Ford bulletin ACM-26.S
Ford filed this with NHTSA as a over-the-air update dated Jun 10, 2026, received Jun 4, 2026, about the unknown or other — 3 documents under this number: ACM-26. S F-150, ACM-26. S MachE, ACM-26. S Escape. It names 5 model years (2023–2024). A over-the-air update 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.
