PACCAR service campaign 46-025
What it saysSoftware updates are available for certain Peterbilt Model 220 BEVs that experience battery pack cell imbalances. NHTSA’s full summary ↓
PACCAR filed this with NHTSA as a service campaign dated Sep 30, 2026, received Mar 5, 2026, about the electrical system — 3 documents under this number. It names 14 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.

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 46-025 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 46-025 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 46-025 cover?
The manufacturer filed it against 14 model years across 2 brands (Kenworth and Peterbilt): 2020 Kenworth K270, 2023 Kenworth K270, 2024 Kenworth K270, 2025 Kenworth K270, 2026 Kenworth K270, 2023 Kenworth K370 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 18 Mar 2021 – 28 Oct 2024 — the build date is on the certification label in the driver’s door jamb.
