Radio/tape Cd Player problems of the 2013 Hyundai Sonata

It started with random electrical/wiring problems. Radio volume, ac suddenly stops working, then starts again, etc. . . Now it starts or doesn't start at random. When it doesn't start, I wait a few minutes to an hour, then it randomly starts without any battery jump or other assistance. Local mechanics are not able to diagnose this issue but tell me it is a common problem with these cars.

The trunk no longer opens automatically when pushing the button on remote key and/or trunk button inside the car. Additionally, the car's display system no longer operates properly and when touching the screen to select an option, it operates a different function then pressed. Such as. Selecting volume up might change the radio station instead. When pressing the screen to select a different mode for music, screen went completely black while navigating (car in motion) and was no longer operable. The rear view camera has failed as well and when the vehicle is put in reverse, there is merely a blue screen and no visual of the rear. I had an error message display on the screen on 15 July 20, but I am uncertain if this is relatable.

After parking car and turning the car off, key would not release, key stuck in ignition, key works fine, car drive fine, however unable to remove key from ignition. ( key will not turn pass accessory. Car shifts gears, steering wheel will not lock, key cannot be removed. I had to un plug the fuse to radio/ assessories to remove/release key.

There are text messages on my radio screen and extremely loud popping from the antenna and in the vehicle. This is startling and distracting and I have almost plowed into other vehicles when it occurs because it sounds like a gunshot. The car was involved in an accident rear ended in 2018 so I don't discount there isn't an underlying electrical problem. I paid for a new antenna and the problem still present. The dealership states the issue cannot be resolved and the car should have been salvaged post accident due to the lengthy process of trying to detect an electrical issue. The insurer has not addressed the problem. I'm asking now, for the government to assist. Thank you very much.

First- airbag light comes on randomly driving, in park or reverse. Second my interior light is in door mode does not go off as it should this is random as well sometimes it will go off other times it does not. I have to keep it in off mode - not fun at night leaving in dark for work or loading unloading babies. It has to stay in off mode so battery doesn't die. Third- cruise control once again random sometimes I can get it to set other times I cannot some times I can pull over park turn off and attempt again and it still doesn't work. Fourth- car wouldn't start , not battery related some interior lights worked some didn't radio didn't clock did all dash lights worked trunk would not open via inside button or ke button, gas tank would open with button. The door open alarm would ding. Fifth- odd sounds best described as grinding brakes fan belt movement that's broke and this is louder and louder then stops also has odd smell at the times of occurrence -dealership claims nothing is wrong obviously something is. These have been different occurances sometimes more than once at the same time. Some occurring for a couple of months now.

Upon start up the vehicle is pretty loud to be fairly new, the noise increased by day. Brakes would grind. No control over steering car would pull and drift as driving. Remote barely worked radio would randomly increase and decrease.

Radio volume control button on steering column either doesn't work at all, mutes the radio or cause the "please say a command" prompt to come on. The please save a command prompt button is two button downs from the volume control button. This happens several times during the week. It does not seem to have a pattern. This been happening since owning the car.
