What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 153 complaints with NHTSA since 2015. 39 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.
This vehicle had an open safety recall at the time the dealership sold it to me. The recall existed before the sale and the dealership knew or should have known about it. The dealer submitted loan paperwork and accepted funding but never delivered the vehicle to me. I was not informed of the open recall before signing.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 54992 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 54992 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 54992 cover?
The manufacturer filed it against 3 model years: 2026 Ford Bronco, 2025 Ford Bronco, 2024 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
