On 5/11 my wife was driving when she heard a clicking sound. She was not far from the dealership and decided to drive the car in to get looked at. As she got close to the dealership the vehicle started to smoke. She pulled over to a safe location where she could get out and as she was pulling over the vehicle started to flame. She immediately grabbed the dog and jumped out of the car and called 911. Withinjust a couple minutes of exiting the vehicle it was fully engulfed in flames and exploded.

Mileage was about 16,500. On the freeway going about 70 mph, car shut down with alarm information and into a controlled glide, not allowing acceleration. After almost being run into I was able to move to the right shoulder and per directions, shut off motor. Was able to restart. Went three miles to my destination and car was towed to dealer. They did not know the problem, and after two days I got the car returned. They said they had to call the manufacturer to find the defect. Going home that evening after traveling about eight miles and again on the freeway going about 70 mph, the car again did the same thing on the freeway. Again starting it, the car went another five miles on the freeway when it again happened. Three times, same thing!!! (much like what I read about the prius two days ago.) no longer feeling the car was safe in that it is difficult to Dodge vehicles on a freeway when a car shuts down three times, I traded it in. All I was told by the dealer that it had to do with the hybrid system.
