Engine Noise 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.

Around 37,000 miles, check engine light came on, shortly after purchased, light would go off and on periodically. After a several weeks light stayed on and started blinking, at this time van was vibrating and sounded like it would cut off. Dealership ended up replacing engine head under warranty. A few months later light came on again, van did not want to accelerate, dealership could not find anything wrong with van. At times van does not want to accelerate as it should. After a delay, it will accelerate, but not like it should. Around 60,000 miles, abs light and traction light have come on and cruise control will no longer work. Back hatch door of van locked while open and would not shut. The door had to be tied down from the inside in order to drive it to the dealership. Dealership says hinges have been bent. Hinges have no marks of any kind, and there has been no damage to the vehicle. There's a whole lot going wrong for a 2012 vehicle.
