Yes, we now have this problem. The dealer was able to duplicate it and it goes in tomorrow to be fixed. You didn't mention that the opener gets soaked when the water runs from the headliner. My wife is furious. Started about when the car turned 2. So, it's coming for you...Tailgate on my 2016 Touring has been filling with water after a couple days of rain. Water runs back into headliner (via electrical conduit) when the tailgate is opened and enters cabin. Water also drips from rubber bumpers when tailgate is open. If the four plastic stoppers are pulled from the bottom, water will run out there too. Dealer had their leak expert assess and both body side seams on tailgate were leaking. Both Dealer and Honda Customer Service said this is not a known issue. Anyone else had this problem with a 2016?
