On certain vehicles, the steel wheel(s) may not have been manufactured properly. As a result, the wheel(s) could crack and separate, causing a loss of control.
Safety Risk
A loss of control could create the risk of a crash. A wheel that separates could create a road hazard for others.
Corrective Actions
General Motors will notify owners by mail and advise you to take your truck to a dealership to inspect and replace the affected steel wheel(s), as necessary.
