Are you talking about the weep hole that most water pumps have?
If so that is not bad design, it actually works as intended, it helps keep the coolant from getting to the bearings in the center of the pump, it is supposed to help it last a little longer before totally failing.
Of course I am not familiar with the Cruz'*, I have had experience with water pump weep holes leaking though, and if they did not leak when the coolant gets to them, then the coolant would get to the bearings and totally ruin the pump a lot faster.
