Window regulator on front passenger side went out three weeks after purchase.
Both headlamps fell off within one month of purchase.
Tail lamps are coming off. You can see the taillamps separating from the car. Moisture gets inside.
Drive Side Information Center shorted three months after purchase.
Door clips have broken off so the door panels just hang. When you close the door the whole door rattles. This has happened to three of the four doors.
Air Conditioner compressor and orifice tube had to be replaced.
Driver side control center for the windows and door lock fell into the door. Left front window regulator and switch shorted out.
Oil pan and valve cover gaskets had to be replaced.
The audio steering wheel controls have shorted out. If I turn the steering wheel to the left the radio blares full blast. I cannot control the radio with the steering wheel controls. My extended warranty has expired so I will have to fix this on my own.
Seat belt reminder light comes on and stays on while I'm driving even though I have my seat belt on.
I cannot use the accessory power outlet that is located on the passenger side, near the floor. I cannot use my cell phone charger or my car vacuum in that outlet.
Interior light on the drive side door has fallen off. I didn't realize it was loose until I closed the door one day and it got crushed.
I have just about 60,000 miles on my car and I can tell that my transmission will be going out pretty soon.
This car is falling apart from the inside out. There are many more things wrong that I just can't think of. There are a lot of these similar problems reported to the National Highway Traffic Safety Administration and I am surprised that Pontiac hasn't done a voluntary recall.
My 1998 GTP transmission, suspension, creeking noise in the dashboard, and need overhaul of supercharger.
I drove this car in a normal everyday fashion. No racing or whatever and still have to spend lots of money with only 93,xxx miles on it.
I'm trading the car to a foreign car. Good-bye apple pie cars.
I have the same problems with my 99 GTP. I am currently at 110K, which is good for me, but bad for the car. I am currently plagued with a problem on both the front and rear window regulators on my 4 door. And when I took the door panels off I found out about the nylon tree style clips that need replacing at $4 a piece. Now the problems going to cost me an additional $50 a door in clips, and whatever I can get the regulators for. The gasket around my air intake for the supercharger is shot, and spitting oil, which then smokes off... The lights both fell off at a young age, but the tail lights will need replacing as they are falling apart also. The GTP sign from my driver side has fallen off, and I don't know where to get a replacement for that. I have had various problems with my interior including the radio cutting out, and various problems with the mirror controls, light controls, and steering wheel control.
I have a 1998 GTP and I have only had one problem with it. That was the fuel pump. It had to be replaced. I have 92000 miles on the car with a smaller supercharger pulley on it for more hp. I beat the car and race it whenever I get the chance, it is one of the funner cars that I have owned. Sorry to hear about all of the problems you have had with your car I think that you must have gotten one of the very few bad ones.
I recently got rid of my GTP a couple months ago and I have never been happier. I bought the P.O.S. in 2001 and ever since then I had problem after problem. It all started with both the headlight cover falling off. Of course they didn't both fall off at the same time, there were a couple months in between the times. The next problem I had was with the fuel pump resistor. That went out while I was driving the car. That was a dealer only part that cost a pretty penny. The driver side window switch motor went out. I replaced that part and then it went out again after a couple months. The transmission started slipping around 75,000 miles. The power steering pump went out while I was driving. Right before I got rid of the car I found a crack in the radiator. It felt good to get rid of that car. Car looks nice, but falls apart quickly.
I have a beautiful Black GTP, and I Love It. I have had to put it into the shop one time to fix a low coolant sensor. Other than that, it has been wonderful. It has 140,000 miles and its still running great. I get many comments on it all the time. Most of the previous comments seemed very negative, but I have only had a good experience with my car.
I have a 1997 Grand Prix GTP... and there's nothing wrong with it other than the air condition whines once in awhile.. still haven't figured out why. It's a great overall car.
I have a 1998 gtp with 112000 miles on it with no serious problems except pulley noise from the drive belt. It's a beautiful, fast car that rides great and handles corners like it was on rails. great car for the money!
I have a 1998 Grand Prix GTP and I do not know why you all had so much trouble, as mine runs great!
I own 98 GTP, and it is just a great car. There are 140k miles on it and still runs the same as the first time I pushed the gas, with great torque.
I put on 17" rims and it looks awesome. I treat it as if it was a Ferrari, and I receive offers every time I drive it.
