RFH module is bad as well.

Certainly a possibility.

Quiet an interesting video. What he said does sound plausible.

Update 1-8-2025: Replaced battery again, replaced the Can C board and RFH module. The mechanic said it was a moisture issue. It was pouring down rain when all this happened so maybe, but it was not wet in my truck. Nothing is covered under the factory warranty at 45,000 miles. I will keep updates going.
