What stands out
Of the 6 model years of Pontiac G6 we track for lighting problems, this one carries the most owner complaints on file — 140.
Owners have filed 140 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.
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
Owners report two main electrical problems in the 2007 Pontiac G6 lighting system.
Brake light malfunction dominates complaints. Owners describe brake lights illuminating while driving without braking, then turning off when the brake pedal is actually pressed—the reverse of normal operation. Some report the lights staying on constantly, others describe intermittent behavior tied to weather (rain/humidity). The problem occurs at all speeds and mileages, though typically surfaces within the first few years of ownership. Owners report near-miss accidents when following drivers cannot see working brake lights during actual braking. Several note cruise control drops out whenever the brake lights stay on, since the vehicle interprets constant brake light illumination as continuous brake application. A handful cite difficulty shifting out of park and brake pedal feel issues (soft pedal, air in line sensation) alongside the lighting problem.
Headlight bulb and socket failures are the second major complaint. Drivers report low-beam bulbs burning out repeatedly—sometimes within days or weeks of replacement. Inspection reveals melted or corroded sockets and wiring harnesses, with burning plastic smell during operation. Some owners replace sockets two or three times before acceptance that the assembly itself may need replacement (dealers quote $200+). A few note passenger-side headlights failing when driver-side is repaired, suggesting a shared electrical issue. Owners document being stopped by police multiple times for out headlights.
Both issues appear traced to electrical connector corrosion by owners and technicians, though root cause remains unconfirmed across the complaint set.

Failure modes owners describe
Brake lights illuminating continuously (reverse operation)
Brake lights remain on while driving without brake application; lights turn off when brake pedal is pressed. Effectively inverts normal brake light function.
When: Typically first years of ownership; occurs at various mileages from ~16k to 225k miles; intermittent or constant
Symptoms owners cite: Brake lights on while accelerating or cruising; Brake lights off when brakes applied; Cruise control disengages or won't engage when lights are on; Problem worse in humid/rainy weather; Difficulty shifting from park (requires excessive brake pedal pressure); Soft brake pedal feel or sensation of air in brake line
Repairs/costs cited: GM Dealership: brake light switch replacement ($100 reported), brake pedal position sensor replacement, dielectric grease application to C-2 connector (temporary fix per owners). Repairs recur within 9-12 months or intermittently. Independent mechanics unable to resolve in some cases.
Recalls/TSBs owners mention: Recall 09V036000 issued for 2005-2006 models only (not 2007). Recall 14V252000 (2014, multi-system) issued later but parts availability problems reported. Some 2007 owners applied recall fix (dielectric grease) with temporary results. GM advised problem not under recall for 2007 models and some dealerships declined diagnosis.
Low-beam headlight bulb failure with socket/connector overheating
Low-beam bulbs burn out repeatedly over short intervals. Inspection reveals melted or severely corroded socket connectors and wiring harness. Burning plastic odor reported. Problem recurs even after socket/harness replacement.
When: Reported from ~40k to 84k miles; some failures recurring for 2+ years of ownership
Symptoms owners cite: Low-beam bulb burns out within days to weeks after replacement; Socket wires and bulb contact area melted or burned; Burning plastic smell when headlights on; Headlight flickers or goes out intermittently while driving; Passenger-side fails after driver-side repair, or vice versa; Tapping/hitting headlight assembly temporarily restores function
Repairs/costs cited: Owner replacements of bulbs (correct type confirmed); aftermarket socket/harness replacements ($250+ cumulative costs reported); full headlight assembly replacement quoted by dealers at $200+. Independent shop diagnosis: melted connector harness, defective socket. Problem persists across multiple replacement attempts.
Recalls/TSBs owners mention: No recall identified by owners. Service bulletin noted by one owner (repair costs owner responsibility). Dealers initially told owners bulbs were defective or problem was owner-caused; no OEM solution offered. One owner reported dealer eventually replaced wire harness, still unresolved.
Intermittent cruise control failure
Cruise control drops out mid-drive at speed or refuses to engage. Owners note this correlates with brake light malfunction; brake lights remaining on prevents cruise engagement.
When: Occurs concurrently with brake light issues; mileages 40k–105k
Symptoms owners cite: Cruise control disengages unexpectedly while active; Cruise will not set or engage; Cruise won't work when brake lights are illuminated
Repairs/costs cited: No independent repairs documented; owners assume electrical root cause tied to brake light circuit
Recalls/TSBs owners mention: No mention of OEM remedy specific to cruise control; treated as secondary symptom of brake light electrical issue
Electronic Stability Control / Traction control warning light malfunction
Stability control and traction control warning lights illuminate intermittently without driver activation or actual traction loss. Lights come on and off randomly.
When: Reported at ~22k miles; intermittent over time
Symptoms owners cite: Traction control light on when system is off; Stability control light flashing with error message; Lights come on/off in random sequence with ABS and check engine lights
Repairs/costs cited: One owner reported service bulletin indicated oil control solenoid module (not BCM) as separate issue, owner responsible for cost. Scanner shows no codes stored.
Recalls/TSBs owners mention: BCM (body control module) recall mentioned; one owner noted repair costs despite recall notification of body control module defect. Parts availability issues reported for recall repairs.

Common questions
How serious is the lighting problem on the 2007 Pontiac G6?
It's a documented issue but not catastrophic. 140 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 113 complaints that reported odometer mileage, most lighting failures cluster between 50,000 and 105,000 miles, with the median around 75,000. A quarter of owners report trouble before 50,000; a quarter make it past 105,000. 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.
