The screen on all buttons work just can’t get any sound for radio or voice prompts

I got my car washed and evey since then my touchscreen started acting up, it would start going places that wasn’t pressed(ghost pressing) now eventually I can’t press nothing on screen. I rebooted, (press lil reset button) I took off battery lead, the radio starts up normally but I cannot press nothing on screen… what should I do next

When driving the radio is passed 30 it turns down to 21its annoying I don't know why how do u fix that

When using bluetooth on Android or iOS devices, and you take a call and hang up, sometimes the radio gets turned on and put to the volume the call was at which needs to be at max volume to hear anything but the radio is so loud it hurts and causes a dangerous situation.
Apparently it is covered under Recall 1911, but does not apply to my VIN and the Stealership wants me to replace the radio unit instead of updating the software even though they updated the software and the version shows as XXXXX instead of the proper version because they did it wrong.
This has been ongoing since I've had the vehicle. They did a software update once and messed it up and won't fix it. They refuse to honor R1911. I have also submitted the issue to the NTSB.

Have problems with changing radio stations with my steering wheel
