While driving my 2016 Mercedes-Benz C300 on Route 12 in Utica, NY around 8:10 PM on May 29, 2025, the panoramic sunroof spontaneously exploded while in the tilted vent position. It sounded like a gunshot and sent glass raining into the cabin, causing multiple cuts to my hand, ear, arm, and lower back while I was driving. The shock nearly caused me to lose control of the vehicle. Conditions were clear and dry, around 60°F, and I was driving about 50–55 mph. I have reported the incident to Mercedes-Benz USA (Case #14443457). This is a serious safety hazard, and I am concerned about residual glass in the vehicle’s ventilation system and potential future injuries. I am also concerned about paint and interior damage from the explosion.

The complaint is about the sunroof which has an open recall with all warning signs and risks exactly identical to my make, year and model (2016 mercedes benz c300). More than 15,000 vehicles have been affected by this problem and the warning signs suddenly appear with the vehicle. Mercedes Benz after their investigation after several reports were filed, later found that the sunroof glass panels were installed without prior application of the primer (bonding agent) which was supposed to ensure the specified strength of the bonded joint. the federal safety agency received several complaints concerning this issue where the sunroof suddenly began shaking and rattling which began with the driver noticing excessive wind noises in the area of the sunroof while driving indicating that the panel might be partially separated from the vehicle. I began noticing this on Tuesday May 28th, 2024, when my sunroof tilted open on the left side and failed to open properly. Upon closing it, I began to drive, and the wind noise and excessive rattling was immediately noticeable. It sounded like the wind was forcing open my sunroof and was almost like the wind was about to pull it out. In fear, I slowed down to about 20mph, but it was still very noticeable. I got scared and immediately pulled to the side of the freeway and parked. Then I immediately looked up the issue on google and noticed that there was an open recall for the exact same issue, for my make, model and year. It was noted that the roofs if not fixed will eventually pull out and flyaway posing a safety risk to the driver and other motorists who may crash as they try to avoid the debris or if the panel hits them. Luckily, I pulled over quicky out of fear for it felt like my sunroof was literally about to pull off by the wind. Now I am unable to drive my vehicle because of fear for my safety. Please I would appreciate if this were resolved and for my vehicle to be recalled and fixed immediately as soon as possible. Thanks.
