They have not fixed it yet. It just stopped. I wrote a post about how the filter was installed.

I have been putting amsoil and filter in my truck since 1500 miles. I changed it the first time and this last time, due to observations of the last dealership oil change. The filter was not leaking but I took it off by hand, no filter wrench. Maybe that was keeping my anti siphon valve in the filter from working. It has not done it since.
