The 2022 Chevrolet 5500HD has 3 recalls, the most serious being a brake pressure sensor assembly that can leak fluid into an electrical switch, creating a fire risk while the truck is moving or parked.
Two other recalls involve the braking and steering systems. A separate brake fluid leak can develop at the primary hydraulic brake line's pressure-sensor fitting if it was not tightened correctly, which extends stopping distances and raises the risk of a crash. On the steering side, lock nuts used in suspension and steering joints can break and lose tension, causing steering instability.
