Welcome to Allpar!
And welcome to the 2006 Ram Hemi Club of which I, too, am a member......ha ha. As you can see from my signature I also have a 2006 Ram 1500 Hemi. Mine has 178K miles now and I have not experienced the issue you are now experiencing. Sounds like a broken or faulty seatbelt switch or sensor in the receiver(?). Maybe try getting one from a boneyard (?). Otherwise I suggest checking with your local dealer. I've not read or heard of this issue.
