Read by machine from the document NHTSA serves (13 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 3 model years this bulletin names have filed 90 complaints with NHTSA since 2015. 7 of them name Steering — 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.
I was driving the truck and applied the brakes to slow down for a turn, the anti-lock brake system activated and I lost the power steering and power brakes. There is steering fluid all over the engine so apparently either a line broke or the reservoir broke.

My rear camera repeatedly freezes in a picture or does not come on. My steering has lost most of its fluid twice and I was told this was normal air bleading out. My truck has stopped itself while traveling down the road without any obstruction.

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 23B55 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 23B55 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 23B55 cover?
The manufacturer filed it against 7 model years: 2023 Ford F-250 Super Duty, 2023 Ford F-350 Super Duty, 2023 Ford F-450 Super Duty, 2023 Ford F-550 SD, 2023 Ford F-600 SD, 2023 Ford F-650 SD and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
