Mine and my wifes did that within 2 weeks of each other. I changed the thermostats and put 50/50 coolant in them and they run great now The thermostats were the main cause but EVERYTIME I tried to run straight coolant without diluting it it overheated I go half water half coolant haven't had a prob since
