Official summary
Some 2020-2024 Explorer/Aviator vehicles may exhibit poor speaker sound quality and/or tick-tock noise while activating turn signals and streaming audio over Bluetooth. Customers may describe static heard during a Bluetooth phone call or a door speaker buzz or tick noise with the pulse of the turn signal. This may be due to concerns with the 14401/14A005 wiring harnesses or connector damage. Prior to the replacement of the affected speaker, inspect for incorrect pin fit/crimp, bent pins, broken wire strands, or other damage at inline connectors C202, C2383A, and/or C4240B.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
