What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025-2027 Expedition/Navigator vehicles may exhibit an intermittent electronic static/buzzing/screeching/humming noise from the front audio speakers that changes with engine RPM. This may be due to a software concern with the active noise cancellation system. Replacement of audio system components will not resolve this condition. Advise customers that engineering is currently investigating and developing a software solution that is expected by the end of Q1 2027.<br/ ><br /> If experienced, customers can temporarily clear the abnormal noise condition by stopping the vehicle in a safe location, placing the transmission in park, then pressing the audio volume control/power button 5 times until the vehicle center screen begins to reboot. The condition should also be temporarily resolved after parking the vehicle with the ignition off, doors locked, and keys moved more than 15 feet away from the vehicle allowing all systems to go to sleep for at least 15 minutes.<br/ ><br /> If a vehicle exhibits this condition, click on the "Submit Global Concern Report (GCR)" link at the upper right of the Professi

Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 61 complaints with NHTSA since 2015. 9 of them name Electrical System — 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.
This vehicle has been returned to service 5 times. It is currently in service for the same 4 issues that it was taken to service for the very first time on 12/10/2025. This includes inappropriate braking on the interstate, driver window malfunction, the key intermittently stops working, and the connectivity does not regularly work.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 55258 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 55258 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 55258 cover?
The manufacturer filed it against 6 model years across 2 brands (Ford and Lincoln): 2027 Ford Expedition, 2026 Ford Expedition, 2025 Ford Expedition, 2027 Lincoln Navigator, 2026 Lincoln Navigator, 2025 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
