| Vehicle Speed Control 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.
At random times even while driving: first and most importantly, speed will read 0 mph while driving. Second the following errors will appear on the dash: "steering assist reduced drive with care" "pedestrian friendly alert system" also, the following lights in the dash light brake system warning light service vehicle soon light antilock brake system (abs) warning light service electric parking brake light traction control system (tcs)/stabilitrak light if this happens while driving I have experienced the following: if turning, the steering wheel will jerk because the vehicle loses power steering. If vehicle is in cruise control, the cruise control will disengage and the regenerative braking will quickly slow down the vehicle. I have taken the vehicle to the gm dealership. They had the vehicle in their shop for a month and could not resolve the issue. The last thing they did to the vehicle was a complete reset. This has not resolved the issue and it is happening more frequently now.
