I went to turn mine another 90 deg turn (total 270 deg counterclockwise) because I noticed more creaking and discovered the bump stops had basically tightened back up (rotated almost 180 deg clockwise), either from driving or opening / shutting the hatch which happens often in my car.
Everyone, have you checked your bump stop adjustments after a week, etc. to see if they are holding their position?
KIA, I think you are going to have to address this issue with tighter tolerance bump stops at the very least...
