It's likely leaking from the plastic grommet that mates the pump to the reservoir. It's a common problem. It's a $3.00 part. Part number 98622-14200.

In addition to leaking at the grommet they also leak at the the distribution T that's mounted to the pump.

Just one of Kia's "better ideas". It's a very common problem throughout the Kia/Hyundai product line regardless of model. As a matter of fact if you look at the pump carefully it even stamped "Kia/Hyundai". My daughter's Optima has the same issue. With the Sorento you can just undo some of the undercarriage cover and move it out of the way. I haven't tackled the Optima yet but it looks as though you need to remove the front bumper cover.
