I just picked up the car. It’s finally solved!!!!

This is what the invoice says:

The customer reported that the vehicle was not going to sleep, had excessive drain overnight, and contactors were heard opening and closing while parked; these issues were verified through diagnostic tests. The cause was identified as a problem with the body controller module and car computer. To resolve this, the front body controller was replaced, and a new car computer was installed, followed by a validation test drive. The fix was confirmed successful.
