Clunky rattle
2021 RAV4 prime SE, 26,000 miles:
I've developed a clunking rattle somewhere in the rear. Sounds exactly like the tire changing equipment is loose, but I have emptied the spare tire well and completely rubberized everything in there. Nothing moves, nothing clunks. Yet the noise remains. It's not the body panels, not the license plate, not the rear seat latches. Nothing is loose in the door bins or any of that.
I have not removed the battery cowls or jacked up the car. Before I get into that, thought I might check with all y'all to see if somebody else has had this issue.
