Ok, so I called my dealership on Friday morning to let them know about this issue. The guy that answered the phone was unable to connect me to my normal service writer so I told him what the problem was. The rear vent window was coming out, there is a reasonably large size gap that water could enter the vehicle. (We are in the thick of our monsoon season, and it has POURED every day since I called). He told me they were too busy for me to bring it by and I could schedule a service for Monday at the earliest, which I did. I asked if there was anything I could do to prevent water or dirt from entering my vehicle, and he told me he would recommend not touching it so it doesn't affect the paint or anything. I let him know I was comcerned about water damage and I asked if anything damaged would be covered by the warranty. He explained that the warranty would cover the weather seal but not any damage beyond (I don't understand why?). So after I took it down there today (and I switched my service writer because my original guy I got was a little disrespectful) my new service guy had it replaced by a glass company that they use for anything like this. So really all the guy had to do on Friday was call a glass company to come out. All in all it was replaced for me under warranty but it was a slight pain to deal with the bozo's in the mean time.
