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 — Electrical System Problems

2009 Pontiac G6 (Page 1 of 6) 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.

My brake lights will come on when I am driving and will go off when I apply the brakes. Also I will have warning lights come on randomly. Same issues under NHTSA campaign number 14V252000. Dealership has done recall work for this twice they told me and have charged me for the repairs and repairs to my warning lights as well and it is still not fixed. This happens everyday.

I've been replacing parts to try to solve the problem of why the brake lights stay on, the cruise control kicks off, the traction control stays on. All these problems are all at the same time.I get it fixed and then 3 weeks later its the same all over again but it keeps getting worse. Alot of people I know with this car keep spending money and it never gets fixed the right way. We all need a solution.

The low beam head lights are melting there connector makingthe lights to go out random and some times blowing the light bulbs. This happens at any time day and night in motion or not. It is extremely dangerous when the lights go out and im driving as I can't see anything and other drivers can't see me. The high beams do work but that is dangerous to drive with any traffic as it can cause them to not be a be to see.

The solution GM has for recall #14V252000 does not work. The recall was fixed 9/2014 and on 10/31/15 the same problem was noticed. This has been noticed when the vehicle is in motion. Brake lights come on when brakes are not applied, go off when brakes are applied. I brought vehicle into a Chevy dealership on 11/09/15. They replaced a brake pedal position sensor. Noticed on 11/09/15 in pm that the brake lights remain on and do not change when the brake is pressed. A service traction came on 11/10/15 and again on 11/17/15. I have not had an opportunity to drive behind the vehicle while this service traction light is on. I have taken a picture of the service traction light twice showing the mileage and time. I have read similar complaints regarding this NHTSA recall #14V252000 (GM recall #13036) on this website! I know this will not be taken care of unless a number of people die from an accident just like the ignition switch recall!!

My vehicle was recalled last year due to a problem with the body control module. I brought my vehicle to a local GM dealer to be "fixed" and now my car is having the exact same problems as before: Loss of cruise control, malfunctioning brake lights, loss of traction control, difficulty shifting gear out of park position. These problems began occurring in 2013. GM should have told customers that the "fix" was temporary, as I was almost rear-ended multiple times yesterday due to my brake lights malfunctioning. This is dangerous and someone could get injured or killed due to the issues with the brake lights. After receiving my recall notice and taking my car to be serviced, I thought I would never have to worry about this again. It turns out the mechanics at the GM dealer just cleaned the BCM and applied dielectric grease to it, which is what I had been doing before the recall even came is insulting that they would consider this a "fix" and endanger their drivers, when they had to know that this would only help temporarily. It seems the entire BCM needs replaced to actually fix it, which is expensive. GM should cover the cost of this, as I know I am not the only driver having repeat issues after having the car "fixed" during the recall. My car has now also lost power steering on more than one occasion (loss of power steering first occurred this year), and my headlights keep going out, even when the bulbs are brand new (this has been an ongoing issue for two years now). When I smack the headlights, they come back on. I see that other drivers are also having issues with their power steering and headlights, as well as with the BCM. I am disappointed that GM has not provided a permanent solution for these issues, and I do not always feel safe when driving this car.

The wipers failed to work. But after 10-15 minutes of the vehicle operating they began to then work. Sometimes the wipers would work with the washers and high speed only. When the wipers were left on and the car was parked, the battery drained and was dead the next morning. Then the engine on two occasions attempted to start itself when sitting and not on. On one occasion it successfully started itself. On several occasions the interior dome light stayed on.

I purchased car new in 2009 and have had problem after problem starting with exhaust system just weeks after I got it. It has had 3 recalls but I more are due. The headlights started going one after another and at one time all front lights were out at the same time. I had them repaired with new connector. Currently, the left headlight is out again and a new headlamp and another connector was installed and still will not stay on. Other owners I have spoken with have the same problems that I am having. But what can we do? I've been experiencing power steering going out occasionally for no apparent reason what so ever. There is a recall but my car is not covered under the recall although there were 2009 models that were. I was told my VIN number wasn't included in the recall. The air bag alert stays on. I had it diagnosed along with the seat belt alert and both need to be replaced. The seat belt sensor module needs to be replaced in the passenger seat. My rear door locks don't work and that's electrical problem. I feel the car manufacturer knew these problems existed and should be held accountable for selling these death traps. With all these serious problems, I can't grasp why GM don't take responsibility for all this and get them off the rode. I and other motorists are not safe while I'm still driving this car. Do the right thing GM and recall all 2009 Pontiac G6 and make them safe.

We have had ongoing issues with the rear running lights shorting out and the driver's side low beam going out. We replaced fuses for rear running lights 4 times. I was pulled over by local police and had to be picked up to get home, leaving the car at police station until I could drive safely in daylight. We have replaced the low beam bulb 3 times. The low beam light would intermittently work at times. Now, again it is not working at all. I have read excessive consumer complaints stating the same problems with 2009 Pontiac G6 vehicles.

Low beam lamp passenger side out. Not knowing any better I. bought a new sylvania bulb. Two weeks later out again. I did a little research and found this is a huge problem with G6; GM & more than likely too expensive for me to fix immediately. I just bought car from dealer & on ssdi; therefore, have no money to even purchase another bulb let alone housing, connector stuff etc.. this is a safety issue with a tremendous amour of vehicles; see carfaxs on this model. Although my carfax was clean I now think this is why car sold by old owner.
