My wife was driving home. She had taken the highway home when she had suddenly lost power with no warning or indication from the cars dashboard there was no warning lamps or messages explaining why the car lost power and that the car would not turn back on. The vehicle was towed to an independent mechanic where it was determined that the engine was seized up and that the motor needed to be replaced and that the car had no oil in the engine. Which is not possible since the cars Maintenace intervals were maintained. It was also later determined that the oil pan bolt was under tighten due to bad threading on the oil pan and bad oil pan seals. The car will be towed to a dealership for further inspection. This issue presents a possible fire hazard or risk of accident while at high speeds. My wife did suffer a small injury to her forehead after rapid loss of speed from the steering wheel.
