I have noticed a few times that my power rear hatch will not fully close. I hit the button and it closes like it should then when I get in the Jeep the warning light on the dash is reading that the hatch is still open. I then have to get out out and push on the hatch and I feel move slightly and lock into place and then the light goes out. It does not happen often, I'd say once out of every 5 times or so. Could this be the hatch shifting out of position?
