Since day 1 I had to contend with a rattle, click, clunk noise over sharp bumps. I tried all the fixes documented to date, including lowering the trunk latch and making it tighter. Removed the trunk liner and fixed the trunk light wiring vibrating against the lid, removed and applied felt tape to tail light assemblies, aaaarrrgggghhhhhh, all to no avail. I was ready to weld the darn thing shut permanently.
The noise was from mostly the passenger side in the trunk. In utter frustration, determined to get to the bottom of the issue, I removed the passenger side trunk lift strut.

That was it. For all those who tried everything and has not found a fix yet, remove the strut from the side you hear the sound from. 2 metal clips, push the clip with a flat blade scredriver carefully towards the tip of the strut. Clips pop out. Gently tag on the ends and they are out. Such a little thing and such a huge annoyance.

Guess what, I am happy.
