Tire/wheel issue
TIRES:TEMPORARY/EMERGENCY SPARE TIRE
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.
Consequence
An ABS system that cannot control the rear wheels independently increases the risk of a crash.
