2021 Chevrolet Silverado 2500HD Control Module recall 21V758000
Safety recall
Symptoms / what can happen
Water in the BPMV may cause an electrical short circuit and increase the risk of fire.

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.
