was driving and steam came pouring out of the engine.took it to kia in buford ga.not sure of the part but it had to do with the cooling system to over heat.then after paying 650.00 got the car home and two or three days later it over heated again the dealership said it was a defected part so they said it would have to stay over a day .my husband had to walk home because the dealership never offered a rental car free of charge because the part was defected.Why should we have to pay for a rental car because the dealership had a defected part( two defective parts)
