How to fix

Take it back to the dealer under warranty. If there is a deeper problem, that's been covered up, there's a track record started. If you fix it yourself and you discover an underlying problem later, you may void the warranty by doing a self-repair. Best to take it back to the dealer. I can't believe it left their lot looking like that. I agree, that's more than 2 weeks old. Yes, you can fix it yourself, easy fix with new Dicor caulk. But then you won't have the fall back if you discover a bigger issues.

Edit: The more I look at that picture, the more I think that is really a c r a p p y caulking job!
