What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 2,586 complaints with NHTSA since 2015. 489 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.
On the 2021 Ford F-150, the 32 owners who gave an odometer reading for Electrical System reported it at a median of 30,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52078 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 52078 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 52078 cover?
The manufacturer filed it against 3 model years: 2023 Ford F-150, 2022 Ford F-150, 2021 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
