Hi guys, i just leased a 2008 Atima Sedan 2.5s. I have about 1200 miles. Everytime i drive over 30-40 mph i get hot air coming inside the car through the air ducts..I went to dealer and they said its suppose to do that, just close the vents...but its annoying because i cant close the vents where my feet are...anyone have that problem??? Thanks

First off - welcome!

2nd - the car is supposed to leave the vents slightly open - it's a safety feature designed to allow air to breathe through the car so it doesn't explode (your car can "pop" if it gets too hot with no air movement - think balloon).

The easiest way to remedy this is to a) put the fan on to move air or b) put your system on the head setting, don't turn the fan on, and close the vents...
