2027 Chevrolet Bolt EV

Defect. General Motors has decided that certain 2027 Chevrolet Bolt EV, 2025-2026 Cadillac OPTIQ, Chevrolet Colorado, Equinox EV, GMC Canyon, 2026 Buick Enclave, Envision, Cadillac CT5, Escalade, Escalade ESV, Escalade IQ, Escalade IQL, LYRIQ, VISTIQ, Chevrolet Blazer EV, Corvette Convertible, Corvette Coupe, Corvette Convertible E-Ray, Equinox, Silverado 1500, 2500, 3500, Silverado EV, Suburban 1500, Tahoe, Traverse, GMC Acadia, Hummer EV Pickup, Hummer EV SUV, Sierra 1500, 2500, 3500, Sierra EV, Terrain, Yukon, and Yukon XL vehicles. The radio may not have been set to the correct status to download the electronic owner's manual during production. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, “Occupant Protection.”

Risk. Without an owner's manual to consult, owners may not know how to safely use and operate the vehicle, increasing the risk of injury in a crash.

Remedy. Dealers will reset the vehicle radio, which will facilitate automatic download of the electronic owner’s manual, free of charge. Owner notification letters were mailed April 16, 2026. Owners may contact GM customer service at 1-866-467-9700, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-333-4223. The manufacturer's number for this recall is N252540430. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on February 26, 2026.

I am reporting a serious vehicle control hazard concerning the One-Pedal Driving (OPD) implementation on the 2027 Chevrolet Bolt RS. The vehicle enforces automatic rolling/creeping behaviors in reverse, creating a dangerous conflict with muscle memory. When One-Pedal Driving is active, a driver expects the vehicle to come to a complete stop and hold when lifting off the accelerator. However, because the system does not allow the customization or complete disablement of OPD or the creep function while in reverse gear, it introduces a severe human-factors safety risk during low-speed maneuvers. A driver relying on muscle memory expects the car to brake when the pedal is lifted, but the unexpected low-speed creep requires an urgent, secondary foot transition to the physical brake pedal. This lack of software configuration increases the risk of low-speed collisions and pedal misapplication during backing maneuvers. Requesting a software update from the manufacturer to make One-Pedal Driving behaviors or vehicle creep fully optional and independently toggleable when operating the vehicle in reverse gear.

This is in regard to the automatic emergency braking function in my new 2027 Chevrolet Bolt. While driving, the emergency braking system suddenly activated the brakes. It was unanticipated, unnecessary, and violent to the extent my wife, in the passenger seat, later reported headache and neck pain. I did not report this to the dealer and it has not been inspected. Apparently, this is what the car is designed to do. I have managed to turn off this system but it defaults to "on" every time I turn the car off. There appears no permanent way to deactivate this system.

The brake pedal can easily become disconnected from the electronic brake booster behind the firewall. When this happens, it stops all driver aids. The safety issue is it can happen while driving, and if using adaptive cruise control, or GM super cruise, if one pedal driving is on, it can without warning substantially slow the car, and has the potential to cause an accident. Its not too far to think the dislodging can cause the boost arm to be placed in a position to prevent full brakeing either. I have not taken it in because it is a design flaw of the system I believe. From searching online, I found the assembly, and it lacks a locking pin in the pedal to the shaft as you can see in the service diagram attached. Speaking to someone at a GM dealer they verified the issue on another 2027 Chevy Bolt, but not reproducible on other GM vehicles with the same electronic brake boosting system.

2027 CHEVROLET BOLT – SUDDEN FORWARD LURCH / PROPULSION EVENT WITH MULTIPLE COMMUNICATION FAULT CODES While driving my new 2027 Chevrolet Bolt, I was stopped at a traffic light. When the light changed, I applied the accelerator gently to move forward. The vehicle suddenly produced a loud bang or clunk and lurched sharply forward. All of the yellow instrument panel lights flashed on for a few seconds. The acceleration was abrupt and substantially different from my accelerator input. Surrounding drivers were alarmed. The event was sufficiently forceful and unexpected that I considered it a safety issue involving propulsion control. I was not accelerating aggressively; this was a gentle acceleration, in traffic, making a left turn onto a freeway ramp. I subsequently brought the vehicle to the Chevrolet dealer for diagnosis. The dealer retrieved the following diagnostic trouble codes: U164B; U164E (5 times); U0485; U11FD; P3013; U1A25; U160A (3 times)l U197A (3 times); U0159; U1126 (2 times); U1150; B1A25; U1607; U1151 Several of the retrieved codes are U-series communication/data-network codes. The vehicle has now been at the dealership for three days; so far the dealer has not provided an explanation for the sudden lurch or identified the underlying cause of the diagnostic codes. Previously the car was at the dealership for 15 days. I am concerned that an intermittent electronic, communication-network, propulsion-control, power-supply, software, or related fault could cause ano

The contact owns a 2027 Chevrolet Bolt EV. The contact stated that while driving approximately 65 MPH with the Adaptive Cruise Control activated, the braking system suddenly activated causing the vehicle to abruptly decelerate when another vehicle passed by. The contact stated that the failure had occurred on two separate occasions while being overtaken by another vehicle on the passenger’s and driver’s sides. The vehicle was taken to the local dealer to be inspected; however, no cause for the failure was found. The manufacturer was notified of the failure. The failure mileage was 900.

The main infotainment screen provides the critical safety rear view display screen for the rear view camera. This is a legally required function for this vehicle, a 2027 Chevrolet Bolt RS. The failure of the screen means that a clear view towards the back of the vehicle is unavailable. Reversing without the display is hazardous and may result in hitting an object, animal, or person. Online Chevrolet customer service suggested a soft reset. This did not solve the problem. The problem has been intermittent, but is now permanent. The vehicle, which has only 500 miles and is under its new car warranty, was brought back to a Chevrolet dealer. The dealer disassembled the screen and confirmed the screen failure. The dealer does not have the part. The manufacturer doesn't have the part. The dealer is ordering it from a 3rd party. There is no estimated time for receiving the part.
