Service bulletin SB-26-18-002

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.

NHTSA's summary

On some Model Y vehicles built before February 28, 2026, the design of the HVAC inlet duct may lead to water ingress into the air filter and/or vehicle interior. If the vehicle is brought into Service for cabin air filter replacement due to a musty or moldy smell from the HVAC system, water dripping from the vents or water pooling into the RH footwell carpet, inspect the vehicle for symptoms related to the condition. If symptoms are present, replace the HVAC inlet duct with an updated part or rework the existing HVAC duct, and replace the cabin air filters.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
