Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2021-2023 Ford and Lincoln vehicles may exhibit DTCs U2100 and/or U3002 stored in the cruise control module (CCM), side obstacle detection control module LH (SODL), side obstacle detection control module RH (SODR), side obstacle detection control module C (SODCMC) and/or side obstacle detection control module D (SODCMD) after a module replacement. DTC U2100 may set when the module has not been properly configured after replacement. DTC U3002 may set when the module has been configured with the incorrect VIN. To correct this condition, verify that the module storing the DTC has been installed following the applicable Workshop Manual (WSM) Removal and Installation procedure. If the DTC is still stored, download and run the Vehicle Identification Number (VIN) Write application found under Toolbox, Multi-Module tab in the Ford Diagnosis and Repair System (FDRS).

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 15 model years this bulletin names have filed 3,645 complaints with NHTSA since 2015. 927 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.
On the 2021 Ford F-150, the 32 owners who gave an odometer reading for Electrical System reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

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 51903 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 51903 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 51903 cover?
The manufacturer filed it against 16 model years across 2 brands (Ford and Lincoln): 2023 Ford Escape, 2023 Ford Expedition, 2022 Ford Expedition, 2023 Ford F-150, 2022 Ford F-150, 2021 Ford F-150 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
