This vehicle keeps blowing the fuse for front park lights and tail lights. Without lights, cant drive vehicle at night or low light, inclement weather conditions. Initial investigation/troubleshooting leads to faulty body control module. The body control module provides ground circuit for multiple electrical functions on vehicle. This problem could result in vehicle wiring harness overloading and catching fire. Problem needs to be addressed with manufacturer. This fault can occur while driving or stationary. Fault occurs simply by turning ignition switch to on position and/or activating the multi-function switch to activate headlights and the fuse blows immediately. Simply replacing the fuse does not fix the problem. The vehicle should be diagnosed by gm dealer to validate proper

Upon starting of the car under normal conditions, noticed a slight burnt electrical smell, after inspection of the engine compartment, I did not notice any smoke or obvious signs, and the smell went away, this happened twice while out shopping at various places. On the final leg of the trip on the way home, I noticed the smell becoming more apparent, and the smell was noticeable at traffic light stops. Once home, I once again inspected the compartment, and noticed a melted spot on the top of the fuse box, after opening, the low beam relay was burnt beyond recognition and fused to the wiper relay. In order to use headlights, I now have to replace the whole fuse box due to the burnt spot in the cover and the fuse box. See attached pictures. I could not attach the picture of plastic dust

2008 Pontiac grand prix lost total power to the car. Discovered that the ignition module had gone bad. *mw the consumer stated it wasn't until after the repair shop replaced the ignition module and did a maintenance check ride, they discovered the source of the ignition module failing, was the ignition coil, which also had to be replaced. *jb

Since I bought the car, I noticed on motion the force on the pedal started reducing. When it happens I repress it again which will become stable at that particular time. Will got stuck while in motion( 55mpr). I took to the dealership they told me nothing wrong with the car, and then I was under warranty. This morning I took it to mechanic, they told me it's electrical problem with throttle pedal and seat.

I purchased a 2008 Pontiac grand prix in march 2014 and shortly after when I tried to start it it didn't want to start. This has happened probably 10-15 times a month give or take maybe more seeing as I'm not the only one who drives it so I don't know but I know it's about 10-15 times a month for me. When this happens I have to give it gas to get going so I'm not stranded someplace and I'm not sure if this is an electrical problem an ignition problem or a problem with the fuel pump I'm not sure what's going on but I would like to have some answers due to this being a newer car than what we have and this being an issue that could cause me or someone else to end up being stranded due to the car not want to start properly. *tr

2008 Pontiac grand prix, total ignition failure, while driving without warning. Vehicle has only 39000 miles, and was properly maintained. There was no check engine light. Repair was to change ignition module and three coil packs. The fuse was also blown. *tr

I was driving at dark hours with headlights on and lights just went out. Turned on bright lights and the lights worked. Turned back to dim and lights worked for about half a mile.lights went out again turned on brights and same thing as before the lights worked. I thought I seen somewhere a recall was issued for this problem. I guess I didnt.

Back in the summer the headlights would not work on dim and took it to a mechanic and they replaced the hdm module under the hood. On december 23, 2013 the headlights would not work on dim again. Had to replace the hdm module again. It appears looking on line that this is not only my problem but others as well. This is a safety issue and should be dealt with by the manufacturer. *tr

Low beams on my car come on and off at the car's pleasure. High beams work fine but low beams will work then go off randomly. Fog lights work correctly as well. *tr

Headlights intermittently go off while driving. Happens 1-3 times per month & not every time I drive the car. Gm dealer tested extensively and could not duplicate in shop. Suggested I drive to their shop when it happens at night again, but not open at night! Gm recall on other cars with the same problem 12-2014. When I called gm they said there is no recall for the lighting issue I am suddenly having. They agreed to have the shop look at it again but per [xxx] at 866-790-5700 x [xxx], if they can't duplicate it in the shop "how can we prove there is a problem". I explained I had heard on the news that other gm car's had this exact same problem and would I need to video when it happens? He said we would start with the dealer but was not sure what would happen if they couldn't duplicat

The daytime running lights stopped working while I was driving at night. I could not turn them back on manually or by restarting the car etc. The high beams, turn signals, etc. Were not affected. The following day and for 2 weeks the problem did not reoccur that I noticed while driving during the day or night. After 2 weeks, the daytime running lights completely stopped working and I had to have the headlight relay module replaced. There is currently a recall on other gm models for this problem. *js

2008 grand prix low beam headlights/daytime running lights work intermittently or don't work at all. Lights will work when car is started and will go out as I am driving or will not come on at all. VIN search says no recall on my year, but this same exact issue is in recall for 2007 and 2006 grand prixs. This is a safety issue for my vehicle and I have now been pulled over and ticketed by the police for having headlight issues. I have tried replacing the hdm/headlight relay fuse, but the problem has persisted. I believe the issue to be the fuse socket or fusebox itself that is overheating the hdm

Had the power steering replaced 3 times in the last 3 years. Talked to others that have the same car they also have the same problem with the power steering unit leaking. My company had several grand prix's as a company car for years they also expressed this was a problem. I've had the lines burst on this unit as well. Also many of them said they didn't fix this they just keep adding fluid weekly. My thought is was thats not good for the environment. I lost all power when the high pressure line burst while going down the express way at 70 MPH. Not cool!

Excessive loss of oil (none leaking), blue smoke from exhaust. *tr

When driving the 2008 grand prix gxp (5.3 with a 4sp automatic overdrive) at low speed the car started shuttering and slipping in gear. Made it home slowly and pulled over and checked to ensure transmission fluid full. Call dealer to file warranty claim and tried to drive to dealer and car went 1/4 mile at 10-15 MPH and car transmission went completely out. No gears in reverse, drive or manual mode. Car had to be towed to dealer. This is a daily commuter car to work and home and I am working this week and has left me stranded during the holidays. No rentals available due to holidays. Complete transmission failure from a 2008 model with less than 100,000 and I put 12,000 on it since april when I bought it with 82,xxx. *tr
