Posted this in the series 10 forum but figured I would post here to so as many owners as possible might see it.
I found something today that all of you should check. I found a set of rubber plugs in my glovebox. It turns out that these are plugs that should be installed under the car in holes located in the subframe near the rear wheels. This is supposed to be done during PDI but it is often missed. If not installed moisture can get in the sub frame and rust it. I discovered a thread that discusses this and other rubber plugs the dealer should order to install in the trunk to block the rear strut access holes. Here is the link with the specifics and part numbers.

And this one for the subframe plugs.
