The official notice
Defect
On certain vehicles, recall 2021-103 may not have been properly completed. As a result, a second inspection is necessary. Certain vehicles were built with tires that may have been cured too long. As a result, the sidewall could crack or the tread and belts could separate. This could lead to a sudden loss of air pressure and could cause a tire failure. Note: This recall only affects certain Continental tires, with specific date codes and mold numbers. Vehicles subject to this recall were previously inspected under GM recall N212329050 (TC 2021-103) and require subsequent inspection.
Safety Risk
A tire failure could cause a loss of control and increase the risk of a crash.
Remedy
General Motors will notify the owners by mail and instruct them to take the vehicle to a dealer to inspect and replace the tires, if necessary.
