2020 GMC SIERRATransport Canada Recall #2020530
The official notice
Defect
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 vehicles equipped with certain Continental tires, with specific date codes and mold numbers.
Safety Risk
A tire failure could cause a loss of control and increase the risk of a crash.
Remedy
General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the tires and replace the ones that have the DOT number and production mold number combinations identified by Continental.
