FYI - Update, it seems one unlucky person had the screen get into the valving system:
edit: link no longer works due to site change sorry.
upshot of link story was, the screen got into the sytem and messed up the VVT internals. It took the service department a while to track down and find the issue. The car just stopped running and died on the side of the road after a huge shudder.
In the end it cost almost $2K to fix.
