Anyway there are a couple of threads on smells. If it is a hydro carbon smell that is not present if the ventilation system is on recirculation or when the car is moving it most likely is coming from the transmission fluid and will eventually fade. If it is a moldy smell that is present in all ventilation system settings you need to have your HVAC system disinfected by the dealer.
With the hood open, you should notice clear circular stickers covering holes. That's a sign that the minor recall was applied to your car. Somehow and I don't know the particulars it prevents the cabin smell. My 2018 had this already done on delivery, i still had the scent at small levels for about 2,500 miles. It's no longer there.
Moral to the story.... Ensure you have clear stickers and keep on driving!
