I dunno, I have an '09 and have regularly run the tank down below the 1/4 tank mark and have never had a problem even with spirited driving on curvey roads with and without elevation changes. I wonder if there is a problem or defect with a batch of tanks versus the overall design of the gas tank. Someone who has had the problem definitely needs to cut their tank in half and do a video for the rest of us. Any takers?
