One problem related to radiator has been reported for the 2013 Toyota Prius. The most recently reported issues are listed below.
Drove over object. Pulled over right away. Object dislodged. Didnt see any fluid kept on driving. After 15 miles engine overheating light came on and pulled over immeditiately and turned off engine. Had car towed to nearest Toyota dealer. Now I m told that object tore a hole in radiator which caused all the fluid to leak out and caused engine to overheat. To the point of no longer working. What is the point of having a warning light that comes on when its too late to remedy the situation?.
