But it’s really not the engine that’s the problem… it’s all the electronics making that engine run…or not run in this case.
I did not ask them to run a report. Didn’t think to. I did use the button to call roadside and get a flatbed.

A battery starts the engine. Not the alternator. The alternator keeps the battery charged. Without a good battery the engine and all the electronics will not work correctly. So no, the alternator does not “run” the engine, as soon as it dies or tried to restart, the alternator is useless without a battery. With all the extra voltage requirements these new vehicles need, it’s no wonder that we see so many battery issues.
So after a number of update calls from local dealer (not where I bought it) keeping me up to speed on what they were chasing down w/GM I’ve been told the problem is a faulty electronic brake controller module. Part is apparently back ordered. They told me at least 2 more weeks To get part. I’m in a new LS loaner at least so have the space but none of the options. Hopefully this fixes the issue.

The alternator runs the electrics and charges the battery. So yes it does absolutely run the car. https://www.thedrive.com/tech/7298/what-does-a-cars-alternator-do
Weird that his issue Is attributed to brake controller. We will see if that's the fix.

Dude you need to grow up. Don't get mad. It's not a popularity contest. Just a matter of who's right and who's wrong. I'm also not sure why you even comment on the 21+ forum when you have no experience with the platform.
You don't add anything meaningful to the discussion except wrong answers. And then clutter the post with name calling like a little kid.
Alternator runs the car and charges the battery. The battery only exists to start the engine. An alternator can keep a car running by its own voltage output. Battery has nothing to do with that except to be a load on the circuit when vehicle is running. If a car is started and battery dies because of a bad cell etc the car won't just die. Why do you think an alternator puts out more than 12 volts? Gotta know what your talking about. Now if an alternator dies while the car is running the car will die as soon as the battery dips below 12v.
But whatever dude over here knows things lol..smh
Here's another link to clear it up for you. It has pics too. https://theengineeringmindset.com/car-alternator-how-alternators-work/
