Body problems of the 2011 Mercedes Benz GLK350

I was driving in highway with speed of 60 mph and suddenly the driver side window dropped down and due to sudden air coming insude, my car was shifted and I drove to nearest exit and no matter how hard I tried, I was unable to pullup the window and took it to mechanic and he noted he has seen this several times before and the regulator suddenly malfunctions. The cost is estimated $1,000 to fix it. I would like to warn that I am a highly experienced driver, if this incident would have happened to a driver with less experience, it could be very dangerous. My insurance decuctible is $2000 and cost to fix it $1000.

I was driving on the interstate, and I heard a very loud boom from my vehicle, followed by crackling sound. My sunroof shattered as well as the fixed piece between my windshield and moving pane of sunroof. The following day, I drove the vehicle to a local dealership and was told an object struck the vehicle and caused the damage to the vehicle. The first pane of glass had a 1 in diameter hole with a starburst pattern and the second pane had very little visible damage to it other than the hundreds of cracks in it. I am concerned about why the first pane of glass that is angled outward to the road is not made of safety glass or metal and was constructed of tempered glass. I was lucky that I had my blind closed and that the glass did not separate from the vehicle and strike any of the vehicles behind me. As I told the gentlemen at the dealership, if road debris hits my vehicle I should not have to replace a third of my roof. Rocks have hit my windshield and chipped it, but for a rock to hit my vehicle and cause such extensive damage is poor design or quality of manufacturing.
