Ford bulletin 25H05
Ford filed this with NHTSA as a manufacturer communication dated Nov 19, 2025, received Dec 3, 2025, about the electrical system. It names 21 model years (2016–2021). 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; the full text comes from the manufacturer or a dealer. 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 25H05 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 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 cover?
The manufacturer filed it against 21 model years: 2021 Ford E-Series, 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.
