Ford filed this with NHTSA as a service bulletin dated Jul 30, 2024, received Aug 6, 2024. It names 2 model years (2023).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.
Some 2023 Mustang Mach-E/e-Transit vehicles built on or before 09-Dec-2023 may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P0B3B, P0B40, P0B45, P0B4A, P0B4F, P0B54, P0B59, and/or P0B5E stored in the battery energy control module (BECM). Vehicle may also exhibit a no start condition, inability to charge the battery and/or a "Stop Safely Now" message displayed in the instrument panel cluster (IPC). This may be due to an intermittent condition in the BECM flexible printed circuit cable.
Trouble codes it names: P0B3B P0B40 P0B45 P0B4A P0B4F P0B54 P0B59 P0B5E

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 52757 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 52757 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 52757 cover?
The manufacturer filed it against 2 model years: 2023 Ford E-Transit, 2023 Ford Mustang Mach-E. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
