2019 RAM Bighorn 5.7-No Power

[RedSox10NG]

Hello all. Recently replaced a dead battery and put about 3k miles on that battery.

Very recently, a check engine light came on and showed codes: P0456 Evap System Small Leak and C2206-00 Vehicle Configuration Mismatch and U0403-00 Implausible Data Received from T-Case. Also showed Battery Voltage at 14.18V, but I believe the truck was on for that measurement

We cleared the codes and truck ran fine for a week.

Wife goes to start truck today and there is 0% power. Doors would not unlock. Nothing happens when pushing the start button. Tried jumping it and nothing. Pulled fuse F24 (15A) to let computer reset, nothing. Alarm and hazards sounding and blinking.

We are so scared to bring it to a RAM dealer, as ours is known for terrible service, but I am past my abilities to troubleshoot. Any thoughts or input is greatly appreciated, as it is the only family vehicle that fits all children.

Thank you for any help!

Any water intrusion in the back of the truck? If so, could be that the RF hub has been damaged, or a poor ground connection perhaps.

Not that we're aware of. But both the tow operator and locksmith believe it's RF hub related. We have decided to tow it to Dodge and have them diagnose it. Completely gutted at this as its our family truck and tow vehicle. I've been out of town working and my poor wife has been trying to sort this out all day. Prior to this, truck has run great, with routine maintenance and oil changes.
