NHTSA complaint #10525284, filed 2013-07, 38,000 miles

“I have had to change the radiator three times and getting ready to do it again the second time the truck ran hot and ruined the motor. I then put another motor and new radiator and it has not been 40000 miles and with no warning at all it done it again with all of the complaints that has been posted online this should have been addressed to every one that has this problem.”

“Thermostat/radiator failed causing entire engine failure. There has been several other complaints like this about the Explorer. My children and I were in the vehicle when it malfunctioned without any warning a big cloud of smoke and the vehicle shut off in the middle of heavy traffic this could have caused a very serious accident. This issue with the radiator needs to be addressed.”

“Radiator started leaking for no reason in 2006 Ford Explorer have been told by repair shop and other owners that this is a common thing the repair shop said that because this is a design flaw to expect it to happen again in a year I do not have 600. Dollars to put out every year on a vehicle that is not paid for should I let it go back.”

NHTSA complaint #10305358, filed 2010-02, 67,875 miles

“While driving the vehicle, the smell of antifreeze started coming into the car. My fiance' checked the radiator and overflow bottle and found out it was gas mixed with the antifreeze. My car's mileage is 80100. I do not believe the car should have this issue at only 5 years. This problem/complaint should be investigated and damages should be covered by the dealership or manufacturer.”
