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 15 model years this bulletin names have filed 10,329 complaints with NHTSA since 2015. 3,323 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 2018 Ford F-150, the 334 owners who gave an odometer reading for Power Train reported it at a median of 60,350 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2019 Ford Explorer. The contact stated while driving at various speeds, the horn failed to work when depressed. The contact stated no warning light was illuminated. The vehicle was not taken to a local dealer or an independent mechanic for diagnosis or repairs. The manufacturer had not been informed of the failure.
2019 Ford Explorer · Electrical System · filed with NHTSA Mar 26, 2021 · ODI 11404975
When driving car lost all electrical functions, power steering, radio, lights, etc. I had it towed to service and they said nothing came up in diagnostics or error codes. I picked the car up and within a couple weeks it started happening again. Before it was only happening when I sat idle for a period of time and then started moving.
2017 Ford Explorer · Electrical System · filed with NHTSA Jun 14, 2017 · ODI 10995127
I purchased the car a week ago from a dealership and sadly that the car was as is. At the time nothing was wrong with the car, and 2 days later after the car APIM system started malfunctioning, I restarted the system and that did not work. I took to a dealership and they did the same thing I did and it is still the same.

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.

Is the 25E10-S1 repair free?
A emissions communication is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
