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. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782.
The hazard
Water in the brake pressure modulator valve (BPMV) may cause an electrical short circuit and increase the risk of fire. This results from bolts that attach the BPMV assembly not being properly tightened during vehicle assembly, which fails to seal the sub-assemblies and allows water intrusion.
