yes the black strip that runs from the windshield to the back.
i just notice my passenger side half rear strip is kinda loose. i pulled it and nothing seems to hold it. tried pressing it back, now its kinda tight. wierd?.
just want to know if you notice something like this on your xB.
thanks,

 

Hmm,
Just checked.
No problems here!

 

It's just a plastic strip pushed into the groove and secured by little toothed strips at the front and rear ends. Just push it down to secure it.
