This incident occurred at night time. About 10 min from a cold start, I turned onto the 210 fwy. There was a 270 degree downhill turn (a steep curve) so I had the brakes on while doing 15 mph. Half way into the turn, I suddenly lost brake and steering wheel froze. With some effort, I managed to turn the steering and stop the car. The engine died without warning. Later I sent the car to dealership but they could not reproduce the event.
