The car has stopped with no warning no lights came on and nothing happened to cause this. I was driving on the expressway going 55 mph and it came to a sudden and complete stop as I said no warning lights came on. I took the car to the dealership and they investigated and said that they could not find the nature of the problem. This is bull! it has happened on two other occasions and it is dangerous.
