I see a long list of rattle threads and wanted to know if anyone with an 11 coupe has this one. It sounds like it's coming from the front center or underneath. It happens when going over bumps or bad roads. It sounds like a shelf rattle or vibration. It is not coming from the rear, spare tire ok. It is not the front plates or hood. Does not appear to be coming from the glove box. I was leaning towards exhaust? If anyone can share their thoughts or places to check I appreciate it. Will be taking in to dealer who already did ride along and said they hear it also.
