Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.
full bulletin at NHTSA ↗This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.
full bulletin at NHTSA ↗16188 Special Coverage. Some vehicles may have a condition where increased resistance in the body control module (BCM) connection system can result in voltage fluctuations or intermittency in the brake apply sensor (BAS) circuit that can cause brake lamp malfunction. Specifically, the brake lamps may either illuminate without the brake pedal applied, or turn off when the pedal is applied. If this condition occurs within the stated terms, dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to the BCM X2 (C2) connector and the BAS harness connector, and relearn the brake pedal home position. The repairs will be made at no charge to the customer.

The failure pattern owners describe
The 2007 Pontiac G6 has a critical, pervasive electrical fault that causes brake lights to malfunction in a backwards manner: they illuminate during normal driving but extinguish when the brake pedal is pressed. Police officers and other drivers have repeatedly told owners their brake lights are on when the car is moving, then off when actually stopping—creating a serious safety hazard since following vehicles cannot determine braking intent.
Owners report the problem strikes between 2–3 years of ownership and recurs throughout the vehicle's life. Cruise control fails to engage or disengages unexpectedly when the fault occurs. Dealers have performed temporary fixes—applying electrical grease to body control module connections and using zip ties—that last three weeks to three months before the problem returns. One owner had the brake pedal position sensor replaced; another had a circuit board replaced twice, both without permanent resolution.
GM issued recall 14V252000 starting in 2014 for 2005–2006 models and some 2007 vehicles, but many 2007 owners find their VINs excluded despite identical failures. Those included in the recall report the fix failed within months to a year. Owners also report failed brake calipers locking up suddenly during highway driving without pedal input, violent rotor warping and vibration as early as 19,000 miles, and requiring excessive brake pedal pressure to shift out of Park. The underlying electrical fault in the brake apply sensor circuit causes ripple failures across traction control, stability control, and shift interlock systems.

Failure modes owners describe
Brake lights illuminating in reverse (on while driving, off when braking)
The brake lights come on during normal driving or acceleration, then extinguish when the brake pedal is depressed. This inverted behavior creates a critical safety hazard, as following drivers cannot determine actual braking status.
When: Intermittently across the vehicle's lifespan; owners report it starting between 2-3 years of ownership and recurring throughout ownership
Symptoms owners cite: Brake lights stay on while driving at various speeds; Brake lights go off when brake pedal is pressed; Cruise control disengages when lights malfunction; Other drivers report seeing brake lights on continuously, then off when vehicle actually stops; Pattern repeats unpredictably, sometimes multiple times per drive
Codes mentioned: BCM (Body Control Module) voltage fluctuations in BAS circuit, Brake Apply Sensor (BAS) circuit intermittency, Brake Pedal Position Sensor reading errors
Repairs/costs cited: Owners cite temporary fixes: dealer 'calibration' of the system lasts 3-6 weeks before recurrence; brake pedal position sensor replacement unsuccessful; electrical grease applied to BCM connectors provides only days of relief; replaced circuit board twice with no permanent resolution
Recalls/TSBs owners mention: NHTSA Campaign 14V252000 and 09V036000 partial recalls issued for 2005-2006 and some 2007 models; repair consisted of applying dielectric grease and using zip ties (described as 'band-aid' fix); special coverage adjustment offered but expired; some vehicles not included in recall VINs despite identical failures; GM claimed warranty letters were mailed but many owners never received them
Brake lights malfunction—failure to illuminate when braking
Brake lights either fail to illuminate entirely or illuminate only intermittently when the brake pedal is depressed. This creates a serious safety hazard by preventing following drivers from knowing the vehicle is braking.
When: 30,000 to 160,000 miles; some failures early in ownership (19,000-30,000 miles)
Symptoms owners cite: Brake lights do not turn on when braking; Brake lights remain off even with hard brake application; Intermittent illumination—lights work sometimes, fail to work other times; Lights stay on when vehicle is parked but ignition is on
Codes mentioned: Brake stop light switch failure, BAS (Brake Apply Sensor) circuit malfunction, Brake light bulb failure (though replacement does not resolve issue in many cases)
Repairs/costs cited: Owners replaced brake light switch 3-4 times without permanent resolution; replaced both rear brake light bulbs multiple times; dealers unable to diagnose root cause on multiple occasions; some repairs performed under warranty but failures recurred out of warranty
Recalls/TSBs owners mention: NHTSA Campaign 14V252000 recall issued; some recall parts unavailable or delayed; recall remedy (BCM connection service) failed to repair vehicle in multiple documented cases; failures recurred intermittently after recall repair; technical service bulletin NHTSA item 10032206 issued for brake light switches but did not resolve issue
Brake caliper locking without driver input
The right front brake caliper locks up suddenly without the driver applying brakes, causing the vehicle to decelerate abruptly. Smoke is reported from the locked wheel; the condition occurs multiple times, particularly after cruise control engagement on highways.
