## What is 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.

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.
