Seat Belt Related Problems of the 2014 Infiniti Q50

Seat Belt problem

The seatbelt on the driver side will tighten up across neck and chest when driver assist controls go off at will when car is coming to a stop or when car is being driven on uneven or bumpy roads. The seatbelt chokes me as though I am in an accident. I have pictures of the injury on my chest. In July, after the seatbelt did this, I started having problems on the left side of my neck. It was very painful, I had two pain injections done and neither worked. I have lupus which affects my joints and when I was sent to have a second opinion, the first thing the doctor asked was, had I been in an accident. I mentioned the seatbelt and he said it is a possibility that it inflamed the area. I had to have surgery on October 14, 2014. The car display system freezes. I have taken this car back to the dealer approximately 5 times with the most times being when it had less than 1000 miles. I have contacted Infiniti and they have set up 2 cases, with no effective results. I have never turned the heater on because the car gets very hot inside and I can feel the heat on my feet on the driver's side. I am anemic (very cold natured) in the summer 82 degrees is comfortable for me. This car gets very hot. I can feel the heat on the outside and sometimes I smell something burning when I get out. The display panel gives erroneous information such as "other maintenance?" and "tire maintenance?" but when checked, everything is fine. I have tired to work something out but they are refusing to accommodate me. Whether they refund my down payment and enough where I could trade out of this car. This is a leased vehicle (36) months. Money for pain and suffering. Because of this surgery, I will not be able to return to work until December and I am off without pay and this will be additional time without pay. I have filed a complaint with bbb. Please help me.
