“This problem started over a year ago and I have had it to the dealer twice and they can no find the problem because there are no codes in the car. While driving the car it shuts down and you lose everthing lights, turn singles, hazards,the dash goes totaly out and the engine stops the best you can do it to pull it over to the side of the road and hope you don't get hit. I have had this happen it town driving and on the highway so it has nothing to do with speed. I have loaned my car to other people and it has happened to them so it is not the driver. …”
