VEHICLE STALLED IN THE MIDDLE OF THE ROAD. AFTER NUMEROUS HOURS OF INVESTIGATIONS AND REPLACING POTENTIALLY FAULTY PARTS, IT WAS REALIZED THAT THIS WAS A WIRE HARNESS FAILURE. A COMMON PROBLEM FOUND ON THIS MODEL, I.E. DEGRADATION OF WIRING HARNESS, LEAVING BARE WIRES WHICH SHORT-CIRCUIT. THIS COULD POTENTIALLY CAUSE CATASTROPHIC FAILURE RESULTING IN DEATH IF NOT ADDRESSED SINCE THE HARNESS ESSENTIALLY CONTROLS ELECTRICAL AND SAFETY SENSOR. *JB
