Head-gaskets and/or thermostats failing under normal driving conditions and low miles. I am on 2nd head-gasket and 4th thermostat and only at 109000 mi. Twice this has happened while driving on freeway and twice while around town. Fluid levels were good and other maintenance done regularly. I have talked with multiple kia dealership service departments and they start by saying that is not normal then after looking over the car saying its a normal thing for Souls. These failures have caused the engine to overheat each time once the thermostat sticks closed. No engine warning lights and temp gauge only showed the overheat 2 out of four times. They seem to be failing fairly regularly around 20000 mi.
