What owners say about the service brakes

Verbatim from NHTSA complaints, newest first
“Problem with completed recall 14V252000. Symptoms have returned. In some vehicles, increased resistance in the Body Control Module (BCM) connection can cause voltage fluctuations in the Brake Apply Sensor (BAS) circuit. This may lead to: Brake lights illuminating without the brake pedal being pressed Brake lights not illuminating when the pedal is pressed Difficulty disengaging cruise control Gear shifter not moving out of PARK without the brake pedal pressed Disablement of crash avoidance features such as traction control, electronic stability control (ESC), and panic braking assist ARFC ARFC +1 These failures increase the risk of a crash”

“The contact owns a 2008 Pontiac G6. The contact stated that while her fiancé’ was driving behind her, he notified her that her rear driver’s and passenger’s side brake lights remained illuminated while the accelerator pedal was depressed. No warning lights were illuminated. The vehicle was taken to an independent mechanic where the rear passenger’s and driver’s side brake light bulbs were replaced; however, the failure recurred. The contact then received notification of the NHTSA Campaign Number 14V252000 (Electrical system, Exterior Lighting, Vehicle Speed Control, Electrical Stability Control). Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 159,000.”

“BRAKE LIGHTS STAY ON WHILE DRIVING AND GO OFF ONCE BRAKE PEDAL IS PUSHED. THIS WAS A RECALL DONE SEVERAL YEARS AGO BUT IN 2019 WE ARE HAVING THE SAME ISSUE AFTER THE RECALL WAS PREVIOUSLY PERFORMED. ADDITIONALLY, I HAVE HAD THIS PROBLEM REPEATEDLY SINCE I BOUGHT THE VEHICLE IN 2011, AND IT HAS BEEN REPAIRED MULTIPLE TIMES AND BY MECHANICS OTHER THAN THE RECALL. THE MOST RECENT REPAIR WAS IN NOVEMBER OF 2019. YESTERDAY, THE PROBLEM RETURNED (IF IT HAD EVER GONE AWAY TO BEGIN WITH.) THE MECHANICS ARE TRYING THEIR BEST TO GET TO THE BOTTOM OF THE PROBLEM; HOWEVER, THE BEST I HAVE EVER GOTTEN IS ABOUT 8 MONTHS WITHOUT NOTICING ANY ISSUES. WHEN YOU BUY A CAR--NEW OR USED--YOU EXPECT THE BREAK LIGHTS TO WORK AS THEY ARE DESIGNED TO WORK FOR THE LIFE OF THE VEHICLE. NOBODY BUYS A CAR EXPECTING TO HAVE TO DEAL WITH THE UNCERTAINTY OF NOT KNOWING WHETHER YOUR CAR IS ACTUALLY ALERTING DRIVERS THAT YOU ARE STOPPING WHEN YOU ARE IN BUSY TRAFFIC.”

“BRAKE LIGHTS STAY ON WHILE DRIVING AND GO OFF ONCE BRAKE PEDAL IS PUSHED. THIS WAS A RECALL DONE IN 2014 BUT IN 2019 WE ARE HAVING THE SAME ISSUE AFTER THE RECALL WAS PREVIOUSLY PERFORMED. THIS ISSUE IS ALSO CAUSING THE CRUISE CONTROL TO NOT WORK, AND THE SERVICE TRACTION LIGHT TO COME ON.”
