I checked, but did not find any TSB's pertaining to this issue on an Escape.
It is possible that the little rubber grommets or stoppers that support the rear glass hatch window are missing or if not missing, the grommets themselves have a dry rub causing the noise/rattle. You may want to check to see if any are missing, if not, then perhaps a small amount of grease or even Vaseline or Chapstick applied to the rubber grommets will quiet it down.
If I recall correctly, the only thing adjustable is the latch assembly and one must use caution when adjusting that.
Perhaps another member more familiar with the Escape’s can better assist you on this subject.
I sprayed the entire rear window weatherstripping and the liftgate rubber stoppers with white grease and it completely eliminated the annoying creaking sound I had when driving slowly over rough roads. mThanks for the suggestion.
Just a suggestion; a better alternative to grease would be food grade silicon lube, used in scuba diving dry suits. Totally safe for any rubber or neoprene seals on the vehicle. It also stops the seals from deteriorating and breaking down (rotting). Non messy and non staining, too.
:yesnod: Wow, this really works. No more liftgate rattle on my 2010 Escape. I used a slit piece of shrink tubing (seems to be fairly durable stuff), glued it to the striker post with spray adhesive and put two wraps of tape over that. As the previous poster said, so what if I need to refresh this fix every so often.
As luck would have it, I also fixed a rattle behind the radio that has been there since we bought it new. Drove us nuts. Been to the dealer several time (of course), and you can guess how that went . Anyway, I finally decided to take the bull by the horns and pulled out everything from the center dash area (radio, HCAV controls, upper air ducts, etc. Finally found the source of the problem. It was a loose screw that holds the metal radio frame to the left center AC duct (among other things, I think). Once I figured out how to get to the damn screwhead to tighten it (nothing trivial), the problem was cured.
