Grand Prix

  • 84,000 miles
The contact owns a 2004 Pontiac Grand Prix. The contact stated that while driving at various speeds, the ABS would engage abnormally. The vehicle was taken to a dealer who diagnosed that the two front sensor hubs were defective and needed to be replaced. The remedy failed to repair the problem. The vehicle was then taken to a local repair shop who stated that it was probably an electrical short coming from the ABS computer and sensor that was connected to the wheels, and was causing the failure. The manufacturer was made aware of the failure who referred him back to the dealer. The vehicle was not repaired. The VIN was not available. The failure mileage 84,000 and current mileage was 94,000.

When braking and turning the vehicle at slow speeds, ie parking the car in a lot, the ABS will activate. This occurs at least half of the time I make a slow right turn, and has also happened a few times when turning left. I have had the ABS activate even without touching the brake pedal (accelerating while turning from an intersection for example). Dealership has said the problem is in either the ABS sensor or the wiring harness, but the computer was not generating any codes to specify which, so they are so far refusing to fix anything.

I purchased a 2004 Pontiac gran dprix GT2 in June of that same year. One week later the repairs began. The most scary occurring on the date mentioned on this complaint, May 26, 2005, eleven months after I purchased the vehicle. My car died while driving 65 mph on the highway with my three small children in the back seat. The car had no power whatsoever, no steering, no gas, no lights, nothing. I thank god we are alive. The mechanics at the dealership diagnosed the problem as a faulty ignition switch. After this incident I rented a car at my own expense for eight weeks. We did not step foot in the vehicle for that period of time. For financial reasons I slowly began driving my car again. There were repairs before that event as well as afterwards. These include the brain, transmission, brakes, axle, wheel bearings, steering, sunroof, fuel injectors, and safety belts.

Grand Prix 6-cyl

  • Automatic transmission
  • 47,000 miles
On 8/20/05, the traction and stability control lights came on while driving on the interstate with cruise control on. After stopping the car, turning it off, and turning it back on, the lights went out. Between that time and 8/23/05, this occurred 5 more time. On 8/23/05, the brakes locked up on the vehicle while driving on the interstate using cruise control. I took it to the dealer. They diagnosed it as codes C0187 & C0197, and replaced a faulty yaw sensor. I took it back to the dealership on 10/19/05 with the same problem, after occurring 3 times within a 2 day period. The dealership drove it and it occurred twice, but they cannot determine what is causing the problem. They have now had the car for 6 days. The dealership is jim hudson, and their phone # is 803-783-0110.

Grand Prix 6-cyl

  • Automatic transmission
  • 29,000 miles
I was involved in a car accident on 7/5/05. I attempted to brake in order to avoid hitting a car. I slammed on the brakes but my car just kept going and going. It must have continued for about 50 feet. I feel if my brakes would have worked I wouldn't have hit the car. It's like my brakes only partly worked. I just bought the car 3 months ago and was not aware of the recall on the brake system. I will look into that. Another thing, I was told that since no one was in the passenger seat, the air bag should not have deployed. The passenger airbag engaged and broke my windshield.

Grand Prix

  • 14,075 miles
My complaint is not specifically about a car - it is monr about the company that rented me the car. Monday, Aug 2, I rented a 2004 Pontiac Grand Prix from avis at the baltimore Washington international (bwi) airport. While driving to work on the northbound fairfax county parkway on the morning of Aug 3 (normal weather condidtions), I stepped on the brakes (somewhat hard). The wheels on the car immediately locked up and the car began to spin towards the right. The car did a full 180 turn through 2 lanes of traffic landing on the shoulder, w fraction of an inch away from the guardrail. I was extremely lucky. I did not hit another car, or get hit by a car or even smash into the guardrail. No damage was done to the car and I was not injured. When I returned the car to avis (because I no longer felt safe driving it) the emplyee behind the counter mentioned something about a brake recall and wondered if it was that make and model. I found the recall via your website this morning. Apparently my accident is the exact consequense of not getting the recall fixed. I'm appalled that avis rented me a car that they knew had problems and was being recalled. I want to make sure this doesn't happen to anyone else. I'm sure that avis has hundreds of 2004 Pontiac Grand Prix's in their fleet, so this issue needs to be remedied immediately. I don't really know whose attention I should bring this too, but I cannot imagine anyone else encountering this incident and being as lucky as I was to walk away unscathed. I'd greatly appreciate any assistance you can give me in this matter.
