What it saysCertain 2017-2019 Model Year Super Duty Vehicles w/ 6.7L Diesel Engines Diesel Particulate Filter Replacement, If Required After Dealer Evaluation NHTSA’s full summary ↓
Ford filed this with NHTSA as a manufacturer communication dated Aug 26, 2026, received Sep 1, 2026, about the engine. It names 9 model years (2017–2019). A manufacturer communication 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 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

NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.

There was no warning light illuminated. Due to the failure, the vehicle was towed to a dealer and was diagnosed with engine failure.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 26N03 a recall?
No. A manufacturer communication 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 26N03 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 26N03 cover?
The manufacturer filed it against 9 model years: 2019 Ford F-350 Super Duty, 2018 Ford F-350 Super Duty, 2017 Ford F-350 Super Duty, 2019 Ford F-450 Super Duty, 2018 Ford F-450 Super Duty, 2017 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.
