While I was driving in the fast lane on the highway my 2010 Ford Fusion sport overheated and cut off due to a faulty heat pump which resulted in coolant leaking into it and warping my engine. There was no check engine light or any other indicator that there was an issue with my vehicle. I had even just gotten my car "winter ready" with my mechanic and in November.
