I've seen a lot of traffic and post regarding the rear window coming loose or falling out. I'm from Florida currently living in Maryland and I just noticed that my window too is also started come loose around the bottom edge. Through numerous calls to car upholstry shops they said its a common problem and the cost would be about $2,000 on average to fix. On a whim I just called the dealership and they stated that there was no warranties outstanding based off my VIN. I then told them what I learned via the forum and from another dealership that the rear window should be covered for (rear window adhesion) under warranty for 10 years and/or 120,000 miles. I would you believe they said oh yes I see it now. Taking it in next week to be looked at. Good luck for those who have the same problem.
