The smell can develop without ever using overheat protection with A/C, including in areas that don't have particularly high humidity like the South Bay Area. I've never had that option on, but my car still developed the smell about 8 months in. But this new "dry cycle" feature that they implemented in one of the recent firmware updates may (hopefully) help to prevent or slow it down in the future. But if your car is already affected, the evaporator must be cleaned (and perhaps the filters replaced).
Not familar with the dry cycle and didn't see anything in the current manual or in any release notes that I received. More info?
