What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2021 F-150 vehicles may exhibit an erroneous diagnostic trouble code (DTC) U2404:92 stored in the gateway module (GWM) after an over the air (OTA) update was performed or the GWM software was updated using the Ford Diagnosis And Repair System (FDRS). This may be due to various software parameters within the GWM. If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the GWM operation, this DTC should be disregarded. This DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability.
Trouble codes it names: U2404

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 1,309 complaints with NHTSA since 2015. 179 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54764 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 54764 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 54764 cover?
The manufacturer filed it against 1 model year: 2021 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
