2027 Chevrolet Bolt problems

“1. Unexpected sudden automatic hard braking during normal conditions-many times so far. -Dealer blamed it on the poor quality of the sensor and automatic braking system on the 2027 chevy bolt. 2. Wandering steering and failure for steering wheel to return to center after minor turns and lane changes. wandering steering/tracking fixed after dealer replaced the rack/steering gear but the "return to center" failure still persists. I am taking it in for the 3rd time tomorrow (11/45/2026)”

“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.”

“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.”

“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…”

“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.”
