2012 ram 1500 crew can 5.7L stuck in limp mode

[2012 BlacK LL]

first off, this truck is lightly used and baby’d. 90k miles. All of a sudden, it starts throwing codes, left and right. Check engine light, charging light, air bag etc.. then it goes into limp mode.

Does anyone have any idea what would cause so much crazy behavior and all over the place?

It’s at the transmission shop and they are checking it out now.

I've seen low battery voltage cause some pretty crazy things. That would be one of the first things I'd check, #1 because the problems started all of a sudden, and #2 because its easy to check.

Battery? All these new truck/car everything is electronic. Once they dont have proper volts parts dont run right. Lots of fail safes to keep you truck from fully breaking. I know the first generation allison transmission had a electric valve body if your battery was done you could grenade your transmission.
