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.

What owners reported
Source: NHTSA complaint databaseOwners of the 10 model years this bulletin names have filed 251 complaints with NHTSA since 2015. 55 of them name Electrical System, Visibility/Wiper — 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.
Truck lost all electrical power while backing a trailer up. Engine died, no steering, no brakes, no power on dash, no emergence brakes, no power to door locks, no power to windows. If vehicle had been moving any faster no telling what could have been. Vehicle was towed to ford dealership and zero reasons for such a total loss of power.

The trailer light control module is intermittently causing trailer light faults messages and signal failures. This is associated to recall 26C10. The software update doesn’t correct the problem. Ford does not have the hardware on hand to replace the failing part. This is a safety issue for us who are on the road towing travel trailers

The navigation is intermittent, which causes the dash and connectivity to stop, which makes the dash go blank. Come back on and has shut the truck off a couple of times. Ford is saying it's connectivity, they're connectivity. People is saying the software software people are saying it's hardware. The dealer refuses to work on it.

Source: NHTSA, 49 CFR 579.5Is Ford PDM-26.21.5 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 PDM-26.21.5 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 PDM-26.21.5 cover?
The manufacturer filed it against 12 model years: 2026 Ford Expedition, 2025 Ford Expedition, 2026 Ford F-150, 2025 Ford F-150, 2026 Ford F-250 Super Duty, 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.
