# 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.

TSB: Some 2022 model year NX 250 and NX 350 vehicles may exhibit water entry to the vehicle from the HVAC drain hose being disconnected from the air conditioning radiator assembly and/or a grease/oil odor emitting from the vents. These conditions may be caused by paraffin wax leaking from the evaporator and causing the drain hose to expand and/or emitting an odor
