Ford bulletin TSB 26-2432
What it saysReason for update: To update the Service Procedure to include diagnostics for the fuel vapor vent valve and the fuel tank isolation valve. NHTSA’s full summary ↓
Ford filed this with NHTSA as a service bulletin dated Oct 16, 2026, received Oct 21, 2026, about the fuel/propulsion system. It names 6 model years (2021–2026). 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 bulletin supersedes 26-2238. Reason for update: To update the Service Procedure to include diagnostics for the fuel vapor vent valve and the fuel tank isolation valve. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P2450 stored in the powertrain control module (PCM). This may be due to a concern with the fuel vapor vent valve and/or the fuel tank isolation valve.

Read by machine from the document NHTSA serves (3 pages), read Oct 23, 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 6 model years this bulletin names have filed 3,000 complaints with NHTSA since 2015. 672 of them name Electrical System, Fuel/Propulsion 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 2022 Ford F-150, the 33 owners who gave an odometer reading for Fuel/Propulsion System reported it at a median of 33,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

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 26-2432 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 26-2432 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 26-2432 cover?
The manufacturer filed it against 6 model years: 2026 Ford F-150, 2025 Ford F-150, 2024 Ford F-150, 2023 Ford F-150, 2022 Ford F-150, 2021 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
