OP addressed your question as to why, it'd be floodgates of people with the same issue. And to answer your question, yes TONS of threads get merged into one Frequent Regen thread It is a mass of people with the same issue plaguing majority of 2022 trucks, although other years have similar issues. You're welcome to do the digging and reading for yourself. Ram is without a doubt aware of the issue and if you're right and OP is right, that they really don't know what the issue is then they're a bunch of super incompetent people. Maybe Im giving them too much credit but this screams to me something within the tune or electrical system in the emission control is the issue.
I meant grabbing an aftermarket emissions intact tune. Obviously you wouldn't do this and void your warranty but it would be interesting to see. And if Ram doesn't know what the issue is, truly, then buy the truck back and tune it themselves, see what happens. I don't trust corporations these days, at all. they'll do anything to cover their asses and make consumers deal with their failures
