General Mortors has decided that a defect affecting vehicle safety exists in some tires installed as original equipment on certain 2018-2021 Buick, Cadillac, Chevrolet and GMC trucks and SUVs.

According to the tire manufacturer, Continental Tires the Americas (CTA), the tires may have been over-cured and could experience an unexpected break in the sidewall. This break could lead to sudden loss of pressure or a belt edge separation that could lead to partial or full tread / belt loss. The problem could increase the risk of loss of vehicle control.

GM will notify owners and dealers will inspect and replace tires as necessary. The recall is expected to begin April 12, 2021. GM’s number for this recall is N212329050 and the NHTSA campaign number is 21V-115. Approximately 34,000 vehicles are affected.
