Pontiac Grand Prix adaptive cruise problems

Filed Mar 1, 2021 · Acceleration, Lights · 218,000 miles · KS

My power steering went out and when you try to go over 40 the car lunges forward and has a hard time shifting and will continue while in cruise control. I already had work done on the fuel line cause the line was clogged and the vehicle would lunge forward cause the fuel wasn't getting pushed through. My power steering went out after my boyfriend parked it. He only noticed it when he tried driving away and he couldn't turn the wheel like usual. The cruise control does its thing while in motion. Also the headlamps! The brights stay on, you have to hold the dimmer switch back to get the brights to turn off but if you let go of the switch they turn on and flash people. It only turns off when turning left. The AC compressor blew too. I had bought the vehicle 3 years ago during the winter so it was blowing cold air, but when summer hit is when I noticed it was only blowing air from outside into the cab. The heater works, but the AC doesn't. My boyfriend was driving home recently and couldn't move the steering wheel and almost had a head on collision because of the power steering. The power steering happened in town at his place of work and had to drive on the highway to come home. The cruise happens on the highway. The headlamps is a constant thing, we pulled the fuse that controls the brights and the dims worked just fine, but it's hard to drive at night without brights.

On the 10th of june in 2016 driving down the freeway at 65 MPH with the cruise control engaged, I noticed a white colored smoke coming from the car. In the process of pulling over to the shoulder of the freeway the engine stopped and the smoke continued. Popped the hood and saw a fire on the middle/ frontfront of the motor. The fore was coming from the cover on the top of motor.

This is not the first time this happened we have already fixed this problem 3 times witch the switch cost us 210.00 dollars to have replaced and that is just the part. I will be driving at night and my lights just turn off and never come back on!!! I have almost been in a wreck due to this problem so I believe someone needs to do some research on the pontiac control switch that operates lights blinkers cruise control.

I almost crashed more than once because the vehicle accelerates at full throttle on it's own. Persistent issue. When driving on the express way with the cruise control engaged, the vehicle abruptly accelerates at full throttle, rpms shoot to the red line, and at times the cruise cancels then resumes (at full throttle) on its own erratically and repeatedly within a duration of less than a couple of seconds. This happens at 70 MPH and all other speeds even at 25 MPH. Almost crashed so many times. When that happens, the speedometer reports random vehicles speed. I have sent an email to gm through their complaint section at pontiac.com with no feedback. Dealer did a courtesy dtc check with no luck. My manufacturer warranty just expired, and I'm not willing to pay the dealer to fix gm's design problem at my expense.

I have a 1998 pontiac grand prix gtp that caught fire while driving yesterday, 12/6/07. I had noticed nothing odd other than on the evening of 12/5/07, my cruise control cut-out on me twice while driving home, which I just thought of as odd. 12 hours later, I was driving to work and the car started stuttering. I then lost all power and pulled to the side of the road, as I looked up after popping the hood, I noticed flames on the passenger side of the car. After a few minutes, local fire crews were onsite to put the fire out. The whole engine compartment melted and the car is a total loss. I don't know what caused this, but am reading reports of 1999-2002 supercharged gtp's having this same problem, but wanted the federal safety agency to be aware of this occurring in a 1998 vehicle. The car is totaled and I am quite frustrated. I never thought this would occur in a million years.

I just purchased my 2000 pontiac grand prix this past january and as I happened to be driving it home from a navy event in front of my husband (thank goodness). He pulled up along side of me on his motorcycle and let me know that I had no brake lights. Cruise control also stopped working before this, but I am assuming this all happened at the same time. He is an electronics technician and has spent hours trying to figure out what the heck is wrong. Tomorrow I am going to go ahead and call the dealership and have them look at it. I also have surging with light acceleration or at highway speeds with no diagnostics trouble codes. Both of these started at the same time, but he knows they are unrelated.
