Official summary
Rear Park Distance Control Does Not Work. When the reverse gear is selected or the PDC button is pressed, the rear PDC sensors do not work and, at times, there is no check control messages displayed. CAUSE Water ingresses into the PDC sensor. This is because the wire connection for the driver's side rear outer PDC sensor is not protected from water, dirt and other foreign materials kicked up by the driver's side rear wheel.

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.
