Filed Sep 15, 2026 · Brakes, Electrical · IL

Problem with completed recall 14V252000. Symptoms have returned. In some vehicles, increased resistance in the Body Control Module (BCM) connection can cause voltage fluctuations in the Brake Apply Sensor (BAS) circuit. This may lead to: Brake lights illuminating without the brake pedal being pressed Brake lights not illuminating when the pedal is pressed Difficulty disengaging cruise control Gear shifter not moving out of PARK without the brake pedal pressed Disablement of crash avoidance features such as traction control, electronic stability control (ESC), and panic braking assist ARFC ARFC +1 These failures increase the risk of a crash

Brake lights stay on while driving and go off once brake pedal is pushed. This was a recall done in 2014 but in 2019 we are having the same issue after the recall was previously performed. This issue is also causing the cruise control to not work, and the service traction light to come on.

Takara recall I was on my way to a store driving and my car started shaking and so I got of the interstate and it starting acting like it was losing power so I pulled over shut it of for a hr and turned it back on tried to go in reverse nothing happened tried to go in drive nothing happened it didnt yo anywhere so I put 2 quarts of transmission fluid in it then it would go in drive but no reverse. I brought it to a garage and a ton of codes came up they cleared it and told me not to worrie about it but it smelt weird and I new something was wrong.I believe it has something to do with the transmission cables and a throttle sensor because it was acting like it wanted to go fast n the throttle would accelerate when I didnt push more on the paddle kinda like it was stuck in cruise control but even when I press the brakes it still rev.

My air bags don't work in my car. My car was kept outside all these years. My cruise control doesn't work at all and my volume for the radio and illumination of the steering wheel doesn't work. I never owned a car that had issues with an airbag. I'd be willing to speak to the media and tv personnel.

I have not been able to use the cruise control on my 2008 pontiac g6 gt. I am having steering issues where my steering wheel clicks. Plus my air bag light is on all the time. I called customer service through pontiac they gave me a reference number.8-3680048435. I asked for the corporate office to speak to someone at gm about my car being missed on a recall and no corporate person was given.

My 08 pontiac g6 is having difficulties with the breaking, traction, and cruise control. My break lights are staying on all the time even when my break pedal is not pressed and my traction control is shutting off as soon as I start up my car as well as my cruise control picks and chooses when it is going to work and when it does work it is not disengaging properly.

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.

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.

Bought a used 2008 pontiac g6 one week ago. It had an open recall--13036. This was a brake lamp malfunction which could also affect the electronic stability control and traction control (disabling them). Also possible problems were brake lights coming on when accelerating and going off when braking. This also affects the cruise control and the shifter. Had the recall work done today, october 3, 2014. By the time I got home, brake lights were continuously on, cruise control did not work, and traction control and ESC were disabled. This after gm's recall.
