Official summary
If you encounter a customer complaint of a white residue build up on the rear door partition glass or interior molding, it may be crystallized salt. Normally, the condition will occur during the winter months in states that use salt or similar mineral based anti-icing agents on their streets and highways. Under certain conditions, exterior water that enters the molding, and would normally drain away, may be drawn up into the interior of the partition glass molding where it will evaporate and leave trace mineral deposits behind. An additional seal rib was added to the inside lip of the molding

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.
