Official summary
Some vehicles may exhibit that the glass run channel of the front door interferes with the rear door garnish. Since the front door glass run channel is not fixed to the door strongly enough for the following situations, cycles of door operation may result in interference and lead to damage on the seal rubber at the rear door.

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.
