What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2020-2022-Corsair, 2021-2023 Nautilus, 2020-2024 Navigator/Aviator, and 2021-2024 Mustang Mach-E vehicles equipped with phone-as-a-key may exhibit various phone-as-a-key concerns with diagnostic trouble codes (DTC) U200D:15, U200E:15, U200F:15, B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 stored in the remote function actuator (RFA) module. If any of these DTCs are detected during diagnostics, clear the DTCs, reprogram the RFA to the latest software level and start a new Ford Diagnosis and Repair System (FDRS) session. Verify that DTCs are no longer present. If only the B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 DTCs return in the RFA after a self-test, follow normal Workshop Manual (WSM) diagnostics in Section 419-01. Repair as necessary outside of this article. For claiming, use causal part 14G617 and labor operations 12651D and 12651D4.

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 19 model years this bulletin names have filed 1,105 complaints with NHTSA since 2015. 449 of them name Electrical System, Structure — 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 Mustang Mach-E, the 17 owners who gave an odometer reading for Electrical System reported it at a median of 30,696 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

2022 Lincoln Navigator · Electrical System · filed with NHTSA Jul 11, 2023
The collision warning doesn't warn sometimes. Nothing goes off when Im approaching and or have slammed on my breaks to avoid a collision. Sometimes it goes off at a great distance when it doesn't make sense to go off. I just bought the car used and have noticed this a lot. Also sometimes lane departure corrects and sometimes it doesn't.

2022 Lincoln Nautilus · Electrical System · filed with NHTSA Mar 19, 2026
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 579.5Is Ford SSM 54555 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 54555 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 54555 cover?
The manufacturer filed it against 19 model years across 2 brands (Ford and Lincoln): 2024 Ford Mustang Mach-E, 2023 Ford Mustang Mach-E, 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E, 2024 Lincoln Aviator, 2023 Lincoln Aviator and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
