While driving on the highway, I heard a loud POP coming from the roof of my vehicle. I have a panoramic sunroof. I then pulled over and saw that my sunroof had shattered. The car is less than two years old. I did some research and discovered that I was not the first person to whom this happened. I contacted Jeep, and they were no help with it. They stated they were not responsible for anything and did not even care what I had to say.
