I have a V6 2011 convertible and have had it for about 9 months. Four days ago, I got into my car and noticed an overwhelming smell of mildew on the passenger side. The carpet on the passenger side is not wet, but the carpet smells. I'm thinking a water leak has been there for a while and it's taken this long for the mold/mildew to develop. The service center at the dealer states that he can't find the source of the water leak and can't even smell the mildew!! I've had two other convertibles and I know the smell of mildew intimately. Has anyone else had a problem with their convertible leaking? Any ideas for finding the leak?
