What's wrong

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.

Why it matters

Service brake failure can increase the risk of a crash.

The fix

Dealers will add a pedal restraint bracket, free of charge. Owner notification letters were mailed April 7, 2023. Owners may contact Kenworth's customer service at 1-425-828-588 and Peterbilt's customer service at 1-940-591-4220. PACCAR's numbers for this recall are 23KWB and 23PBB.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
