Verdict
The first mid-engined Corvette, sold in Europe from the second half of 2021, in Stingray, Z06 (5.5 L naturally aspirated V8) and E-Ray hybrid versions. The best-documented fault concerns the Tremec dual-clutch gearbox (GM investigation in 2021, 2024 bulletin on loose mountings), and a batch of defective valve springs affected engines built in 2020: check the recalls and the history of each car.

Tremec TR-9080 dual-clutch gearbox: leaks and faults
Severity 2/3 · CostlyAt the end of 2021 GM opened an investigation into the 8-speed dual-clutch gearbox of 2020-2022 Corvettes: leaks (seals), error messages asking the driver to shift to P, and a discharged battery in some cases. GM issued several technical bulletins, including a software update. Most reports come from owner forums, so the real frequency is uncertain.

Inspection checklist
Chevrolet Corvette C8 — inspection checklist
Things to check
- Ask for the serial number and have a Chevrolet dealer check the recalls, bulletins and updates (gearbox, valve springs).
- 2023-2024 car: check whether the gearbox has been replaced under the mounting bulletin (invoice and repair order).
- Full test drive: gear changes when cold and warm, jerking, error messages on the dashboard.
- Check the service history of the dual-clutch gearbox (filters and fluid according to GM bulletins).
- 2020 engine: listen for knocking or irregular running and ask whether the valve springs have been checked.
Questions to ask the seller
- Has the gearbox been repaired or replaced? Do you have the repair orders?
- Have all GM recalls and bulletins been carried out by a dealer?
- Where and how was the car imported, and with what specification (European or American)?
Test-drive tip: read the fault codes
A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.
