I had a rattle that I chased on my '24. It was the plastic cover on the bottom of the fuel tank. Under the driver side reach up and pull, knock on that to see if that is it. I put a small piece of foam pipe insulation in between and it stopped. The dealer later fixed it when I had it in for left rear door adjustment.
Found it! Backseat drivers side seatbelt connection to the seat,popped plastic cover off, it was rattling against the bolt that comes out of seat to connect the belt. Covered in foam, popped cover back on so far so good. Thanks for all the suggestions
