Air Conditioner problems of the 2008 Subaru Impreza

I started to get a film on the windshield of my 2008 Subaru. I took it into the dealership and they did a test and found a problem with the a/c unit; they told me the film on the windshield was safe and car was safe to drive. I took the car in again while they were waiting for parts, for another issue, and I requested a copy of the tech notes and the film that was on the windshield was freon!- health hazard. They fixed this problem with the freon film, and now not a month later its back, and worse. I again took it into the dealer and he told me this is natural, that the gas in the upholstery needed to get out and that the gas is again safe. I asked the salesmen that I got the car from,he never heard of this. Still not fixed as this is a natural issue,there is also a foul odor coming out of the ac/heater system. I have also had issues with the traction control when activated the vehicle loses power in all of vehicle, has a loud noise coming form the right side of the car when the system is engaged; nav system when its turned on will go to blank white screen,will also not respond sometimes; need seat belt system replaced on the passenger side, was retracting when not needed; issues starting- hard crank over, sometimes had to repeat to start,or turn key over for long period of time. I am now having health issues as I drive the car everyday for hours. I have almost been in many accidents due to this issue. Wiping off don't help.
