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…

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…

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.
