2023 Chevrolet Bolt EV Electrical System Problems

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.

THIS VEHICLE JUST STOPPED IN THE MIDDLE OF TRAFFIC, NOT GIVING ME TIME TO PULL OVER. THE SCREEN JUST SAID, "SERVICE MODE", AND WOULD NOT GO INTO NEUTRAL TO ENABLE THE CAR TO BE PUSHED TO A SAFE SPOT. HIGHWAY PETROL HAD TO STOP TRAFFIC AND HAVE IT TOWED OFF. THIS WAS ENDANGERING EVERYONE INVOLVED. IF THIS IS A COMMON PROBLEM WITH OTHER CHEVY BOLTS, IT DEFINITELY NEEDS ADDRESSING.

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.

I was sitting in the passenger seat of my new 2023 Chevy Bolt EV while parked at a convenience station. The vehicle was on and not hooked up to a charger. I smelled something burning and quickly thereafter I saw smoke coming from under the driver side seat. The driver exited the vehicle and looked under the seat. The driver attempted to put out the fire with his hand and the carpeting under the seat. The fire got bigger. I ran to the closest extinguisher and pulled the pin to extinguish the fire. It was out for several seconds before re-igniting again. Another round of extinguisher foam was released and the fire was put out. I reported the damage to the dealership, the car manufacturer and my insurance company. I towed it to the dealership where it has been sitting since 6/1/24. Nothing further has been done since then. The dealership refuses to assess the vehicle and to date the manufacturer has not sent any inspectors to diagnose the reason of the fire. As A matter of fact my insurance company, the dealership and the manufacturer all advised me to get and pay for my own inspection from a 3rd party inspector which I am working on scheduling now.

See attached document for complaint

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.

On 11-17-23 someone rear ended me making me lose control of the vehicle and getting off the road into the woods and eventually hitting a tree, the airbags did not deploy, the car is equipped with OnStar system from Chevrolet as a safety feature in which as soon as there is a collision I supposed to get a call from an advisor so they could call an ambulance and a towing service, it's included in my monthly payment, but that did not happen, no one called me to check on me also the braking system should have prevented me from hitting a tree, the safety system failed

The contact owns a 2023 Chevrolet Bolt EV.

The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced the failure. VIN tool confirms parts not available.

Was sitting at a stop light when I accelerated on green I felt a lurch, it felt like someone had hit me from behind. Within 15 seconds of acceleration this light came on, a car with an exclamination point on it, and said to pull over ASAP. Car would not go any faster than 30mph and luckily I was not on an interstate or major highway. I was able to pull over in a parking lot and at that time the car was disabled. I could not put it in driver or reverse and it did not want to turn off I had to open the door to turn it off. On Star diagnostics said it was the electric drive unit not preforming as expected, codes P0A3F and P0A40. Car would not move and luckily it was daylight in the area I was at, at night this would have been bad as I would have feared for my safety as a female alone in a car that would not go. Car had to be towed to dealership and from the dealer "drive motor position sensor erratic. Found bulletin 19-NA-220 to replace engine harness (42840881 2525C F-HARNESS) for this concern due to improper instatallation of harness causing issues due to terminal damage".

My wife had just parked the vehicle in our garage and had plugged it into the charger. She walked to the back of the vehicle to open the rear hatch and as she was raising the hatch she felt an electrical shock up her arm, it was strong enough that she immediately came into the house holding her elbow. It couldn't have been static electricity, she was already in contact with the vehicle when the shock occurred, the humidity was very high as it had been raining, plus the vehicle should be grounded through the charging plug. I immediately went into the garage and unplugged the car. Tomorrow I'll plug the car back in and use my voltmeter to check for any voltage between the vehicle body and ground.

I have purchased the Autel Energy EVSE for my vehicle and had it installed by certified electricians in my garage. The unit malfunctions frequently and requires it to be restarted. The unit is hard wired and and the only way to reset it is to turn the breaker off and back on, as instructed by the manufacturer. NEV specifically says that using the breaker as a switch is no recommended. The purpose of the breaker is a power interruption device in case of an electrical fault. Using it as a switch to turn power off and back on could prematurely wear it out which creates a fire risk. The manufacturer has explicitly instructed me to create a fire hazard in my home to be able to use their product. This is a serious safety hazard.
