2019 Cadillac XTS - Smokes

I have a 2019 cadillac xt4 and all of a sudden anytime Im driving when its raining or snowing, my car starts smoking once I turn it off. It also happens when I go through an auto car wash, the car will start smoking coming from the grill.

Probably not smoke. What you are seeing is water vapor. There is moisture on the radiator, if the electric fan is off the moisture will rise from the heat of the coolant in the radiator.
You will only see this on rare occasions when the vehicle is not moving and the radiator fan is off.
