Trouble starting my 2021 Ram 2500

[RWilk]

Stepped on the brake, waited for the pre-heat and pushed the start button, A very loud pop sounded above my left ear which startled me. Tried turning everything off and tried again with an even louder pop. I don't see any obvious warning lights or codes. Any body else experience this?

Maybe the ANC for the truck. My ‘22 did that every time I powered on my truck, very annoying.

Well after looking it up on Chat GPT I went out and spent $800 on two new AGM batteries. I guess I should have checked how old the batteries were, because that was the problem, not enough juice to start the rig, but certainly made a loud pop through the entertainment system. Managed to not lose any systeme settings and it starts and runs well at this point. Glad I didn't blow anything up.
