What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 1,382 complaints with NHTSA since 2015. 755 of them name 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 2019 Ford Edge, the 106 owners who gave an odometer reading for Power Train reported it at a median of 70,911 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 2021 Ford Edge. The contact stated while stopped at a car wash, the vehicle independently shifted out of neutral into reverse, without warning. The contact depressed the brake pedal and the vehicle stopped. The vehicle was taken to the dealer to be diagnosed; however, no cause for the failure was found.

Transmission was shuddering when it shifted gears. It would lose power and jerk between each gear. We paid for diagnostic at the dealership and they diagnosed as torque converter shudder under 2 separate TSB's. Dealership offered to fix at a cost of $6400. Told not to drive the vehicle or at least as little as possible.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52064 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 52064 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 52064 cover?
The manufacturer filed it against 6 model years across 2 brands (Ford and Lincoln): 2021 Ford Edge, 2020 Ford Edge, 2019 Ford Edge, 2021 Lincoln Nautilus, 2020 Lincoln Nautilus, 2019 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
