Known issue with " anti click washer on Bolt Ev " and resulting damage to related components can cause loss of control acceleration, stopping and major damage and cost, no warning lights or TSB other than for previous gen but same design and same defect, inspected by dealer shows broken anti click washer and damage to other components https://gmauthority.

While driving at approximately 45 mph, the regenerative braking feature of the vehicle suddenly failed, and also generated a master caution light on the dashboard display. This is the second time this has happened while driving and resulted in a sudden, alarming change in vehicle dynamics. Regenerative braking is the normal operation regime of the vehicle, with the traditional mechanical-hydraulic brake pedal available for added braking, as demonstrated by the Chevrolet dealership during a test drive and confirmed with the vehicle manual. Furthermore, the vehicle will no longer shut itself off and could pose a fire risk when stored in a garage, parking deck, other vehicles, etc. These issues happened in November 2024. The car was returned to the dealer for warranty repair. Even after extensive repairs to the electrical system, the car has repeated the alarming failure mid-drive. This indicates that there is a serious problem with the electronic and poses a serious safety risk.
The brake/turn signal lights on all of the bolts, including mine, are barely visible during the day. It needs to be recalled. The lights are tiny.
I was approaching an intersection at a light that had turned red. I slowed down to stop but accidentally bumped into the car in front, 2 mph (approximately), no damage, not even a scratch. I put the vehicle in reverse and gently tapped the accelerator but it instantly raced backwards at full as though the accelerator pedal had been depressed to the floor. I tried to brake but it would not stop and smashed into the vehicle behind. It was scary and traumatizing. Sudden acceleration in reverse. I hope there are diagnostics that will corroborate what happened because I am certain to the highest degree that this vehicle is defective.
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.
The contact owns a 2023 Chevrolet Bolt Ev. The contact stated that while driving approximately 30 mph the driver pressed the brake pedal but the vehicle did not stop and crashed into the rear of a second vehicle. The contact indicated that during the crash the vehicle was low on electrical charge and was being operated in the "one pedal" mode and the the air bags did not deploy. The rear passenger seated on the passenger side sustained an injured neck which did not require medical treatment. A police report was taken at the scene and the vehicle was driven away. The cause of the failure was not determined. The rental company was notified of the failure. The manufacturer was not contacted. The failure mileage was unknown.
2023 chevy bolt has a hand 'regenerative brake'. I was using it while driving in traffic. My speed was around 40 mph when the car in front of me abruptly stopped. The distance between us was approximately 30 ft. I immediately switched from hand brake to foot brake and the pedal felt soft and there was a delay in response to foot brake. I rear ended the vehicle in front of me causing damages to both vehicles. This had happened in August 2023. I called the manufacture to let them know what happened and they told that they will pass the information. I made a call to them in December of 2023. My vehicle was not inspected for this issue as I am not sure who can help me with this problem. There were no warning lights before the accident. Ever since the accident I have tested switching from 'hand brake' to foot brake and always feel a softer pedal and a slight delay in response. I believe this issue was a main factor for the accident as in my over 10 years of driving experience I have never had an accident before. I believe that the 'hand brake' is using electric motor while foot brake uses regular hydraulic system and they are not adjusted properly when are switched in between.
Yes I almost got rear-ended three times in the last 3 weeks because the brake lights on the chevy bolt are below the bumper and the tail lights do not go on when you step on the brakes only the collision lights and the turn signal lights.
