Wow! I'm so glad I found this thread!
I thought it was my imagination at first when I noticed that.
The air blowing in through the vent felt noticeably warmer than the air I'd get with the window open . . . I mean like 10 degrees warmer. I did try fiddling with the dial, and a couple times switching it all the way into the "max" setting (which turns on the AC with only interior circulation) which seemed to help.
But then one day, I happened to have the AC on and noticed it wasn't very effective. I held the back of my hand up to the console vent on the driver's side, and I could feel warm air on the lower edge of the flow, while the upper edge and the left-side vent were blowing cool. I was driving, so I couldn't test out each one, but I tried turning the max down a notch to regular, turning it from driver to windshield and back, whatever. Bottom line was that I could not get unheated outside air.
So, I suppose I should add this to the various things I need the dealer to look into.
