Radio/tape Cd Player problems of the 2015 Jeep Renegade

I will start this off by saying I've had a few problems with my 2015 Jeep Renegade including a/c problems, power outlets(back seat 110v outlet, cargo outlets & built in flashlight) shutting off after only a few minutes of usage. The blind spot assistance will randomly pop up when driving saying �blind spot assist is temporarily unavailable� the biggest one being what's happening now which is what I'll explain below but to inform you more I'll include that it had 96k when I got the truck and had always kind of had a jerky feel when shifting between gears which I read was kind of normal, so I didn't put much thought into it until now. My truck was sitting in my driveway for 2 days without being moved and when I went to leave the battery was dead. I hadn't left anything on, lights, radio, ect. It had happened a few times before but I didn't think much of it till now. So after I charge the battery long enough to get the vehicle started it finally fires up but all these messages come across the screen: check engine, service transmission, blind spot temporarily out of service, passageway entry unavailable, along with a few more. I give it a minute having the truck running to reset these things their selves and most do except a few. The check engine light was still on along with the biggest problem which is the service transmission warning that has the truck stuck in gear; it won't shift out of park. I tried disconnecting the battery terminals for about 20 minutes seeing if the software will reset that way but it didn't help still has the message on the screen. I eventually had to have it towed to a dealership for repair. They've had it 4 days now and I'm still not sure what the problem diagnosis is but am dreading this major issue.

Transmission did not shift into gear after making a turn and returning to the gas pedal , did not shift into gear going up a hill, souding like it went into downhill assist on flat ground, rolls backwards after parked or clunks when going inot reverse also slams into first at time after take off . Heated seats turn doen or off after 25 min, heating stearing light will be on and wheel is cold, radio chamges chhanells or volume when controls arent being used, remote start doesnt always work car has been to dealer several times for repair and still not fixed and have not returned my calls to bring it back now at 36500 miles since they have not called back. Problems started around 6000 mile mark.

Stereo/infotainment center shuts off randomly while vehicle is on. When bluetooth is in use while driving, radio turns on when car is off and call is ended.
