that service visit, they couldn't replicate the issue but they inaccurately reprogrammed the PCM following the tech service bulletin #04-06-063 (in reference to idle flair). This service did not correct the problem on 4/08/05, vehicle was serviced at bommarito South for the same issue again and the throttle body and accelerator cable were replaced. This apparently also did not solve the problem. On September 9, 2005 with approximately 9524 miles on the vehicle, while slowing down in 5th gear and leveling my speed out at approximately 30 mph, I released the gas pedal and engaged the clutch in order to downshift. When I did this, the RPM level on the vehicle climbed to approximately 4000 RPM and remained at that level. In order to get it to come down from the high RPM I had to pump my gas pedal several times. (I will point out that there had been a heavy dew that morning, I am not sure if that had a bearing on the issue, but considering that this situation has also occurred during heavy rainfall I feel it is worth point out). On 9/12/2005 the vehicle was towed by GM to the bommarito Pontiac South dealer again, this time the dealer stated that they couldn't replicate the problem but that the vehicle was suppose to do this.. it sounds to me that they don't know what is going on.

While accelerating the accelerator pedal stuck. Consumer managed to decelerate the vehicle to shut down, and restart the ignition. Dealership was notified, but did not resolve the problem. The consumer stated the vehicle will get stuck in a very high idle causing the tachometer to almost enter the red zone. It was most noticeable went he clutch was depressed during a heavy down pour, however it happened it occasionally happened anytime. The dealer stated a technical service bulletin had been issued regarding the idle flair, however the consumer thought their diagnoses was incorrect. After numerous conversations, the dealer finally replaced the entire throttle pedal assembly and throttle cable. The consumer stated the problem still has not be resolved.
