I discovered water in my back storage compartment and realized I had a leak from somewhere. With the garden hose, I was able to isolate the leak coming from the roof antenna. I've kept the car parked in our garage until I could determine the source rather than paying someone $175 to do it. My concern is if mildew/mold has had a chance to grow inside the roof. The car has never been in an accident or had any damage that would cause this. I bought the car new. Seems to me that this is poor/cheap manufacturing. I've bought plenty of other cars new and have never had a problem with body leaks. It's a big deal living in Seattle!
