Radio/tape Cd Player problems of the 2016 Ford Escape

2 weeks after I purchased my 2016 Ford Escape, the radio started to turn off and on, then randomly started changing stations on its own. Also, when the bluetooth is in use, after ending a call the screen would freeze. I would then need to turn off the vehicle and take the key out of the ignition to sort of reset but now that doesn't work anymore bc the screen is black and the radio only works. The cameras do not work either.

Rear end knocking sound after and during backing up, also during low speed. The electronic radio, sync3, audio screen will not turn on in mildly cold temperatures (20f degrees).

While driving around 40mph, vehicle cut off and displayed a message: transmission not in park. After pulling over and restarting vehicle, the voume on radio moved up and down on its own while transmission in the parked position. Later that day vehicle cut off within 30 seconds of using remote starter. Dealer unable to duplicate problem or find any diagnostic codes.

Was driving vehicle at 35 mph then engine died, service engine now light came on, message center said contact dealer. Restarted after put in park. Checked for codes with generic scan tool, obd2 code p2112 in memory. Contacted dealer purchased from for service. Was told no codes, but battery had been disconnected, clock was reset and all radio presets erased and bluetooth erased.
