The noise is coming from the joint right above the speakers I can't tell what's making the sound it's on both sides

 

Mine does it on the drivers side on my 2012. It is the latch that holds the top in the middle for when it is folded back. I can reach up and grab it while driving down the road and pull down on it and it goes away. Haven't looked to see if there can be a fix yet.

 

Plastic slide latch for the sun rider unlock. Mine sounds like it's coming from the rear but mine is actually the plastic slides that you slide to unlock the frame fold if you use the sun rider. They rattle on the metal frame sometimes
