Its a 2019.
I became aware of the parasitic draw a few months after getting my AGM battery. I had been using it for a few months with no issue but when my commute went from 1hr to 10 min I noticed the battery level dropping overnight more than what I would think. Like 12.7 to 12.3 in 15hrs. That's when I added the voltage booster to help recharge the battery when driving, plus I trickle charge once a week to maintain the batteries capacity.
I did a test when initially turning off the 4R and got ~180mA draw, let it sit for an 1/2 hour with the doors locked and it dropped to 120mA. I also brought it to my car audio place (they did my remote start with app and maestro OBD) and they tested over 5 hours after removing all the aftermarket stuff and they confirmed the 180mA draw with or without it.
Maybe I am making a mountain out of a molehill, but if i let my 4R sit for 5 days the battery would be dead. Never had that with any other car, and i have an AGM battery.
