Thanks for all the advice and suggestions! But I am still puzzled why this happened in 3 months in my brand new Leaf and does not happen in my Toyota Prius and Avalon, both in Phoenix over the last 18 months and several years in Phoenix. I thought recirc is the default in these also.
Part of the reason is the seal. My LEAF with vents closed leak no air...at all. My other cars (including the Prius which had the same issues) did leak some air and I had others that felt like the fan was on low speed at freeway speeds.
I think in your case, the likelihood of your driving around with all the windows closed aggravates the situation due to back pressure preventing small air leaks. My Corolla leaked like a sieve but then again it was "older" and despite the definitive clunk of the vents closing, it still had significant air flow. The Prius also had that clunk which makes me think it was an electrically operated switch of sorts that released a spring loaded mechanism but the LEAF is all electric. The delay you experience when changing modes is more than enough to figure that out.
I can only think the "gentler" closing of the vent preserves the integrity a bit better?
