What owners reported
Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 3,906 complaints with NHTSA since 2015. 770 of them name Electrical 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 2021 Ford F-150, the 32 owners who gave an odometer reading for Electrical System reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford TCU-26.2.11.3 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 TCU-26.2.11.3 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 TCU-26.2.11.3 cover?
The manufacturer filed it against 12 model years: 2024 Ford Bronco, 2023 Ford Bronco, 2022 Ford Bronco, 2021 Ford Bronco, 2024 Ford Expedition, 2023 Ford Expedition and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
