General Motors is recalling 3,241 model year 2021-2022 Chevrolet Silverado 2500s, Silverado 3500s, GMC Sierra 2500s, and Sierra 3500s with electronic brake control modules (EBCM) replaced during vehicle assembly.
The bolts that attach the brake pressure modulator valve (BPMV) assembly in affected vehicles may not be tightened properly, which could fail to seal the two sub-assemblies and allow water intrusion.
Water in the BPMV may cause an electrical short circuit and increase the risk of fire.
What to do
Owners are advised to park outside and away from other structures until the recall repair is completed. Dealers will replace the BPMV assembly free of charge.
Owner notification letters are expected to be mailed on November 15, 2021.
Owners may contact Chevrolet customer service at (800) 222-1020 or GMC customer service at (800)462-8782. GM's number for this recall is N212349181.
