We have a 2015 hyundai sonata with a panoramic sunroof. About 2 weeks ago we opened the sunroof and noticed the wind deflector popped up higher than normal. When we tried to close the sunroof it would not close. The deflector was sticking up and we had to push it down quickly to avoid punching our hands in the sunroof. It still did not want to close after we tried, but the sunroof was down almost all the way. We called hyundai the same day to get it looked at. We thought maybe it broke something in the process of closing because it didn't look closed 100%. They could not get us in until mid August. We were not too concerned because the sunroof was mostly closed down so rain could not get in. Today driving about 50 mph the sunroof just FLEW off the car and shattered into a million pieces in full traffic. Someone could have been seriously injured!! There was absolutely no indication that the sunroof was not secure on our vehicle otherwise we would not have drove

The bug guard/wind deflector has become detached (AGAIN) on my panoramic sunroof while driving on the freeway. It puts myself & passengers as well as other people driving on the freeway in danger as there is a known issue that the detached bug guard/wind deflector is what causes detaching window panels or shattered sunroof panels. I took my vehicle to the Dealership in Salt Lake City, UT for a repair on the bug guard and was told since it had been repaired before through the original recall, they would not repair it again. (the fix is loctite super glue). I asked about my warranty on the panoramic sunroof and they told me that it only covers the glass and I would need to pay $160 for the diagnosis of the detached bug guard. - which can be seen by opening the sunroof. I spoke with the service manager of the dealership as the simple fix of super glue is much less expensive than fixing my glass and he told me it since the repair had already been made on the original recall that they would do nothing if the glass wasn't broken. There was no warning lamp or other symptoms, it just suddenly became detached while driving on the freeway.
