(2016 TUCSON REAR HATCH RATTLE ) ,I too have had this same problem, and tried all sorts of things to no avail, the problem is the rear latch connecting with the striker, (metal on metal), also adjustment of the two rubber stops on either side of the hatch should be adjusted evenly on both sides, I did mine approximately two full turns out, hyundai should have put a plastic sleeve over the striker , I have had this problems on older jeeps as well, to determine if this was the problem I wrapped the striker with about 1/8 " of duck tape . And woo hoo this solved the problem.This should be an update for Hyundai to consider. I'am now enjoying my Tucson greatly. hope this helps.
