Chevrolet Corvette C8 Could Have Wheel Problems Too

Sports Cars / 28 Comments

Over 13,000 Corvettes could experience this porosity issue.

Early adopters of the 2020 Chevrolet Corvette Stingray were unhappy when they discovered quality control issues with the interior leather stitching, but now the mid-engine sports car has a more serious problem. Last year, owners of the last-generation Chevrolet Corvette Z06 and Corvette Grand Sport sued General Motors after discovering cracks on the wheels due to materials that were cast rather than forged, and now the wheels on the C8 Corvette may have a fault. But this one has to do with pores developing in the wheels.

According to a service update bulletin (different than a technical service bulletin) by General Motors published by Corvette Blogger, the Corvette Stingray "may have a condition where exposed porosity in wheel castings are larger than allowed and do not meet internal GM requirements."

In other words, cracks are forming on the wheels again, which could cause a tire puncture and lead to an accident. 2020 and 2021 model year Corvettes fitted with Open Spoke and Trident Wheel designs are affected. In the US, 13,049 C8 Corvettes will need to be inspected. Out of these models, GM believes 10 percent are affected by the wheel defect. Owners are advised to visit their local Chevrolet dealership for a service to have all four wheels inspected by technicians and replaced if necessary.

GM says that "the issue is a cosmetic one, which could cause a slow leak in the tire. If the leak developed, customers would receive a message on their cluster that the tire pressure is below recommended limits. When a customer brings their vehicle in for service, dealers will inspect the wheels to see if this issue is present and replace the wheels."

If a wheel has any deep blemishes, technicians will drill a 0.5-inch hole through the rim barrel of the wheel so they can't be used again. Faulty wheels will then be disposed of through a metal recycler.

You have to commend General Motors for taking responsibility this time and replacing the wheels free of charge, but this won't improve the C8 Corvette's reputation when it comes to quality control. Last year, videos emerged online showing the frunk on some C8 Corvettes flying open, blocking the driver's visibility. In a separate issue, the frunk lid release button was prone to failing after the car was shut down.

Teething issues are common for brand new models, but let's hope General Motors has learned from these issues and can improve the quality control for future C8 Corvette iterations. Orders for the 2021 Corvette Stingray have been stopped due to high demand, but the order books for the 2022 model will open in early July.
