I have driven 3 rx8 in my time.

I have experienced the fogging wind screen on my own car and one other test car. But it was not present in 1st car I tested.

I am guessing here but I suspect that the cars have humidity from the factory which gets sealed in the car before they are transported.

When the cars are transported to a cold climate the humidity starts to cause the front wind shield to steam up. You get the same effect in an older car with poor door seals. When you remove the moisture from the car the effect disapears.

After a weeks driving I noted that there was sufficient quantity of water on the rear window to bead. I removed this water with a cloth and after that the car stopped steaming up.

I do also run the heating system with hot air to the wind screen and feet. Press the mode button on the heater controls and you will see the display change to various options.

Dont worry about this problem its short lived. I have to be honest at first I thought I was getting too excited driving the car!
