## What is wrong

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.


## What can happen

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.
