General Motors has issued a service update to address an issue related to the construction of the alloy wheels on certain examples of the 2020 and 2021 model-year C8 Corvette Stingray.
The problem: certain C8 Chevrolet Corvette vehicles may have a condition where exposed porosity in wheel castings are larger than allowed and do not meet internal GM requirements. In simpler terms, some Corvette wheels may have visible holes in the surface due to a fault in the casting process. Only around 10 percent of the wheels on affected vehicles are believed to have this problem.
The hazards: while this issue does not pose an immediate safety risk to vehicle occupants, owners may not appreciate the way the large pores on the surface of the wheel look. The service bulletin did not indicate if this issue affects the structural rigidity of the wheels.
The fix: dealers are instructed to inspect and replace wheels that do not meet internal GM requirements.
Affected components: alloy wheels.
