The key had started getting stuck in the ignition, one day it just did not come out. Once the ignition tumbler was removed there was a long crack down the side of the housing which was causing the keys to loosen and so the key was not turning in sync and got stuck. The key broke off in the ignition stuck on accessory until the part came in I would have to unhook the battery every time I left my car for long periods so the battery would not drain power. One time I was driving down the highway and the cable came off because of being loosened from multiple removal. I lost all power driving at 70mph I did not panic I simply pulled over and waited for a jump start however I could see this resulting in a bad accident.

Was driving at 45 mph one night and the headlight, which were set to auto, suddenly went out. Was able to continue driving using the high beams. Later that evening the lights resumed working. Didn't happen again until the following month. Happened about 3 times but now low beams are not working at all. Replace the bulbs, switch and module with no luck. Checked all fuses which are fine. Now I have no working low beams and am driving the car using high beams only. I worry that high beams will stop working while driving which could be very dangerous. Very concerned that I have seen multiple complaints on the internet, some resulting in fires, with no resolution. Shouldn't this be addressed by the manufacture?

2007 Pontiac Grand Prix VIN: [xxx] high beam headlights come on while traveling without cause. October 28, 2014 tonight coming home traveling approx. 25-30 mph on side street low beam lights switched to high beam without driver ever touching turn signal/headlight switch arm on left of steering column. Originally it was noticed during right hand turns when right hand blinker turned on that head lights would change from low beam to high beam. This observation started occurring approximately November 2013. I have read about fires in other vehicles from faulty switches and this concerns me greatly. Is there a recall for this issue so it can be fixed? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I parked my car at work. When I got out of work the car would not start. The low beam lights apparently never shut off. The switches inside the car were all off. I jumped the car and drove home and found that no matter what I did the headlights would not shut off. I went to pull relay 35 and burnt my hand. It was melting and I had to get a pair of pliers to remove it. I have had this relay fail at least 3 times in the past but it never kept the lights on. They would only not turn off. Researching online this seems to be a common problem with people's car catching fire.

The contact owns a 2007 Pontiac Grand Prix. The contact stated that while driving at various speeds, a burning odor emitted inside the vehicle. Approximately 10 minutes after turning the engine off and exiting the vehicle, the contact discovered flames coming from the roof of the vehicle. The fire department was called to the scene. The flames were extinguished by the contact. The vehicle was destroyed. A police report was filed. The vehicle was inspected by the manufacturer. The manufacturer determined that the fire was caused by a faulty radio. The failure mileage was 70,000.

My 2007 Grand Prix lower lights just cut off while driving with no warning. It's been going on for about a year. I replaced my battery, my alternator and starter is working fine. My high beams did it twice about 8 months ago but haven't happened since. I'm scared to travel at night but I have a brother who can't walk and he lives on the next road from my house and I have to go to his house every night. I have 2 friends that have a Grand Prix, one has a 2006 and the other a 2008. They have the same problem. Our key pads don't work either. Mine stopped about a year after I purchased the car in August of 2007. All these people are not having this issue by coincedent. Please contact me soon.

Over the past 3 years at random occasions the low beams would just turn off in my car while driving. Luckily, the high beams have always worked so I could continue to drive. I researched how to fix the issue, and I ended up replacing the relay to the low beams twice since Oct. 2011. Replacing the relay always seemed to correct the issue. I was always under the impression that it was just a faulty relay. Last night, my wife returned home from dinner and the headlights would not turn off. She called me to ask what she should do. I advised her to either disconnect the battery or remove the relay that has been a problem in the past until I could come home and take a look at it. As she opened the hood she noticed a burning smell. It was dark so she went to grab a flashlight, and upon returning the relay panel was now on fire. Thankfully there was a fire extinguisher nearby for her to extinguish the flames before it got out of hand. Our 3 year old and 8 month old sons had also just gotten out of the car as well. I cringe thinking about what could have happened had my family been driving an extra 10 minutes when this fire began, or if my wife couldn't have returned in time with a fire extinguisher. I have read multiple other reports online of other individuals having the same issues with the low beams shutting off, and several that ended with a fire such as ours did.

Traction control / ABS brakes feel like they well not stop vehicle/ when ABS and traction control lights come on which is probably 90% of the time. About 2 months ago I had the rotors and pads replaced, I thought this would cure the problem only to make matters worse. Thank you

I noticed my car lights would not turn off. I then drove my car less than 5 minutes away to pick up my kids. Upon pulling into the parking lot I let down my window and noticed a burning smell. There were guys around at the time that noticed as well. They then ran to my car asked me to pop my hood and we noticed my fuse box on fire. They where able to unhook it to keep the rest of the car from catching on fire. I have filed a complaint also with GM. I have seen from other complaints that this has happen to many of the Pontiac Grand Prix. I cannot find a recall on this from GM. If I would have had my kids in the car and been driving a longer distance this problem could have possibly caused my whole car to catch on fire and could have resulted in injury or even death.

