The vehicle panoramic sunroof came across a discrepancy that can damage the owner and other innocent vehicles on the road. Since it has been stuck on one side it can possibly break and fly off. The vehicle has been recalled, unfortunately my vehicles vin number was not chosen although it has the similar problems that the recall vehicles had. The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair.The adhesive bonding of the front panel might deteriorate, possibly causing the front panel to detach from the vehicle and become a road hazard, increasing the risk of a crash.
