Annoying rattle/knock when going over bumpy road

[Shane M]

I also tried unscrewing the two adjusters fully out, and it didn’t help fyi

Thanks for the video, Dave! Our car is experiencing the exact same metal-y, rattle-y sound as you described (although yours sounds a bit like a creaking noise from the video). We've tried those two methods and the rattle was not fixed. Our dealer here in Westchester didn't know anything about it nor were they able to help. Hope you find out more with your dealer in CT.
Btw, we optioned for acoustic glass so the cabin is nice and quiet; therefore the rattle has been extra noticeable and annoying when driving around town. When we sit in the rear seats, the rattle noise from the trunk sounds extra loud!

I thought I had solved this problem by wrapping the tow bar and lug nut socket with microfiber towels. While this reduced the noise considerably, it did not totally solve it. When I first tested the car, it was warm and so I thought I had fixed it. The rattle that remains is temperature sensitive! When the car is cold, the rattle exists. After the car starts to heat up, it is totally silent. I tried extending the trunk stops, but no luck. If I find a cause, I will post again.

I agree it has a cold relation, when my car was cold I thought the panoramic roof was squeaky … but it could also come from the back …
