Ford filed this with NHTSA as a service bulletin dated Jun 6, 2024, received Jun 10, 2024, about the service brakes. It names 2 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 communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some 2023-2024 F-150 non-hybrid/non-Lightning vehicles built on or after 01-Mar-2023 may exhibit an illuminated battery malfunction indicator and/or illuminated ABS malfunction indicator which may be accompanied by a Check Brake System message and/or 12V Battery State Of Charge Low message in the instrument panel cluster (IPC) with diagnostic trouble code (DTC) U3003:16 stored in the ABS module. This may be due to the state of charge of the battery. The Workshop Manual (WSM) has recently been updated with improved diagnostics for this condition. Refer to the WSM, Section 206-09 Anti-Lock Brake System (ABS) and Stability Control, Diagnosis and Testing, Anti-Lock Brake System (ABS) and Stability Control - Electric, Pinpoint Tests, Pinpoint Test A: ABS Voltage Supply Concerns for applicable diagnostics.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 745 complaints with NHTSA since 2015. 237 of them name Electrical System, Service Brakes — 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 2023 Ford F-150, the 15 owners who gave an odometer reading for Service Brakes reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The parking brake has repeatedly engaged without action from the owner/operator. This seems to happen at random. The dash warning light does show upon occurrence. There is no known cause for, or understanding of, this malfunction. The Ford certified dealer could not confirm as it did not occur under their supervision when serviced.

My 2023 Ford F-150 keeps having an issue where the electronic parking brake will engage while I'm driving. The issue has happened to me at least five times. Luckily for me I was going between 5-10 miles per hour and did not have any vehicles around me.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52594 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 52594 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 52594 cover?
The manufacturer filed it against 2 model years: 2024 Ford F-150, 2023 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built on or after 1 Mar 2023 — the build date is on the certification label in the driver’s door jamb.
