Example complaints
Body and structure: “I was pulling out of the driveway and onto the city road driving about 30-40 MPH and my front trunk opened on it's own. I had no warning signs or got no audible alerts when my front trunk opened on its own. I've been in contact with my dealership and they said GM warranty will not cover the problem or fix my damages, that my insurance needs to cover that.”
NHTSA complaint #11338933, filed 2020-07, 5 milesTransmission and drivetrain: “My left rear axel/rear differential/ control arm snapped with normal driving and breaking. It is available for inspection. This mechanical failure made me loose control of my vehicle on the busy freeway and threw me across a lane into the freeway center divider. Nearly caused a pile up accident and killed me.. The dealership service department checked it in today. I filed a claim today with the manufacture but nobody looked at it yet. There were no warning lamps and i believe there is still no warning lamps”
NHTSA complaint #11742799, filed 2026-06Other or unknown: “The front trunk lid (the lid) opened at a speed of about 40mph on a city street. The warning light was not lite prior to this incident and nothing activated the lid door switch. This incident bent the lid hinges and dis-aligned the lid resulting in the damaging of the corners of the quarter panels. I have now taped down the lid in front to prevent this occurring again. I have notified my chevy dealer of this incident and will be replacing the hinges and repair the quarter panels.”
NHTSA complaint #11339918, filed 2020-07, 1,500 milesEngine: “Car is equipped with remote start. On april 20th I parked in the garage, put groceries away including some that went in the fridge in the garage. The Corvette keys were in my pocket. I set a timer for one hour for items I had put in the garage freezer to chill. When I went back at the one hour alarm, the vehicle was running in the closed garage. To use remote start the vehicle has to be locked first and I never lock the vehicle in a closed garage. Chance motion of those keys in my pocket had locked the vehicle and initiated remote engine start. …”
