Found a minor rattle issue today -in bed trunk -in front right ahead of spare tire is a large pressure vent -I was adding mouse prevention screening to it and found it was really loose and prone to rattling -could dislodge it with a light push with one finger (2014 sport) looks like it is just a push fit into a cutout in fiberglass material that trunk is made from -bad design in my opinion -anyway I just siliconed it in and added screening -no more rattles and no chance of mice entering trunk.
