Known problems
- Classic four-piston brake caliper leakscritical
From 1965 the Corvette used four-wheel disc brakes with four-piston calipers. Over time, moisture in the brake fluid pits the caliper bores and the seals start leaking. A common fix is rebuilding the calipers with stainless steel sleeves, which resist pitting.
- 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.
- 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.
- C7 8L90 automatic shuddermoderate
Many 2015–2019 C7 owners with the 8-speed 8L90 automatic report a shudder or vibration at light throttle, often felt like driving over rumble strips. GM issued service information related to the transmission fluid. Ask a dealer to check your VIN.
- Wheel bearing / hub failurehigh
C5, C6 and C7 Corvettes use sealed hub bearing assemblies. They wear over time, especially with wide tires, track use or impacts. A failing hub causes a hum or growl that changes with speed and cornering.
