My Model 3 has been developing a very annoying rattle over the last few months. It's something I have never heard of before... and it's starting to annoy me Unfortunately I can't pin point its exact location but I believe it's coming from inside the cabine around the rear right side. I've tried to reproduce it by touching all the different pieces in the car without any luck. Please have a look at the video to hear it. Any idea what could cause this rattle?
