While driving, cruise control will disengage and brake lights will flair on. Than when tap brakes, brake lights will shut off. Within a couple seconds, they will turn back on. When actually going to press on the brakes, have no brake lights than. This has also happened without using cruise control, just driving in general. Break lights will come on, than when press on the brake, they shut off. Couple seconds later, come back on. This is a huge safety issue while driving at night time(or during the daytime), not having brake lights when stopping. Do not feel safe driving with my children in the car. I have looked online, and found that I am not the only one having this issue: http://www.g6ownersclub.com/forum/showthread.php?t=6657 is a forum/thread of various g6 owners complaining about this issue and also believes they have come up with what the problem is. From what it sounds like, its a connector with the bcm (body control module) and it developing corrosion.

Tl* the contact owns a 2009 pontiac g6. While driving approximately 35 MPH, the brake lights illuminated without depressing the brake pedal. When the brake pedal was depressed the brake lights would not illuminate. The cruise control also disengaged whenever the brake lights illuminated although the brake pedal was not engaged. The failure was diagnosed by the auto shop mechanic where it was purchased. The mechanic stated the brake switch had to be replaced. After the vehicle was repaired, the failure continued to occur. The approximate failure mileage was 42,000.
The brake lights on my car are on sporadically. They come on when the brake is not pressed. The brake lights do not come on when I press the brake either. This is a danger beacuse I have a long commute to work and I have no way of warning drivers when I am slowing down or stopping. The issue also causes my cruise control to malfunction.
I have a 2009 pontiiac g6. The front rotors warp and the whole front end shakes. I had them cut a couple times and I only got about 8000 miles before they warp again. So I bought new rotors and the same thing happened again.so its not the rotors its the way the car is built.
I have a new 2009 pontiac g6 and the brakes squeak terribly. Many mechanics have said this is dust causing this. I do not agree. There has to be something wrong. I have had many other vehicles and this does not happen. Pontiac should be responsible for correcting this issue. It is a total nuisance. How do I know the brakes will not go out. They did not squeak when we test drove as if it did, I would have never made the purchase. I am very dissatisfied with this new car.
Tl*the contact owns a 2009 pontiac g6. While driving at any speed, the brakes squeaked. The contact took the vehicle to an authorized dealership twice where the rotors were resurfaced. The failure continued to occur. The contact called the manufacturer and filed a complaint; the manufacturer stated that if they could not find a mechanical failure, they could not assist. The failure mileage was approximately 26,000. The current mileage was approximately 34,000.
Tl* the contact owns a 2009 pontiac g6. The contact stated that the breaks squealed when she engaged them.
