Freightliner service campaign SF691
What it saysRevised Field Service Campaign for M2 Plus Work Brake. NHTSA’s full summary ↓
Freightliner filed this with NHTSA as a service campaign dated Oct 23, 2024, received Jun 28, 2024, about the service brakes — 5 documents under this number: SF691-DLR LTR (2 filings), SF691-Bulletin (2 filings), SF691-OWN LTR. It names 2 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

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 Freightliner SF691 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 SF691 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 SF691 cover?
The manufacturer filed it against 2 model years: 2024 Freightliner Business Class M2, 2025 Freightliner Business Class M2. 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: 2024-2025 Business Class M2: built on or after 23 Mar 2023 — the build date is on the certification label in the driver’s door jamb.
