Car will unexpectedly accelerate when car is coming to a stop. Almost causing a crash a few times. (cruse control is not on).
The vehicle was driving and lost all power and came to a stop. After about 5 seconds vehicle regained power. The "check engine light" illuminated on the dash. Took to dealer and stated could not replicate problem. Only have the report from vehicle computer and the ev technician did not understand the information and had to call gm for help. Got car back and problem happen again. Dealer had gm specialist out to help. Gm reset computer and problem just happens again.
I own a 2023 chevy Bolt Ev. Around 9/27/24 at 5,144 miles, the vehicle began experiencing serious electrical and propulsion issues. It has been to the dealership six times, each requiring a tow due to total loss of function. Issues include blown fuses, charging failures, shifting problems, propulsion loss, and repeated warning messages. Repairs have involved fuse box replacements, a new wiring harness, and other electrical components. The car has spent over 100 hours inactive at the dealership. Problems have been confirmed by technicians, but persist despite repairs. Additional safety concerns include a defective impact sensor, airbag warning lights, and a burned-out headlamp. These compromise crash readiness and visibility. Due to ongoing issues, the vehicle has been parked and unused for months, as it is unsafe and unreliable to drive. The manufacturer has not inspected the vehicle. Based on repeated failures and unresolved safety risks, I believe this vehicle qualifies as a lemon and request further investigation.
The vehicle suffers from severe, unresolvable electrical failures causing recurring loss of propulsion, shifting lockouts ("no driving conditions" / stuck in park), complete exterior lighting failures, and loss of communication with the restraints control module (rcm) and airbag impact sensors. The primary failure involves short circuits, open circuits, poor terminal contact, and thermal damage with melted, charred wiring and exposed copper in the main harness[cite: 6]. On may 25, 2026, onstar telematics issued a critical red alert for the regenerative braking system[cite: 7]. All damaged components and diagnostic reports are available for inspection upon request[cite: 6, 7]. Safety risks include sudden loss of propulsion at highway speeds, total headlight and tail light loss during night driving, and potential non-deployment or malfunction of airbag restraint systems during a collision. The issues have been repeatedly reproduced and confirmed by an authorized dealership through 7 repair attempts between sept 2024 and Apr 2025. Diagnostic steps included opening gm tac case 9-13634782861, consulting gm engineers, and testing 33 ground points. On oct 28, 2024, the dealer and an insurance adjuster officially confirmed the failures are covered under gm warranty and unrelated to any accident[cite: 8]. Symptoms first appeared on sept 10, 2024 (at 5,144 miles) with a "waiting initialization to shift" message, blown fuse 58, and loss of power to the ecm. Warning signs prior to subsequent failures included "service trans" warnings, "reduced propulsion" alerts, dim headlights, check engine lights, srs/airbag warning lights, and total shifting lockouts after hitting road bumps. Despite replacing fuse 58 (multiple times), fuse 64, ip fuse 7, the underhood fuse block, ecm connector terminals, headlamp assemblies, the rcm module, and multiple airbag impact sensors, the underlying electrical instability remains unresolved.
Twice now within three months while I was backing up as I was parking the car parallel to the curb, the car suddenly accelerated at a much faster pace and projected the car backwards. Luckily no property or individuals were hurt. It would appear that the accelerator or speed control failed at the lower speeds required when backing up to parallel park. I saw no warning lights on the dash however may have been looking back as I was parking. The dealer did not find any code to indicate a system failure. They suggested that we removed the after-market mats.
Electronic drive unit fault, auxilary transmission pump needs to be replaced. It’s a brand new vehicle and this is a very common problem.
Sudden rapid acceleration of car while parking vehicle on December 20, 2023 at approximately 2:00pm. The sudden rapid acceleration caused the vehicle to jump a curb and hit the base of the light pole damaging the right front of the car. Car was towed to the dealership and is currently there. If the car had not hit the base of the light pole, the car could have continued on into a driving lane possibly striking another car or pedestrian. To date , 12/31/23, the car has not been inspected to my knowledge. There was no warning lamps or messages. While reaching down to push the park button, the engine, which is normally quiet, made a loud whirring noise and then lurched forward.
