While driving on the highway my sunroof glass detached from the frame and flipped over to the back. It was still being held by about 5in of glue on the rear part of the frame and luckily it didn't depart the car which would have caused damage to cars behind me. This issue seems the same as NHTSA recall no. / mfr recall no. : 16v-415 / 60c3, however my VIN is not part of it. I'm reporting this because there might be other cars out there affected by this recall, which is a road hazard to other people and vehicles that are traveling behind this car.
