What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 503 complaints with NHTSA since 2015. 121 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 2023 Ford F-150, the 13 owners who gave an odometer reading for Electrical System reported it at a median of 10,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
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 TSB 24-2116 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 TSB 24-2116 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 TSB 24-2116 cover?
The manufacturer filed it against 1 model year: 2023 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
