Official summary
Some customers may complain that the front passenger seat belt warning light flashes and the seat belt warning beep is activated, even though there is no occupant in the front passenger seat. When a passenger seat occupant sits with a load on the front side for a long time with the seat warmer on, the occupancy sensor becomes dented and sensitive. As a result, the sensor determines that there is an occupant in the front passenger seat even though the seat is empty.

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.
