Official summary
While driving on gravel or dusty roads, dust accumulates at the lower inner edge of the door garnish. When the rear door is opened, the dust may be blown up and enter the cabin, adhering to the seats and the floor. This is caused by a large gap at the lower part of the boundary between the rear door and the front door, and air containing dust and/or sand is sucked up into the gap, accumulating at the lower edge of the rear door garnish while driving. To eliminate this concern, a mass production change is under study.
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.
