I have a 2003 pontiac gran am gt ram air four door sedan. Several weeks we experienced a problem where the car would suddenly accelerate without the gas pedal being depressed, the car would continue to accelerate until the gas pedal was quickly depressed or I hit the brakes. I took the car to my repair shop and they replaced a cable. The problem ended than a few weeks later reappeared. I took the car to a pontiac dealer (adams/annapolis) and they cleaned out some connections, but the problem returned shortly after this. I returned the car to adams and they replace the computer. This appeared to end the problem but I experienced the same problem once yesterday but it has not reoccurred since.

Numerous complaints regarding a 1997 pontiac grand am for repairs/ replacements of parts. Door windows do not function, motor has had to be replaced by former owner, we have repaired motors on door windows several times on our own, windows would not go up and down at all, cost to repair at mechanics was over 400 and was done by first owner at least once. Car service engine light comes on, had to replace entire computer system and now same problem is happening again, car idles horribly, sounds like it will be blowing up, and check engine light comes on. Prior to the replacement of the computer car frequently stalled out while driving in mid turn or while going forward, and car frequently was difficult to start, eventually needing to be towed to a repair facility who had to replace entire computer. Car has wheel bearings that make a lot of noise, sounds like wheel is going to fall off. Car has accelerated all on its own without the driver stepping on gas pedal or doing anything at all with accelerator, car randomly decides by itself to lunge forward and try to drive itself. This stopped briefly after the computer was replaced and is now happening again.

Cause of sudden acceleration: I had a pontiac grand am 1992 and the vehicle did accelerate by itself. The cause is a little piece of rubber that slides off the pressure valve, causing the vehicle to maintain an average of 30m/ph, regardless of which gear the car is in. The main reason the plastic slides off is if the car has been floored. In other words, if you drive too fast and press the gas too hard, then the rubber will slowly slip off, causing loss of pressure and automatic acceleration. Must get problem fixed or get rid of car. I have started a class action suit against gm for safety violation and the denial of having the vehicle repaired and death. Vehicle accelerated causing death to pedestrian.
