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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford ECG-26.2.11.4 a recall?
No. A over-the-air update 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 ECG-26.2.11.4 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does ECG-26.2.11.4 cover?
The manufacturer filed it against 9 model years: 2026 Ford Expedition, 2025 Ford Expedition, 2024 Ford Expedition, 2023 Ford Expedition, 2022 Ford Expedition, 2022 Ford F-150 Lightning and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
