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 9 model years this bulletin names have filed 211 complaints with NHTSA since 2015. 29 of them name Power Train, Vehicle Speed Control — 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.
The contact owns a 2024 Ford F-350. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer informed the contact that a software update had been completed on the TCM.

Less than 4000 miles- first transmission failed while pulling a large trailer- ford replaced the transmission and the new transmission, only 200 miles later did the same thing when pulling a trailer, up hill. It throws the transmission into 10th gear and you loose all power, Check engine light comes on and it slams back into 4th gear.

This is the third time I have had this issue. I will be driving my truck and will out of nowhere get a warning on the dash that says: “Pre-Collision Assist not available” then after that happens I will not be able to set the cruise control. This can only be fixed by a trip to the dealer ship and usual takes 10-15 days to get fixed.

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 53994 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 53994 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 53994 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.
