General Motors is recalling 86 model year 2020-2021 Chevrolet Silverado 2500s and GMC Sierra 2500s 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.
An ABS system that cannot control the rear wheels independently increases the risk of a crash.
What to do
Dealers will provide the appropriate spare tire and apply a new spare tire information label free of charge.
Owner notification letters are expected to be mailed September 13, 2021.
Owners may contact Chevrolet customer service at (800) 222-1020 and GMC customer service at (800) 462-8782. GM's number for this recall is N212329780.
