Service bulletin L-SB-0031-23

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

These conditions may be caused by paraffin wax leaking from the evaporator and causing the drain hose to expand and/or emitting an odor
