Just noticed this today. Whenever the road isn't flat I hear this obnoxious rattling sound coming that I'm almost positive is coming from the B-pillar. Also when the base is even remotely loud I also hear this noise. The only reason I noticed it is because its right next to my head. Its obnoxious. Has anyone else had this issue? If theres no easy fix I'm going to take it in. Any other place it wouldnt bother me but right next to my ear is nerve racking.
