July 29, 2021 NHTSA CAMPAIGN NUMBER: 21V578000

Spare Tire is Incorrect Size

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

 

NHTSA Campaign Number: 21V578

Manufacturer General Motors, LLC

Components TIRES

Potential Number of Units Affected 86

 

Summary

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.

 

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.

 

Check if your Vehicle has a Recall

 


Condition

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2020 – 2021 model year Chevrolet Silverado 2500 and GMC Sierra 2500 vehicles equipped with a 17” spare tire (RPO ZHQ or ZXT) and either (i) the 20” accessory road tire (RPO REM) or (ii) the 18” accessory road tire (RPO Q2V). The GM recall number is N212329780. If the 17” spare tire is installed at one of the rear locations in these vehicles while one of the listed accessory tires is installed in the other rear location, differences in revolutions per kilometer (RPK) between the rear tires may prevent the anti-lock braking system (ABS) from controlling the rear wheels independently on low friction surfaces. If the ABS system cannot control the rear wheels independently on low friction surfaces, there is an increased risk of a crash.

 

Correction

Dealers will provide an 18” spare tire and wheel assembly to owners who purchased the 20” or 18” accessory road tires. Dealers will also apply a new spare tire information label over the existing tire placard label. Owners will also be provided an Owner’s Manual insert explaining the 18” spare tire that should be used with 18” or 20” accessory road tires and the 17” spare tire should be used with the 17” original tires.