I repaired the trans just because I race it very often. Besides that, everything is working fine. I'm not thinking of replacing it soon.
I recently purchased a 1998 Grand Prix GTP with about 119,000 miles on it. I wanted a good dependable car to give my son on his birthday this coming spring. I figured I'd "drive the bugs out of it" over the next few months. I had the same problem with the radio controls on the steering wheel., only my volume went down instead of up on left turns. I simply went to an auto salvage yard and got the part from a wrecked vehicle. If you grab the unit (all the individual units come out, volume, seek etc.) and gently pull it out, you won't be as likely to damage the press in connector when removing it. It takes a little patience to get the wires reconnected, due to the shortness of them, but once it's back on I have had no further problem. I also changed the rotors and brake pads as a precautionary measure (and painted the calipers white with 1800 degree paint, just for looks). The parts aren't too much, especially if you are a G.M. employee, or have a relative who can get the employee discount. I have only put about 1,000 miles on the car so far, but having gone thru it with a "fine toothed comb", I have not found any major problems. There was a howling noise in the rear end when I bought it. Turned out to be bad tires. The front and rear were 2 different brands and I went ahead and bought 4 used ones with less than 100 miles on them off a great local site called www.craigslist.com for $225. Problem solved. Dealer did rebuild the supercharger prior to my purchase, and paid $700. Seems a bit steep to me. Part was a gear that was apparently made of a nylon type material, not the best thing to use in a high speed component. If you do change pulley size on the supercharger unit, it is recommended that you add a transmission cooler as well. One other problem I fixed had to do with the TCS light staying on in the car. A mechanic ran a computer test on the car and told me it was the wheel speed sensor unit on the drivers side front wheel. He also told me it was part of the wheel hub assembly and would require replacement of the whole unit, around $240 with parts and labor! Not true. I picked up the short wire harness at the salvage yard for $5 and installed it myself in about 15 minutes. Problem solved, huge amount of money saved. This forum is an excellent way for back yard mechanics to save each other lots of cash and headaches. Keep up the helpful work!
<Supercharger part was a gear that was apparently made of a nylon type material>? hmmmmm.
Might explain why my 99 GTP (98k+ miles) has had a rumbling sound at stop or idle? Or, it is a bearing? I had the tension belt and two tensioners replaced this past weekend.
I feel bad for you guys, I have a 2000 gtp, with minimal problems, I have 100+ miles, and I had to replace the passenger window switch, and my steering wheel controls are slowly dieing, but that's expected at around 100,000 miles. I have 19" wheels, computer upgrade, pulley upgrade, intake, full exhaust, and I run this car to death, never had any problems. Sorry for those of you with bad experiences.
I have a 1998 Pontiac Grand Prix GTP, I had similar issues, but over the years I dealt with it, because the parts are cheap, and easy to find. The car has 146,000 miles on her now and thinking about replacing the radiator because at times the car runs hot and smell like it too.
P.S. The supercharger oil must be check at least twice a year. It is not a part of 3000 mile oil change. The noise comes from there...
I bought a 1998 grand prix gtp off one of my good friends. I know it had been taken care of that's why I got it off of her. I had it three months then it started falling apart.. I have got so much money in this car it isnt funny... its looks great.. but I just can't depend on it.. it is so hard to pay for it and try to keep it going I don't know what to do.. but cry' Guess what? back in shop for transmission its a piece of junk!!!!!
still crying
My 2001 GTP has 75k on it. I drive it very easy. Transmission gave out at 43K. Headlights bounce while driving down the road. Notice many other GPs doing the same. Heater fan only blows on 5. Have read that this is a "resistor" or harness problem. Fuel gauge went wacky a couple of months ago and reads full at random, bounces all over the place, can't trust it. Now the car is sitting in a lot because it shuddered and died last night and won't start now. This reminded me that my 1st GTP (1996) had the same thing happen at about the same mileage and it was a "resistor in the fuel pump". I seem to recall the same problem with the gas gauge, also. What bothers me is that these same problems occur over and over too many people and it's been happening for 10 model years now! You would think that GM would have realized a long time ago that they have a DESIGN problem with their fuel pumps and fixed it. Guess it's cheaper to stay with poorly designed parts that will make it past warranty.
