What it saysThis article supersedes TSB 25-2119 to update the vehicles affected, parts list, and Service Procedure. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Nov 6, 2025, received Nov 13, 2025, about the power train. It names 8 model years (2021–2022). 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.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationThis article supersedes TSB 25-2119 to update the vehicles affected, parts list, and Service Procedure. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0420 and/or P0430 stored in the powertrain control module (PCM). This may be due to the software in the PCM. This condition does not affect vehicle drivability or durability.
Trouble codes it names: P0420 P0430

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.

Then while I was driving and turning around in a parking lot it actually stopped, everything went dead, no lights, key didn't have any affect, nothing, and then it started after 10-15…

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TSB 25-2549 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 25-2549 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 25-2549 cover?
The manufacturer filed it against 8 model years: 2022 Ford F-250 Super Duty, 2021 Ford F-250 Super Duty, 2022 Ford F-350 Super Duty, 2021 Ford F-350 Super Duty, 2022 Ford F-450 Super Duty, 2021 Ford F-450 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
