Known problems
- C8 DCT low-speed clunk or shuddermoderate
Some C8 owners report clunks, shudder or harsh engagement from the TR-9080 dual-clutch transmission at low speeds, such as parking, creeping in traffic, or shifting into drive or reverse. Some of this is normal DCT behavior, but some cases need a dealer to check.
- C7 Z06 heat soak on trackmoderate
Some C7 Z06 owners, especially with early cars on hot days, report the car reducing power or showing high temperature warnings after a few hard laps. The supercharged LT4 creates a lot of heat. GM made changes to later cars, and the aftermarket offers cooling upgrades.
- C7 cast wheel cracking or bendinghigh
Many C7 owners, especially with wide-body Z06 and Grand Sport cars, report cracked or bent factory cast wheels, often after potholes. Cracks are usually on the inside barrel, out of sight. Low-profile tires and big wheels leave little cushion.
- Classic Corvette overheatinghigh
C1 through C3 Corvettes have tight engine bays and old cooling designs. Many run hot in traffic or on warm days, especially after decades of mineral build-up, missing seals, or mismatched parts. Most cases come down to airflow, the radiator, the fan or the ignition timing.
- C6 clutch pedal sticks to the floorhigh
Some C6 manual owners report the clutch pedal staying on or near the floor after high-RPM shifts, usually during spirited driving or on track. It's commonly linked to the clutch hydraulic system, with heat and aged fluid often blamed.
