My defrosters blow excessively when I have the dial set for floor heat.So much so I can't tolerate it and have to turn the temp and fan speed down,even though I need more floor heat.It is less than full defrost setting but way more than it should be.Anyone else have this problem?

Reading owners manual, at least in 2012 model, this is normal operation. I thought something was wrong too, since my KJ didn't do this and my wife's KK did. But dealer confirmed this along with the owners manual.
