While the reception of the 2020 Chevrolet Corvette Stingray has been extremely positive, some owners have discovered an embarrassing quality issue. A few weeks ago, photos posted online showed how the stitching on the leather dashboard doesn't run smoothly. However, this is a relatively minor defect compared to a more serious issue C7-generation Corvette owners are complaining about. For years, owners have been reporting that their wheels have been cracking on the C7 Corvette Z06 and Corvette Grand Sport.

Now, a class-action lawsuit has been filed against General Motors on behalf of owners of 2015-2019 Corvette Z06s and 2017-19 Grand Sports. Filed in the United States District Court, Northern District of California, by Kehoe Law Firm, P.C., the lawsuit claims the wheels "are prone to bending and cracking, necessitating costly repairs and replacements."

This is obviously a huge safety hazard because the cracks "can puncture the tires, causing air leaks and tire blowouts."

According to the lawsuit, the rims are being made with a cheaper cast material instead of forged, which is causing the cracks. GM also allegedly used less material than necessary to save unsprung weight. As a result, the the rims are too weak under normal conditions. To make matters worse, the lawsuit claims that Chevrolet has been denying claims made by owners about the wheel cracks and refusing to cover repair costs, despite the cars being covered by a three-year, 36,000-mile bumper-to-bumper warranty.

General Motors responded to customers saying the wheels are not defective and the cracked wheels are "caused by potholes." As a result, owners have had to spend thousands of dollars to repair or replace the wheels.

Sadly, this isn't the first time quality concerns have been raised about the C7 Corvette's cracking wheels. Owners have been reporting the issue on online forums for years, and Car & Driver had to replace or repair six damaged wheels during its 40,000-mile test period with a 2017 Chevrolet Corvette Grand Sport.
