Ford bulletin TSB 25-2575
What it saysThis article supersedes TSB 24-2104 to update the vehicle model years affected. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Nov 28, 2025, received Dec 2, 2025, about the electrical system. It names 5 model years (2021–2025). A service bulletin 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 (2 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 960 complaints with NHTSA since 2015. 107 of them name Electrical System, Suspension — 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.
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 TSB 25-2575 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 TSB 25-2575 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 TSB 25-2575 cover?
The manufacturer filed it against 5 model years: 2025 Ford Bronco, 2024 Ford Bronco, 2023 Ford Bronco, 2022 Ford Bronco, 2021 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
