What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 1,361 complaints with NHTSA since 2015. 360 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 Bronco Sport, the 67 owners who gave an odometer reading for Electrical System reported it at a median of 41,426 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 Bronco Sport. The contact was informed by his wife that when the start button was depressed, there was a loud boom coming from the vehicle. There was an odor of smoke coming into the cabin of the vehicle, but there was no smoke present. There was also a sizzling sound coming from the vehicle.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 55149 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 55149 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 55149 cover?
The manufacturer filed it against 4 model years: 2024 Ford Bronco Sport, 2023 Ford Bronco Sport, 2022 Ford Bronco Sport, 2021 Ford Bronco Sport. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
