Outdoor smell thru the A/C Vents

I have the same issue with the recirc. Doesn't seem to work well. I am trying to replace the filter. I removed the 4 screws and it still wont come out. any ideas? please help a fellow owner.
thanks.

I am having this same issue. I suspect the door that closes for recirculating is no longer closing. I did not have this problem the first year of ownership. Does anyone know where the fresh air intake and the door that closes for recirculation is located?

My 15 did this exact same thing. The recirculate was closing fine - you can see if if you drop the glovebox and take the plastic cover off, but mine had a leak somewhere that basically sucked in outside air.

I gave the dealer a couple shots to fix - no surprise, they couldn't. Due to that and a couple of other things they couldn't fix, I traded it off.
