I had parasitic draw that was draining the battery in 2 days. Turned out to be the bose amp not going to sleep all the time. You could hear it still hissing slightly if you listened at the soeakers after waiting 5 mins for the car to go to sleep. It didn't fo it every time sometimes it slept properly. GM replaced the amp under warrenty.

I'd also be interested to see if anyone has a more tractable testing process than the only one I can think of, hooking up a multimeter and pulling fuses one by one to see what happens in the car 5-10 minutes after shutdown. Neither the hood nor the trunk lid should prevent the systems from going into full sleep.

Well, since we know that software updates can continue for, I believe, 30 min after the power is turned off, it makes sense that such activity consumes a bit of power.

Just for clarity, using a multi-meter set to DCV, negative lead on ground and positive lead on a particular fuse, the meter should read according to the chart? I'm wondering what 179mA DRAW will look like in mV?

I'm still stuck. Range disconnected. Got 178-183mA draw with only the trunk open (light disconnected.) The draw changes from 178 to 183 about every second. Seems like some device is "searching" for something. I got in contact with a dealership to try to get a "spec" on "normal parasitic draw" but was unable to get an answer.

Battery dead in 2 days
Someone has mentioned this before and it sounds ridiculous, but shut the wifi off in the radio settings. My car would randomly go into key learn mode, a no start situation yet the key fob worked fine to lock/ unlock/ trunk pop/ panic, even putting the key fob in the rear cup holder did nothing. Holding the start/stop button for 12 seconds took it out of the learn mode and the car started every time. 2 dealer visits with not much help, they disconnected my wireless charger, came home, the next day the car is in key learn mode. It has been over a week with wifi shut off and I have absolutely no issues. A day before I shut off the wifi I went out at night after a no start issue to see the backlight of the radio on and the power button ring lit up for well over 5 mins. There is some kind of wifi connection issue.
