I'm posting here in hopes of finding help to see what I need to do to fix my 2020 Chevy Traverse.

It had a rumbling noise coming from the engine for a while now. I took it to the Chevy dealership here and they couldn't even pinpoint what was the problem with it. They just told me that they need to run more diagnostics which would cost me even more. Did anybody here ever run into this problem before?

I'm going to post the other pictures of the codes I got in the comments.
