My vehicle is only 7 months old. I was driving the vehicle on [XXX] in Tampa between [XXX] and [XXX] at a speed of between 55 and 70 miles per hour and all of the sudden I heard a very loud BOOM and the sound of wind. I stopped in the median and my windows were fine, but I realized that my sun roof exploded. Nothing hit the sun roof to cause it to explode. I have done some research and this has happened to other people on this same model. BMW has refused to recognize that this is a product or manufacturing defect and has refused to cover the cost of the repair. I am concerned about this, but I am more concerned that this is a safety issue. The sun roof was closed and the inside cover was also closed, so the window pieces did not fell on me. I use the car to visit my grandchildren and I am very concerned that if that would have happened with them inside, they could have gotten hurt. BMW is taking advantage of insurance laws and washing their hands, until someone gets hurt. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
