What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 704 complaints with NHTSA since 2015. 426 of them name Electrical System, Power Train — 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 Mustang Mach-E, the 17 owners who gave an odometer reading for Electrical System reported it at a median of 30,696 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2023 Ford Mustang Mach-E. The contact stated while driving approximately 35 MPH, a MIL warning illuminated, with the message “Immediate Loss of Power” displayed. The contact stated that the vehicle shut off and the battery was drained. The contact stated that the vehicle stopped and independently shifted to park(P).

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51705 a recall?
No. A service bulletin 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 SSM 51705 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 SSM 51705 cover?
The manufacturer filed it against 5 model years: 2023 Ford Mustang Mach-E, 2022 Ford Mustang Mach-E, 2021 Ford Mustang Mach-E, 2023 Ford Transit, 2022 Ford Transit. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
