My son's Sonata has a problem where every time he drives in the rain and goes through a puddle he will momentarily lose power steering. I looked under the front of the car and there appears to be a splash shield of some sorts that is missing near the belt driven power steering pump that I believe that's causing the problem. I've did some image searches but I'm not sure what it looks like. Is there someplace where I can search for a part number for this item? Thanks and Merry Christmas to all!
