NHTSA Complaint #11508425 — 2016 MERCEDES-BENZ C450

Panoramic sunroof pillars/rails detaching while operating vehicle. 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. When operating the vehicle at a moderate speed, the sunroof continued to adjust itself on its own. Belive that there is a risk of the sunroof detaching from the stock plastic rails and that it may not be properly bonded. I do not feel comfortable usuing the Panoramic sunroof for fear of it detaching during driving conditions, putting other motorist and myself in danger.
