My Panoramic sunroof front part blew off on the highway during a very cold winter day (-25c). After looking on web a saw many complaints about same thing occurring with different brand of new vehicle since 2010 and higher, because glass are designed lighter and thiner. I found maybe a lot of explanation but even there is really hard to proof to dealer what occurred, Could be a flying rock or a bad batch of glasses. Hopefully no one has been injured and not one child was behind the rear seat. So let me know if same thing occurred to one of you, for now assurance are going to pay my dommage sunroof and minor painting.
