- 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.
