I recently brought a 2009 kia rondo but we find that we have to have the heat on high if the weather is at or below freezing. When driving there is cold air coming in through the door handles and the buttons on the doors, also the doors are cold to the touch. We have to wear our coats and gloves when driving. Has anyone else had this problem. Also the temperature gages are in US degrees, which we don`t understand any more.
