Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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 miles“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 2026-06“We have a water leak that was coming in both windows and onto the floor. Since reported it the car will slow down while driving because of codes issues about the doors are not closed and it is. I feel it's due to the water leak that is coming into the car. Took the car to a Chevrolet Dealer in Columbia South Carolina and they said it was coming from the roof weather stripping. They said it wasn't a recall for the 2020 C8 Corvette corvette yet. Also called GM Customer care to see if I can get some help to get it fixed. No luck.”
