Official summary
Some vehicles may exhibit the rear parking sensor beeping without any obstacles behind it when the shift lever is shifted into Reverse. This concern only occurs when the rear USB power outlet (1) is broken. This is caused by noise from USB interference with the harness of the rear parking sensor (when the USB power outlet is broken).To correct this issue, the configuration of the USB power outlet has been changed to improve durability.

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.
