On some vehicles, the front door glass run channel may interfere with the rear door garnish. Since the front door glass run channel is not fixed strongly enough to the door, repetition of door operation may result in interference and damage to the rear door rubber seal.

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.