A couple months ago the low beam headlamps began to randomly and intermittently stop working while the vehicle was in motion. There was no apparent correlation between how long the vehicle had been running and when the lights cut off or how long it would take for them to begin working again. Only hi beams worked consistently. As of this past week, the low beam head lamps are no longer working for any length of time. A local mechanic has been engaged to troubleshoot possible causes. After reading online complaints, he will review the fuse block, relay and connections to the computer to determine where the breakdown occurs. We are in agreement with other comments posted on this site. It is very scary the first time it happens. Fortunately, the 20-year old driver was familiar with that particular curve and had the presence of mind to hit the high beams right away. I'm not confident all drivers would recover so quickly under such circumstances. It only takes a couple seconds to engage the hi beams if it's your vehicle and you know their placement. However, people are likely to fumble and switch from auto to manual for the low beams first before engaging the hi beams. That extra time could cost lives. It is a shame that after all these complaints and fires, there's no recall yet.

Leaving my child's day care provider my husband noticed the headlights were not working. My husband continued to drive home thinking the fuse had blown. He had replaced the fuse about 5 months ago and thought it was strange to have it blown out again so soon. He pulled into the garage and took our daughter inside. He went back to the garage to check it out more in detail and immediately smelled burnt plastic. He then opened the hood and noticed the fuse block was melted where the recent relay was replaced.

I went to work on July 15, 2014, after dropping my daughter off at her grandmothers. I worked for 8 hours and as I was leaving I could not get the car to turn over. My dome light was in the off position & my headlights were in the auto position. I could not figure out why my car was dead. I called my fiancÉ to come jump my car. When he arrived and opened the hood he immediately smelled something burning. He noticed that my fuse box under the hood was warped and when he opened it smoke rolled out and 1 relay switch was so burnt/melted it was black & flakey and had began to melt the other relays around it. My fiancÉ had to have the car towed home. Upon further inspection it has also damaged the wiring harness. I have researched this and I have discovered that many people have been reporting this same problem online for a number of years now. Some vehicles have even had a fire under the hood of their cars. This is a hazard to anyone who drives the vehicle and to those who are around the vehicle if a fire does break out.

My low beam head lights go off intermittently. We have replaced the relay under the hood as well as sensors. This happens almost every time we drive. Clearly its quite a safety issue, they have shut off unexpectedly while driving at a high speed on the interstate in the pitch black of night.

Push button to turn on ac had not been working fro 1 week. Was told it was most likely the relay fuse. Drove car to work without complications. Worked 13 hrs and when I got off work car started without problems. Noticed both the head lights where not working. High beams worked fine and so did the fog lights, but the low beams wouldn't light up. I checked the 'under the hood fuse box'. it looked fine from the outside, but once I opened the lid on the box I saw the problem. The relay fuse had caught fire and melted the fuse next to it causing them to fuse together. The board under them had also melted, along some of the fuse areas next to them. All of the other fuses had sticky burnt plastic on them, along with the inside of the lid.

1) low beam head lights would just turn off without any apparent reason. High beam works ok. 2) when taking the steps to use turn signal handle to signal a left turn, the high beam headlights would turn on. This could be caused by a shorted circuit in the steering column or excessive wear. This incident appear to be connected with the low beam head lights turning off for no apparent reason.

The contact owns a 2007 Pontiac Grand Prix. The contact stated that the vehicle would sporadically stall. The vehicle was taken to an authorized dealer for a diagnosis where the ignition module was replaced under warranty. The failure recurred. The vehicle was taken to an independent mechanic, who also replaced the ignition module but the failure recurred. The manufacturer was notified of the failure. The approximate failure mileage 20,000 and the current mileage was 64900.

I had been having a few problems with the headlights. The would just randomly turn off at night. They only worked when they wanted to. On the morning of October 17th I stopped at the store on my way to school and once I came out of the store (about 10 minutes later) I smelt something burning and noticed smoke was coming from under the hood. When the hood was popped the relay box was completely melted and the wiring harness had a fire starting to ignite. I caught it right after it started. GM claims they know nothing of it and is refusing to cover the costs. After reading many instances on this I would like help in getting something started. There is a serious defect with this vehicle. Thankfully my child was already dropped off at school and no one was hurt. I know GM knows of this issue and doesn't want to take responsibility. My car is still at the dealership and is costing close to $3,000 to have all of these parts replaced. I think GM needs to step up and you are the guys that are going to have to make them take responsibility. I am doing everything in my power to try to get a recall started and to have them pay for their faults. Please help!!!!!

I have had my 2007 Grand Prix for 5 years now and it has about 55,000 miles on it. In November of 2011, I paid century Buick GMC (tampa, fl) to replace the ignition module and crank sensor because my car had died while on my way to work. On October 1, 2012, I brought my car in because it again died while driving to work. At this point, I paid another $550 to replace the ignition module since I did not realize it was the same part from the year before. Then again on Saturday, November 10, 2012, my car died while driving on the highway (70 mph) at night. It was a very upsetting, frustrating and scary situation to be in and I can?T imagine if I had been alone and stranded. When I finally heard from the dealer on Monday, they simply said I needed to replace the crank sensor. When I told him that they supposedly fixed this problem a month ago, he then said they would replace the part for free. Since I was not satisfied with this response to the problem, I asked to see their copy of my file to review it and brought it to their attention that I had already paid to replace these parts a year ago. They seemed to be surprised about this and said they would submit papers for reimbursement. In the end, I was told by the dealer that I must have received two sets of faulty parts. I asked if there could be an underlying problem to cause these parts to go bad and their response was "not that they can see." I then drove away after they said they had fixed the car and I brought it back within two hours because it was not driving correctly. Later that day, I was told they had not replaced the spark plug correctly and that it is now fixed.
