There is a rattle somewhere back right. It does not always rattle but I have heard it when I am stationary and the A/C comes on, causing a slight vibration in the car. I also hear while driving on city streets that are not smooth. I have checked that it is not something in the spare tire well. Does anyone have any ideas where I should look. I think it is inside the car, but not sure. possibly in the hatchback door.

 

I have used some cushions or rubber bumpers to place on the backside of my license plate to eliminate a rattle. As far as inside, have you checked the metal tie down clips? Maybe they have loosened?
Hope you find it, I've got some new noises too haha

 

Thank you! It turned out that it was the license plate. Not sure why it just started rattling and hadn't before.
