I was driving my car on local streets, suddenly I heard a cracking noise from the sunroof. After that I pulled my car aside and notice that there was a small crack on the sunroof. (see attached photos) there was no falling foreign objects, no impact from the weather. I have no clue what is the cause of the day crack. My first reaction was to call the insurance company and find a parking lot to store the car. After I contacted the insurance company and I was on my way to the parking lot, the sunroof shattered completely. Some of the glass piece even fell and caused injury to my wife. This was definitely a manufacture defect because there was no impact from the outside at that time and you can also clearly tell from the picture of the crack. It is not caused by any fallen foreign object. I was not able to drive the car anymore at the risk of my family's injury so I called the mb roadside assistance to have the car tolled. The shattered sunroof not only cause diversion of the driver's attention and also cause body injury from the fallen glass pieces. Mercedes is not responding to the complain. Dealer is taking the responsibility on this issue and charge me $2,400 to repair the sunroof. I did a search on internet and I noticed that similar cases are widely seen worldwide, see below links to recent incidents in California and uk.

He bought the case to the court in California. I really think Mercedes should be responsible for this issue and evaluate the risk, consider a recall since this is not an uncommon case.
