2013 C300 Rear Deck Rattle
I have a relatively new (2013, 19k miles) C300 and love the car, but over seams or bumps in the road I have a rattle that I've sourced to the rear deck just behind the rear seats. I sat back there while my wife drove, and if I just rest my hand on the deck and apply a little pressure, the rattle disappears.
Is this a common issue? It's minor, but just sounds cheap and I'd love to get rid of it. Any ideas?
Thanks!

I think I know exactly what you are talking about. It's a very light, crackling rattle in the hard plastic behind the read seat headrests.
It has been happening on and off during winter nights for the past 3 or 4 years on my 2009 C300. The only temporary solution I have is to go into the trunk, feel for the holes and foam on the ceiling of the trunk (below the rear deck), and stuff cardboard or similar material in there in order to put more upward pressure on the rear deck. This usually works for a year or two before it would begin rattling again.
When you placed your hand on it, you applied downwards pressure. My method puts increased upwards pressure. I assume Mercedes used the foam to apply upwards pressure and sound isolation.
If your car is still under warranty, I would most definitely try to record or replicate the issue and be persistent with the dealership. This kind of cheap rattle should not be representative of a Mercedes benz, make it seem like it really bothers you and if you're lucky, maybe they'll look into it.
