Your "paint issue" sounds like the edge of the PPF.
But when you come here saying the sky is falling and don't explain things and don't post pictures while making claims that are totally contrary to what others have experienced, then we question your motives as a new user. Many people have driven more than 9k miles with their Rivian, and the test vehicles were driven pretty far and pretty hard. (See for example
Rivian — Long Way Up). Do you drive off-road a lot or otherwise abuse the truck? You have left out a lot of details. If there were something fundamentally wrong with the design of the "frame" (which is more of a unibody), then I'm pretty sure it would have shown up by now in at least one of the other ~18,000 Rivians now on the road. And in contrast to what you are saying, Rivian has been criticized for "overbuilding" their structural members - that is, making them needlessly strong. See the Munro teardown videos for details.
If this is a one-off problem then that's more understandable because those things happen even with the best manufacturers. But the chicken little schtick - implying that the entire company is about to implode because every R1T is just days away from falling apart - is not a defensible position.
Having to tighten two bolts was a portent of massive structural failure?
