There is an active recall on the 2015 Mercedes S550 for the Front Stationary Sunroof panel however my vehicle is not part of the recall due to the Vin#.

I bought my S-class car at a Manhattan dealership with 4900 miles on it, I treated it like my baby I’m the only driver and all services and maintenance had been done at the dealership, and I started getting bad readings on the fuel, check engine is ON, fuel gauge reads Full then goes down to Empty The mechanics at the Manhattan dealership said it was short on the fuel tank and I need to have the whole new tank replaced, my understanding is this model, the S Class has been having this issue on many models and there was a soft recall on that matter and it can be fixed at the dealership, we do have a case number with the Dealership. case number 03656172

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.
