I was driving on the freeway at 65 mph. All of a sudden the car just stopped running. All dash board lights came on including check engine and theft light was blinking. Luckily traffic was light during the time I was driving. I ended up getting pushed off the freeway by the chp. I had to tow the car to the dealer, and the service advisor stated to me, that a wiring harness that was mounted above the cat converter, and the wire shorted out. Whatever was holding the wire in place must have came off, and that over time the wire shorted out because the wire harness was resting on the very hot surface of the cat converter. The dealer took pictures, and I could not believe that they put such a vital wire harness directly above something that gets extremely hot. I was lucky, but someone else my not be so lucky. No warning lights and a car just shuts completely down while driving. I hope you will look into this issue and not just the year and model of my car. This must be recalled before someone gets hurt or killed.
While driving smoke came out of the air vents. Then, rear seats caught on fire. This was caused by poorly designed speaker wires.
