This 2013 Hemi Dodge Durango has now had the radiator replaced twice due to leakage of coolant. The first time was under warranty at around 30,000 miles and then one year later at 50,000 miles (out of warranty), which cost me $1200 at the local Dodge dealership. These radiators are made from molded plastic and aluminum and the parts appear to be pressed together and definitely not welded. The leak comes from poorly made joints between the two different materials.
