Ford filed this with NHTSA as a service bulletin dated Jun 25, 2025, received Jul 1, 2025, about the electrical system. It names 2 model years (2024–2025). 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 2 model years this bulletin names have filed 56 complaints with NHTSA since 2015. 34 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.
Dash completely turned off. We could not see speed, gear, battery life, etc. See attached photo of the dash board above the steering wheel. Tried turning car off and on, tried resetting the monitor. Dealership service advisor witnessed this. The technician could not replicate it, and they did not have a solution but it is now back on.
2025 Ford Mustang Mach-E · Electrical System · filed with NHTSA Dec 20, 2025
On Thursday, May28 I was driving my 2025 Ford Mach-2 on Schrock Rd. in Columbus, Ohio at approximately 3:30 PM when the hood (the "frunk") of the car unexpectedly unlatched and opened, flying up to a vertical position and obscuring my view of traffic. I was driving in the left lane of this road at 40-45 mph.
2025 Ford Mustang Mach-E · Electrical System · filed with NHTSA Jun 3, 2026
I am reporting a serious safety defect involving the electronic front door latches on my 2024 Ford Mustang Mach E. During a 12V battery discharge, the electric latches can fail, preventing the doors from opening in the outside.
2024 Ford Mustang Mach-E · Electrical System · filed with NHTSA Aug 14, 2025
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 25-2274 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 25-2274 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 25-2274 cover?
The manufacturer filed it against 2 model years: 2025 Ford Mustang Mach-E, 2024 Ford Mustang Mach-E. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: 2024-2025 Mustang Mach-E: built on or before 4 Apr 2025 — the build date is on the certification label in the driver’s door jamb.
