SERVICE BRAKES, HYDRAULIC
- The defect
- General Motors. LLC (GM) is recalling certain 2019-2023 Chevrolet 4500HD, 5500HD, and 6500HD Medium-Duty trucks. The brake pressure sensor assembly may leak brake fluid into the brake pressure switch and cause an electrical short-circuit.
- What it can cause
- An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.
- What the dealer does
- Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the master cylinder pressure sensor and inspect the wire harness, replacing it, if necessary, free of charge. Owner notification letters were mailed July 11, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N222375270.
- 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.

How this campaign compares
At 40,428 vehicles this is a bigger campaign than 88% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2019 to 2023, so the oldest vehicles on it were 4 model years old when the defect was reported to NHTSA.
Chevrolet vehicles have been recalled over the service brakes, hydraulic 47 times before this, most recently in September 2021 as 21V758000. That is not evidence the earlier repair failed.
