What's wrong?
The primary hydraulic brake line assembly on the 2022 Chevrolet 4500HD, 5500HD, and 6500HD carries brake fluid under pressure. A pressure-sensor fitting threads into that line and lets the brake system read pressure while keeping the fluid sealed inside. When the brake pedal is pressed, the system depends on that sealed line to hold pressure.
On affected trucks, the pressure-sensor fitting was not tightened to the required force. The supplier print was missing the tightening specification after a change to the assembly, so the fitting left production without the correct clamp load. A loose fitting lets brake fluid leak from the primary hydraulic brake line assembly. If enough fluid is lost, brake pressure drops and the truck needs more distance to stop.
Drivers can notice a soft or low brake pedal before the leak becomes worse. The brake warning light can come on, and brake fluid can appear on the ground or in the engine compartment.

What happens at the repair
At the dealer, a Chevrolet technician tightens the brake pressure switch, bleeds the brake system, and tops off the brake fluid. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because all covered vehicles are under warranty. Ask the Chevrolet service desk how warranty coverage applies if you have prior brake repair paperwork.
