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 531 complaints with NHTSA since 2015. 247 of them name 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 2021 Ford Mustang Mach-E, the 17 owners who gave an odometer reading for Electrical System reported it at a median of 30,696 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
After charging for the first time at a DC fast charge station to 80%, I resumed my trip and drove about 3 miles to merge onto the expressway, my screen panel said "safely stop now", with a turtle logo and battery icon coming on. my car then came to a complete stop within a few seconds in the middle of the on-ramp leaving me stranded.

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 22B48 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 22B48 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 22B48 cover?
The manufacturer filed it against 3 model years: 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E, 2022 Ford Transit. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
