One problem related to brakes failed has been reported for the 2018 Chevrolet Volt. The most recently reported issues are listed below.
Collision occurred on e denny way in seattle, approx 3:20 pm on a downhill slope in stop-and-go traffic after about 20 minutes of constant brake use to hold back the car. About 2/3 of the way downhill the brakes failed, no resistance whatsoever and the car rolled into the vehicle in front, a distance of about 15 feet. This was a one-off incident and did not recur so far. Gm and 3rd party inspectors found no error codes, but the brakes indeed failed, which makes me suspect a design problem in the brake-by-wire system that controls the pedal pressure and modulated regenerative braking. It was like sliding on ice, no traction whatsoever.
