EPC Light on a brand new car and no accountability!

A brand new car had epc light on a few months after delivery. Been given a run around for almost 2 years until eventually they straight up refused to fix it saying there's a broken wire and not covered by warranty. Every time i took the car in they would return it saying the light is gone. Of course the light would go on and off. If you want peace, stay away from this dealership!!!!!!!!!!!
