A manufacturer communication 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 14 model years this bulletin names have filed 2,641 complaints with NHTSA since 2015. 558 of them name Electrical System, 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 2020 Ford Explorer, the 61 owners who gave an odometer reading for Electrical System reported it at a median of 12,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Vehicle wouldn't start using push button start, several modules/components reported errors: traction control, parking break, steering, shifting. The vehicle drove fine less than 24 hours prior to 3/3/2024. Following a week at the dealership, Ford Motor Company and the Ford dealership determined the main wiring harness was the culprit.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford 23B64 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 23B64 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 23B64 cover?
The manufacturer filed it against 14 model years across 2 brands (Ford and Lincoln): 2023 Ford E-Transit, 2022 Ford E-Transit, 2024 Ford Escape, 2023 Ford Escape, 2023 Ford Explorer, 2022 Ford Explorer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
