I didn't even have mine for 2 days and I had to return it because my passenger side was making this very load whistling noise. Come to findout the manufacturers didn't put any sealant in the one corner of the panoramic window. So, I was lucky it hadn't rained. They fixed it but I had to drive their multi-colored advertisement car for 4 days. Oh my Goodness!!! I have never been approached by so many people. And some strange looks too.
