2016: “The vehicle has a panoramic sunroof and I had opened the roof while I was parked and when I started driving something popped and the front of the sunroof lifted a little causing it to it the back glass portion of the panoramic roof. I pulled over to check it out and saw the the front guides were broken/detatched. I had to find a way to force the sunroof to close. I was only going around 25 MPH when the guides gave up. If I would've been going faster, the force would have broken the back glass.”
