ditto; same thing recommended. should stop most airflow when in recirculate and the system is off.Do you have the re-circulate button turned on? If its off, the outside vent is still open, even in the off-mode. Mine does it.
Look for this button and make sure the LED is lit on it:
That should stop the air from coming through.
I've had that issue a few times too. It seems to happen if I have it in Auto w/ it off, and then hit the off button. Its like it still thinks its on. So I have to turn it on, set it to A/C and Recirculate, and then turn it off again.My issue on my K900 is that the little re-circulation button is turning off on it's own randomly and then outside air is coming in.

I definitely think its a bug in their software. Might report it and see what they say.
I'll have to take a video of it the next time it does it.
My issue seems to be a lot larger, I may have to contact an attorney about it since Kia cannot seem to fix the issue. Well that and another problem I am experiencing.Pressing the Auto button will turn off the re-circulation (RC), if active. Seems the default mode is RC off. But changing the temp setting (without touching auto) will leave the RC mode on.
This is same for my Hyundai; so may be the way its set up for all Hyundai/Kia. BTW, on the Buick I could not use RC in auto mode. Pressing RC forced AC to manual setting, not sure why they do that.
I believe that is because the front defroster relies on outside air to quickly regulate the windshield and clear the fogging faster.I notice that when the front defroster option auto turns on (when fog is on the window) my RC button turns off. :-/
That is because when your sunroof is open, it creates a vacuum in your car drawing air into the vents, and then it has nowhere to go, so it comes back out.I noted that with the AC off and the Sunroof open, the vents blow. Close the roof, vents stop blowing.
That, and all vehicles, like a home are required to maintain a certain percentage of clean air flowing into a space. If your car prevented any air flow at all, you would be breathing whatever fumes seeped into your car.lots of interest in this topic! and lots of ideas and suggestions; a friend who works for KIA basically told me the KIA climate control design is not nearly as sophisticated as other makes and has lots of quirks.
if any air blowing through the vents is a big issue, you always have the vent wheels which can be turned to off and close the vents for sure. that's the wheel beneath each vent; turn it to the left to close the vent; should resolve that issue.
