2007 Pontiac Grand Prix: engine stalls while driving

Filed Apr 4, 2021 · Electrical, Engine · 170,000 miles · AR

I have same problem as others. Have been able to start car sometimes by putting it in neutral. Several years ago I left the car with our son to see if he could figure out the problem because my wife quit driving the car after being stranded a few times. When using blinkers the high beam would come on. It has a roaring sound like a wheel bearing going out.the key fob doesn't work. I've been told the bcm body control module could be causing problems. Had estimate of $500 to replace and program new bcm.. We have towed car home after going to store. I used to drive otr so we got a second vehicle to drive. After reading other posts on this car 4/4/2021 I don't think I want to put more money into it. Especially when I've read gm techs can't fix the problems.. Once the vacuum line to brake booster came off when my wife was going down hill. I put the line back on, it hasn't done that again. We have not driven the car out of town for fear of it breaking down. And shops not being able to tell us what is wrong with it.. I tied a cable on trunk release so I can open trunk. . We did love the car when it was running. Has 193,000k at this time. Has stalled/quit on city streets. And we quit driving it on highway.

My "reduced engine power" light came on. Used a snap on $5000 scanner. Codes say gas pedal sensor. Changed that problem still exists. Cleaned throttle case. Car stalls and I have to press gas pedal to the floor to get it to 20 miles an hour. There are so many blogs on this problem its unbelievable. I just had the recalls fixed on the ignition and head lights. Now this issue. Please help. Im single, homeless, and unemployed. This is the last thing I need right now.

When I start my car, it will stall out, not turn over or it will idle for a few seconds, then immediately shut off. I mean shut the whole car down so nothing electrical can work at which point my key will be stuck in the ignition and I cannot get it out. I am able to restart the car normally, however the steering wheel vibrates along with the body of my car while in motion and while parked. While making a left turn through a four way intersection, I lost control of my power steering and the wheel was stuck at first and then swung all the way back which spun my car around. This car has had 1 owner before me and I have kept up with all of my oil changes and tune ups. In september of 2018, I had a similar issue with the vibrating and was told that a cylinder was misfiring and that I needed a tune up. I spent $587 on these repairs. My vehicle was at 98,890 miles. It is may 2019 about 9 months later my vehicle is at 108,630 miles and I am having the same and additional issues not even 10,000 miles more. I have documentation from the mechanic from my cylinder repairs that I have requested to be faxed over to me.

Crank shafts position sensor causes the engine to shut off while driving down the road. Resulting in the loss of power steering, and power brakes. This occurs at all speeds from stop and go traffic at less than 5 MPH to highway speeds of 70 MPH +. This is a very dangerous issue. Adding the recall piece to the key did nothing to remedy the issue. This has been occurring for 2 years now.

After traveling about 150 miles from macon, ga, in the morning of the 16th, the car shut down on I-75 in heavy traffic going 75 MPH in the passing lane. We had no engine power, power steering or brakes, but managed to coast to the shoulder. I was able to restart the car after a few minutes only to have it stall out after 10 or 15 miles. The only warning was 2 chimes from the car before total shut down. We did have flasher lights and were able to restart the car each time. This happened about 6 or 8 times. We stopped at several auto parts places to see if we could find out what the problem was, but no luck. We were able to get to a chevrolet dealer in ashburn, ga (parker chevrolet). They were not able to diagnose the problem, or didn't want to deal with it. Poor service! They said everything was okay! Just 2 miles from the dealership, it stalled again. We managed to get to gainesville, fl where the closest chevrolet dealer was located. We talked to [xxx] from gainesville automotive chevrolet who was a calming voice after our experience. She gave us a hotel recommendation for the night and said to bring the car in at 7 am the following morning. She was great, and so was the entire staff! They got right to work on the car the next day at 7 am. After about at hour, the service manager informed us they found the problem, but it would require a new computer at a cost of $940 and could be back on the road by noon. We were back on the road by 12:30. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

I, the owner of a 2007 grand prix sedan, operating said vehicle on a neighborhood street at the speed of 20 MPH experienced stalled vehicle. Was unable to steer, brake, and realized the vehicle had stalled while driving. Applied emergency brake in order to come to a controlled stop to prevent crashing into traffic. Turned the ignition key completely off, place vehicle in park, and attempted to restart vehicle. Electric ignition switch continued to try to start the vehicle, taking 3 attempts before the ignition switch allowed vehicle to start. Gm must address this or it will cost more than just parts, it will do it again and no one can say where my family and I may experience this again. It was a terrifying experience to have no control while car is in motion with passengers in the vehicle.

I was on my way to work when my car just stopped moving. I was barely able to get off of the road without being hit by the car behind me. I had it towed to the chevrolet dealership. The car was still under warranty so the transmission was replaced. However, less than 10,000 miles later the 'new' transmission is slipping badly. I can't afford the $2800 plus labor to have the transmission replaced again so I guess I will just have to hope that I don't get ran over when the transmission goes out again. After researching this car I have found that transmission failure is common. Why is this not considered a danger not only to the people in the car but to the other people on the road that the car could stall in front of?
