Western Star service campaign SF705

Western Star filed this with NHTSA as a service campaign dated Jan 21, 2025, received Jan 3, 2025, about the fuel/propulsion system — 5 documents under this number: SF705-DLR LTR, SF705-Bulletin, SF705-OWN LTR. It names 6 model years (2024–2025). 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.

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 them

Also filed against: 2024 Western Star 47X; 2025 Western Star 47X; 2024 Western Star 49X; 2025 Western Star 49X; 2024 Western Star 57X; 2025 Western Star 57X.

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 579.5

Is Western Star SF705 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 SF705 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 SF705 cover?

The manufacturer filed it against 6 model years: 2024 Western Star 47X, 2025 Western Star 47X, 2024 Western Star 49X, 2025 Western Star 49X, 2024 Western Star 57X, 2025 Western Star 57X. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
