I was exiting the highway into a rest area, and at about 30-35mph the car's engine suddenly cut out. All the dashboard warning lights lit up, the power steering failed, and even with the brake to the floor the car would barely slow down. I put the car in park and restarted it and it drove normally. I'm now afraid to drive my brand new car, because if the engine cuts out in the middle of an intersection or turning left against traffic, I could be involved in a very serious crash. This is more than just an inconvenience, it is a very serious safety flaw! if I was making a left turn against traffic and my two year old niece was in her car seat in back, she would be directly impacted by the vehicle due to the fact that the car decided to stop working!.
