Ford filed this with NHTSA as a service bulletin dated Jun 9, 2025, received Jun 10, 2025, about the power train. It names 4 model years (2023–2024). 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 (7 pages), read Sep 29, 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 4 model years this bulletin names have filed 784 complaints with NHTSA since 2015. 427 of them name Power Train, 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 2023 Ford Bronco Sport, the 12 owners who gave an odometer reading for Electrical System reported it at a median of 25,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2023 Ford Bronco Sport. The contact was informed by his wife that when the start button was depressed, there was a loud boom coming from the vehicle. There was an odor of smoke coming into the cabin of the vehicle, but there was no smoke present. There was also a sizzling sound coming from the vehicle.

I started the Car and it made loud boom boom sounds like as if I was at a loud concert for about 10 seconds. That stopped but then loud static or electrical sound continued even after car was turned off. Re started and the sound continued. The initial sound shook me and wife.

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 25-2127 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 25-2127 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 25-2127 cover?
The manufacturer filed it against 4 model years: 2024 Ford Bronco Sport, 2023 Ford Bronco Sport, 2024 Ford Maverick, 2023 Ford Maverick. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
