2021 Chevrolet Bolt electrical system problems

“My 2021 Chevy Bolt keeps showing a battery or power-Propulsion warning light related to the high-voltage system. The warning keeps coming back even after multiple repairs. The first repair was on April 28, 2025, the second was on December 17, 2025, and it is scheduled again for another repair on March 3, 2026. The light is the same every time and affects the car’s performance and reliability. I’m concerned this could be a safety issue involving the battery or propulsion system. The dealer repairs it temporarily, but the warning keeps returning, and the problem has never been fully resolved.”

“Video available and was given to USAA insurance company. This 2021 GM Chevrolet Bolt EV Premier trim vehicle experienced a sudden uncommanded extreme acceleration when I selected "D" (drive) mode on the transmission selector after using "R" (reverse) to back out of a parking lot parking space. The vehicle, despite my stomping and holding the brake pedal down and repeatedly selecting a different mode on the transmission selector, could not be stopped and still wanted to accelerate. The vehicle traveled an estimated 250 feet through a parking lot, crossing a street, hitting the curbs at high speed and through a field. The vehicle stopped against some concrete debris in the field pushing in the bumper slightly but with no airbag deployment. The mishap incident was video recorded and thankfully, there were no passengers or public / private property damages / injuries.”

“The contact owns a 2021 Chevrolet Bolt EV. The contact stated that while driving at 15 MPH, the vehicle failed to stop as needed, and struck a pole. The contact stated that the Forward Collison Avoidance feature failed to stop the vehicle. The contact was unaware of a warning light being illuminated. The vehicle was not towed. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the Forward Collision Avoidance was inoperable. The vehicle was repaired; however, the contact was advised to take the vehicle to a dealer to get the Forward Collision Avoidance system repaired. The dealer was made aware of the failure; however, the contact received no assistance. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 5,000.”

“The contact owns a 2021 Chevrolet Bolt EV. The contact stated while driving approximately 40 MPH, the "Reduced Propulsion Power" warning light illuminated, and a warning chime sounded. The contact was able to drive back to the residence. The contact called a local dealer who advised her not to drive the vehicle and to have the vehicle towed to the dealer. The contact stated that the dealer was unsure if the battery could be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 21V650000 (Electrical System) and stated that the system was to monitor the condition of the battery and related the failure to the safety campaign. The failure mileage was approximately 20,000.”

“I believe the recall remedy gm n21345944 is not sufficient because it dies not monitor the system during the 80-100 % charge. It only allows ip to 80 which is not when it fails. Also it just gives an alert and does not shut down the battery which can allow the fure to happen. According to gm recall 212345940 a new battery was promised. I do not feel safe driving a car which has only been tested up to 80% range when that id not the failure mode. I want a new fixed battery.”

“In nearly exactly the same fashion as Tesla, Chevrolet has reduced my battery range by 15-20% and they don't have any idea when or if they will restore what I've paid for.”
