What the defect is
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."
What could happen
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.
What gets fixed
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.

Your rights
A safety recall repair is free. Under US federal law the manufacturer must fix a safety defect at no cost to you — no charge for parts, labor or diagnosis — whether or not you are the original owner. A dealer cannot charge you for recall work, and cannot require you to have bought the vehicle from them.
That entitlement is not unlimited. It applies where the vehicle was first sold less than 15 years before the recall was announced — 5 years for tires. Past that a manufacturer may still do the repair free of charge, and many do, but they are no longer obliged to. This recall was reported on 29 January 2025.
To arrange the repair, contact any franchised dealer for the brand. If a dealer refuses the work or tries to charge for it, you can report that to NHTSA at nhtsa.gov/recalls or on 1-888-327-4236.

Everything on this page — the models listed, the build dates and the repair figures — comes from the manufacturer's filing to NHTSA and describes the vehicle line as a whole, not any individual car. Only the manufacturer can confirm whether a specific vehicle is affected, and whether its recall work has already been carried out. Check yours by VIN and read the official notice at nhtsa.gov/recalls.
Additional notes
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 nhtsa.gov.
Check your own vehicle
This page describes the recall, not any one car. To see which recalls cover a specific vehicle, search by make, model and year.
A VIN lookup here identifies your vehicle and shows recalls issued for that make, model and year. It cannot tell you what is still open on your individual car - only the manufacturer knows that. Search by VIN instead, or check your VIN at nhtsa.gov for whether a recall is still open on your individual car.
