Ford bulletin SSM 54363

What it saysSome 2021-2025 Expedition/Navigator/F-150/F-Super Duty/F-53 Motorhome/F59 Commercial Stripped Chassis/F-650/F-750/Transit vehicles equipped with a 2.7L/3.5L (non hybrid)/6.8L/7.3L engine and 2021-2026 E-Series… NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Nov 10, 2025, received Nov 13, 2025, about the engine. It names 65 model years across Ford and Lincoln (2020–2026). 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 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.

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 database

Owners of the 42 model years this bulletin names have filed 4,734 complaints with NHTSA since 2015. 1,646 of them name Power Train, Engine — 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.

On the 2021 Ford F-150, the 88 owners who gave an odometer reading for Power Train reported it at a median of 58,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The contact owns a 2024 Ford F-350. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer informed the contact that a software update had been completed on the TCM.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Ford SSM 54363 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 54363 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 54363 cover?

The manufacturer filed it against 65 model years across 2 brands (Ford and Lincoln): 2026 Ford E-Series, 2025 Ford E-Series, 2024 Ford E-Series, 2023 Ford E-Series, 2022 Ford E-Series, 2021 Ford E-Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
