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 2025-2026 Mustang vehicles built on 01-Jun-2025 and through 25-Apr-2026 may exhibit a chirp and/or rattle noise from the left side of the instrument panel. This may be due to the heating, ventilation and air condition (HVAC) control module lower fastener making contact with the instrument panel frame directly behind the fastener. To correct the condition, remove the HVAC control module. Refer to Workshop Manual (WSM), Section 412-00 > General Information > Removal and Installation > Heating, Ventilation and Air Conditioning (HVAC) Control Module. Installing the lower fastener without the module will show where it is making contact with the instrument panel frame. If contact is present, use flock tape (Rotunda part number 164-R4903) to insulate the instrument panel frame from the end of the lower fastener. Reinstall the HVAC module. For claiming, use causal part 19980 and labor operations 19700D and 19700D16.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54912 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 54912 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 54912 cover?
The manufacturer filed it against 2 model years: 2026 Ford Mustang, 2025 Ford Mustang. 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: 2025-2026 Mustang: built 1 Jun 2025 – 25 Apr 2026 — the build date is on the certification label in the driver’s door jamb.
