What stands out
Owners have filed 40 lighting complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA lighting complaint has been filed on this vehicle in over 17 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering lighting 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.

The failure pattern owners describe
The overwhelming problem on these 2005 G6s is backwards brake lights—they stay on while driving and turn off when the brake pedal is pressed, the opposite of normal. This happens at random intervals or constantly, confuses other drivers about actual braking, and kills the cruise control since the vehicle sees the brake lights as always engaged. Owners report this malfunction starting anywhere from 30,000 to 138,000 miles and lasting years despite dealer repairs.
GM issued Recall 09V036000 (exterior lighting, brake lamps) and Recall 08317 (fretting corrosion in body control module connector) for this exact symptom, plus a technical service bulletin applying dielectric grease to a connector. Problem is, the recall doesn't cover all VINs and doesn't stick. Owners have had brake light switches replaced, body control modules replaced or repaired, and dielectric compound applied—then the lights fail again within weeks or months. Dealers then refuse further warranty work, claiming the recall is complete.
Some owners report the opposite failure: brake lights don't illuminate when braking, leaving no indication to following traffic. A few also reported a melted fuse box, one with soot residue on a fuse, suggesting an electrical short or overheat condition. One owner had recurrent headlight bulb burn-out and harness melt on the right low-beam. Another had both tail lights fail intermittently despite bulb replacement, drawing police attention. Dealerships are inconsistent—some don't know what repair was performed, some claim the VIN doesn't qualify for recall, and some charge diagnostic fees ranging from $112–$116/hour while denying the issue exists.

Failure modes owners describe
Brake lights stay on when brakes not applied; turn off when brakes are depressed
The brake lights illuminate continuously while driving and extinguish when the brake pedal is pressed—the opposite of normal operation. This occurs intermittently or constantly and confuses other drivers who cannot tell when the vehicle is actually braking. The reverse logic disrupts cruise control, which will not engage while brake lights are on.
When: Between 30,000 and 138,000 miles; onset varies from weeks after recall repair to years into ownership
Symptoms owners cite: Brake lights on while driving without brake application; Brake lights turn off when brakes are depressed; Intermittent or constant reverse operation; Cruise control cannot engage; Difficult to shift from Park; Excessive brake pedal force required
Repairs/costs cited: Dealers replaced brake pedal position sensor, brake light switch, or applied dielectric lubricant to connector per TSB. Many owners report repeat failures after these repairs or recalls. One dealer charged $116 diagnostic fee; another charged $112/hour labor rate. Some dealers denied the issue qualified for recall coverage based on VIN or manufacture date.
Recalls/TSBs owners mention: GM Recall 09V036000 (Exterior Lighting: Brake Lights) and Recall 08317 (fretting corrosion in body control module wiring connector); TSB 08-08-82-001B applied dielectric lubricant to C2 connector. Many owners report the recall either did not fix the problem or was not applied to their VIN despite identical symptoms. Some dealers refused to repair or conduct further diagnostics. One owner reported BCM replacement was required but the dealer charged a fee GM did not cover under recall.
Brake lights fail to illuminate when brakes are applied
The brake lights do not come on when the brake pedal is depressed, creating a serious safety hazard. Other drivers cannot see brake indication. Sometimes there is a brief delay or the lights work only after the brakes are released.
When: Reported between 50,000 and 123,000 miles
Symptoms owners cite: Brake lights do not illuminate when brake pedal is pressed; No brake light indication to other drivers; Intermittent failure; Lights may work only after brakes are released
Repairs/costs cited: Mechanics advised body control module replacement. One complaint mentioned a short in the wiring was found by the dealer after brake light switch replacement did not fix the issue.
Recalls/TSBs owners mention: Recall 09V036000 referenced by owners; some dealers said vehicle VIN was not included in recall. No documented manufacturer assistance in these narratives.
Right rear brake light and signal light malfunction
The right rear brake light flickers or fails to work steadily; the signal light may blink once or twice and then fail. Owner replaced bulbs and wiring harness without success.
When: Three months of intermittent operation reported at time of complaint
Symptoms owners cite: Right rear brake light does not illuminate properly; Right turn signal blinks once or twice then stops; Intermittent operation
Repairs/costs cited: Owner changed bulbs and purchased new wiring harness; mechanic suspected brake light control module failure.
Recalls/TSBs owners mention: Recall coverage mentioned by owner; dealer performed recall (clip retainer replacement per dealer claim) but brake light still did not work afterward.
Brake lights remain illuminated after repair; recurrent failure
Brake lights fail to work correctly, are taken to the dealer and repaired under recall, but the identical problem returns within weeks or months. Dealers then deny further assistance, claiming the recall was already completed.
When: Recurring failures at 72,000–138,000 miles; recurrence 2 weeks to 2 years after initial recall repair
Symptoms owners cite: Brake lights fail to operate properly after recall repair; Same failure mode returns; Intermittent or constant recurrence
Repairs/costs cited: Recall repair (09V036000, 08317, or 14V252000) performed by dealer but failure recurred. Dealers refused further warranty work, stating recall had already been completed.
Recalls/TSBs owners mention: Recalls 09V036000, 08317, 14V252000 completed on vehicle; GM told one owner recall was already completed and would not be repeated. Dealer denied follow-up assistance.
Headlight bulb burns out repeatedly; harness melting
Right side low-beam headlight bulb burns out frequently (owner purchased 5+ bulbs). The bulb harness is melting at the same location, indicating an electrical overheat issue rather than a bulb defect.
When: Recurring on right side; previously occurred once on left side
Symptoms owners cite: Low-beam headlight bulb burns out repeatedly; Bulb harness melts; Right side especially affected
Repairs/costs cited: Owner has replaced bulbs multiple times; underlying harness overheating issue not diagnosed or repaired.
Tail lights stop working; intermittent operation
Both tail lights stop working at the same time. The failure is intermittent—lights may work for a few days, then fail again. One owner pulled over twice by police due to inoperative tail lights.
When: Intermittent, timing not specified by owner
Symptoms owners cite: Both tail lights inoperative; Simultaneous failure of both lights; Intermittent operation—works sometimes, fails other times; Vehicle pulled over by police for non-functioning lights
Repairs/costs cited: Owner noted strong gasoline odor in vehicle; one mechanic suspected fuel pump leak but did not diagnose lighting issue.
Fuse box melting; brake light malfunction
Owner inspected fuse box and found one fuse covered in soot-like residue and a portion of the fuse box physically melted. Brake lights were illuminating without brake application.
When: At 30,815 miles
Symptoms owners cite: Brake lights illuminate without brake pedal applied; Fuse box fuse covered in soot or burn residue; Fuse box partially melted
Repairs/costs cited: Vehicle arranged for dealer diagnosis; status of repair unknown.

Common questions
How serious is the lighting problem on the 2005 Pontiac G6?
It's a documented issue but not catastrophic. 40 complaints have been filed. Repairs average $250 and most owners catch it before it causes a breakdown.
At what mileage does the lighting typically fail?
Across the 35 complaints that reported odometer mileage, most lighting failures cluster between 50,000 and 103,000 miles, with the median around 70,000. A quarter of owners report trouble before 50,000; a quarter make it past 103,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $250 for lighting repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to lighting?
No active recalls currently cover lighting issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
