Official summary
Some customer's may complain that In heavy rain, the front parking sensor system detects objects despite nothing being in front of the vehicle, and no related DTCs are stored. This may be caused by the ultrasonics diffusing inside when the front parking sensors get wet. As a result, the parking assist unit mistakenly detects objects near the front of the vehicle. To correct this issue, the detecting logic in close range has been improved.

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.
