I've had a few things rattling in my car, and I just passed the 1,000 mile mark.
The biggest issue has been the rattle coming from my drivers door panel/window. The sound is mostly a slight ticking noise whenever I hit a bump, or shift aggressively. The noise will go away whenever I put slight pressure against the door panel.
I've also heard some noises from my passenger side, but I believe it's from my speakers. I'm not completely sure.
