2027 Chevrolet Bolt Ev

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 another unexpected propulsion event. The vehicle has also experienced charging/range abnormalities, and code P3013 was among the codes retrieved by the dealer. I do not know whether those issues are related to the lurch event, and I am not asserting that they are. I am reporting them because they may be relevant to NHTSA’s evaluation of the vehicle’s electrical and control systems. I am requesting that this incident be recorded as a potential safety defect
