Car does not turn off

The car is not shutting off after the key is removed and the power button is pressed.

• MFD display turns back on when the car is turned off.(attempted to be turned off)
• The car beeps as if the key fob is still in the ignition.
• The cars doors will not lock.
• All of this creates a drain on the battery.
• The battery reads less than 12 V with no load and 14.1 with a load
• a new battery has been placed in the vehicle – AGM
• disconnected negative cable from a fully charged battery and the next day, the battery has been drained.

Please help. please provide steps to determine if there is a parasitic draw from the system. I have a multimeter. Thanks in advance….:
