What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome vehicles equipped with power folding mirrors may exhibit power folding mirrors that are inoperative or exhibit a clicking sound. This may be due to the mirrors being manually folded in, during transportation, going through a car wash, bumped in a parking lot, or found during pre-delivery inspection (PDI). Prior to the replacement of any components, attempt to synchronize the mirrors by following the Power Mirrors Synchronization procedure. Refer to Workshop Manual (WSM) Section 501-09 Rear View Mirrors - General Procedures - Power Mirrors Synchronization.

One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

I turned on the truck and heard a loud crack followed by load static originating from the front passenger area. This was from the stereo speakers. My right ear endured a lasting and substantial amount of pain. I will estimate, based on measurements of SPL I've made as an engineer, that the crack was approximately 120dB
2022 Ford F-150 · Equipment · filed with NHTSA Oct 10, 2022
When I pressed Start yesterday a loud ear-splitting noise emitted from the sound system. It took my shocked brain a moment to realize it wasn't a security alert. When I realized nothing I did would get it to shut off, I got out of the vehicle. It eventually stopped, and the sound system doesn't work at all now.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 51937 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 51937 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 51937 cover?
The manufacturer filed it against 58 model years across 2 brands (Ford and Lincoln): 2023 Ford Expedition, 2022 Ford Expedition, 2021 Ford Expedition, 2020 Ford Expedition, 2019 Ford Expedition, 2018 Ford Expedition and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
