Reported 2023-04-13 · Campaign 23V266000 · Model years: 2021
A part that senses brake fluid pressure can leak fluid into the electrical switch next to it. The fluid lets electricity go where it should not, which overheats the wiring and can start a fire. This can happen while you are driving the truck or while it sits parked. The dealer replaces the pressure sensor on the master cylinder and looks over the wiring, replacing that too if it has been damaged. All of this is done at no cost to you.
⚠ NHTSA advises: park outside and away from structures (fire risk).
Reported 2022-11-23 · Campaign 22V874000 · Model years: 2021
Some 2021-2022 Chevrolet 4500HD, 5500HD and 6500HD trucks left the factory with locking nuts that hold parts of the suspension and steering together. Those nuts were not hardened correctly when they were made, so they can snap. If one breaks, the joint it was holding loses its grip and the truck can start to wander or feel unstable when you steer. Your dealer will check the nuts and replace any that need it.
