In that case a bad 12v battery could keep waking the car to charge it? Thus creating a drain?Do you have sentry mode turned on?
Did you use the app a few times to check the car?
Anything that wakes the car up can cause it to use power. When awake, whether with sentry mode running, or for some other reason, the car systems will use around 200 W to 300 W of power from the battery. When asleep, the drain from the HV battery is zero, as the main contactor opens to isolate it, and any remaining drain comes from the 12 V battery. If that gets low, the car will wake up and use the main HV battery to charge the 12 V battery.
But should be unlikely on a new car, maybe a car 3/5 years old or more...
