Rear Half-Shaft Assembly Missing Ball Bearings
The rear half-shaft assemblies may be missing one or more ball bearings from the factory. This manufacturing defect can cause vibration, clicking noises during acceleration or turning, and eventually lead to a complete loss of drive power if the half-shaft fails while driving.
NHTSA Recall N212351320. Dealers replace the left or right rear half-shaft assemblies as necessary, free of charge.
Est. Cost: $0 (recall repair)Dual-Clutch Transmission Cracked Housing
The 8-speed dual-clutch transmission (DCT) housing can develop cracks caused by porous metal castings. Owners report transmission fluid puddles under the car and eventual transmission failure. The cracked housing has been reported on Corvettes with very low mileage, sometimes under 5,000 miles. The DCT is a critical and expensive component of the C8.
Transmission housing replacement or complete transmission replacement under GM's powertrain warranty. Document any fluid leaks immediately and have the dealer inspect the transmission housing for cracks.
Est. Cost: $0 (warranty) - $8,000+ (out of warranty)Front Trunk (Frunk) Opening While Driving
NHTSA has received multiple complaints of the front trunk lid popping open while the vehicle is in motion, completely blocking the driver's forward visibility. This can be caused by the latch not fully engaging, accidental actuation of the key fob frunk button in the owner's pocket, or a defective latch mechanism.
GM recall N202311160 addressed frunk latch issues on earlier models. The BCM was updated to limit vehicle speed to 26 mph when the frunk is not latched, and the key fob frunk button was redesigned to reduce accidental actuation. Dealers also revised the interior release mechanism. Verify your vehicle has received all frunk-related updates.
Est. Cost: $0 (recall repair)12V Battery State of Charge Underestimation
The vehicle may display a low battery charge status warning despite the 12V battery being fully charged. This false warning can cause concern for owners and may lead to unnecessary battery replacements. The issue stems from the BCM software incorrectly estimating the battery state of charge.
GM service update to reprogram the BCM software to correctly calculate the 12V battery state of charge. Dealers perform the software flash free of charge under the service update program.
Est. Cost: $0 (service update)Infotainment and Electrical Glitches
Owners report various electrical issues including the infotainment screen freezing or going blank, the rearview camera intermittently failing, wireless Apple CarPlay disconnections, and the HVAC system displaying incorrect temperatures. Some owners also experience intermittent power window failures and erratic behavior from the electronic door release.
Infotainment and BCM software updates. Replacement of the infotainment module in severe cases. Check all electrical connectors behind the dashboard for proper seating. Battery and charging system test to ensure proper voltage.
Est. Cost: $0 (software update) - $1,500 (module replacement)2 NHTSA safety recalls for the 2021 Chevrolet Corvette. Check your VIN at NHTSA.gov
