Radio/tape Cd Player problems of the 2015 Chrysler 300

My 2015 Chrysler 300s has a dial gear shift that will not go into gear. I reside in nd and thought it was the frigid weather. The cars dial shift was stuck and ii had my two children with me in the cold -40 temp and -30 windchill. I had to walk to get help and leave my kids in vehicle. After being stuck for 4 hrs, I tried it again and the shift went into gear. It never happened again until oct 20th at 10:38 am. The weather was nice but the shift once again left my kids and I stranded after parking at a thrift store. After several tries and 1 hr the gear worked again. I'm a widow with 2 under age kids and need a reliable vehicle and this is not it. The radio changes stations when it wants, and the heated seats and heat work when used. The heat on the driver's side works when it feels but the air does blow. There is just no heat!! for north dakota that's not good !! my car is christine or you built a dangerous unsafe car !! now, I have to pay to have it fixed and the dial shift will cost me $400, the seats $300, and the electric problems are starting at $500 per bismarck repair shops, including Chrysler!! I am taking my car to eide Chrysler October 27th at 9 am and will have to pay labor costs with whatever extra they charge because this vehicle was built ppor and unsafe!! the vehicle was parked and off both times. When getting in to start it , the shift would not work. The first time was very cold, the second was a nice day. There's no rhyme or reason for these experiences.
