NHTSA recall 21V578000
Tires · General Motors, LLC
Details
What's wrong: General motors, LLC. (gm) is recalling certain 2020-2021 Chevrolet Silverado 2500 and GMC Sierra 2500 vehicles equipped with a 17" spare tire (rpo zhq or zxt) and either the 20" accessory road tire (rpo rem) or the 18" accessory road tire (rpo q2v). Operating the spare tire with other 20" or 18" tires can prevent the anti-lock braking system (ABS) from engaging.
Why it matters: An ABS system that cannot control the rear wheels independently increases the risk of a crash.
The fix: Dealers will provide the appropriate spare tire and apply a new spare tire information label, free of charge. Owner notification letters were mailed on October 18, 2021.
