there are a number of tailgate issues from the safety strip to the hydraulics to the pneumatic pistons, to the latch to the front switch to the keyfob to the handle to the Sam. You can search this. Also do explain your problem in much more detail so we can help with the exact problem and provide the model and year. Some did not have the hydraulic lift features, does yours?

does this happen when somebody opens the tailgate using the latch? On my car, the latch mechanism binds sometimes and gets stuck in the depressed position. So I have to release the stuck handle before the tailgate will close. If I open with the key fob or the interior switch there is no problem.

It was actually really wierd....It Started when i opened the tailgate on a Rainy day..not raining too hard but raining....i noticed it wouldnt close so had to then get out and close it manually...did notice a lil bit of noise but didnt close...after pushimy it down..it closed and i could hear the locking noise finish its closing......"Suprised to see the next day when the Sun was out...The Tailgate Magically fixed itself and now opens and closes....later that night while still raining a lil i did try it again when i got the stuff out the trunk..and it didnt close as it was still raining a lil...So i guess the R350 doesnt like to close when uts Raining ?????? Lol

so... what circuits may be affected by water?
What happens if you spray water with a hose? can you duplicate the problem?
Spray selectively. try spraing just around the handle...
There is the safety strip around the edge.. im thinking that is affected by water and shuts down the system.
