Component: Service brakes

PACCAR Incorporated (PACCAR) is recalling certain 2021-2024 Kenworth T280, T380, T480, Peterbilt 536, 537, and 548 vehicles. When the brake pedal is fully applied and then released rapidly, the pedal plunger that connects the brake pedal to the brake valve may become disconnected, causing the service brakes to fail.

Status: NHTSA lists Apr 6, 2023 as the owner-notification date for this campaign.
