What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2023-2025 F-Super Duty vehicles may exhibit a "Hill Start Assist Unavailable" and/or "Parking Brake Limited Function" message at vehicle start-up with diagnostic trouble codes (DTC) U0151, U023A, U0159, and/or U0146 stored in the anti-lock brake system (ABS) module. These DTCs and/or U0415 may also be present in various other modules related to "invalid data received from the ABS control module". Replacement or reprogramming of the ABS module will not resolve this condition. There is no effect to the parking brake or other vehicle functions. This does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q3 2025. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.

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.

I have about 6,000 miles on the vehicle which was purchased new. There were 2 incidents prior to 2/15/26 (the 3rd incident), but it was only this 3rd incident whereby I could identify the problem.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 53892 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 53892 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 53892 cover?
The manufacturer filed it against 12 model years: 2025 Ford F-250 Super Duty, 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2025 Ford F-350 Super Duty, 2024 Ford F-350 Super Duty, 2023 Ford F-350 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
