When I took my foot off the accelerator pedal, the pedal stuck and did not return back up. Instead it stayed down as though it was still being depressed causing the engine to rev. I had to physically grab the accelerator pedal and pull it towards me to try and return it back to its normal position. This happened on several occasions and I had to have the entire accelerator assembly replaced, I called GM only to be told that the recall on this known problem was for the 03 Grand AM models, not the 05 models. I wonder how many people have to die before GM decides they are better off financially to recall the 05 models?
I took my car in for the recall last Wednesday, October 29, 2014 after receiving the notice to a GM dealership here in denver, co to fix the ignition problem in the recall. I was told by the service center they cant fix the problem with my ignition without the original set of Pontiac keys from the manufacturer. I bought this car from drivetime dealership in aurora in 2011, and the sets of keys that I received for the car were cut keys from the local hardware store. Right now I cant get this fixed, this car is dangerous to drive, the fuel line shuts down at any given random time. Im making payments on a car I cant drive, its unsafe. I was hoping the recall would fix this problem. …
Regular occurrences started at 120K miles, these are all issues which previously complaints have been filed by current 2004 Grand AM owners but have not been corrected and I have called every 6 months filing these complaints. 1) gas fumes are coming in the car when it is running or sitting still idling, 2) blinkers start blinking on their own around 80 degrees f outside temperature, mechanic said it was because grease in steering column becomes thin and shorts out other wiring causing the smoke (fire) which comes from steering column, this occurs every summer to fall when temps are 80 degrees or higher), 3) horn does not work, mechanic replaced horn mechanism but it did not fix the issue & I AM concerned the air bag system won't work either since they are inter twined in the steering column, 4) the dash is warping, cracking and breaking horribly, it causes a sticky haze (gas) on my …
My son was driving this 2004 Pontiac Grand AM and noticed gasoline odor/fumes coming into the vehicle cabin area with the HVAC system operating. Upon inspection of his complaint we noticed fuel leaking from the fuel pressure regulator. This fuel leak was minimal when the engine was at mid temperature but became worse when the engine reached operating temperature. During additional diagnostics we also noticed when the engine was started up cold that the fuel leak was easily identified and leaking profusely. We promptly shut the engine down contained the fuel leak and disconnected the battery until the fuel leak could be repaired. The fuel regulator appears to be the original OEM installed component. We replaced the fuel regulator assembly and the leak has now been corrected. The faulty component appears to have a pinhole leak at the top hat area or some type of porosity. …

Tl* the contact owns a 2002 Pontiac Grand AM. While driving at any speed, the vehicle stalled and shut off without warning. The vehicle was pulled over to the side of the road and was restarted after a few minutes. The dealer was unable to diagnose the failure. The failure recurred several times and was taken to a different dealer. The dealer replaced the fuel pump, but the failure recurred. The manufacturer was notified, but did not offer assistance. The failure was not remedied. The failure mileage was approximately 79,000.
I was diving down hwy 70 going to pick up my first delivery for the day when, I'm not sure how but the key came out of the on postion and fell out on floor, scared I was going to crash I hurriedly reached down and put it back in and noticed the security light had came on and within minutes it lost all power and shut off, luckily I AM a good driver and didn't crash but manage to get off road safely. I'm so glad worse didn't happen. Now I have no car and probably lost all 3 jobs I had.
