Same here. Can't see the point of the same stale air going around and around getting conditioned over and over. There must be some point to it and i'd love for someone to explain it but i'm with you in that the normal setting works perfectly.My Mii was set to air re-circulation when I collected it. Did not notice it for a few days until the condensation was driving me nuts. Not sure why the dealer set it, possibly knocked against when having a pre-delivery clean. It is a setting I have never used in all my years of driving.
