    These cars are notorious for blowing head gaskets. Exhaust gas pressurizes the cooling system and the coolant cannot circulate. Mine blew at 200,000 miles. Also, the fan clutch and the electric fan are prone to failure. These cars are good cars but once they hit the 150,000 mile post they have a lot or issues.
