PACCAR Incorporated: Power Train › Driveline
PACCAR Incorporated reported this defect to federal regulators on Jul 21, 2023 and put the number of vehicles at risk at 72. The repair is free for as long as the recall stands.
The defect
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.
The risk
Loose fasteners may allow the driveline to separate from the truck, increasing the risk of a crash.
The remedy
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.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 23V504000.
