PACCAR service campaign 46-022

What it saysCertain Model 220, K270, and K370 BEV chassis are broadcasting incorrect VINs to PACCAR Solutions. NHTSA’s full summary ↓

PACCAR filed this with NHTSA as a service campaign dated Feb 26, 2026, received Mar 5, 2026, about the electrical system. It names 12 model years across Kenworth and Peterbilt (2022–2025). 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 communication
Built 1 Dec 2020 – 25 Jul 2024 “Manufactured between 12/01/2020 and 07/25/2024”
Built 25 Feb 2021 – 29 Jan 2024 “Manufactured between 02/25/2021 and 01/29/2024”

What 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.

Certain Model 220, K270, and K370 BEV chassis are broadcasting incorrect VINs to PACCAR Solutions.

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 579.5

Is PACCAR 46-022 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 46-022 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 46-022 cover?

The manufacturer filed it against 12 model years across 2 brands (Kenworth and Peterbilt): 2022 Kenworth K270, 2023 Kenworth K270, 2024 Kenworth K270, 2025 Kenworth K270, 2022 Kenworth K370, 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 1 Dec 2020 – 25 Jul 2024; built 25 Feb 2021 – 29 Jan 2024 — the build date is on the certification label in the driver’s door jamb.
