I am writing to report an incident that occurred on Oct 17 2023 involving my 2015 Mercedes Benz S550, where the front portion of the two-part sunroof spontaneously exploded while I was driving down the highway. On the aforementioned date, at approximately 5 pm, I was traveling down Beltway 8 In Houston in my Mercedes Benz S550 along with a pack of cars. Suddenly, without any warning signs or external impact, my vehicle experienced a violent shaking accompanied by an extremely loud popping sound, reminiscent of a gunshot. The intensity of the event startled me, and I quickly maneuvered my car to safety while other drivers also reacted to the sudden disturbance on the road. Once I pulled over and inspected the damage, I was horrified to discover that the front portion of the two-part sunroof had completely shattered, leaving a significant hole and glass fragments both inside and outside the vehicle. The explosion occurred on the Beltway, before the Kirby exit. Fortunately, I escaped any injury as the glass fragments were ejected upwards due to the force of the explosion. It is important to highlight the potential devastation that could have occurred had I kept the screen under the sunroof rolled in, as is my usual practice. Considering the size and force of the explosion, it is reasonable to imagine that if the glass had come pouring down onto my head and body, it could have caused severe injuries, including lacerations, contusions, and possibly even more serious harm. In light of this incident, I am deeply concerned about the safety implications for myself and other vehicle owners who may encounter similar issues with the sunroof in their Mercedes Benz S550 or other models. It is crucial that this matter be thoroughly investigated to determine the underlying cause and prevent any potential risks or harm to future drivers.

The gear selector on the steering wheel of the Mercedes Benz has a park button on it when you change the car from gear to park you press that button. That part button has stopped working. It is a safety risk as the car cannot be parked at the end of the driving and it stays in the drive mode. I have to open the door to activate the parking which is built in to the car
