Official summary

Some vehicles in particular geographic areas may exhibit a condition where the HVAC Evaporator Drain Hose has become obstructed with an insect nest. An insect repellent drain hose tip (ARINIX® Tip) is now available to help minimize future occurrences of this environmental condition. For some models, a new drain hose is required to properly fit the ARINIX® Tip. Follow the procedures in this bulletin for proper handling and installation of this optional service part.

Vehicles covered

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.
