Official summary
Some 2021-2022 Bronco vehicles equipped with base exterior mirrors (does not have integrated puddle lamps and/or turn signal lamps) may have a whistle noise that originates from the left exterior mirror. This may be due to the design of the exterior mirror cover. To correct this condition, follow the Service Procedure to replace both the left and right exterior mirror covers.

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.
