2 recalls covering model years 2021. To check whether your vehicle is affected, look up your 17-character VIN at nhtsa.gov/recalls — a recall may apply only to some vehicles of a given year.
A sensor that measures brake pressure may leak brake fluid into a nearby switch. That leak can cause an electrical short, which can overheat and raise the risk of a fire, whether the truck is being driven or parked.
⚠ NHTSA advises: park outside and away from structures (fire risk).
Certain 2021-2022 Chevrolet 4500HD, 5500HD and 6500HD trucks have hex flange lock nuts in the steering and suspension joints that weren't heat-treated correctly during manufacturing. Because of this, these nuts may break. If a nut breaks, the joint it was holding together can lose tension, which can affect how the steering works. Dealers will replace the affected lock nuts as needed to fix this, free of charge.
