Ford filed this with NHTSA as a manufacturer communication dated Jul 26, 2025, received Aug 2, 2025, about the engine. It names 4 model years (2025). 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.

Read by machine from the document NHTSA serves (8 pages), read Sep 30, 2026. A part number is shown only where it matches Ford’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 214 complaints with NHTSA since 2015. 76 of them name Electrical System, Engine — 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.
The contact owned a 2025 Ford Bronco. The contact stated while driving 30 MPH, another driver pulled closer to the vehicle and honked to get the contact's attention. The contact stated that upon rolling down the window, the contact noticed flames coming from the front driver's side wheel well. There was no warning light illuminated.

2025 Ford Ranger · Electrical System · filed with NHTSA Jun 4, 2026
This vehicle had an open safety recall at the time the dealership sold it to me. The recall existed before the sale and the dealership knew or should have known about it. The dealer submitted loan paperwork and accepted funding but never delivered the vehicle to me. I was not informed of the open recall before signing.

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 25P20 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 25P20 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 25P20 cover?
The manufacturer filed it against 4 model years: 2025 Ford Bronco, 2025 Ford Explorer, 2025 Ford Mustang, 2025 Ford Ranger. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
