Radio/tape Cd Player problems of the 2012 Dodge Grand Caravan

I have a 2012 Dodge Grand Caravan the sliding door has been making a buzzing sound every time you unlock and lock the doors. This has been happening since 2016 and the dealership told me it would be $500 to fix it. I am now having issues with trunk opening and closing on it's own; even when it is locked. Not safe at all and already got stormed inside of my van; cause I didn't realize it was opened. They told me I would have to pay the fee to get it looked at and then pay for the repairs. I had a new transmission put in at 74,330 miles after they told me when I left the first time; that it was a computer reset that needed done. Then, they had my van for 2 weeks trying to get the transmission built. And my transmission is slipping again. At 139,466 miles I had all of my transmissions lines leaking and had replace all of them for another $500; cause there was no warranty from them doing my second transmission. My cd player eats my cd's now and my ac quit working. All in all I do love my van, but I am getting very angry at all the issues; that should covered under a recall and they are not covered. If anyone could please give me some in site on these issues; I would appreciate it. I am not in the position to purchase another car at this time with jobs not very secure. I am not even able to take my van many places; cause I never know when the truck will open on its own and then someone can just steal my van. I listed the last day of all of my issues below, but this has been going on for years and still not resolved.

While driving or stationary I will lose all reception on my radio (am/fm) and just get static. The cd player will continue to work. The antenna connection is solid. While this is happening, I will also get flashing on my dash of the hazards and the motor of the heater will give off a grinding noise. I can turn all the equipment off and the car will continue to run. The radio eventually comes back and no other noises occur. This has been occurring for the last year.
