I have a 2019 ILX. This issue just recently started. A vibrating noise from my driver side door. I thought it was something inside the door compartment but it was empty. Oddly it only does it when it’s cold out. I believe it has to do something with the exhaust but I could be wrong.

 

Exhaust runs down passenger side though.

 

Any other ideas as to what it would be?

 

Years ago a friend complained about a noise that would stop if going over 40 mph. I went for a ride with him to see if I could figure it out. After a couple blocks I had him pull over and popped off the hubcap. A lug nut had come off and was banging around in there. "I've got this noise" isn't very helpful for troubleshooting.
