Vehicle was stationary, had been parked approximately 10 minutes. The vehicle caught fire and was a total loss. The cause is unknown, but we believe it has something to due with the recall about Grand Prix's catching fire.

Car has been continually overheating, radiator has been flushed and refilled with fresh coolant and new thermostat was bled. Car is fine while driving over 50mph but overheats when in traffic at a light. Driver back window motor is out, the window goes down but won't go up. The car stopped abruptly while driving and had to pull on the side don't know what happened but it won't start up but the lights come on inside the vehicle. I have had trouble since purchasing this vehicle. GM needs to take this vehicles completely off the road they have stop making them and I can see why they're nothing but money eaters.

R reading some of the complaints that have been submitted, I don't know where to begin or if I have enough characters to express my frustration with my 2006 Pontiac Grand Prix GT supercharged. My recent issue is that the car keeps cutting out and stalling.I took the car to the dealer and spent $110 on a diagnostic after 4 other local mechanics could not duplicate the issue or pinpoint the problem. The result from the dealer's diagnostic was: P0300 multiple misfires; needs 3 coils and ignition module replaced $1090 installed; also has a bearing going out in the super charger and there is a harsh 1-2 shift. I just spent about $1000 getting fuel pump, back wheel bearings, right brake hose, and valve cover gaskets replaced. Rack and pinion had to be tightened although it was replaced twice last year (bad part the first time). I have had power steering pump replaced, water pump replaced, air intake tube/valve replaced. Paid dealer for diagnostic because no codes or indicator lights were on and 4 different mechanics couldn't pinpoint issue. Dealer stated they have up-to-date equipment and code P0300 came up. Car intermittently hesitates to start. Car acts hesitant after car starts after hesitating to start. Interior seats and dashboard has cracked. ABS/traction seems to be failing, car still moves after applying foot on break...slides a little, no immediate stop, even after I have had complete brake work performed (wheel bearings, pads, rotors, hubs, etc.). supercharge switch has been replaced and elbow tube off the motor block (think that is correct, it's an L-shaped small tube). A lot of repairs have been made. The car runs smoothly when necessary repairs are made. Hate to get rid of the car with all the money and care that has been placed into the car. I am not in a postion to purchase a new vehicle but with the miles I don't want to put extensive $. GM won't assist.

2006 Pontiac Grand Prix: Vehicle engine shuts off while driving regardless of the speed you are going example: 10-65mph, steering wheel locks up so you can't pull to the side of the road to avoid crash. A month or so before engine started shutting off my airbag light an tone was appearing and alarming... I've almost been crashed into 4 times by semi's an school buses. This is very serious an dangerous it almost caused my life an I am 7 months pregnant with a 6 year old who has also been in the car with me. I hope this gets resolved I wasn't warned of any recall good thing I started googling an found out that there has been a recall on my ignition/electrical system.

Were traveling and without warning the car stopped running and we were on a very busy highway and barely were able to get off the road and out of traffic area. Had to have the car towed (this expense I think GM should be responsible for now that there is a recall. Also, how can they justify that we wait until October 1st to have their goof-up repaired. At times it is difficult to even get the key in the ignition to start the engine.

Grand Prix

  • 129,500 miles
I was driving home from work and when I turned a corner, the engine cut out. I believe it was from the key flipping to accessory. I've heard that this has caused crashes that have killed people and would like this fixed. This is the first time it happened, but now I'm worried every time I drive it that this is going to happen and I don't feel safe letting my wife drive the car now. Why are the 2006 Pontiac Grand Prix vehicles not part of the recall from GM?

Grand Prix 6-cyl

  • 72,000 miles
Driving on the interstate going about 65 mpg when all of a sudden I lost all engine power and the engine stalled. Check engine light came on and traction control system remained on. Pulled over and shut off the engine. Restarted the engine, lights remained on and was only able to go about 15 mph. Had to drive it very carefully about 10 miles into the next town. No shops were open at that time of night. Had to stay the night and took it into a shop the next morning. Error code said that the mass air flow sensor was bad. Replaced and drove it around for about 5 miles. Seemed to be running ok. Drove not even 60 miles and the same thing happened again. Took it into a sister repair shop and they replaced the other part of the mass air flow sensor. Was able to drive to my destination and back with no real issues. Here it is 7 months later and driving on the interstate again when the same issue happens. Check engine light came on and traction control light came on. Was able to get off the side of the road but this time. I couldn't even get it to drive 3 feet. Sat on the side of the interstate for 2 hours at night waiting for a tow truck to come get me. Got it into a shop the next morning and same issues. Needed a new mass air flow sensor. Replace and picked up but then the engine started getting really hot. Watched the transmission fluid go from 108 to 258 degrees in a matter of minutes. Pulled off the road and watched the fluid bubble out of the overflow. Got the engine to cool down a bit. Started it and drove 4 miles and the same codes came up and the engine did the same thing. Had the car towed back to the shop and was told that the computer needed to be replaced. Did that and it now surges upon start up. The super charger is not registering as being either hooked up or working now. I am being told that there are several issues that could be causing this.
