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.

I have a secondary air issue that we can't seem to get fixed, even with all the parts we have replaced. Also at night every time I use my blinker the high beams come on and won't turn off. The issue is when im driving at night it seems to happen when my blinker clicks back into place.

My low beam head lights are beginning to fail. My driver side headlight no longer turns on and I believe it be the failure of the hood lamp driver module. After replacing all bulbs and checking all fuses. I have concluded it is this relay that is causing my daytime running lights to fail. There is documentation that this is a known failure but my car is not showing up on the recall list.

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.

The turn signal stalk that is on the left of the steering wheel is defective. When the vehicle is in motion on a street or highway the brights will illuminate randomly blinding other drivers. Additionally, when making a turn and using the turn signal the brights will also turn on when the blinker turns off blinding incoming drivers. This happens every day and on every trip. There has been lots of research completed and there are several other owners of Grand Prix that experience this same problem. The following is a link to youtube where a driver explains his issue and how to replace the turn signal stalk. Https://youtu.be/afaneq-P6Y8 attached is the exact piece that needs to be replaced. I'd be willing to submit a video of the danger this causes if requested. Thank you.

The problem started with "starting disabled due to theft system". upon further investigation I got body codes B3055 and B2960. Upon further investigation I found online this to be a real problem for a lot of people due to the PK3 sensor in the ignition. The problem happened when the battery had died. I jumped started the car as per the manual instructs, drove into town "1 mile from home" left it running the 20 min I was there come home and parked it. Next morning it wouldn't start and the info screen said starting disabled due to the ft mode. Everything oint to a faulty ignition and PK3 sensor in ignition switch not allowing it to read the ECM.

In May 2017 my low beams decided to turn on and off and now they will not come on at all. Also the interior lights have always had problems they have never fully turned on and on top of all of that now my license plate tag light is now longer working. I have changed all of the bulbs and still thing is helping. I don't know much about cars.

When using my turn signal (primarily/ consistently when signaling a right hand turn) my bright lights come on and it is quite difficult to get them to turn off. Occurs occasionally when signaling a left hand turn. This happens when moving or stationary.

While driving, especially when the temp is under 40 degrees. I randomly get error with traction control off and reduced engine power. I have trouble accelerating and keeping speed. Which has been very dangerous to get to a safe spot on the expressway to pull off, when my speed suddenly changes. This has been happening for the last 3 years during the cold months and I have got items cleaned and sensors changed to no end.

My daughters car caught fire while sitting in the driveway. All the front end is burnt. Never received a recall notice

- Prairie City, IL, USA

Reference recall 14V755 Nov 25, 2014, I experienced this problem in February 2014 while driving home at night on a back road with little traffic. I was going 45 mph and suddenly pitch black. I thought quickly thought to hit my high beams. After spending money, replaced the relay and the following July it completely melted down, burning up my fuse box and several wires in the harness while parked in my driveway without keys in it. I happened to walk out and smelled it burning. I was able to remove the positive battery terminal. Clearly it was the (hdm) headlight relay stated in this recall. (photo attached).I've spent about $1500 in repairs. There are many blogs with the same problem and burned up a lot worse than mine. It seems to be a regular problem ending with fires in the fuse box.

While driving, the car suddenly loses power. "starting disabled due to electronic throttle control" message shows, then reduced power message. This happens while going full speed (interstate) stopped at redlight, reduced speed making a turn, or in park idling. First dealer said nothing wrong that they could find. Second said to replace throttle body and brake switch. Both of these were replaced and it still will stop. Called support, and all they would say is to take it for diagnostics, even though it's been done. Twice.

The ignition switch failed on 12/24/2015 while I was driving on the East bound I-80 in California. I was not able to use the brakes or steering and rear ended the truck in front of me at about 40 miles per hour. The air bags did not deploy and I was bale to start the car and drive off the highway. Surprisingly I had the ignition switch recall for my keys mailed to me in August of 2015 and had the Cadillac dealer in reno nv modify my key and key ring on 10/31/2015. But I don't think the modification was ever performed since the ignition switch failed two months later....updated 02/02/16......updated 05-10-16...updated 07/13/16 updated 09/19/2017
