A trip to the dealer is needed. Ask them to change the C-BEST setting for the 'air inlet mode' from auto to manual. There are other settings that can be changed under C-BEST as well, such as unlocking all the doors with a single press of unlock button on the remote, adjusting the auto on/off headlight sensitivity, etc.
Recirculate comes on as long as the temperature setting on the climate control system is set lower than the exterior temperature, not what the actual interior temp is. Try it, if the exterior temp is 70F and you set it for 69F or lower, recirculate will be on. If you set it for 71F it will not be on. I leave mine at 65F rather than "LO" and it doesn't turn go into recirculate nearly as much.
I agree that a complete manual system like the one in the Tacoma or Corolla would be much better than an auto climate control system. I do find myself fiddling around with an auto system more than I should and did with a complete manual system. But they can't please everyone. There will be those who will b!#ch about how their mid-$30k SUV doesn't offer auto climate control. Toyota can brag that even the entry-level 4Runner has auto-climate. Doesn't that give a warm and fuzzy feeling inside?
While Toyota could've designed it to look a little more aesthetically pleasing to the eye, it's quite easy to use the way its setup. I much rather have direct button selection for the different vent position over some other silly climate control system with a "mode" button that requires at least five button pushes to go from bi-level and floor vent position to bi-level. At least with the current system, I can switch to any vent position with a single push of a button, even fast than with the knobs on my Taco and Camry's manual system. How about those that have a up and down fan speed? Again more repeated button presses to go from full speed to low. So before we talk about So Gay ness, it could be a helluva lot worst.
Be careful what you wish for, the 5th gen will more likely than not have eliminated the direct buttons and leaving fewer buttons requiring more pushes to change settings.
Besides if the climate system is one of the few things that gets b!#ched about, I'd say Toyota did a pretty good job with the 4R.
