Brake lights stay on all the time. When first pressing the brake pedal they go off but then go back on after 3-5secs. Pushing the brake pedal further so the brakes actually apply, the lights re-illuminate. Cruise control also works intermittently which from other posts seems to be caused by this issue. My rear drivers side door lock just started working intermittently as well - could be unrelated however it all seems to be happening at once so something electrical is going bad. Looks like a lot of other people are also experiencing these issues.

The brake lights stay on all the time and when first pressing the brake pedal they go off and after pushing the brake pedal further they will re-illuminate. Because of them always being on the cruise control also will not work.

The contact owns a 2008 Pontiac G6. The contact was stated that the brake lights would illuminate without the brakes being engaged. The vehicle was not taken to the dealer. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure and current mileage was 80,000.

The brake lights on my 2008 Pontiac G6 are constantly on even when I am not pressing on the brakes. I have noticed that when I step on the brakes and release, the lights will turn off and about three (3) seconds later, they will appear again. My ECM and PCM were replaced due to my entire computer/electrical system shutting down but this doesn't appear to be related to the issue. Further, my mechanic has replaced my brake switch and that still didn't solve this issue. I am not sure what is in the works right now for this issue but we cannot solve it. Thank you for listening.

I bought my 2008 Pontiac G6 new with 3 miles on it. For the first 30,000 miles I had zero issues with the car. Since then it has had problems. The first was the steering column, while at a stop light the wheel began to turn itself. Steering became difficult to control and so I pulled over and used my cell to record the movement it was making on its own. The dealership replaced a computer module in the steering column.( after showing the video to the service manager and threatening to take it to the local news network) soon after the popping began in the column while turning. The module was under warranty but the "lube kit" for the popping in the column had to be out of my wallet to fix. ( oh how I love the ass hats at GM ). still have popping when turning. Then came the randomness to the headlights working. ( or not working ) replaced bulbs in low beam ( both sides ) several times and have noticed corrosion in connectors. Now the brake light are constantly on. The lights being on causes the cruise control to not work or shut off when lights activate on their own. I have also noticed my rear passenger caliper is sticking and eating pads, im on caliper number 3 as of today with countless pads and zero help from GM without having to fork over lots of money to fix a car (that obviously by the hundreds of complaints) was horribly built. Its pretty plain to see corners were cut in the production of this heap.

The contact owns a 2008 Pontiac G6. The contact stated that the brake lights failed to engage when the brake pedal was depressed and the brake lights would illuminate independently. Additionally, when driving with the cruise control activated, the brakes would independently engage and disrupt the cruise control system. The vehicle was not taken to the dealer nor repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 28,000 and the current mileage was 34,000... updated 09-18-13

I have a 2008 Pontiac G6. My brake lights were working in the reverse. When not depressed..they were on. When brake was applied..they were off. My cruise control also did not work. I took my car to my mechanic and he replaced the bmc and reset the computer. This cost me $412. It is now July of 2013 and the same thing is happening again. I researched it on the computer and have found out that this is a possible recall. Can I take my car to a GM dealership and get it repaired at no charge?

Cruise control stopped working completely following 8 months of intermittent outages. Stopped by state police officer and informed of brake light staying on. Confirmed break lights were staying on whenever brakes were not being apllied. When brake lights were applied, the brake lights would turn off for approx. 5 seconds. Fixed by applying dielectric grease to the electrical contacts of the main body computer.

Vehicle makes a constant popping noise when turning, braking, or accelerating. Sometimes the steering wheel locks when trying to turn it. Underneath driver and passenger floor board it feels like the bottom the car is falling off. The brakes squeak so bad. I have taken to three shops and everyone hears the noise but can figure out what is wrong. Sometimes when I get in the car the air is on full blast with no keys even in the ignition. This car needs to be recalled. I have read so many complaints about the same issues.

Brake lights do not shut off unless I press in the brake pedal. The cruise also does not work when this happens. It has almost caused several accidents. I have replaced the brake light switch and that did not fix the issue as the dealership said that is what it was.

I start the car the brake lights come on, I then step on the brake pedal and the brake light turn off. I have very narrowly missed being rear ended half a dozen times in three days thankfully no body has been hurt yet. I have a three year old son that rides in the backseat of my car! you guys need to get on the ball, the already known recall obviously needs to expand to at least 2008. How much longer do you need" this is how its gonna work, I go to a GM dealer, tell them my problem. They tell me "oh, its just the....." and I say "how do you know that?" "there is a recall but not for this year, so you'll have to pay" see the problem here"

Brake lights are on when pedal is not pressed...all the time! clunking noise in front suspension. On-line investigation shows hundreds of these complaints concerning this vehicle. Leaking/disconnected tubes in roof from sunroof drain tubes. Caused major leaks, wet interior, including under back seat. After removal of carpets and seat, musty odor remains and staining of headliner. There were hundreds of these reports on-line also.

My vehicle has experienced the issue that when I press the brake pedal, the brake lights go off and when the brake pedal is not being pressed the brake lights go back on again. It has cause many people to almost rear-end me in intercity driving and many pass me on the highway because they assume I am "riding my brakes." I've gone as far as to put dialectic grease on the body computer to prevent any corrosion, but this is only a temporary fix. We found that if we periodically unplug and re-plug the same computer it will "reset" the brakes for a temporary amount of time. I've tried contacting Pontiac about this issue but end up being repeatedly told that "there is no recall for my VIN on this issue." They didn't seem to care as much that I was calling out of courtesy to let them know so they can prevent any issues or fatalities. I was urged to go pay a GM dealer $$ to "diagnose" the problem so they could find out that way.......wow, thanks Pontiac, that's exactly what I want to do....pay money to help you expand your recall.

The brake lights will randomly come on and disengage the cruise control, the brakes will also drive around showing they are actively engaged.

I was driving and trying to set the cruise control and the cruise would not set. I was also being followed by my wife at the time. When we arrived at our destination, she asked me if I was riding the brakes. I told her I was not and she informed me that my brake lights were on all the time, except for after making a stop & restarting they would go out briefly and come back on and stay on. Since that day this has happened intermittently several times and this concerns me very much as I have a 16 year old son who drives this vehicle to work and you never know if the lights are stuck on unless you try to engage the cruise control.

Brake lights self-illuminate, canceling cruise control functions as a result. General Motors has issued a technical service bulletin on this issue (#08-05-22-009: Intermittently brake lights (stop lamp) do not function correctly, extended travel to shift out of park, cruise control inoperative, dtc C0161/C0277 set (perform repair as outlined) - (Dec 4, 2008) ), enough vehicles are affected by this issue to warrant a safety recall.

My brake lights will come on and stay on until I shut the car off. It appears I am riding my brakes which I am not. Please look into this and potentially recall the defect. It can cause accidents to happen.
