I'm a little late to this party. I've done the 1 notch change for the wipe, but I also agree these auto wipers don't perform well in the snow, mine just don't wipe hardly ever.
Second to that, if you don't have the defrost up high enough or you don't wipe the window enough, snow becomes frozen to the blades and leaves crazy bad streaks. I've never had this problem on any other car. And why did Kia remove the heated wiper blade strip on the windshield, I had that on my '12
Sportage SX. It's already a million dollar replacement windshield, so that heated bit couldn't have made it cost too much more lol.
