Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Grand Prix

  • 60,000 miles


Oil leakage from valve covers, transmission failure, hub assembly failure, traction system failure. Problems with only 60,000 miles GM will not acknowledge responsibility or assist in paying for repairs. Found many similar complaints. Should not have these problems with low mileage on this vehicle which was purchased new and well maintained. Told by certified mechanics that these problems should not have happened.

Pontiac Grand Prix 2001: Was hit by another car in the left rear while car was at red stop light waiting for green light, spinned, went on to "automatic" drive and hit fire hydrant on the right side fender. The impact may have been too great to cause the vehicle to move passed median and still hit a fire hydrant and stop sign at the intersection. My wife suffered multiple injuries, I.e., broken ribs, neck wounds, organ burst, etc., that killed her at the scene. I have seen a car that went on "crazy spin" after running over a piece of tire on the road. I have been bothered by that incident which happened just a month after my wife's death and began to question the design of front wheel driven cars that go on to "automatic" drive after any disturbance. The other car that hit my wife's car is smaller and it must have been moving over the speed limit of 35 mph to have to cause the Grand Prix to develop that much motion and move at random.. and it must be the mechanism or transmission that triggered it to move. Theorize that the Grand Prix was at stop and brakes applied, car would not move the distance it had if not undergone "automatic". there were previous reports about front wheel cars/engines before they became common. The Grand Prix's on-star did not activate or function, also the air bag did not deploy. It was not physically possible for the Grand Prix to move that much distances if attributed only to other vehicle hitting it. The Grand Prix pro-performance claim was something that have been put together without safety checks. Non-deployment of the air bag also had delayed rescue and the "on star" claim of immediate alert did not work. How safe are the front wheel cars now? I have to read back popular mechanics magazine 1978's back issues to find the article on the front wheel drive cars. I feel that the speed of the other car was not the factor that made the Grand Prix go on random motion. There must be fuel injection mechanism/component problem.

Purchased used 2001 Pontiac Grand Prix in June, 2007. Complained to auto dealer that cars transmission was slipping. They test drove vehicle and stated it was ok. Had vehicle S transmission tested a few months later - it is bad per transmission place. Auto dealer states he will put in tranny at cost of 1,700 to 1800. Transmission center offered to put in tranny for 1200. He will not match the cost nor pay for it. I feel he is partially liable for this as he sold it like that. Please advise me of what legal rights I have as a consumer.

Purchased this car used, it was 2 years old with about 21K miles. Kept up with all maintenance. Dealer extended warranty for 3 months. But did not notify me when the original manufacturers warranty expired so I was unable to extend. Purchased a platinum warranty from aaa. Transmission "blew up" at 48K miles. Had it replaced per warranty w/a used transmission as warranty would not pay for new one. Drove the car for 19 mos and 12K miles and transmission blew up again! dealer said warranty was only good on transmission for 1 year and they are making inquiries as to whether I have to pay for another one even though my contract w/aaa warranty co is good to 8/10/08 or 83,894 miles. Why is my car eating transmissions"?" help!

I bought the car Oct 2003 it had 23000 miles on it and then when it hit 30000 miles that's when trouble started my husband went to check on his brother and turned the car off and was off for 1 hour and went to start the car and it wouldn't stay running took it to the local repair man and he worked on it and nothing $250 dollars later he hauled it the GM dealer in independence ks. Where they said it was the anti theft device had me locked out and the had to replace the module. $480 later. Now when I drive a distance my check engine light comes on and my car acts like it tries to cut out and shifts hard and jerks. And my tract off light stays on now all the time. My last Grand Prix had 160000 miles on it before it started acting up. My local repair man said that I need to replace the brain module and all my problems well stop. And now when it rains my car feel up with water on the passenger side floor board 2 inches right now so if there is a recall on this car it needs to be the whole car. Right now the car has 51000 miles.

Hello, I purchased a 2001 Pontiac gran prix GT in June of 2004, I paid cash for the car and have been having problems with the transmission since the first week I bought it. I feel I have been getting the run around on getting it fixed properly. I have had to fight my wat through the dealer (laura Buick Pontiac GMC) in collinsville, il. In getting this fixed. They did finally replace the transmission in December of 2004. At this time then the car was hit on their lot and had to get that fixed and had to argue with them over that repair. They did repair it weeks later. I took the car back to laura Buick of collinsville to have the transmission looked at again due to it was having the same problems at this time they stated to me that they drove the car and found nothing wrong with the transmission itself, but did here some wining making aleft turn and that it was the power steering rack needed to be repaired and the cost of that would be $862, at this time I don, T have the money to get the car fixed so I went to pick up my car and they told me I had to pay $65 to have my car released to me. I don, T feel I owe this money because I was told that he test drove the car so before anything extra was performed I should have been notified of any additional fees. I have not been satified with this purchase since I bought the car and I can go into deeper detail if needed. All I, M asking for is to have the satifaction of my car being repaired-- they got what they wanted and that was the satifaction of selling the car to someone like me. Please help! an unsatisfied customer.

My 2001 Pontiac Grand Prix gtp has had a grinding noise since 8/31/04. On 9/1/04 it would not go into reverse last night. I took to the dealer and they found the transmission shut. Theyre quoting approximately $2,700 to put in a new transmission. I cannot believe that this would happen to a 3-year old car with 45,000 miles on it!
