What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 670 complaints with NHTSA since 2015. 444 of them name Power Train, Electrical System — 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 2020 Ford Expedition, the 55 owners who gave an odometer reading for Power Train reported it at a median of 65,600 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 23-2256 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 TSB 23-2256 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 TSB 23-2256 cover?
The manufacturer filed it against 2 model years: 2021 Ford Expedition, 2020 Ford Expedition. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
