My 2017 Denali does that too. Starter, alternator and battery all are fine. GMC could not find a problem. To get around this I auto start the car from the remote and let it turn off by itself every day I don’t drive it. If I leave it sitting for more than two days my battery is completely drained.Hello I am new here
My 2016 GMC Acadia Denali was hauled into dealership today with the third drained battery.
Is anyone else having trouble with their batteries not being drained?
They are diagnosing the problem now they have had it all day,
Thanks for any information you may share.

I turn off my AC and radio when I get out of the car so it’s nothing like that. When I drive it’s usually over an hour. This just started to happen about five months ago. Last GMC I ever buy. Nothing but trouble and I’m only at 60,000 miles.
