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 equipped with a 5.0L or 2.3L engine and built on 15-Aug-2025 and through 01-Dec-2025 may exhibit various drivability symptoms and/or have diagnostic trouble codes (DTC) stored in the powertrain control module (PCM) related to throttle/pedal position circuits. This may be caused by a spread terminal at the PCM connector. Inspect for loose fitting terminals at C1551B for 2.3L vehicles, and C175B on 5.0L vehicles. Refer to the appropriate Wiring Diagram Cells for circuit identification and wiring repair information. Wire terminal repair kit part DU2Z-14474-CA is recommended for this repair. Refer to Wiring Diagram, Cell 005 for repair procedures. For claiming, use causal part 14290 and labor operations 12651D, 12651D45 and 12651D45WR.

Read by machine from the document NHTSA serves (1 page), read Sep 29, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 28 complaints with NHTSA since 2015. 12 of them name Electrical System, Power Train, Vehicle Speed Control — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
Recalls on 2024 Ford Mustangs: On 09/22/2026, at approximately 11:34AM, my Ford Mustang suffered a catastrophic malfunction. When I was braking on the offramp, the brakes did not engage and remained firm and unresponsive. The car immediately accelerated, despite my efforts on the brakes accompanied by the use of the emergency brake.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 55072 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 55072 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 55072 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 15 Aug 2025 – 1 Dec 2025 — the build date is on the certification label in the driver’s door jamb.
