EXTERIOR LIGHTING10/20/2025
The contact owns a 2011 Chevrolet Volt. The contact stated that water was accumulating inside the driver's side taillight assembly. The contact stated that the water caused a short circuit in the taillight, and the passenger’s side turn signal became inoperable. The contact had taken the vehicle to an independent mechanic where it was diagnosed, and determined that the wiring harness for the driver's side taillight assembly needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 97,000.
SERVICE BRAKEScrash08/04/2025
I was stopped at a red light with my foot on the brake. When the light turned green, I released the brake and the car suddenly accelerated forward on its own, without me touching the accelerator. As soon as the car surged forward, I immediately pressed the brake pedal hard to stop it but instead of slowing down, the car continued to accelerate. It felt like pressing the brake was making it worse. The car was totally out of my control. The vehicle collided with tow truck and even after the impact, the engine was still revving as if it was trying to keep going. I had to shut the car off to stop it completely. There were no warning lights or error messages before or during the malfunction. The front end of my car was damaged in the crash. No one was injured, but the malfunction could have easily caused serious harm or death. This was not user error it was a terrifying mechanical and electronic failure. The car accelerated on its own and the brakes failed or possibly triggered more acceleration. I have never experienced anything like this. After looking online, I found other Volt owners reporting similar problems involving brake assist failure, unintended acceleration, and stuck revving. This looks like a serious pattern that deserves urgent attention. I’m asking the National Highway Traffic Safety Administration (NHTSA) and General Motors to immediately investigate this issue. I want to know if there are any recalls, technical service bulletins (TSBs), or known defects related to brake failure or unintended acceleration in the 2011 Chevy Volt. Please contact me with next steps. This is a major safety risk that could easily result in fatalities if not addressed.

'11 Chevy Volt hybrid was daily driver of 100+ miles, multiple trips both highway and city for last 2 1/2 months. Breaks and rotors have been replaced all the way around, fresh oil changes as needed and filters. Warning on dash "Service High Voltage Charging System", ”Service Airbag" and check engine light have been on since I've owned it (Oct. 23). When plug car in it doesn't charge, but the EV charges while driving. Car generally switches back and forth from EV to ICE without issues. No other issues have been noted. 1/18/24 Start car and drive all day for work. Total of 129 miles between 22 trips. Last trip car sat for 30 minutes after running deliveries all day. Started as normal, turned off at gas station, filled tank with premium, restarted and drive to freeway. Drove 20 miles, pulled over to text, put car in park. 5 mins later took out of park and car wouldn't move. Inside had complete power, radio, windows, ect. Only noticable difference was car would get no acceleration, power steering went out, and heat started blowing cooler air. Absolutely no warning and car just cuts off engines. Thankfully I was parked safe. Towed home, replaced 12v. Started and drove no problem on 1/19/24. No new warnings or anything different. Started up 1/20/24 drove 7 miles and the engines cut off in the middle of a main road while accelerating, once again no warning. Luckily got into turn lane before almost getting hit. Still not sure what's wrong with car. Same codes. No battery warning or loss of power indication at all. Just up and cuts off. This is very very dangerous and needs to be looked into please. When my volt died today the truck behind me had to slam on his brakes and came inches from hitting me. If this would've happen on the freeway, I'd likely been hit.
FUEL/PROPULSION SYSTEM12/29/2023
The car quit running when my wife was driving the car when the mileage range went down to 4 miles range remaining. The car was towed to the local Chevrolet dealership who charged over $1,000 to reset the electronics so car would run. I was advised that if battery range was run down to a low mileage range that car would quit running again and that it would have to be towed back to the dealership for the electronics to be reset. I was concerned about liability if anyone drove car and it stopped on highway. It was clear to me that the only way out of potential liability, associated with the car stopping on the highway was to sell the car for salvage. I purchased this Chevrolet Volt Premier new. It was never in a collision or damaged in any way. The car was sold for with approximately 81,000 miles for $2,013.

Several times over the 2 years I have owned this vehicle while driving an almost complete loss of braking occurs with a service notice for the ABS system. If you turn off the ignition and restart it the braking works fine. I am in the process of having the Electronic Brake Control Module - GM (84070136) and the Brake Pressure Modulator Valve - GM (23283683) replaced. i believe that there is a design flaw in this system in that a problem of the ABS should not eliminating the ability to stop the vehicle. This is costing me $3500, but the point is that loss of braking is a serious safety issue and should be addressed by the manufacturer. Thank you.

SINCE THE SPRING OF 2020, "SERVICE AIR BAG" WARNING COMES ON INTERMITTENTLY, RELATED TO PASSENGER SEAT AIRBAG. WARNING GENERALLY COMES ON AT STARTUP, IF IT APPEARS. NO FLUIDS HAVE BEEN SPILLED ON THE SEAT, AND NO VISIBLE DAMAGE TO THE SEAT. I AM THE SECOND OWNER, PURCHASED FROM FRIEND, CAR HAS ALWAYS BEEN GARAGED AND SERVICED REGULARLY. ONLINE SEARCH SUGGESTS THAT OTHER OWNERS HAVE SAME ISSUE, AND THAT DIAGNOSIS AND REPAIR CAN BE $500 TO $1000. I HAVE NOT HAD A CHEVROLET DEALER DIAGNOSE THIS ISSUE SINCE IT IS INTERMITTENT. CURRENT MARKET VALUE OF VEHICLE (55K MILES, OTHERWISE EXCELLENT CONDITION, A GREAT CAR TO DRIVE) MAKES COST OF REPAIR DIFFICULT TO JUSTIFY, ESPECIALLY IF IT COULD HAPPEN AGAIN WITHOUT WARNING.
