Ford filed this with NHTSA as a service bulletin dated May 3, 2024, received May 17, 2024. It names 3 model years (2021–2023). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some 2021-2023 Mustang Mach-E vehicles built on or before 21-Apr-2023 may exhibit a false alarm activation and/or warning message in the FordPass application when the doors are locked. This may be due to the software in the door latch control module E (DCME), door latch control module F (DCMF), door latch control module G (DCMG) and/or door latch control module H (DCMH). To correct the condition, download and run the door control module software update application for each module one at a time using the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 58219A65 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.

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 Ford SSM 52504 a recall?
No. A service bulletin 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, or on its page here.
Is the SSM 52504 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 52504 cover?
The manufacturer filed it against 3 model years: 2023 Ford Mustang Mach-E, 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E. 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: 2021-2023 Mustang Mach-E: built on or before 21 Apr 2023 — the build date is on the certification label in the driver’s door jamb.
