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

In my case it was an insufficient main ground connection on the drivers side inner fender, this caused the modules not to power down, draining the battery over night.

Thank you. Gonna have to check it out then I know there’s something that’s drawn on the battery overnight. I mean, I know it was -40 below, but it’s a new battery.

-40 is pretty rough, would fully expect difficulties without an engine block heater.
Yes. But it had a new battery in it and it has 22k miles on it. An older cars on my block we’re starting most likely it’s just a background wire. I’ve been reading more and more on it.
 
So the dealer called sat over the weekend started right up I don’t get it maybe because it was -40 below. It’s still cold though do you think the key because it’s too to my truck

Ground wire problems are Very sporadic! Have dealer go over it, Take it apart, clean it and replace.
Then cross your fingers.
