Ford bulletin TSB 26-2428

What it saysReason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve… NHTSA’s full summary ↓

Ford filed this with NHTSA as a service bulletin dated Sep 29, 2026, received Oct 2, 2026, about the electrical system — 2 documents under this number. It names 7 model years across Ford and Lincoln (2023–2025). 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.

One page for every brand it was filed under. Each brand’s bulletins: Ford · Lincoln.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication
2023-2025 Escape on or before 21 Apr 2025 “Built on or before 21-Apr-2025”
2025 Maverick on or before 28 Apr 2025 “Built on or before 28-Apr-2025”
2023-2025 Corsair on or before 21 Apr 2025 “Built on or before 21-Apr-2025”

What 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.

This bulletin supersedes 25-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. 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 the software in the PCM and/or the fuel tank isolation valve.

Trouble codes it names: P2450

Read by machine from the document NHTSA serves (2 pages), read Oct 4, 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 7 model years this bulletin names have filed 365 complaints with NHTSA since 2015. 191 of them name Electrical System, Power Train, 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 2023 Ford Escape, the 16 owners who gave an odometer reading for Electrical System reported it at a median of 15,500 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

If the vehicle sits for more than 36 hours, it enters a deep sleep mode and develops an unresolved battery drain issue, rendering it inoperable. This vehicle has been in the shop four times with three battery replacements having less than $30,000 MI if a person or to drive this out of town or park at a rest stop, it could lead them…

The contact owns a 2023 Lincoln Corsair. The contact received notification of NHTSA Campaign Number: 26V091000 (Electrical System); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.

The digits no longer display on the speedometer gauge of the electronic dashboard. Digits on the high voltage battery discharge and charging gauge also do not display. Given those failures, I have concerns about warning lights that may not be working. The lack of proper speed indication increases the possibility of a collision.

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 26-2428 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 26-2428 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 26-2428 cover?

The manufacturer filed it against 7 model years across 2 brands (Ford and Lincoln): 2025 Ford Escape, 2024 Ford Escape, 2023 Ford Escape, 2025 Ford Maverick, 2025 Lincoln Corsair, 2024 Lincoln Corsair 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: 2023-2025 Escape: built on or before 21 Apr 2025; 2025 Maverick: built on or before 28 Apr 2025; 2023-2025 Corsair: built on or before 21 Apr 2025 — the build date is on the certification label in the driver’s door jamb.
