What this recall means for you

Some tires on certain 2019 Chevrolet and GMC full-size pickups were cured (vulcanized) for too long during production. Over-cured tires can develop a break in the sidewall, causing sudden air loss, or a separation between the belt and the tread, which can lead to tread or belt loss.

Either condition can cause a loss of vehicle control and increase the risk of a crash. Owner notification letters were mailed on June 25, 2021.

Authorized dealers will inspect the tires and replace them as necessary, free of charge. Owners can contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. Check your vehicle's VIN for open recalls to confirm whether your truck is affected.
