The 2022 Chevrolet 6500HD has 3 recalls, all rated at the same severity level, with the most serious being a brake fluid leak that can cause an electrical short in the brake pressure switch and start a fire while the truck is moving or parked.
A separate brake concern involves a pressure-sensor fitting on the primary hydraulic brake line that may not be properly tightened, allowing brake fluid to escape and extending stopping distances. On the chassis side, lock nuts used in the suspension and steering joints can break and lose tension, leading to steering instability and raising the risk of losing control.
