What it says4/29/2025: Campaign A software update is available for 520EV and 579EV Battery Electric Vehicles. NHTSA’s full summary ↓
Peterbilt filed this with NHTSA as a service campaign dated Apr 30, 2025, received May 6, 2025, about the electrical system. It names 14 model years (2019–2025). 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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Peterbilt’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.

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 46-016 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 46-016 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 46-016 cover?
The manufacturer filed it against 14 model years: 2019 Peterbilt 520, 2020 Peterbilt 520, 2021 Peterbilt 520, 2022 Peterbilt 520, 2023 Peterbilt 520, 2024 Peterbilt 520 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 26 Feb 2020 – 5 Nov 2024 — the build date is on the certification label in the driver’s door jamb.
