2022 Chevrolet Corvette 6.2L Petrol · NK22 EUZ

Early Corvette C8 models equipped with the Tremec TR-9080 8-speed dual-clutch transmission can experience fluid weeping from the transmission oil pan gasket, as well as electronic sensor and solenoid valve body anomalies. Stamped steel pan flex and internal debris can cause transmission warning alerts ('Service Transmission - Put in Park'), rough shifting, or failure to engage reverse, requiring dealer flushes, revised aluminium pans, or valve body replacement.

On C8 Corvettes optioned with the front suspension lift system (which uses pressurized DOT 4 brake fluid to raise the nose by 40mm over speed humps), the original factory reservoir cap featured an atmospheric vent. Under hard driving or when actuating the lift on inclines, fluid slosh causes corrosive brake fluid to escape through the vent cap, pooling on the reservoir and potentially corroding surrounding bodywork and wiring. GM issued TSB N202321570 specifying an updated non-vented cap.

Early C8 Corvettes can suffer from failing fuel level sensors and fuel pumps. Erroneous low-fuel warnings, fluctuating gauge readings and check engine lights can appear even when the tank is full, leaving the driver unsure of actual range and at risk of running out of fuel unexpectedly. In some cases the fuel sender unit or pump requires dealer replacement, which involves draining and dropping the tank on the mid-engine layout. This is a known issue on early UK right-hand-drive examples and can be expensive given the limited Corvette dealer network.
