General Motors is recalling approximately 40,428 2019-23 Chevrolet Silverado medium-duty trucks, according to the National Highway Traffic Safety Administration (NHTSA).
Models Impacted
The 2019-23 makes and models that could be at risk include:
Chevrolet Silverado 4500HD
Chevrolet Silverado 5500HD
Chevrolet Silverado 6500HD
The Risk
The brake pressure sensor assembly may leak brake fluid into the brake pressure switch and cause an electrical short-circuit. An electrical short in the brake pressure switch can overheat the circuit and increase the risk of a fire while driving or parked.
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.
Interim letters notifying owners of the safety risk are expected to be mailed on May 29, 2023. Second letters will be mailed once the remedy is available.
