I have water leaking into my car, the carpets underneath the carpet mats are soaked. I had it to the dealer 4 times they can't figure out what is going on. But doing our own testing we saw the following: Under the hood there should be a small hose coming out of the a/c drain. Ours was missing. There is water leaking on the inside of the car from the a/c unit. Water coming into the car on the passenger side under both front and back seats. Water coming into the back luggage area. We now have a very serious mold and mildew problem that has affected our health. From my research on the net, I found one man in NC that is suing GM because of mold related illness he got from his leaks in his escalade. If you have any of these problems contact GM and demand answers and action.

I bought a 2000 Yukon Denali with only $7,000 miles on it for $35,000. 6 months later, the air-conditioner was leaking onto the front board of the car. I took it in once and they resealed it. However, once again water is wetting up my carpets and mildew is making me sick. The floors get wet and so does the back luggage area. I took it back to the dealer and they will attempt to solve the problem. I love the Yukon Denali but not with the water problem - should I trade this for a new car or let them fix it again???

UPDATE: The dealer sealed it and also the back luggage area had to be re-sealed again. However they didn't replace the rug in the back that was mildewed.. they only cleaned it and replaced the liner. I called the Yukon Representative and he is recommending that they replace the rug.
