I've been hearing this rattling sound coming from above my left ear whenever I go over bumps/bumpy roads. For the life of me, I can't seem to isolate where the sound is coming from. I've pressed against the door panel, the pillars, and even on the seatbelt assembly but I cannot get it to stop. For the record, I have brought my car into the dealer for a different rattle coming from the driver's side door panel (which was fixed when they changed out the speaker). I was wondering if anyone else has this issue and was able to get it fixed? I brought my car in 4 times already for rattling issues to no avail so I would appreciate any input/advice. Thanks!
