5 known faults

Stingray 6.2 V8 466 ch 7 rapports manuelle

  1. Faulty AFM lifters on the LT1 V8

    Severity 2/3 · Costly

    On the LT1 V8, owners report knocking from the top of the engine, misfires (codes such as P0300 or P0307) and cylinder deactivation (AFM) lifters that are stuck or collapsed. A faulty lifter can damage the camshaft; the GM bulletin provides, as a last resort, for engine replacement. A buying guide estimates the repair at between $1,500 and $3,000.

  2. Fuel filler pipe (2014 recall)

    Manufacturer recall

    A recall concerns 2014 Stingrays whose anti-siphon screen in the fuel filler pipe could be incorrectly positioned; the remedy is replacement of the pipe by the dealer network (Corvette Blogger). CorvSport also reports petrol smells among the most frequent complaints on the C7, and a GM campaign on this pipe. Check the VIN.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

  2. Cracked or warped alloy wheels (Z06 and Grand Sport)

    Severity 2/3 · Costly

    Class actions have been brought against GM over cracked or warped cast wheels on 2015-2019 Z06s and 2017-2019 Grand Sports, with owners stating that their warranty claims were refused. The proceedings led to a reimbursement programme subject to conditions (The Drive). Check the condition of each wheel.

  3. 8-speed automatic gearbox: jerking at low speed

    Severity 1/3 · Annoying

    C7 owners describe jerking or hesitation at low speed with the 8-speed automatic gearbox (Haynes); CorvSport also mentions a class action targeting this gearbox. GM service bulletins and fluid changes exist, without any guarantee of a solution.

Z06 6.2 V8 compressé 659 ch 7 rapports manuelle

  1. Overheating and reduced-power mode in track use (Z06)

    Severity 2/3 · Costly

    GM describes overheating that can trigger a reduced-power mode during sustained high-speed driving in hot weather, on 2015-2018 Z06s. The warranty has been extended to 7 years or 72,000 miles (about 116,000 km) from first entry into service, regardless of owner; the correction involves an updated radiator and, on automatics, an updated gear-shift software. Several class actions have been filed.
