The defect
PACCAR Incorporated (PACCAR) is recalling certain 2025 Kenworth T180, Peterbilt 535, 567, 2025-2026 Kenworth T280, 2023-2026 Kenworth T380, 2024-2026 Kenworth T480, 2024-2026 Peterbilt 536, 537, and 548 trucks. The exterior lighting switch may fail, resulting in the hazard lights and the instrument display back-light brightness adjustment not functioning. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 108, "Lamps, Reflective Devices and Associated Equipment."
The risk
Inoperative hazard lights cannot alert other drivers as intended. In addition, the inability to adjust the brightness on the instrument panel display can make it difficult to see critical safety information or distract the driver. Both scenarios can increase the risk of a crash.
The remedy
Dealers will update the vehicle cab controller unit (VECU) software, free of charge. Owners are advised that a non-responsive switch can be temporarily reset by a key cycle. Owner notification letters were mailed March 26, 2025. Owners may contact Kenworth's customer service at 1-425-828-5888 and Peterbilt's customer service at 1-940-591-4220. PACCAR's numbers for this recall are 25KWB and 25PBB.

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 25V041000.
