Park outside
Affected vehicles should be parked away from structures until repaired, because of fire risk.
What the defect is
General Motors, LLC (GM) is recalling certain 2021-2022 Chevrolet Silverado 2500, Silverado 3500, GMC Sierra 2500, and Sierra 3500 vehicles with electronic brake control modules (EBCM) replaced during vehicle assembly. The bolts that attach the brake pressure modulator valve (BPMV) assembly may not be properly tightened, which could fail to seal the two sub-assemblies and allow water intrusion.
Why it matters
Water in the BPMV may cause an electrical short circuit and increase the risk of fire.
The remedy
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 were mailed on October 20, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N212349181.
What this page does not include
NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
