Lol, I totally second the pollen thing in the south and its sooo hard to keep my car clean lately.
Damn I just realized the same thing on mine and was hoping I just didnt notice it when I took delivery. I guess this is a real problem and good questions. I assume the dealer may be best to fix it, but worried they would cause more harm then good getting it resealed...
Think I'm just going to slide it back in a plastic tool for now, it's separation material and not anything that would lead to flooding so I don't think that's an issue. I'll keep an eye on it and take more involved measures if it gets any worse.
Update, so I stopped by the dealer since I was in the area and their Stinger tech was in, he said he's seen a couple but Kia said it wasn't an issue, he put some new adhesive and stuck it back under. Been a few days and a couple days of hard rain and I haven't seen it since, looks like an easy fix a not a bad issue.
