Re crimp your battery cable ends. Hot/ cold dry and humid all have effects on these ends and that year had connector issues.

In my 2015 yukon XL I had a similar issue water was some how getting into the truck, the passenger floorboards always wet. I tried everything to find the leak, cleaned sunroof drains, etc, looked at AC coil nothing, taped up some holes in the fender by hinges, sealed around the battery area, so on.
In all of this I pulled off the passenger door sill and trim then lifted the carpet, in the floor rail there is a wiring harness and connector. It was full of water.
I never had anything short out but always on my mind when it would happen.
Maybe this might help your situation.
I managed to get the truck into the garage the other night, it started but most of the dash wouldn’t light up. I pulled it inside and decided to unhook the battery cables and let it sit to dry for a day or two before going back to it. When I walked behind it I noticed the out led ring of the drivers tail light wasn’t working, I bumped it and as you can see in the video it just kept flickering. I left it to sit for a couple days then it started right up and worked as it should, I drove it all day yesterday and it worked fine and I parked it in garage last night. Raining this morning, drove it for 10 minutes then parked it back inside, went out a few hours later and back to the no start issue, dash lights up but nothing when hitting the start button. My next plan is to remove tail light to see if water is getting in there.
