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.

I replaced my driver and passenger low beam bulbs on two different occasions within the past year. Well low and behold my passenger low beam bulb blew out again! as I disconnected the headlight, I noticed the wire harness had melted!!!! luckily, I am alive to tell about it! upon reading all of the other individuals' reports on this matter, it is alarming that there was no recalls for this damage by GM! GM needs to make this right! I trusted GM...... only to be betrayed! faulty wiring!!!! this is B.S. an unsatisfied GM customer, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was driving down the street and noticed I couldn't hear the turn signal click. When I got out of my car, I check to make sure they worked. They did. I then turned my car off and then on again and the warning chime did not make noise. If a seatbelt is not on, the chime no longer sounds either for both the driver and passenger sides of the vehicle. I can't tell without visible looking if my turn signals are still on when driving or if the passenger is wearing their seatbelt.

The contact owns a 2008 Pontiac G6. The contact stated that while driving approximately 35 mph, the check engine sensor light suddenly illuminated and a chime sounded before the vehicle stalled. The vehicle was restarted and functioned normally but the gauges were inoperable. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 67,000.

Low beam headlights go out often and both lights will go out without warning. The high beam lights work ok but cannot be dimmed for oncoming traffic when this happens. Changing bulbs does not fix this problem.

Brake lights remain on when the brake pedal is not pushed, but go off when the brake pedal is pushed, just the opposite of what is supposed to happen. Following vehicles cannot be signaled when slowing down creating danger of a rear end collision. The problem is intermittent can tell it is happening when the cruise control does not work.

Door locks stopped opening back doors or on occasion wouldn't lock or unlock. If I am in a situation and someone is in backseat the doors would remain locked. I would have to roll down windows to unlock the backseat doors, before I could get an infant passenger and remove from car seat. Lord forbid I'm on train tracks.

Vehicle battery was drained overnight from consumer electronics (dvd charging, gps) to the point when attempting to start near zero voltage with inside lights shutting off. Charged with 10 amp battery charger to full battery. Afterwards key fobs would not work. Did not think much of it. After a few days of driving noticed the tire pressure info was all -- (not posting). Tire pressure system monitoring was completely off with no notification to driver. Found several sites that say a G6 can lose it's tire sensor/key fob memory from a slowly draining battery and must be taken to a dealer to fix it. Took it to a GMC (formerly Pontiac) dealership, $95 later only got the tires working again. Newer vehicles have a procedure for owners to initiate this setup themselves and reprogram the tires and key fobs, but not 2008. The lack of tire pressure sensors when they were there prior should trigger at minimum a warning on every start. It can tell me I need an oil change every day. For this to happen because of a low voltage event is terrible circuit design / bad programming. If an owner charges his kid's dvd player and it kills the battery the next day the mandatory tmps system may not work, and not work without warning. Hopefully the day the dvd player needs a charge isn't the same day they develop a medium leak driving down the mountains of Utah, because the driver won't be notified the system forgot the sensor id's and doesn't care about those pressure readings anymore, even the falling pressure on the tire holding the car in the correct lane at a 8% grade, downhill. #1 fix the safety issue. #2 don't charge me to re-program something that is not safe and was corrected on newer vehicles.

The service airbag light comes on and so does the tire inflation warning at start up and stays on.. this use to be occasionally and then not come on the next time you started it does it almost continually..also the seats electric height adjustment has broken free of the base on the floor...the weld has broken on the tube on the base of there car...I see so many other car owners with the same exact issues yet no one is addressing them or issuing a recall...theses issues should not be fixed at the owners expense when GM knows there is an issue and a seat in a car should never have welds fail this is a major safety issue..these seats would never hold up in a crash.

The airbag light has came on and the passenger seat will not show someone is sitting in it for the passenger airbags. The light first came on in February but went off a few days later it then came back on in March and will not shut off. The dealership will not fix it because there is no recall on it. If a crash happens my airbags will not work. Also I have had my engine for my windshield wipers replaced three times 600 dollars later my wipers do not work. They keep telling me it keeps snapping I can't keep spending money onthis. Also my gears do not shift properly even though the transmission checked out good. There is a recall for this but the dealership refused to fix it stating the part was not received yet. I haven't received any recalls by mail even though there are plenty of them. This whole car needs recalled.

Both of my head lights have gone out. My first headlight went out and the dealer stated that my wires had corroded and needed to be replaced. Now two months later my other headlight is out and I believe it is the same issue. Also I have been having trouble with both cruise control and my turn signals as both have not been reacting to the command. I believe that it is related to the May 14, 2014 recall regarding the electrical system, electronic stability control, vehicle speed control. I spent over $500 to replace the first headlight. The other items have not been replaced yet, but I know they will need to be and the cost will be exorbitant.

It appears there are four (4) recalls on this model/make/year - we have never received a single recall notification. NHTSA campaign # 14V252000, #14V224000, 14V153000, 12V460000. I would appreciated further information in correcting identified recalls.

Faulty wiring in the Pontiac G6 headlights causes the low beam headlight socket to keep melting causing an inoperative bulb. This could potentially cause a fire since it is not tripping the fuse.

Vehicle headlamps fail regularly every (1-2 months). It appears there is a power fluctuation just before the lights fail.

In 2013 the driver side headlight went out. We replaced the light. Notice a couple weeks later light out again. Brought to mechanic and found wires to be burnt/melted. Had to have the whole headlight assmebly assembly replaced. Has been quite some time and we have recently replaced the light 2 times in the last 2-3 months. Wires are somewhat dark burnt at the connection as before. I believe this is an issue with these vehicles and it needs to be fixed.

Headlight works intermediary. Found connector to bulb was discolored & slightly melted. I believe wire may be too small to carry the load. This has appeared multiple times on the internet featuring a lot of GM vehicles. GM apparently has a replacement fix so they know about the issue.

In August of 2013, I noticed a strong gas smell when standing towards the back end of my G6. The problem was a bad fuel pump. Mileage was ~58,000. A few weeks later, my car began stalling and the charcoal canister had to be replaced. It is now may, 2014 and I've had my car back to the dealership for fuel system related issues five times. They've replaced the fuel pump and charcoal canister a total of three times and they even replaced the gas tank during round three. After the most recent repairs, I get "check gas cap" messages on my radio console every time I fill up, my check engine light comes on and I have acceleration issues. I'm just waiting for it to stall on me again and I pray it doesn't happen again on an on ramp. All repairs are documented through the dealership. In April, both low-beam headlights began working sporadically and within a week, quit working completely. I went to a shop close to the office and paid $50 to have both low-beam bulbs replaced. After about three weeks, the driver's side bulb was out again. I returned to the shop and they took the head lamp out and showed me that the problem was in the wiring harness of the head lamps. The wiring had become so hot, the wire insulation had melted off and the wires are exposed causing a short and blowing the bulbs. I'm now concerned that the electrical issues are more widespread and could be contributing to the continued problems with the fuel system. The dealership has been great to work with, but if the manufacturing dealership can't resolve these issues, I'm not hopeful that my car will ever run correctly again. I feel I have a great looking, unreliable lemon that adds a great deal of stress to my life. I can't afford a new car and I hate that I don't feel like I can go very far from home out of fear of ending up stranded or I won't make it home before the sun goes down.
