Peterbilt service campaign 46-013
What it saysCertain Peterbilt 579EV and 520EV Battery Electric Vehicles were built prior to the availability of certain labels and Low Voltage Distribution System (LVDS) Components. NHTSA’s full summary ↓
Peterbilt filed this with NHTSA as a service campaign dated Feb 5, 2025, received Mar 4, 2025, about the electrical system. It names 6 model years (2021–2023). 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.
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.
Certain Peterbilt 579EV and 520EV Battery Electric Vehicles were built prior to the availability of certain labels and Low Voltage Distribution System (LVDS) Components. Affected chassis will be inspected and necessary components will be installed.

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.
Model years it names
Source: as the manufacturer filed themAlso filed against: 2021 Peterbilt 520; 2022 Peterbilt 520; 2023 Peterbilt 520; 2021 Peterbilt 579; 2022 Peterbilt 579; 2023 Peterbilt 579.
None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.

Common questions
Source: NHTSA, 49 CFR 579.5Is Peterbilt 46-013 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 46-013 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 46-013 cover?
The manufacturer filed it against 6 model years: 2021 Peterbilt 520, 2022 Peterbilt 520, 2023 Peterbilt 520, 2021 Peterbilt 579, 2022 Peterbilt 579, 2023 Peterbilt 579. 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 26 Feb 2020 – 21 Feb 2022 — the build date is on the certification label in the driver’s door jamb.
