The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 6 model years this bulletin names have filed 841 complaints with NHTSA since 2015.
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 52008 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 52008 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 52008 cover?
The manufacturer filed it against 7 model years across 2 brands (Ford and Lincoln): 2023 Ford Bronco, 2023 Ford F-150, 2023 Ford F-250 Super Duty, 2023 Ford F-350 Super Duty, 2023 Ford F-450 Super Duty, 2023 Lincoln Corsair and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
