This is the second time the headlamp assembly wiring harness and connector has melted. A year or so ago the passenger side harness melted and now, the drivers side has melted. I am concerned about this being a potential fire hazard, if parts are being melted. I have done an internet search and have found that many other people around the county are experiencing the same problem.

The first incident occurred in 07/2013 with approximately 60,000 miles on the car. The ground connector on the low beam headlight socket on the drivers side was melted and the light would not work. The connection was cleaned and the bulb was replaced. The headlight again went out around 10/2014 with the low beam headlight socket having additional melting at the bulb connector and corrosion on the wires. The headlight socket was replaced. It stopped working less than 1 week later. The headlight socket has been melted and both the socket/bulb need to be replaced again.

Headlight and tail light bulbs are melting at electrical contacts causing frequent bulb failure. The last time this happened with the drivers side headlight, not only was there damage to the bulb's electrical contacts, but the wiring harness itself had melted. After complaining to the local GM dealer, they informed me that they no longer made the part and I would have to "splice" in the harness from the GMC arcadia. I do not find this as an acceptable solution as the spliced points will eventually fail also. Furthermore, what normal car owner can or should do this themselves?

Bought a used 2008 Pontiac G6 one week ago. It had an open recall--13036. This was a brake lamp malfunction which could also affect the electronic stability control and traction control (disabling them). Also possible problems were brake lights coming on when accelerating and going off when braking. This also affects the cruise control and the shifter. Had the recall work done today, October 3, 2014. By the time I got home, brake lights were continuously on, cruise control did not work, and traction control and ESC were disabled. This after GM's recall.

My 2008 Pontiac G6 has leaked water since the day I bought it; however, I did not know how bad it was. Finally, the water leaking in ruined an electrical component - the accelerator pedal position (app) sensor. Upon investigation I found black mold all over on the inside of my car (under the carpet). Finally, GM decided to fix the leak, plus clean my carpet. Unfortunately, within 8 months it was leaking again and black mold is all over under the carpet. I worked with GM and the dealership for months; they took a very lazy approach to my situation and did not seem to care. You can actually smell mold when you get in my car. During this timeframe I have become ill and have had many (a lot of) symptoms associated with black mold exposure. General Motors is fully aware of the health concerns, but they don't really care. Clearly this is not a freak occurrence.. another complaint I found on this website from someone else: "the contact owns a 2008 Pontiac G6. While parked, the contact noticed a large accumulation of water on the front passenger's side floorboard. The failure recurred after rainy weather conditions. In addition, there was mold under the front and rear passenger's side carpet. The vehicle was taken to an authorized dealer where the air conditioner was repaired. The problem recurred two times and the air conditioner was repaired each time. The contact had concerns of the health issues related to the mold. The manufacturer was notified of the problem. The failure mileage and VIN were unavailable."

Rear passenger door will not lock/unlock. Loud, rubbing noise coming from steering column when making turns. Low beam headlights work intermittently (got stopped by a policeman and warned of a citation the next time I would get stopped). I changed the bulb twice. Low beam headlight will stop working, but the bulb is not actually burned out. As a result, I had driver side bulb wiring replaced by dealer, due to charring that was present on the wiring harness. Then, it started working again. A month or so later the other one went out. Now the passenger side wiring is charred, but the bulb is fine.

When I was driving my car all of a sudden the headlights started to flash/turn on and off uncontrollably. I took it in for service and the dealership concluded that my wires has melted and fused together. He told me that I was lucky that there was not a fire that started, that is how bad they were melted. I had to replace wiring harness and get new bulbs, which cost me $400. There are many complaints about this issue in online forums and I am scared that something like this could happen again. I believe that it is related to the May 14, 2014 recall regarding the electrical system, electronic stability control, vehicle speed control. This is terribly dangerous and needs to be addressed by GM before more innocent people get hurt, please help!

While driving at 70mph on the freeway, every light on the dash came on. Speedometer stopped working but car continued to run though roughly. Was able to pull off the interstate. Turned the ignition off and car engine stopped running but all the dash lights stayed on and blower motor continued to run for about 10 minutes. Had to have vehicle towed to dealership. Was told the fusible link failed between the alternator and the starter. Was told it was not in conjunction with the recall (13036) for BCM voltage fluctuation. Dealership performed recall repair but vehicle had to be brought back a 2nd time to recalibrate the BCM.

I have a 2008 Pontiac G6 that constantly has issues where the low beam bulbs will burn out. It kept getting worse as I was replacing them every 8-9 months. I just went to go take out the burned one the other day only to find that the whole socket the bulb is connected to was completely melted along with a nasty burn smell emitting from the back of the headlight assembly. Thankfully GM gave me an extended warranty due to constant problems with my car surrounding electrical issues so my car is being fixed my a local GM shop this coming weekend. This seems like a serious problem because other G6 owners have reported the same problem. There is something seriously wrong with these Pontiac G6 cars and GM needs to reimburse each of us for the full price we paid on these vehicles. Of you compare the amount of problems on this car vs all other cars on the market, this one by far has the most complaints on the national highway safety site. Of I had the money I would buy a new car that is not american. I hate my car so much. I hate GM for making me drive such an unsafe vehicle. There are two recalls still pending (according to the dealership) involving the brake light issue and shift cable issue. The dealership doesn't have the parts for either recall. This is such bs. Also, the dealership told me that they don't have to give me a loaner to address the recalls. From what I've read online this is illegal and they must provide one.

  • 135,000 miles
To sum it up started getting "engine power reduced" message from message center in vehicle. Shortly afterward the vehicle will begin flashing the traction control off light and shifting hard. Now the vehicle still shifts hard with the two above messages and is also stalling out when "engine power reduced" message appears. Many times after this the vehicle will not accelerate at all. Have to pull off the road, cut the vehicle completely off for a few minutes and then continue driving. Problem started intermittent and now happens every single time I drive the vehicle. I have had it stall out on the highway going over 50 mph, very dangerous was almost hit. Vehicle has been at the used lost service center three times, no luck on finding problem or repair. Car has been with my local GM certified dealership for 3 days and still no proper diagnosis problem or repair. Has sense received the two recall letters BCM/transmission but dealership is reluctant to repair because they said GM may not pay for time and parts. Worse car purchase I have every made.

Replaced both front headlight bulbs on multiple occasions. Replaced entire headlight unit to driver side and passenger side. Both headlight bulbs were out- new bulbs- wiring harness melted, along with other electrical issues associated with vehicle such as hot faceplate to radio; interior door handles; and shifter box. Recently the traction control message appears on the radio message area. Additional issue about a year ago wherein another driver informed me that I had no working rear brake lights.

I was traveling on U.S. 30 to greensburg, pa and I went on to the off ramp on to West pittsburgh street and the traction control, stability lights lit up. I look down at the dashboard to see what going on. Then, my car jerked suddenly backwards I hit my head two or three times off the head rest. I hit the on star button to report what has happened to verify the codes and told them the situation. The on star people didn't even ask me if I needed medical attention. So, I drove to the hospital that was 1/4 mile away. I was diagnosed with a head injury and received treatment for neck and back injuries.
