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 most common complaint across these 24 narratives is a brake light malfunction where lights illuminate without brake pedal input and fail to illuminate when brakes are applied—sometimes called inverted logic. This happens randomly or intermittently, occasionally triggered by heavy rain. Multiple owners state the condition forces them to pump the brake pedal before shutting the car off to prevent battery drain, and several report other motorists alerting them to always-on brake lights during normal driving.
Dealers and owners trace this to the body control module (BCM) connectors developing high resistance and the brake pedal position (BPP) sensor failing. NHTSA Recall 14V252000 was issued to address this electrical control issue, but some owners say their dealerships initially claimed no recall applied to their vehicle. Repair attempts included replacing the brake light switch, resealing the sensor, cleaning and lubricating BCM connectors, and resetting the BPP sensor—yet the problem recurred in several cases. The BCM itself required replacement at a cost cited as $800 in one case; some owners report the recall part was unavailable when they sought repair.
The malfunction often triggers unexpected cruise control disengagement and illuminates service traction, service ABS, and stability control warnings. Owners describe this as frightening when it occurs at highway speeds in darkness.
A secondary complaint involves brake squeal or squeak at low mileage; dealership rotor resurfacing did not eliminate it. One owner also reports front rotor warping that returns within 8,000 miles even after replacement with new rotors, suggesting a design or manufacturing issue rather than a parts defect.

Failure modes owners describe
Brake lights illuminating when brakes not applied, or failing to illuminate when brakes applied (inverted logic)
Brake lights turn on without brake pedal engagement and fail to illuminate when brakes are depressed. Often accompanied by cruise control disengaging unexpectedly. Owners report this occurs randomly or intermittently, sometimes correlated with rain. The root cause is traced to BCM (body control module) connector resistance issues and brake pedal position (BPP) sensor malfunction.
When: Reported from 26,000 miles through 104,000 miles; some owners cite recurrence over multiple years (2013-2015 and beyond)
Symptoms owners cite: Brake lights on continuously when not braking; Brake lights off when brakes applied; Cruise control disengages when brake lights malfunction; Condition occurs randomly or intermittently, sometimes triggered by rain; Service traction, service ABS, and traction control warnings may illuminate; Cruise control activates or deactivates on its own
Codes mentioned: NHTSA Campaign 14V252000 (Electrical System, Electronic Stability Control, Exterior Lighting, Service Brakes Hydraulic, Vehicle Speed Control)
Repairs/costs cited: Dealers have replaced brake light switches, resealed sensor casings, cleaned and lubricated BCM connectors, reset BPP sensor, and in some cases replaced entire BCM at cost cited as $800. Some repairs were temporary; problem recurred. One report of BCM shorting out requiring replacement per recall.
Recalls/TSBs owners mention: NHTSA Recall Campaign 14V252000 issued. Some owners received recall notices but dealers initially claimed no recall existed for their VINs. Some vehicles covered under recall; parts reported unavailable at time of repair attempts. BCM replacement under recall; initial recall repair (switch replacement) was inadequate and did not resolve underlying issue.
Brake squeal/squeak
Brakes produce loud squealing or squeaking noise when applied. Owners report mechanics attributed noise to dust, but owners dispute this and express concern about brake safety. Dealer resurfacing of rotors did not resolve the issue. Manufacturer could not identify mechanical failure and declined to assist.
When: Reported on new vehicle at low mileage (26,000-34,790 miles reported); did not occur during test drive
Symptoms owners cite: Audible squeaking or squealing when brakes applied; Noise continues despite rotor resurfacing; Owner concern about brake failure risk
Repairs/costs cited: Rotors resurfaced twice by dealership without resolution. No mechanical failure identified by technicians.
Recalls/TSBs owners mention: Manufacturer stated they could not assist if no mechanical failure found.
Front rotor warping with vibration
Front rotors warp repeatedly even after resurfacing or replacement, causing front-end vibration. Owner reports this is a design or manufacturing defect, not a parts issue, as problem recurred with new rotors after only 8,000 miles.
When: Warping occurred again 8,000 miles after previous resurfacing
Symptoms owners cite: Front-end shake while braking; Front rotors warp repeatedly
Repairs/costs cited: Rotors cut/resurfaced multiple times, then replaced with new rotors; warping recurred within 8,000 miles with new parts, suggesting design defect.

Common questions
How serious is the brakes problem on the 2009 Pontiac G6?
It's a documented issue but not catastrophic. 24 complaints have been filed. Repairs average $450 and most owners catch it before it causes a breakdown.
At what mileage does the brakes typically fail?
Across the 19 complaints that reported odometer mileage, most brakes failures cluster between 43,888 and 79,000 miles, with the median around 66,000. A quarter of owners report trouble before 43,888; a quarter make it past 79,000. 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 $450 for brakes 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 brakes?
No active recalls currently cover brakes 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.
