What owners wrote
I was driving and a part in my A/C began clicking loudly, then the air shut off completely and started smoking. A loud noise came from where the A/C blower motor is and within moments the entire car was engulfed in flames.
While driving on the highway the "service traction control" message comes on, then, the messages "service stability trak" then "engine power is reduced". And then the car shuts down I had to quickly pull over on the side of the road. After a few minutes the car starts up and everything is fine. This happened twice since then. Every couple months the sensor lights would come on with the above message-without car shutting down.
