Annoying leak around the sun roof control buttons. Anytime it rains, water drips inside of the van.

I'm not happy because the was suppose to be fixed back in 11/2006 but this problem still occurs when we experience heavy rains. now I'm being told that if will cost me $900.00 because leaks aren't covered under my warranty. I don't think this is fair. I only had this vehicle 1 1/2 years. When it should've been fix the right way back in 2006.
