The tires may have been manufactured with an insufficient amount of curative agent, which could cause tread separation.
Tread separation can result in tire failure and a loss of vehicle control, increasing the risk of a crash.
What to do
Dealers and authorized independent service centers will replace the affected tires free of charge.
Owner notification letters are expected to be mailed July 29, 2021.
