Ford filed this with NHTSA as a manufacturer communication dated Apr 29, 2026, received Apr 30, 2026, about the electrical system. It names 23 model years across Ford and Lincoln (2016–2020). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

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 21 model years this bulletin names have filed 15,165 complaints with NHTSA since 2015. 1,208 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 2017 Ford Escape, the 81 owners who gave an odometer reading for Electrical System reported it at a median of 39,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

This vehicle is equipped with a feature that shuts the engine and ignition off after 30 minutes of idle without driver interaction. These vehicles have "up-fitter switches" which can be tied to things like auxiliary warning lights. When the vehicle shuts down, the headlights/tail lights turn off as well as power to any auxiliary loads.

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 25H05 S1 a recall?
No. A manufacturer communication 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 25H05 S1 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 25H05 S1 cover?
The manufacturer filed it against 23 model years across 2 brands (Ford and Lincoln): 2017 Ford Escape, 2020 Ford F-150, 2019 Ford F-150, 2018 Ford F-150, 2017 Ford F-150, 2019 Ford F-250 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
