Rear Rattle, engine noise, and wind noise from windshield.

[wch X5]

I've had the rattle problem. The dealer looked at it at my one year service and told me that when they deployed the cargo cover that the rattle went away. I was skeptical but most of the rattling I heard is now gone. He also lubricated the seals in the hatch. There's been some other threads about rattles and some other fixes as well.
