Had the same issue, could hear the air everytime I locked the car. I found the air leak inside the rubber between the hatch and the car body, located in the top right when you lift the hatch. I took apart the interior but it was not necessary when I located the leak. Just needed to open the hatch and pull down the top part of the rubber. A small piece of tubing was found in my garage and was just pushed onto each side of the broken yellow tubing. A couple of cable ties were also used.
