What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The brakes have now four times failed to stop the vehicle. When pressed they get hard, then go down to the floor and there's a pulsating feeling. The vehicle just continues to go to the floor.
Vehicle had a shake, and felt like it was shifting wrong. Apparently, Two of the four rims have were confirmed cracked which led to an unsafe vehicle for travel. The vehicle had approximately 15,230 miles on the tires and rims when air was leaking out. All four tires were shot.
Prior to warranty expiration I took my car to be checked for vibration at highway speed. McMulkin Chevrolet NH told me they had to change the fluid in the transmission. This did nothing for the problem. During this time the drivers side tires would lose tire pressure faster than what is acceptable.
When the tire loses air the low tire warning light comes on and more air must be installed but as i was stranded on Easter Saturday and Sunday waiting too order a new wheel making it impossible to travel as i could only get about 25 miles after putting additional air in the tire.
While driving 45 mph, there was a violent vibration in all four tires without warning. The contact noticed that the thread was separating from each tire. The vehicle was taken to roger dean chevrolet ([address], cape coral, [ZIP], [phone]) two days prior to the failure, but no failure was found at that time.
During the second session on day two my 2018 z06 had a power steering issue. Without any warning, I felt and heard a loud thump through the steering wheel as I approached turn 3 from no-name, I had very little steering ability that required heavy handed input on the steering wheel causing me to lift and brake to keep…
8-speed automatic transmission 'bucks' and 'clunks' during acceleration or during up shifting. It does this either in full automatic or manual shifting mode.
Two brake rotors on 2018 corvette grand sport have permanent rust bands that do not wear off under braking. They are scoring and grooving the brake pads instead. Gm blames the dealer for poor maintenance but neither will replace because they say it's only 'cosmetic' according to them.
