The glass on the panoramic sunroof exploded/shattered under normal driving conditions. It was raining but not too heavy. It didn’t appear that anything hit the glass and no potholes were hit. It seemed to be due to pressure or temperature which caused the explosion which sounded like a loud gunshot and the glass was in pieces. There were no injuries as the sunroof shade was closed and thus the glass fell on the shade. It has not been inspected by dealership or insurance as closed on Sunday and today due to Labor Day, but yes it is available for inspection upon request. However, as it was raining and I needed to get home, I covered the entire sunroof with Duct Tape.

5 MONTHS AFTER RECIEVEING THE CAR I WAS ON THE HIGHWAY AND MY FRONT PASSANGER SIDE TIRE AIR PRESUURE INDICATOR WENT OFF. I PULLED OFF THE HIGHWAY AND PUT A "FIX A FLAT" IN THE TIRE THINKING I RAN OVER A NAIL. THE TIRE WENT LOW AGAIN SO I DROVE TO THE LOCAL MERCEDES BENZ DEALERSHIP WHERE THEY MOUNTED THE CAR AND SHOWED ME THE "FIX A FLAT" GEL COMING OUT OF THE SIDE OF THE UNDAMAGED TIRE INDICATING A CRACKED WHEEL. THEY REMOVED THE TIRE AND INFACT I HAD A CRACKED WHEEL. 4 MONTHS LATER MY FRONT DRIVERS SIDE AIR PRESSURE INDICATOR WENT OFF WHERE THE MERDCEDES DEALERSHIP CONFIRMED MY SECOND CRACKED WHEEL IN LESS THAN A YEARS TIME!

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
