Tried playing with the rear controls on my 2016 today. The manual is vague in this area. What I found today was that if you use the front in dash screen to access the rear climate cotrol you will see a screen with 3 large on screen buttons labeled left to right..."Sync" "Rear" and "Rear Auto".
When I push the "Rear Auto" button it seems to let the rear climate panel it stay on the last entered temperature setting even after shuttng off the engine. I myself normally push the center button maked "Rear" and that seems to leave rear fan off complletely as I rarely have rear passengers. Hope this helps.
