What stands out
Owners have filed 134 electrical 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.
Electrical accounts for 19% of all owner complaints filed against this vehicle, across 11 categories tracked.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical 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 communication provides information to the technician about vehicles that have an intermittent no crank, no start, or start stall concern with the security light coming on. Technician may find Diagnostic Trouble Codes B3055, B3060, and/or B3935. Technician should not replace any parts for this concern. If unable to duplicate the concern ask if the customer uses any Radio Frequency Identification Devices when the concern is present. Dealer should also direct their customers to the appropriate section in the Owner manuals that references that the device complies.
full bulletin at NHTSA ↗Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

The failure pattern owners describe
The 2009 Pontiac G6 has a pattern of serious electrical failures that recur despite repairs and recall attempts. Most common is the brake light inversion: lights stay on during normal driving and turn off when you press the brake pedal—the exact opposite of correct function. This makes following drivers unable to see when you're actually braking. Owners also report cruise control becoming inoperative when this happens.
Low-beam headlights fail chronically. Owners replace bulbs every 2–4 weeks; the connectors and wiring sockets melt or char from excessive current. One owner replaced headlight parts 20 times. Mechanics at GM dealerships acknowledge this as a "known defect," yet no recall was issued. Wiring has been observed smoking, and owners fear fire risk.
Door locks malfunction randomly—locking open so doors won't close, or locking shut trapping occupants inside. Locks reset when parked, making dealership diagnosis impossible. One mechanic got trapped in a G6. GM refuses recall coverage, quoting $300–$400 per door.
Tail lights fail, fuses blow repeatedly, and the battery or ignition can suddenly cut power. Interior lights stay on endlessly. On one recent purchase, the dealer installed the battery backward, nearly causing fire.
Multiple owners report experiencing seven or more distinct electrical failures simultaneously. Despite repairs and one major recall (GM #13036 / NHTSA 14V252000), problems recur within weeks to months. Owners describe the vehicle as unsafe for night driving and unable to be permanently fixed by dealership service.

Symptoms owners cite: Brake lights stay on during normal driving without braking; Brake lights turn off when brake pedal is depressed; Cruise control becomes inoperative when brake light malfunction occurs; Service traction control light illuminates intermittently; Check engine warning lights appear; ESC and panic brake assist features malfunction; E.S.C. and TCS warning lights randomly flash and flicker
Codes mentioned: NHTSA Campaign 14V252000, GM Recall 13036
Repairs/costs cited: Owners report BCM connector cleaning with dielectric grease as temporary fix; dealership repairs include brake pedal position sensor replacement (~$300 diagnostic fee); issue recurs after 14 months in at least one case; full harness replacement may be required (~$290–$400 per door lock, owners report)
Recalls/TSBs owners mention: GM Recall 13036 / NHTSA Campaign 14V252000 issued July 2014 for electrical system and brake light issues; owners report GM initially refusing warranty coverage or requiring dealership service at owner's cost; tech service bulletin exists describing the maintenance procedure
Low-beam headlight failure with burned/melted sockets and wiring
Low-beam headlights fail intermittently or permanently; bulbs burn out within weeks; wiring connectors and sockets overheat, melt, or char. Issue appears to stem from excessive electrical current to the bulbs.

Recalls/TSBs owners mention: Mechanics at GM dealerships acknowledge 'known defect' per independent mechanic referral (narrative #3); one auto-parts employee reported dealership sees 6–10 cars weekly with this problem; no recall issued for headlight wiring despite widespread complaints online; GM stated the issue does not affect the whole vehicle and refused extended warranty coverage
Door lock malfunction—locks engage/disengage randomly or jam

I have replaced 6 bulbs both driver and passenger side low beam lights I thought they were blown but come to find out they short because they are melting. I have replaced the wiring and the headlight sockets just for them to melt again. I have called chevorlet and gm motors to see why this isn't a safety issue???

Common questions
How serious is the electrical problem on the 2009 Pontiac G6?
It's a documented issue but not catastrophic. 134 complaints have been filed. Repairs average $850 and most owners catch it before it causes a breakdown.
At what mileage does the electrical typically fail?
Across the 106 complaints that reported odometer mileage, most electrical failures cluster between 50,000 and 95,000 miles, with the median around 70,000. A quarter of owners report trouble before 50,000; a quarter make it past 95,000. 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 $850 for electrical 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 electrical?
No active recalls currently cover electrical 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.
