The panoramic sunroof glass on my 2024 Mercedes-Benz GLB suddenly shattered while I was driving on Interstate 20. The failure occurred without any observed impact from another vehicle, object, or roadway debris. The damaged sunroof and vehicle are available for inspection upon request.The failure occurred unexpectedly while traveling at highway speed and was accompanied by a loud explosion-like sound that resembled a gunshot. The sudden noise startled me and could have caused a loss of vehicle control. Additionally, shattered glass posed a potential risk of injury to vehicle occupants and could have created a hazard for other motorists. The incident was reported to an authorized Mercedes-Benz dealership. The dealership confirmed that the sunroof glass had shattered. However, I do not agree with the conclusion that roadway debris caused the failure because I did not observe any object strike the vehicle and no supporting evidence has been provided to me. The vehicle has been inspected by an authorized Mercedes-Benz dealership and the incident has been reported to Mercedes-Benz Customer Assistance.No police report was filed because there was no collision or criminal activity involved. No warning lamps, messages, alerts, or other symptoms appeared before the failure. The sunroof functioned normally prior to the incident. The failure occurred suddenly and without warning while the vehicle was being driven. I am requesting a thorough review of this incident, including an evaluation of whether the sunroof failure may have resulted from a manufacturing defect, thermal stress, or another non-impact-related cause. I believe the circumstances surrounding this event warrant further investigation because the sudden failure created a significant safety concern while operating the vehicle at highway speeds. I am seeking a fair resolution and a detailed explanation of the basis for the determination that roadway debris caused the damage
