Certain vehicles were built with tires that may have a manufacturing defect. As a result, the tire tread could separate while driving.
Note: This recall only affects certain Hankook tires with a date code of 0521, and a specific internal bar code.
A tire tread separation could affect vehicle handling and increase the risk of a crash.
General Motors will notify owners by mail and instruct you to take your vehicle to a dealer to inspect and replace the tires, as necessary.
