Ford filed this with NHTSA as a service bulletin dated Jun 29, 2023, received Jul 3, 2023, about the engine. It names 3 model years (2023).

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51754 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 51754 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 51754 cover?
The manufacturer filed it against 3 model years: 2023 Ford Bronco, 2023 Ford Explorer, 2023 Ford Ranger. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