When: Failure mileage 106,202; occurred 6 times over vehicle's ownership, 4 times on highway shortly after cruise control engaged
Symptoms owners cite: Caliper locks in place without brake pedal application; Vehicle slows rapidly and front end shakes violently; Smoke comes from wheel; Occurs at highway speeds and in-town driving; Clusters around cruise control engagement
Codes mentioned: Brake switch failure (dealer diagnosis)
Repairs/costs cited: Dealer diagnosed brake switch failure; caliper remained locked after stopping; smoke generation indicates overheating from friction
Recalls/TSBs owners mention: Pontiac paid for diagnostic only; did not pay for repairs; failure attributed to related recall but no coverage provided
Brake rotor warping and premature wear
Rotors warp due to excessive heat at relatively low mileages, causing violent vibration during braking. Brake shop reported this is a frequent problem on G6 vehicles, occurring every 14,000–19,000 miles. Tires wear prematurely as well.
When: 19,000 to 32,200 miles; one case at 32,900 miles
Symptoms owners cite: Violent vibration when braking at highway speeds; Rotors warped from excessive heat; Premature tire wear; Rotors need turning and will require replacement at next service; ABS light illumination noted in some cases
Codes mentioned: ABS (Anti-lock Braking System) diagnostic codes (owner replaced wheel bearing after ABS light; ABS light came back on after ECM replacement)
Repairs/costs cited: Rotors turned and pads replaced; brake shop advised vented-style rotors would help with cooling; replacements performed under warranty in one case; owners cite internet forum evidence of frequent rotor failure on G6 models
Recalls/TSBs owners mention: Warranty repairs performed; no recall or service bulletin issued specifically for rotor design; GM advised non-OEM rotors may resolve recurring problem
Difficult or impossible brake pedal travel to shift out of Park
The driver must depress the brake pedal unusually hard—sometimes with excessive force—to shift the vehicle out of Park. In some cases, the pedal vibrates when being pressed to disengage from Park.
When: Occurs intermittently during vehicle operation; one case at 112,000 miles
Symptoms owners cite: Requires forceful or excessive brake pedal depression to shift out of Park; Brake pedal vibrates when disengaging from Park; Difficulty or inability to move shift lever from Park position; Sometimes works normally, sometimes requires extreme pressure
Codes mentioned: BCM (Body Control Module) malfunction affecting shift interlock, BAS (Brake Apply Sensor) circuit voltage fluctuations
Repairs/costs cited: Not directly repaired in complaints; related to broader BCM/BAS circuit issues
Recalls/TSBs owners mention: GM recall 14V252000 addressed BCM connection resistance; vehicle was not repaired despite recall notification in one case
Cruise control failure to engage or disengage
Cruise control will not engage, or engages but then disengages unexpectedly. In some cases, additional brake pedal travel is required to disengage cruise control once engaged.
When: Intermittent failures across ownership; some failures in 2012 onward
Symptoms owners cite: Cruise control will not set or activate; Cruise control disengages without driver input; Cruise control engages for only a few seconds before disengaging; Requires additional brake pedal travel to disengage cruise control; Appears linked to brake light malfunction events
Codes mentioned: BAS (Brake Apply Sensor) circuit intermittency preventing cruise control engagement
Repairs/costs cited: No specific repairs documented; issue resolved temporarily when brake light problem was addressed, but recurred
Recalls/TSBs owners mention: GM recall 14V252000 stated cruise control failure as a secondary effect of BAS circuit malfunction; some owners noted cruise control remained non-functional even after recall repair
Traction control and electronic stability control disabled or malfunctioning
Traction control and electronic stability control systems become disabled, and associated warning lights illuminate. In one case, complete brake failure occurred alongside traction control light illumination.
When: Intermittent; one case at 55,000 miles involving collision
Symptoms owners cite: Traction control light illumination; ESC (Electronic Stability Control) light illumination; Traction control disabled during operation; Electronic stability control disabled; In one case: complete brake failure with traction control light on simultaneously
Codes mentioned: BCM (Body Control Module) voltage fluctuations affecting multiple systems, ABS system malfunction
Repairs/costs cited: One owner's vehicle involved in collision when brakes failed entirely; GM sent engineer to examine event data recorder but refused to share findings (claimed proprietary data); some owners replaced rotors with non-OEM parts attempting to resolve brake issues
Recalls/TSBs owners mention: GM refused to repair vehicle that had complete brake failure; claimed engineer investigation was internal proprietary information; no recall coverage for this severity of failure in complaints reviewed
