While driving city or highway brake lights come on. When you push brake pedal while this is happening brake lights go out. The brake lights are working opposite of what they should. When brake lights come on while driving if you tap brake pedal lights will go out for 5 seconds then come back on. Very dangerous driving with this issue. Car was recalled in 2014 and taken to dealership for recall fix. I never had this problem unroll now. Recall number14V252000 for corrosion in back connection. I had brake switch replaced and had computer reprogrammed 3 times now and problem persist. GM 2014 recall fix for the problem is not a fix. Car is unsafe to drive

While driving the car's brakes illuminate automatically. While applying the brakes the brake lights turn off. This happens while driving in the city and on the highways both. Therefore causing any vehichles behind me to think I am no longer slowing down. This has been the case since 2009 when I first purchased the vehicle. I have taken it in to several local dealerships and auto shops. No one can seem to fix the problem correctly. This is a huge concern for my safety every day when I travel in a busy downtown area.

On a clear day, traveling on a local hwy, check airbag light came on, stayed on. I have been asking other owners if they have the same problem. I was told the airbag won't deploy if that light is on. That scares the hell out of me! now the seat belt light is on because I moved the drivers seat forward. That is intermittent. Please, find the right person to declare this worthy of a recall. One person dying because of this is one person too many. Airbags and seat belts are our only safety in a car. If we don't have that, the cars should be taken out of service by the manufacturer, and the owner reimbursed.

Just acquired the 2008pontiac G6 for my son. Learning there were 2 open recalls on it. Called local GM service center and had them done. Now a seat belt light for the drivers side pops on upon starting the car, driving the car and only goes off when the car is turned off. There's a light for the drivers side airbag that stays on. It is on when you start the car, it's on when you drive the car, in town and the highway, it only goes off when the car is turned off. A new battery was added to the car, and new serpentine belt. I have a vapor lock issue today. Please tell me this car will protect my son if an accident happens. The air bag issue worries me. Is there an open recall, or one that has expired, and may be reopened? please let me know. Thank you.

G6 6-cyl

The contact owns a 2008 Pontiac G6. While driving various speeds, the brake lamps illuminated without the brake pedal being depressed. When the brake pedal was depressed, the brake lamps failed to illuminate. The vehicle was taken to a dealer where it was diagnosed that it needed to be repaired per NHTSA campaign number: 14V252000 (electrical system, electrical stability control, exterior lighting, service brakes, hydraulic, vehicle speed control). The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

The brake sensor goes out causing the brake lights to not work. A recall says that the BCM causes fluctuations to the brake sensor, in turn causes the lights not to work. When I had the recal done for the BCM, the brake sensor also needed work. The result is 200 bucks worth of work done that wasn't recall covered. The recal even states that the brake sensor is affected because of the BCM problem. I believe that the brake sensor needs to be covered in this issue. Also include the traction control shutting off, that was another 200 spent for that. Take a good guess what was the result of that issue. Spoiler alert it was the BCM!!

Driver side front low beam light was out and replaced at pep boys in April 2016. Since then the light would work intermittenly. I returned to pep boys and was told it was probably an electrical problem that they see 9 out of 10 times with Pontiac. Went to dealer on 8/22/2016 and was told that the bulb connector had melted, a problem that is very common with this car. I had to pay $212.17 to replace the low beam connector and the new headlamp that I was told could not be re-used. I am now hoping it doesn't burn out again soon or that the right side doesn't burn out too. This is a dangerous problem because I never knew when my headlight would be on or if it would remain on during an outing. Sometimes I would board my car and begin driving with the light on and part way through my trip the light would go off leaving me suddenly in the dark. Luckily I was never stopped and ticketed by the police or, even worse, suffered an accident due to a sudden change in visibility on the road.

I am so aggravated with the Pontiac company, I filed a recent complaint over the phone. The body control modular needs to be repaired/replaced but because my particular car was not included in the 2014 recall they are refusing to do anything about it. The dealer I had to take the car to is trying to blame it on us because the car has after market items on the car which we did not addto the car, when we bought the car from Toyota on nicholasville superstore that stuff was added already by someone else, and if that was the problem why is the brake lights on//off problem just now showing up since it was a year this past may that we have owned the car. I think that the Pontiac company just doesn't want to help fix the problem and we are stuck with a car that has brake light issues that could cause serious damamgung problems in the future and I have no way to pay for it to be fixed.

G6 4-cyl

  • Automatic transmission
  • 76,000 miles


The contact owns a 2008 Pontiac G6. While driving at any speed, the brake lights remained illuminated regardless if the brake pedal was depressed or not. In addition, the traction light illuminated. The failures occurred continuously. The VIN was excluded from NHTSA campaign number: 14V252000 (electrical system, electronic stability control, exterior lighting, service brakes, hydraulic, vehicle speed control). The approximate failure mileage was 76,000. Updated 08/30/16 the consumer stated the brake either illuminate all the time, or they do not illuminate at all. The electrical system would go haywire. The seat belt alarm sounded even when it was un-buckled, the traction control light illuminated and so did other random lights. Updated 10/26/16.

Tail light recall repair completed in 2013 - car has been back to dealer numerous times for same issue. Tail lights come on when driving an go out when you hit the brake pedal. I was almost rear ended by a semi last night as the brake lamps were not operating correctly. Dealer closed out the case as repaired - GM recall line will do nothing and want me to pay $120 an hour to have the car put onto diagnostic machine - I refuse to pay out of pocket for anymore expenses - I've paid over $500 already before recall was extended to 2008 models. I work at a GM powertrain plant, this type of repair is unacceptable to my standards of what management tells us quality is to GM. Please investigate further their fix was a jump harness and re-greasing of the BCM - that is not the fix the real issue is the BCM's are bad and need to be replaced my GM reference id for this issue is 8-2214129861. I do not feel safe driving this car at night with no working brake lights. Issue happens while idling, city driving, and highway driving. Traction control and electronic stability control lights come on along with scrolling on car screen to service traction service ESC. Cruise control disengages and all traction stability of the car is turned off.. pressure in the brake pedal also goes.

When I tried starting my car it wouldn't do anything so I had to put it in drive and then it started up and that happened to me three times so far it's like it want start unless I turn the ignition and put it in neutral for a drive and I don't think it should be doing that and with my brakes I got new brakes on my car for front and back and it's like I never put brakes on because it's still make noise like I need brakes and that's crazy and I don't think that's good and the car seems like it be moving when it's in park.

Driving on the fwy and suddenly all of my hazard lights start turning on at once. My car started to lose power and I had to pull off to the side, not even my emergency lights would work. This is the 2nd time this has happened, the last was a few months ago and had the alternator replaced. Could it be the alternator again? I think not, I have also had issues with my power windows. I am not a mechanic but, I believe there is an electrical problem that is causing a shortage.

Brake lights are either always on, causing traction control to fail, or they are on when the brakes are not applied and off when braking. This also causes cruise control to not work. Anyone driving behind me can not tell when I am braking. Some 2008 G6 models were recalled but for some reason my 2008 G6 has this problem and was not recalled.
