“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”Owner report · Unknown Or Other · Jun 2026

“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.”Owner report · Visibility/Wiper · Nov 2025

“Periodically the Instrument Cluster(Speed, Tach and other gauges) goes black. When this happens you have know knowledge of any information about the vehicle speed, etc.. This lasts a variety length of times, but no longer that about 1minute. The instrument cluster then reappears, but usually will go out again in a few minutes. A message appears, "Service Instrument Cluster'" This will happens 4 or 5 times in a period of around 10 minutes then it will never happen again the rest of the current drive. This may not happen again for a couple of months of driving then it does it again.”Owner report · Unknown Or Other · Aug 2024
“I had a complete transmission failure while on a road trip over July 4th. I just read that GM was doing a recall on the Transmission Control Module but it does not include my car, which is what failed on my car at 19,000 miles. My trip was interrupted, we spent two days paying for hotel & rental car in Springfield, MO and now my car is fixed with new TCU in Springfield, but I live in DFW area. If my car had a recall I would have had it fixed before our trip and this all could have been avoided. Now I have to figure out how to get my car back home.”Owner report · Power Train · Jul 2023
“Gm refuses to replace the brake module despite the fact that this has been known since september 2020. The remedy "is incomplete"and parts are not yet available. It is ludicrous to assume that parts on a currently produced car are not available. They are installing this module daily. These are brakes that can fail and can cause an accident when they do fail.”Owner report · Service Brakes · Feb 2021
“At the time of incident the vehicle had 660 miles. Most of the accumulated miles are: 60% street and 40% hiway. I was inspecting the wheels and tire when I spotted a significant amount of grey/black colored grease randomly covering the inner wheel. Upon further inspection I noticed that the grease was splattered on the emergency brake unit, sensors and wiring harness. The grease was isolated to the rear passanger axle. I suspect that the grease came from a defective cv boot. Took vehicle in to checkout the problem and they determined the grease was from a defective cv boot. New axle was ordered.”Owner report · Power Train · Dec 2020
“This complaint is a result of gm non action to their recall a202307260. It has been 2 months since the recall has been announced and parts or not available. Loss the the affected item (brake booster) severely impacts safety that could cause an accident resulting in severe injuries or death. Gm has parts -- they are building 180 units per day. There are under 700 - 2020 corvette cars affected by this recall. Gm is putting profit and sales ahead of safety. NHTSA should require gm to immediately use production parts to remedy this issue and close this recall considering it is safety related.”Owner report · Service Brakes · Nov 2020
