Selected complaints filed with NHTSA by 2000 Pontiac Grand Prix owners, lightly cleaned up (personal details are redacted by NHTSA).
There are many safety concerns on this vehicle. The first concern is the smoke that comes from under the hood because of the oil leaking on the engine while in motion. To the point I have had to use a hose to cool down the motor. Oil poured out with the water. I have had the prior recalls done and still had leaking after the so called recall was done in 2010. I was told by castle Pontiac (north riverside, il) there was no further repairs they could offer. Even though I showed them the oil continuing to leak after the so called recall was completed. The second concern is the head lamp assembly that is foggy looking causing the vehicle to have poor lighting. The next concern is the suspension that is literally falling apart. I have also had to have the head gasket changed on this vehicle and the transmission had to be rebuilt. …
While driving this vehicle down the road at 55mph, the vehicle will just cut off for no reason, thereby I lose control of ll the vehicle safety componets,having to try and get out of traffic. This happens to a lot of GM vehicle made in this vehicle year. There are many on the internet with the same vehicle defect. This is clearly a GM vehicle defect. This vehicle needs to be recall as a public safety hazzard. Mygm reference number is ( 8-3665783770). So please do the public a service and have this vehicle recall , because this problem is a public safety hazzard. No one mechanic seen to be able to find the problem. This happens after they say my vehicle, spent lots of money ,but no one seems to know what causes this problem, including GM.
Transmission failure at 180K miles. Car will not shift on it own I have to force car into gear by speeding up hearing transmission whine and then letting off the gas pedal so transmission shifts gears. This is on all road conditions. So many complaints have been made why has GM not issued a recall on this matter.
I own a 2000 Pontiac Grand Prix gt about 2yrs. Ago my transmission failed on me. My problem was diagnosed by a ase certified master mechanic. I wrote a letter to GM about this problem,which wasn't my only GM transmission I have had replaced within a 5 year time frame .I also had to replace one in a 1990 Chevy cavalier z24 that was only about 9 years old at the time and I also had to replace the fuel injectors on that as well but that is a whole other story. I called dealerships to get the proper address of where I could send my letter of dissatisfaction with GM, and it was completely ignored!I didn't ask GM to pay for the whole transmission replacement,just to meet me half way and help a regular guy get to and from work with a dependable vehicle,take care of his family and not be hit with a 2200.00 bill that I am still paying on because I had to put it on a credit card and also get …
There have been more than I can count on both hands to the incidents that this care has stalled. It happens unexpectedly and I never know when it is going to happen, but it always seems to happen when I am in the middle of traffic. So, I have to pull over and try and start the car. Which it will start then sputter and stall and die. It has had a new computer, 2 new fuel pumps, fuel resistor, fuel relay switches, starter, supercharger, 2 fuse boxes which are a discontinued part that has to come from an auto wrecker, and recently a wire that was frayed behind the fuse box that had something to do with the fuel system. All this has been done within the last 10 months since we purchased the car on payments on June 1, 2009. Needless to say I am not sure as of this last repair if it has corrected the problem. …
2000 Pontiac Grand Prix gtp has 42,000 miles. We purchased this vehicle new in January of 2000. No sign of transmission failure. Going from a stop loud clanking noise, car jerked 3 or 4 times. 5 minutes later after another stop sign the car did the same thing again. I stopped to a repair station, when I put the car in park it makes an awful grinding noise while idling. The service technician took the car for a drive and said to get it to a GM dealer because the transmission is going. I was told this should not have happened on a car that only has 42,000 miles on it. As I am looking through the consumer affairs complaint data base I am seeing 9 complaints that are quite similar. How many complaints does it take till this transmission problem is recalled? I paid $27,000.00 for my car 3 1/2 years ago and should not have to put $2,000.00 into it already. …
The vehicle has had a problem with the transmission slipping off and on for about a year. Aamco couldn't detect a problem without a check engine light. The light came on in February 2005. The vehicle needed a sensor replaced and there was a error on the transmission also. A complete fluid replacement was done and a conditioner added hoping that this would cure the problem. On June 1 the light came on and the slipping occurred again. It lost merging power on the baltimore beltway and I brought it into aamco for an analysis. They concluded that the torque converter is stuck as well as some additional item. The car is a 2000 Pontiac Grand Prix with 83,000 miles on it. I believe that the power train warranty only covers the vehicle for 80,000 miles. …
The transmission in my 2000 Pontiac Grand Prix started shifting funny then it would shift fine after shutting it off and restarting after this happening a few times I took it to a trans shop and they informed me that this a common problem on GM cars and that the repair would be $600-$700 the car only has 60,000 miles.after talking to a person from GM he admited that they had a bad supplier of parts from 1998-2000 and that if it was under warranty they would have fixed it for free.well its not under warranty and im stuck with a $600+ bill to fix a problem they where aware of.the guy at the trans shop says he sees about 3-4 of these a week.also if you do any searches and reading on the 4t65e trans you will find alot of people complaining of the same thing.to fix this trans they pull it almost apart and put new pressure solenoids in it.
I own a 2000 Pontiac gran Prix gt. Everytime I drive it, the service engine light comes on and the transmission shifts very "hard". This only can be corrected if I pull off the side of the road (which can be very dangerous) and wait several minutes and restart the car. When this happens the RPM's starts to "rev" up and down constantly whether while driving or setting while in park. I have come close to several wrecks when this happens, especially when the roads are wet. Before you know it you apply the breaks enough to slow down for the car in front of you and then the RPM "rev" up and you almost hit the car in front of you in the rear. I have read several similar reports and I really don't understand with all the complaints this cannot be recalled to fix this.
