Ford filed this with NHTSA as a service bulletin dated Oct 27, 2025, received Oct 28, 2025, about the power train. It names 18 model years (2023–2026).

Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationWhat it applies to, as the document itself states it — the build window in the manufacturer’s own words, read by machine from the PDF NHTSA serves. The build date is on the certification label in the driver’s door jamb; the dealer settles a borderline vehicle by its VIN.
Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated MIL with DTC P0384 stored in the powertrain control module (PCM). This may be due to the calibration in the PCM. This condition does not affect vehicle drivability or durability.
Trouble codes it names: P0384

Read by machine from the document NHTSA serves (1 page), 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 9 model years this bulletin names have filed 217 complaints with NHTSA since 2015. 93 of them name Electrical System, Power Train — 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 owns a 2024 Ford F-350. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted. There was no warning light illuminated. The vehicle was taken to the dealer but was not diagnosed or repaired. The dealer informed the contact that a software update had been completed on the TCM.

Less than 4000 miles- first transmission failed while pulling a large trailer- ford replaced the transmission and the new transmission, only 200 miles later did the same thing when pulling a trailer, up hill. It throws the transmission into 10th gear and you loose all power, Check engine light comes on and it slams back into 4th gear.

Multiple electrical issues related to dashboard controls, video sensors, head unit. Controls powering down while driving, sensors throwing multiple error messages. All since 1,500 miles. Ford could not figure out what the issue was so they replaced the wiring harness. After 2 months in the shop I got my vehicle back.

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 25-2515 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 25-2515 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 25-2515 cover?
The manufacturer filed it against 18 model years: 2025 Ford F-250 Super Duty, 2024 Ford F-250 Super Duty, 2023 Ford F-250 Super Duty, 2025 Ford F-350 Super Duty, 2024 Ford F-350 Super Duty, 2023 Ford F-350 Super Duty and more. 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: 2024-2026 F-650/F-750: built on or before 25 Sep 2025 — the build date is on the certification label in the driver’s door jamb.
