Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 9 complaints with NHTSA since 2015. 4 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.
The contact owns a 2025 Ford F-150. The contact stated that while driving at an undisclosed speed, the message "High Voltage Battery Fault" was displayed and then the message "Take Vehicle to Dealer" was displayed. The vehicle was taken to the dealer, but no cause of failure was found.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 25B64 a recall?
No. A manufacturer communication 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 25B64 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 25B64 cover?
The manufacturer filed it against 1 model year: 2025 Ford F-150 Lightning. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
