Likely due to no rust proofing causing corrosion to the underneath lines

You would think that a company like Kia would realize that were we live in N.A. we see a lot of snow and cold weather and that some times we might be left stranded in frigid weather and no fluid left in the vehicle so you could at least leave it run so you would freeze !!!!!!!!!!! These water hoses to the rear should be high pressure rubber with stainless steel or non corrosive fittings.
