2023–2024 Kenworth T280, Kenworth T380, Kenworth T480 +more: Power Train recall

NHTSA campaign 23V504000 · 72 units potentially affected · filed Jul 21, 2023

What's wrong

PACCAR Incorportated (PACCAR) is recalling certain 2023-2024 Peterbilt 536, 537, 548, 2023-2024 Kenworth T280, T480, and 2024 Kenworth T380 vehicles. The adhesive thread-lock may not have been applied to the four flange mounted yoke bolt threads, allowing the driveline fasteners to loosen.

Why it matters

Loose fasteners may allow the driveline to separate from the truck, increasing the risk of a crash.

The fix

Dealers will apply adhesive thread-lock and replace the fasteners, free of charge. Owner notification letters are expected to be mailed September 19, 2023. Owners may contact PACCAR's customer service at 1-425-828-5888 (Kenworth) or 1-940-591-4220 (Peterbilt). PACCAR's numbers for this recall are 23KWE and 23PBE.

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.
