Wiper problems of the 2014 Mercedes Benz C250

I prchased used with no visible damage to the windshield. In the inclement weather for no apparent reason my windshield began to crack as I was driving the vehicle. I pulled over as soon as I could. The crack stoped and I called the Mercedes Benz manufacture to no avail. I decided to research to see if this is common and the article says, "that the 2014 Mercedes Benz" windshields are known to crack in extrem cold and hot conditions. The windshield has continued to spider and crack in different direction. I feel threathened at this point and featful for my life that this will implode in my face while driving. I did in good faith reach out to someone.

I was exiting the interstate and making a l turn onto another highway. As I am in the turn I hear a loud pop and see that my sunroof has shattered. It remained intact and did not shower me with glass but it is cracked and bowed it on all corners and is bowed up in the center of the glass.
