The short answer

NHTSA received PACCAR Incorporated’s report on Feb 15, 2023. Copied from NHTSA on Oct 25, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

Service brake failure can increase the risk of a crash.

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.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
