Yeah, my Model 3 got that after the first few months of having it. They flushed the system and replaced the filter (which miffed me a bit because it’s a known issue and yet they still charged me for it). Never came back in my case through, so I wonder why yours is returning?We're not having a moldy smell in our Air, but we're getting a very strong moldy odor in our Tesla Model S. The Tesla system was cleaned on its last service visit and the filter replaced, but the smell returned within a couple of weeks. We don't know what to try next.
Just about everyone I know who owns a Tesla has been through this. But it’s usually a one-time fix.
