NHTSA — Service Brakes Problems

2009 Pontiac G6 (Page 3 of 3)

CarComplaints.com 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.

problem #8

  • 63,000 miles


I was pulled over by a police office for suspected I was drunk driving. He said it was because of my erratic brake lights. After that by watching the rear window light at night I realized that my brake lights are on with no pedal applied, off when I apply the brakes and on again when I apply them hard. I now realize because the cruise control only works with the lights are off that this problem has been on going since I bought the car used last year. I took it to a shop to get fixed and the repair only lasted less than two days before failing again. I've read on the internet that this may become a recall but 2009 wasn't listed as one of the years. My G6 coupe 2009 has the same problem as described on the 05 thru 08.

When I press my brake pedal the lights go off but the rest of the time my lights are on (when I am not pressing the brake pedal) which has almost caused several accidents because the people behind me cannot tell when I am braking. It also causes me not to be able to use my cruise control because my cruise control thinks that I am hitting the brake which automatically turns off the cruise control.

My brake lights are staying on at all times, I have to pump the brakes before turning my car off or it kills the battery. This is a dangerous situation, one min I could step on the brakes and no brake lights come on...or they stay on the whole time.

Vehicle brake lights remain on except when brake pedal is pushed, then it goes out. This has not caused an accident yet, but it has high potential if a sudden stop is needed there will no warning for the vehicle following ours.

My brake lights keep staying on even when the brake pedal is not pressed. Went to the dealer and was told it is a common problem for Pontiac G6S. Been to the dealer 3 times in less than a year to get it fixed they just keep replacing the switch but now they say something else is wrong wires corroded. The 2005 G6 had recall for the exact same problem but my 2009 G6 is not on the recall list, same car different year.

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: 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.
