General Motors is recalling approximately 40,428 Chevrolet 4500HD, 5500HD, and 6500HD Medium-Duty trucks from model years 2019 through 2023. A defect in the brake pressure sensor assembly can allow brake fluid to leak into the brake pressure switch, causing an electrical short-circuit. This short-circuit can lead to the circuit overheating and starting a fire. General Motors dealers will replace the master cylinder pressure sensor and inspect or replace the wire harness free of charge.
The electrical short-circuit in the brake pressure switch can cause the circuit to overheat, which significantly increases the risk of a vehicle fire while the truck is being driven or even when it is parked. Because of this fire risk, owners are advised to park their vehicles outdoors and away from buildings or other structures until the repair is finished.
You have 2 options:
Master cylinder pressure sensor replacement and wire harness inspection.
