I was on a road trip over Memorial Day weekend and was bothered by this issue. I never notice any smells from outside the car because I keep the vents set to recirculate, but when driving by a deer carcass in the middle of the road, I could smell the rotting odor seeping in. All windows were closed and a/c was on. This was so strange...has anyone else experienced this with their Sienna? Thanks.

Strong odors seem to seep in a bit; I've noticed this on most cars. I've even resorted to opening up outside air circulation after the stink was well passed by to freshen up the air.

I'm confused...did you think that running on recirc made the car airtight? That would tend to lead to breathing problems...

Seriously, of course there's still lots of fresh air coming in even on recirc, so this isn't surprising. Stay away from rottting deer...
