## What is 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.


## What can happen

An ABS system that cannot control the rear wheels independently increases the risk of a crash.


## The remedy

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.  Owners may contact Chevrolet customer service at 1\-800\-222\-1020; GMC customer service at 1\-800\-462\-8782.  GM's number for this recall is N212329780.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.nhtsa.gov.
