2015 MERCEDES-BENZ S550 4MATIC

THIS CAR WAS PURCHASED IN CHARLOTTE NC IN WINTER OF 2018. IN NOVEMBER OF 2019, WHILE DRIVING DOWN THE ROAD WITH NO CARS IN SITE, WE HEARD A LOUD POP. WE COULDN'T FIGURE OUT WHAT THE NOISE WAS BECAUSE IT SOUNDED LIKE A ROCK HIT THE WINDSHIELD BUT WE DIDN'T SEE ANYTHING. WE COULDN'T FIGURE OUT WHERE A ROCK COULD HAVE COME FROM AS THEIR WERE NO CARS ON THE ROAD. THAT AFTERNOON WE PULLED BACK THE ROOF SCREEN TO FIND THAT THE GLASS PANORAMIC ROOF HAD CRACKED ALL OF THE WAY BACK. THE CRACK STARTED IN THE UPPER LEFT CORNER OF THE CAR IN THE CURVE OF THE TOP. THE CRACK STARTED RIGHT WHERE THE WINDSHIELD AND THE ROOF COME TOGETHER. MERCEDES CONVINCED US THAT SOMETHING HAD TO HAVE HIT IT. WE MADE A CLAIM ON OUR INSURANCE AND $10,500 LATER, THE TOP WAS REPLACED. 5 MONTHS LATER AS WE WERE PULLING OUT OF OUR DRIVEWAY ONTO A 2 LANE COUNTRY ROAD, WE HEARD THE SAME NOISE AND AGAIN, PULLED THE SHADE BACK TO SEE THE ROOF HAD CRACKED ONCE MORE. BETWEEN THE TWO INCIDENTS, THE CAR HAS ONLY BEEN DRIVEN 600 MILES. THE CAR IS HARDLY EVER DRIVEN AND STAYS COVERED UP IN A CLIMATE CONTROLLED GARAGE 99% OF THE TIME. NOTHING HAS HIT THE TOP AND BROKEN THE GLASS. THE TOP BROKE IN A WAVY PATTERN JUST LIKE BEFORE. THEIR IS OBVIOUSLY A STRUCTURAL PROBLEM AS THE GLASS IS A STRUCTURAL PART OF THE CAR. THESE ARE OBVIOUSLY STRESS RELATED AND I HAVE SPOKEN TO OTHER OWNERS OF THESE CARS WHO HAVE HAD THE SAME ISSUE AND MERCEDES WILL NOT STAND BEHIND THESE REPAIRS. THEY MAKE YOU BELIEVE YOU ARE IN SOME WAY RESPONSIBLE FOR THIS DEFECT. I CANNOT KEEP FILING AN EXPENSIVE PANORAMIC ROOF REPLACEMENT ON MY INSURANCE, NOW I'M AT THE POINT TO WHERE I'M AFRAID TO DRIVE THE CAR DUE TO THE ROOF POSSIBLY BREAKING. THIS IS UNBELIEVABLE THAT A $150,000 CAR WOULD HAVE THIS SORT OF PROBLEM. *TR
