Has anyone had the issue where water starts dripping from the bottom of the back tailgate when fully opened? There is a rubber peg-type piece and a fair amount of water (not windshield wiper fluid thankfully) dripped out of it when the tailgate was fully opened. This was after a rain storm and happened a couple of days ago. It hasn't rained since and the water is no longer dripping. Should I bet concerned that i have some sort of seal issue and take it into the dealership or is there a chance this was just an anomaly and it's all good. Thanks in advance.
