how long have you had the car? How old is the battery? Are there any other electrical componenets (non-OEM) on the vehicle?

It was ultimately the TCU (Telematics Control Unit) that needed replacing as it would wake up intermittently and not allow the car to go into sleep mode so I would get a high battery drain warning every morning.

Do you receive any error messages? Do you have a scan tool to use to read any codes? If so, what are the errors that appear?
It may be that you'll have to find an independent shop or a dealer that will be able to diagnose the problem appropriately for you.
It could be that you one of your software programs has a bug and will need to be reset or updated.
In the meantime why don't you disconnect the terminals on the battery and leave them off for a few hours. Reconnect them and see what happens.
If this does not help, you can add a trickle charger (1.5amp) battery tender to the battery so that it doesn't constantly lose the power until you get it diagnosed. Wait for others' opinions. Good luck.
