Diagnose this truck electrical problem

2019 silverado. Engine slow to turn over, AC blows hot air, radio won't go off when door opens. This all happened at once today. There's a check engine light but I didn't run the codes. Just took it straight to the dealer.
Similar issue a few weeks ago. Hard to crank and when it did crank it wouldn't go into gear. They couldn't diagnose the issue and said drive it a while and see if it happens again.
NB4 demon possession.

Sounds like you got mud in the tires.

Electrical problems are notoriously hard to diagnose. On some of these newer vehicles it could be something dumb like an infotainment center malfunction all the way to complete electrical shorts behind the dash.
But, I would start by checking the grounding strap. The 2019 have a braided grounding strap that is shitty. You also need to check the fuses and relays. After that it could be a shite ton of time and work.

I'd start by checking the ground. Bad ground will make ia vehicle do some crazy stuff

I've seen a new battery, when the old one tested perfectly fine, solve the strangest issues.
I almost miss carburetors and HEI distributors.

Test your battery and alternator. Voltage issues can cause all kinds of weird stuff.

Why? Why not a real mechanic shop?

And you took it back? Did they run the codes? I guarantee, any issue that isn't obvious, a real mechanic is going to run the codes FIRST!
I can't believe that this kind of repair would be under warranty after 5 years, so taking it to the dealer is just not smart at all.

Getting the codes is the first thing you need to do. It could tell you the exact cause of issue. Also testing the battery would be the next thing to do.

First, you should turn the thermostat down.

It's under extended warranty.

I’m guessing a software issue. Could be a short somewhere too, but it will be a bitch to diagnose.

Autozone will run the codes if you want to see for yourself.
Tell them to not clear them however if you do this.

Not sure about your truck problem, but this is a motorbike.

So many simultaneous issues suggests "computer" or the main processing center for the vehicle.
Maybe see if you can get recommendations on a good mechanic in your area. Seems the dealership would end up costing you a lot of extra time and money.

Low battery and bad alternator are the first to check

I agree GM makes shite vehicles but engines are pretty durable. My 2914 Sierra engine whose no issues ever other than coil packs going to shite in beginning. But 196k mi

With the information you have given…. It can literally be anything.
Slow starting has nothing to do with the a/c. The radio not going off has nothing to do with the slow starting (unless you don’t catch it and it’s running the battery down). The only thing linked may be the radio not going off and it not going into gear. That could be a bad door switch that is telling the computer the door is open and not to let it go into gear. Would also explain the radio not going off. Doesn’t explain the no a/c or slow starting.
You may get lucky with the code.
You either have wiring issues (hard to find), grounding issues (harder to find), bad ECU, or some random arse thing that controls a bunch of stupid stuff. MAYBE it’s the battery not supplying enough voltage and everything just shuts down.
