I was going from one section of the parking lot to another section. I was slowly making a right turn into that area as there were a lot of empty parking spaces. As I turned, suddenly I felt that I could not control the car. I tried to steer and tried to stop the car. I was alarmed, thinking why the car won’t stop. Then my car slammed into a parked car, and spun it around. My car finally came to a complete stop. I don't know if the same problem has been reproduced. The vehicle is now at a collision repair shop. There was not warning lamps, messages or other symptoms of the problem prior to the failure.
