I woke up one morning and was astounded to find a long diagonal crack across the panoramic sunroof of my 2016 Mercedes-Benz S550. I contacted Mercedes and was told to bring the car to a dealership for evaluation to determine whether this was due to outside influence or a manufacturer's defect. They determined that it was a "stress crack" and stuck me with a bill for $13,000. This is a 2016 model car with 50K miles on it with a sunroof that spontaneously cracked. What if my wife and young children were in the car when it started to crack? the response from Mercedes is unacceptable. This is a very dangerous manufacturer's defect which must be addressed before someone gets seriously hurt.

Takata recall. I was driving on the highway on my way to phoenix AZ to drop off my mom and grandma when suddenly the sunroof exploded. It sounded like a gun shot. There wasn't any type of object near me to cause it. It was very random. This disturbed my family mentally scaring them and I swerved off the highway almost crashing.
