What owners reported
Source: NHTSA complaint databaseOwners of the 3 model years this bulletin names have filed 847 complaints with NHTSA since 2015. 211 of them name Engine, 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.
Within the first 500 miles on my brand new bronco, I noticed a strange burning smell after driving it one day. The next morning when I started it, I heard what I thought was a heat shield rattle, and as I continued to drive my bronco to work throughout the week the noise got worse.

Was driving my son to school, maybe 30 mph when all of a sudden I heard some clicking noises from the engine. The power dropped and I was barely able to pull over to the side of the busy road out of harms way. Engine dead.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51961 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 51961 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 51961 cover?
The manufacturer filed it against 3 model years: 2023 Ford Bronco, 2022 Ford Bronco, 2021 Ford Bronco. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
