Ford filed this with NHTSA as a service bulletin dated Jun 7, 2024, received Jun 10, 2024. It names 8 model years (2023–2024).

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

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2023-2024 F-Super Duty vehicles equipped with a keyed ignition may exhibit a "Vehicle May Not Start/Restart Service Now" message in the instrument panel cluster (IPC) with diagnostic trouble code (DTC) U300A:01 stored in the body control module (BCM). This may be due to an obstruction of the ignition key due to a mispositioned grommet around the ignition lock cylinder. To correct this condition, reseat the grommet. This may require full or partial removal of the center instrument panel trim which the grommet seats into. Refer to Workshop Manual (WSM), Section 501-12. Once complete, make sure there is no restriction to movement and retest. If the condition persists, refer to normal diagnostics in WSM, Section 211-05.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52606 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 52606 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 52606 cover?
The manufacturer filed it against 8 model years: 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2024 Ford F-350 Super Duty, 2023 Ford F-350 Super Duty, 2024 Ford F-450 Super Duty, 2023 Ford F-450 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
