Thanks for your reply.Actually, I have the opposite issue. At times, when I'm standing and loading things, I guess my movement trips the foot gesture area and the door begins to close even though I'm still loading things!
Given my tribulations with this feature, I made a few observations.The actual area is very close to the edge of the bumper and not deeper into the vehicle. A quick "hokey pokey" foot in and out seems to trigger it best, not a sweeping side to side motion. And, as I mentioned above, you need to stay away from that area when loading/unloading or the hatch will start closing on your head.
