While driving on the highway, I heard a loud noise that, on first impression, led me to believe someone fired a gunshot at and struck my vehicle. Upon looking up, I immediately noticed it was not a gunshot but instead the glass to the front portion of my panoramic sunroof had spontaneously shattered and flew completely off the vehicle. This flying glass flew directly backwards and could have posed a deadly result for the numerous drivers traveling behind me. There were no flying objects or other dangerous instruments that struck the vehicle but the sunroof spontaneously, on its own, shattered and completely detached from the vehicle. Upon subsequent online investigation, I learned this very issue has been experienced by other Mercedes Benz drivers, with the sunroofs spontaneously shattering and flying off. Despite purchasing a extensive warranty at the time of purchase, body work, inclusive of glass replacement, is not covered. Consequently, I was forced to file an auto insurance claim, which required an immediate $500 deductible to be paid to enable the repair company to order the replacement glass. This reoccurring issue most certainly requires a recall for vehicles containing this problematic sunroof. It is not only a danger to the driver of the vehicle, but also to all others traveling on the road.

The panoramic sunroof sliding clips are plastic and break. While going down the road the roof lifted when I attempted to close it. The plastic clips broke that secure the slide rail and glass together.

Heard something crack and the found later plastic pieces of the shoe on the right side on the sunroof in the rail of the sunroof. It was the rail guide shoe. The mechanic advised me the entire roof would need to come up, including headliner. He also said you'd need to replace rails, which sounds a bit much for a plastic shoe. I agreed, it's ridiculous that these are made of plastic. 4 thousand dollars to fix it. I been seeing a lot people complaining about the same problem.

In addition to a strong, noxious, moldy odor, vehicle's front windshield fogs over so totally that it becomes dangerous in highway driving. The HVAC/climate-control system's defroster is unable to clear more than the bottom few inches of the windshield: The only way I can see through it is to wipe away the fog with my hand. This happens when the vehicle is in motion but persists when it is stationary. This happens in almost any weather, but especially if there is moisture in the air(fog, rain).
