Yesterday i had to pull her over..she overheated very badly ... all of a sudden. I put her in the shop asap...it was soo hot i couldnt even drive her. No smoke, no leaks, no steam...just a (engine coolant very hot) message on the display. I dony know if i lost coolant or blew a head gasket but she overheated horribly. I just purchased this car and i do not know if coolant or thermostat has ever been changed (128,000) miles.
