I swear I've been able to get this to work. For example: my passenger needs to unlatch the rear hatch from outside while I'm in the driver's seat. It seems I've gotten this to work if I'm in park with the car on of course...but it's hit or miss. It has definitely worked a few times with the Press and Hold of the middle button (that shows the hatch open icon) but not often enough to make me think it's an actual feature. I'm not even sure why it has "accidentally" worked. It would sure be nice if it did since it's a complete oversight that KIA has not included this useful option if that's the official case. My slightly dumber '15 Ford C-Max did this on the key fob or a button on the dash panel. It's an annoyance to have to hand the FOB to a person outside that needs to open the hatch.
