The dealership has detected the issue. Apparently it is the hinges on the deck lid. They've informed me that there is too much play in them and that it cannot be lubricated to rectify. They found this out because I gave them links from this forum where I did actually find people with the similar problem, so thanks
. If anyone ever has this issue, here are the part numbers they will be replacing.

Parts will come in soon, hopefully this sorts it out. Will update soon.
