Brand new battery no start next day

[whyyo81]

I have a 2022 5.7 no E torque Still under warranty. I’m in Chicago. Park it outside go to start at the first day needed a jumpstart. I took it to the dealer. They had to put a new battery in everything fine go to start today. No start had to jump it again. Took it in there no code no nothing they said leave it. They couldn’t find why do you guys ever had a problem like this and know what it is you think? So they gave me a rental I know it was really really cold out, but I had a fresh new battery in it
