I have the opposite air circulation problem with 2013-present Toyota/Lexus models. If you press the pollen filter button (which turns on an ionizer before the filter to make big particles get easily captured by the filter) will automatically set the car to recirculate to help ensure maximum filtration and minimum sneezing. After a few minutes it turns off the ionizer, but also switches back to outside air, throwing away all the carefully cleaned air and triggering a guaranteed sneeze attack after waiting long enough for you to get on the high speed freeway.
