Hi Guys,

Just got my 2012 M a few weeks ago. Loving the truck so far, except for one issues - I occasionally get a knocking noise from the tailgate area when I hit bumps or go over them in a particular direction

I already adjusted the upper stops and the lower latches to make the gate close very tightly. So much so that the auto-close almost won't close the upper gate.

It's still there.

Any ideas of what I can do to make this go away? It's incredibly annoying on what is otherwise a fantastic vehicle.
