It's definitely rear driver side area, only at low rpm (not sitting at idle) and more prevalent in Comfort and Eco. Maybe the other settings keep the rpm's a little higher so not as noticeable. Very hard to explain but numerous people riding on back seat have been like "what is that buzzing sound?". It's not license plate or trunk vibration nor is it anything loose in the exhaust. I may just have a shop cut and replace the rear resonator and hope it fixes it. Or, I may just disconnect the rear exhaust section right in front of rear axle and drive it a bit to see if I can isolate the issue to that rear resonator. Wouldn't be the first buzzy resonator.

I had a slightly bent heat shield causing a buzz around the rear axle. Could be something similar?

I'll inspect it again. Thanks!
