PACCAR service campaign 25KWD 25PBD
What it saysAdditional US chassis have been added, along with additional Canadian chassis under identical safety recall 26PACB. NHTSA’s full summary ↓
PACCAR filed this with NHTSA as a service campaign dated Jul 2, 2026, received Jul 20, 2026, about the electrical system. It names 18 model years across Kenworth and Peterbilt (2020–2026). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
One page for every brand it was filed under. Each brand’s bulletins: Kenworth · Peterbilt.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Additional US chassis have been added, along with additional Canadian chassis under identical safety recall 26PACB.

Read by machine from the document NHTSA serves (17 pages), read Sep 30, 2026. A part number is shown only where it matches PACCAR’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote.
The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is PACCAR 25KWD 25PBD a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the 25KWD 25PBD repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 25KWD 25PBD cover?
The manufacturer filed it against 18 model years across 2 brands (Kenworth and Peterbilt): 2020 Kenworth K270, 2021 Kenworth K270, 2022 Kenworth K270, 2023 Kenworth K270, 2024 Kenworth K270, 2025 Kenworth K270 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built 21 Oct 2019 – 25 Jul 2024; built 2 Oct 2020 – 7 May 2025 — the build date is on the certification label in the driver’s door jamb.
