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.

NHTSA — Exterior Lighting Problems

2009 Pontiac G6 (Page 5 of 7) Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

G6 6-cyl

  • 60,363 miles


2009 Pontiac G6 low beam headlight failure: "unable to find the problem" as beams work intermittently; my local mechanic replaced left light bulb, but referred me back to dealership as "this was a known defect in this car." Replaced light bulb (repaired (mechanic was unsure, but replaced anyway) and low beams worked a couple of days, now one (right more randomly left), and sometime both low beams fail intermittently. My wife has received one warning from police; headlight was working again when she restarted car after the warning. With increasing frequency both low beam head lights fail while driving at night. These random failures in low beam illumination requires the driver (my wife usually) to immediately switch on high beams. Both high beam lights are working at this time, but these events tend to infuriate oncoming drivers who high beam back at us, so both drivers are blinded. In my opinion, this vehicle is unsafe to drive at any speed at night or in the rain due to random low beam headlight outages. Therefore, we use of the G6 is limited. Though we like the model and had hoped for several more years of use, my wife does not trust the lights will stay on at night, or when it rains. I feel bad about dumping this car on the used/pre-owned car market without filing some form of official complaint. From a brief internet search, the manufacturer (GM) appears to be ignoring this safety issue as a statistically insignificant problem. Sadly, GM will continue to do so until people die and a class action suit is filed. I would not call the Pontiac G6 a lemon, it is just plain too scary to drive under certain conditions. There does not appear to be a solution coming from GM and my mechanic can't fix it. This situation makes this vehicle useless and unsafe half the time, I.e., unsafe at any speed after dark!

My brake lights are intermittently staying on while driving even though I am not using the brake pedal. The scary part is that they shut off when you hit the pedal and then come back on about 5 seconds later. I saw on the web that there is a known problem with corrosion on the BCM connections. There was a recall for previous years and GM has issued a technical service bulletin on how to fix it because there have been so many problems and complaints. I am going to try a quick fix I found on the Pontiac G6 forum before I have to take it to a dealer and spend my own money on an obvious defect.

Noticed headlight burned out. Replaced it. Burned out again in a week. Replaced again and burned out in two days. Replaced with best bulb available and has been intermittent after one week. Read many posts online about this problem. Now I need to have a mechanic troubleshoot a flakey electrical problem which can be very expensive. I believe any safety equipment issues should always be warranty work from the dealer.

The brake light on the 2009 Pontiac G9 intermittently go off and on. Brake lights are on while the brakes are not applied and go off when the brakes are applied. This issue could cause a serious accident.

I own two 2009 Pontiac G6 vehicles. Both of the connectors in the headlights of each vehicle have melted and need to be replaced. One has been fixed and the other is waiting to be fixed. They happened at different occasions. This seems to be common with these vehicles and the manufacturer is not taking responsibility for the problem. Please make others aware. I also had a problem with motors for the door locks on both cars going out at the same time. Thank goodness that was under warranty.

Was driving and notice my brake lights were staying on even though I wasn't hitting the brakes at the time, then when I would apply the brake the lights went off when I let up on the brake lights would come back on if this problem keeps going on with this car it is going to cause someone to have a wreak and get hurt.I think the company needs to have a recall on this part before someone sues the company for wrongful death. I have read many complaints on this issue and its time for the company to make a recall on it.

2009 Pontiac G6 I got on the highway and tried to switch on the cruise control and it wouldn't work so I pulled over to the side of the road to see what's wrong. When I got out of my car I noticed that the brake lights were on so I went back and pressed the brakes then they turned off. I started driving again but soon as I turned on the cruise control it comes on but turns right back off. But if I hit the brakes the cruise control will work again for a second then turns right back off that's when I realized that the brake lights come on when I drive but when I hit the breaks they turn off. Im only writing this because my car doesn't have 100,000 miles yet and I saw that your company started an investigation regarding this issue. I would like to know how this can be fixed because it's not just on the highway it's happening now all the time. This can be a safety issue so I'd rather get this fixed now. Please help. Thanks!

G6 4-cyl

  • 37,000 miles
I had someone following me home the other day and when we arrived they asked me why I kept putting on my brakes and letting off. I was not touching the brakes. We cranked up the car and stood behind it and watched and the brake lights would come on and go off without anyone even sitting in the car. I got in and started pressing the brake pedal and when I pressed the pedal the lights would go off. When I let off of the pedal the lights would come on. That's when I started searching this issue and found all the other people out there that have had the same issues with their G6's. in my opinion and everyone else that has this problem, this is a major safety issue. My daughter drives this car and it makes me extremely worried that something could happen. How in the world can GM not be taking action to resolve this problem considering how much talk they advertised about the quality of the new G6? GM needs to stand up and do the right thing here before someone really gets hurt or dies due to an accident involving these brake lights.

Passenger side lowbeam went out, replaced bulb and it went out again, inspected wiring harness and noticed it was charred and melted, and the wiring near it was also charring and insulation burning off. Replaced wiring harness, bulb went out again a few days later, inspected new wiring harness and noticed it was melting again. Suspect short as even the wires are getting very hot, however no fuse has blown to date. Concerned about sudden lack of visibility at night and about fire risk.

I noticed that the cruise control was not working, soon after that someone told me that my brake lights are on most of the time, only going off occasionally. I have tested it, and you can put the car in park and watch the lights go from off to on with out touching the break petal. (they stay on) I am going to take it in for service tomorrow. I have found out this is not an uncommon problem. This should be a recall issue. I know this problem is under investigation. There are tons of complaints.
