New Weird Problem
This just started a week or so ago. A high frequency, fairly noticeable vibration inside the dash occurs at speeds over 70 mph. It took a bit but I figured out it only happens when fresh air is flowing into the HVAC system from the outside. I can kill the vibration noise by hitting the Recirc button or turning off the HVAC system completely. Neither the vent settings, the fan or heater settings affect it in any way, just letting fresh air in at those speeds.
I called my dealer and the service manager can't authorize one of their techs to drive at those speeds to duplicate it and they're not gonna tear into the dash w/o replicating the issue first. I sorta get their attitude. My car is still under warranty.
I checked the seating of the cabin filter and it seemed fine. I may just pull that out for now and see if it stops.
