The defect
PACCAR Incorporated (PACCAR) is recalling certain 2024-2026 Kenworth T480, T680, T880, W990, Peterbilt 520, 536, 537, 548, 567, 579, 589, 2025 Kenworth T180, Peterbilt 535, 2025-2026 Kenworth T280, T380 and L770 vehicles. The tail brake light, upper and lower beam headlights, reverse light, and turn signal may not illuminate as intended. In addition, the lift axles, if lowered, may revert to a raised position, or oscillate up and down when the signal warning lights are activated. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices and Associated Equipment."
What it can cause
Delayed and unsteady headlights can result in insufficient illumination of the road, decreasing the driver's visibility and increasing the risk of a crash. In addition, an unexpected position change of the lift axles may increase the risk of injury.
What the dealer does
Dealers will update the VCU software, free of charge. Owner letters were mailed August 19, 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 number for this recall is 25PACF.

The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.

Which vehicles

A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup.

How this campaign compares

At 56,260 vehicles this is a bigger campaign than 90% of the 18,761 vehicle recalls with a published size filed from 1995 up to this one. The middle campaign among them covers 469. It covers model years 2024 to 2026, so the oldest vehicles on it were one model year old when the defect was reported to NHTSA.

Kenworth vehicles have been recalled over the exterior lighting 12 times before this, most recently in January 2025 as 25V041000. That is not evidence the earlier repair failed.

This site holds the complaint record for 1 of the 40 model years the campaign names. Their owners have filed 5 complaints with NHTSA, 3 of them before this campaign was filed.

The vehicles on this campaign carry 27 other recalls published here, the newest being: 26V700000 (fuel system, diesel), 26V442000 (service brakes, air), 26V022000 (steering), 25V795000 (service brakes, air).

Check your own car

A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
