What broke? Cross over bar?
Factory mounted rack rails are held on by machine screws that go through the roof and into threaded nuts.
If you get a Yakima, see if the cross bars will fit the Kia rails. If so, they might be a better choice, otherwise, if you replace the entire system, unless it is the same width, attachment will be by sheetmetal screws and you will have to plug the stock holes.
Just some food for thought...
