Ford bulletin TSB 26-2256

What it saysThis article supersedes TSB 25-2572 to update the Parts List to correct the part number LC3Z-6006-L to LC3Z-6781-A, remove the flex plate bolts AL3Z-6379-BA from the parts list as these bolts are in kit LC3Z-6781-A… NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Jun 19, 2026, received Jun 22, 2026, about the engine. It names 50 model years (2020–2025). 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 (10 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 database

Owners of the 23 model years this bulletin names have filed 1,340 complaints with NHTSA since 2015. 151 of them name Engine — 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 2020 Ford F-250 Super Duty, the 15 owners who gave an odometer reading for Engine reported it at a median of 64,000 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 2022 Ford F-450SD. The contact stated while driving 50-65 MPH, the vehicle lost drive power and the instrument panel lights started flickering. The check engine warning light was illuminated. The contact was able to pull over to the side of the road. The vehicle was able to restart, and the contact resumed driving.

2022 Ford F-450 Super Duty · Engine · filed with NHTSA Feb 6, 2025 · ODI 11641049

The contact owned a 2024 Ford F-450 SD. The contact stated that while his fiancée was driving with cruise control set to 57 MPH, there was an abnormally strong smoky odor inside the cabin of the vehicle. No warning light was illuminated. The driver pulled over to the side of the road and there were flames coming from the engine bay.

2024 Ford F-450 Super Duty · Engine · filed with NHTSA Aug 18, 2026 · ODI 11757734

The contact owns a 2020 Ford F-450. The contact stated while driving 70 MPH, the vehicle vibrated and the vehicle briefly lost motive power. The vehicle returned to normal functionality once the accelerator pedal was depressed. The vehicle was taken to the dealer, who diagnosed a failure with the power train control module (PCM).

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 579.5

Is Ford TSB 26-2256 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 26-2256 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 26-2256 cover?

The manufacturer filed it against 50 model years: 2025 Ford E-Series, 2024 Ford E-Series, 2023 Ford E-Series, 2022 Ford E-Series, 2021 Ford E-Series, 2025 Ford F-250 Super Duty and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
