What the notice says today
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."
The consequence
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.
The remedy
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.
What it said before
Nothing has changed while we have been watching. We last read the wording of this campaign on 17 September 2026, and it matched the copy we already held.
That copy hashes to 5a8b4013cb32ea7c8bf175d0a5c7164f…, so if it is ever edited the change is provable rather than a matter of memory.
This is one of 663 notices in the record whose component field names exterior lighting. Across that group the median wait before owners were written to was 43 days.
Last checked . No change has been recorded in the wording.
The same recall in other countries
This campaign carries a manufacturer code that also appears in another country’s register, which means the same defect was recalled there too.
- Canada: Transport Canada recall 2025357, recorded 26 June 2025 (within a week of the American filing)
Matched on 25PACF, the manufacturer’s own number for this campaign, which is the only field the registers share. Exact match, nothing paired on brand and date. The two dates are adjacent instruments rather than the same one, so a difference of a day or two means nothing.

How to cite this record
Quoting the wording on this page means quoting a version, so the date belongs in the citation:
CarsMultiverse, recall 25V436, wording as read on 17 September 2026. https://carsmultiverse.com/recall/25v436/
The copy quoted above hashes to 5a8b4013cb32ea7c8bf175d0a5c7164f…. If the notice is reworded later, that fingerprint will not match, which is how a reader checks that the quotation was of the version we say it was.
The cross-border matches used on this site are deposited as a citable dataset: doi:10.5281/zenodo.22087136. The recall wording itself is published by the national authority named above and is theirs, not ours.
The recall record and its wording are published by the US National Highway Traffic Safety Administration and are US Government public domain. The dated archive, the comparison and any before-and-after above are CarsMultiverse. How fresh every engine behind this page is, is public on the status page.
