My 2016 Rapid is a hatchback (not Spaceback) and I recently noticed water dripping out from around the two round, rubber stops when I opened the tailgate. When I prised off the round plastic clips holding the interior trim to the bottom of the tailgate water poured out through the holes.
Initially I thought that this might be from the rear washer hose either splitting or coming apart at the connection with the wiper motor but I have made a point of not using the washer at all for a couple of weeks and it is still peeing water out of the holes. Its worse after heavy rain so I'm guessing it is leaking in, but from where? The boot itself has thankfully remained dry so far.
Anyone else here had this problem and managed to solve it?
