Headlights problems of the 2013 Dodge Avenger

I recently reported my vehicle accelerating on its own up to the speed of 82 mph also thinking that this was a weird occurrence that would not happen again. I was wrong. While driving 40 mpg getting ready to enter a turn my car again started accelerating on its own, foot off the gas was not going down hill or any other reason to pick up speed. Also on this same day I started my car and my headlights came on as they should, I noticed my high beams on thinking they were left on from the last time I drove my car I turned them off. Driving down the road the high beams all of a sudden came in. I turned them off thinking it was strange. Again 2 more times on my way home the high beams automatically came on by themselves. I believe there are some major computer issues with this vehicle but again I am sure of chryslers response ahead of time. Called Chrysler they just say well if you take it to a dealer maybe they can see if there are any codes. Prior to this my sensor had gone bad, lights not working all kinds of things and the dealer was not able to find out what was wrong because there were no codes. Took to new dealer they used common sense and not waited for only codes to come up and found the sensor was dead. This vehicle is an accident waiting to happen!.
