Consumer Description

When I turned my car on after work every warning light on the dashboard was on. A few of the warning messages read: Collision Mitigation Braking System Problem, Adaptive Cruise Control System Problem, Hill Start Assist Problem, Electric Power Steering System Problem. I first took it to Oreilly's to have the diagnostics ran. They told me the ignition coils needed to be replaces. We replaced the ignition coils and the spark plugs. The lights stayed off for about 3-4 days and then the same thing happened again. I took it to the dealership to be checked out and they told me that the head gasket had failed and coolant was leaking into the cylinder and causing the engine to overheat.
