SERVICE BRAKES, HYDRAULIC

Issued by General Motors, LLC · Reported Apr 13, 2023 · 40,428 vehicles affected

What's wrong

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.

Consequence

An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.

Remedy

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.
