My husband and I was driving in traffic from an appointment and all of a sudden the car starts smoking within a quick second the front left side burst into flames, electrical windows wouldn't work and the brakes failed, the we had to ride traffic until we could move over to the curve at this time the emergency brake had to be used in order to stop the car and I had to move myself out on the drivers side.
Intermittently when it is raining there is a total loss of electrical power and engine quits. Vehicle has been seen since by two dealerships. Neither dealership was able to determine what is causing this problem.
