What it saysCertain Kenworth EMY 2022 T680, T880 and W990 chassis may not contain an EAS operator’s manual in the vehicle’s glovebox literature packet. NHTSA’s full summary ↓
Kenworth filed this with NHTSA as a service campaign dated Sep 23, 2026, received Sep 29, 2026. It names 9 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

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 Kenworth 9-049 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 9-049 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 9-049 cover?
The manufacturer filed it against 9 model years: 2021 Kenworth T680, 2022 Kenworth T680, 2023 Kenworth T680, 2021 Kenworth T880, 2022 Kenworth T880, 2023 Kenworth T880 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 20 Dec 2021 – 23 Sep 2026 — the build date is on the certification label in the driver’s door jamb.
