So it doesn't look like this is something that folks have seen before. I'll go ahead and provide some extra details in the event that somebody else runs into it later. I taped off the section I suspected was the entry point with some good ole fashioned duct tape (not the cheap plastic kind..
). The water now runs down the tape and drips off onto the ground instead of running into the underbelly. It's been dry for the last couple days now even with some pretty heavy rains so that confirms what I thought was the problem.
I dropped it off at the dealer today for them to look at how to go about sealing it up. I'm less than a year into the warranty so it should be covered. Guess we'll see if that's the case or not. It doesn't look like there is normally any sealant used around the edge of the underbelly when it's installed. Given the way I see the water flowing here I don't think it will stop flowing underneath without some sort of sealant being used.
