While driving, a loud static sound started over the speakers and would not stop. It was so loud I could not continue driving and I immediately developed a headache. Even after I pulled over, turned off the truck and left for about minute it still continued.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52280 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 52280 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 52280 cover?
The manufacturer filed it against 10 model years: 2023 Ford E-Transit, 2022 Ford E-Transit, 2024 Ford F-150, 2023 Ford F-150 Lightning, 2022 Ford F-150 Lightning, 2024 Ford Mustang Mach-E and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
