Why does climate control turn off when remote start is complete?
Checked the owner's manual and didn't see anything mentioning this:
1. Remote start the car
2. The climate control comes on and starts cooling. It cools because that's the mode last used
3. Enter the car with fob and press the on/off button to complete the remote start process
4. The climate control system shuts off
5. The engine continues to run
Why does the climate control system turn off? When it does I have to immediately turn the system back on due to 100 degree + temperatures here in the desert. That can't be good for the car on every remote start.
Is there a way to complete the remote start process WITHOUT the climate control system turning off? I checked the infotainment system vehicle settings and there's nothing there.
If I have to live with this stupidity, surely GM has a reason? They do, right?

I don't remember mine doing that. I use remote start just about every time I go to a store. I run my AC in a manual mode rather than auto mode. Don't know if that makes a diff. I do remember that the fans, inside and out, seem to run full blast until I complete the start function then they go back to normal, or what I had set them at last for the inside fans.

Thank you very much this opened my eyes. I'll test this theory today.

2. When turning the system off, how exactly do you accomplish this, meaning how do you leave the settings?

I never touch my stuff… How I had it set when the car goes off , is how it turns on , it's always blown cold with remote start. I never use auto in the settings, mines always set for 68 on a/c.

with remote start in my suburban, climate control will sense temps and either go into full AC cooling mode or full heating mode (including seat heat) when the car is remote started. Then when you engage the "key," the car returns to wherever it had been previously set. I think that the vette works the same way, and I think that was what another poster previously stated......

I have a 2015 A8, car is set to Auto AC all the time. Remote start always starts the AC and it always stays on when I get in the car and press the start button.
If yours is turning off there is something not right - could be a SW bug if its repeatable so a FW flash might fix it.

Then everything goes on, the climate control definitely doesn't shut down, if anything it starts up

The manual states it reverts to the last setting before you turned the ignition off. Mine seems to do this and it is blowing air but the ac light is not lit until I push the ignition button again to complete the process.

Only reason I have is habit. I have it set in my mind that all systems should be turned off before you hit the button to turn the car off. You just power down the car with the AC system running?
I guess this goes back to cars of previous generations where everything was a manual or mechanical system. I'd have to assume the computer in the C7 knows how to handle a power down situation if the AC is running,
It's all in my head.

There's nothing like pressing the button and hearing the beast roar to life from across the parking lot.
GM must have a good reason for limiting it to the A8. I'm just not sure what that is. As you said the M7 could require the car to be out of gear and the electronic parking brake to be set in order to engage remote start.

I absolutely love remote start. As much as I vacillated between the A8 and the M7 remote start was not even a thought in my mind to sway me towards the A8. Now that I have it, it's a huge enjoyment that would have weighed heavily in my decision had I realized how awesome it is.

Yes I do not turn anything off before turning the car off.
Remote start is awesome, pretty much anytime, hot or cold.

I can't even tell mine are working when I manually turn them on. It's probably related to the 100+ degrees we commonly saw over this summer. I'm thinking they don't do enough to be felt when battling that kind of heat. I wonder if you are experiencing the same problem in simply being able to tell if they are on in these extreme temperatures we are dealing with? I even had them checked when I last had it in for the seat cover replacement and they we're verified to be operating normally.

Kevin, obviously you don't think like a corporate lawyer. 
The owner's manual tells you to put the car in reverse or first gear when parking. This is to keep the car from rolling in case the ebrake fails. If they allowed the manual cars to be remote started they would have to remove the leave it in gear when parked instructions. The first time an ebrake fails and a car runs over a little old lady, GM gets sued.
