Charging system malfunctioned, sensors melted in valve trane, radiator elbow and fill neck blew off, complete engine failure and battery failure. I have had a problem with the "check brake" light and an alarm going off. However, when I stopped driving and had it towed to the dealership they could find nothing. Prior to this incident, I took a photo of my dash, I had 76,499 miles and the coolant meter did not read hot.
