SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE
- The defect
- 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 it can cause
- Water in the BPMV may cause an electrical short circuit and increase the risk of fire.
- What the dealer does
- 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.
- NHTSA's note
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .
How this campaign compares
At 3,241 vehicles this is a bigger campaign than 71% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2021 to 2022, and the defect was reported to NHTSA in 2021, at or before the oldest model year it covers — as current as a recall gets.
Chevrolet vehicles have been recalled over the service brakes, hydraulic 46 times before this, most recently in July 2021 as 21V579000. That is not evidence the earlier repair failed.
This site holds the complaint record for all 8 model years the campaign names. Their owners have filed 387 complaints with NHTSA, 9 of them before this campaign was filed. 1 of those name the service brakes, hydraulic, the system this recall is about — a count of complaints, not of this defect.

Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
