Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Was driving down road and smelt a burnt odor, found out my low beams where not working. Once home, I popped the hood, opened the fuse box and found it smoking. Quickly disconnected battery cable. Further observation, found low beam relay started melting and must have caused small fire. Burnt part of the fuse box.

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 function of lights/lighting system to pinpoint problem. Left alone, electrical components can fail and result in vehicle electrical fire. See attached photo of fuse block showing damage to area for parking light fuse.

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.

2008 Pontiac Grand Prix. Consumer writes in regards to ignition switch recall problems. The local GM dealership informed the consumer, they do not replace the ignition switch. All they do, is insert a small plastic ring in the key, so the consumer cannot attach a larger key ring to the key. The consumer believed it was very deceptive and it went against the intent of fixing the problem.

Lowbeam headlights suddenly quit while driving causing me to almost run off road. This is directly related to the GM recall #14291 concerning the sudden failure of the hdm without any warning. The recall not cover my 2008 Pontiac at this time. Was told "under investigation". this needs to be immediately addressed by GM or federal government since it is a deadly matter. Sudden loss of lights at higher speeds will cause deaths.

Was stopped at a red light and my car just died. Had to get it towed to the garage. They responded that the ignition coil was fried which fried 2 other ignition coils and the ignition control module. Cost of repairs $700. If I would have been driving my normal highway driving at 65 mph would my car just have shut down on the highway? this could have been a safety issue if the car died right in the middle of the crossing. Now I am without a car for 2 more days because parts need to be ordered, then fixed.

We purchased the vehicle from a dealer inthe tri-cities area of eastern Washington in 2010. The car may have been a lease return. However one of the selling points with the car was the remote starter option. The weather in eastern Oregon where we lived at the time was a life saver. However when the battery went dead and replaced at the dealer the remote start quit working. Not only quit working but it even disappeared from the vehicle dic. The remote start is even listed in the vehicle owners manual. But the dealer in medford, Oregon, air port Chevy/caddi cant seem to figure it out. We have had the vehicle at the dealers in medford 6 times. Even during the recall for the key fob issues and ignition switch fires, the dealers also looked into the darn failure of the remote start but they never did fix anything nor do they have any ideas as to get the thing fixed.

2008 Pontiac Grand Prix lost total power to the car. Discovered that the ignition module had gone bad. 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.

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.

Within a month of purchasing a pre-owned 2008 Pontiac, Grand Prix from mike smith Buick GMC, located in lockport, NY, I realized the sensor for the passenger airbag would turn off and on while I have a passenger weighing over 200lbs in the passenger seat. I notified dealership and made an appt. On Sept 22, 2014. My car went in for service on September 29, 2014. The technician informed me he reset the module but no codes were coming up for the electronic control unit and this was too expensive and time consuming to fix and would not be covered under the New York state lemon law warranty. This concerns me as a safety defect and I would like to know if this is covered under General Motors corporation.
