All I can find out is that it happens but not why it how to prevent it from happening.

That's why I decided to wrap the gray part of the rear bumper instead of installing a diffuser. It looks really good (not quite as good as a nice diffuser) and the kick trunk function works.
Only thing I can think of is maybe the way the cables were wrapped behind the oem diffuser was specific to its operation...I'm going to see about playing with it this weekend.
Cool. Let us know how it goes.
