ON JULY 15, 2020, I WAS INVOLVED IN A ONE CAR ACCIDENT. THE CAR LEFT THE ROADWAY ON A CURVE WHEN I LOST CONSCIOUSNESS DUE TO A MEDICAL ISSUE, AND SLID DOWN AN EMBANKMENT INTO A TREE. THE TREE PREVENTED A TOTAL ROLLOVER AND THE CAR WAS AT A 45 DEGREE ANGLE. I WAS THROWN AGAINST THE DRIVER'S SIDE DOOR AND SUSTAINED INJURIES. THE SIDE AIRBAGS DID NOT DEPLOY, NEITHER DID THE FRONT AIRBAGS. THE CAR WAS TOTALED. THE SIDE AIRBAGS ARE SUPPOSED TO DEPLOY IN A SIDE IMPACT OR ROLLOVER SITUATION, BOTH OF WHICH OCCURRED. BECAUSE THEY DID NOT DEPLOY, I SUFFERED A HEAD INJURY, BROKEN RIBS FROM THE IMPACT, AND LACERATIONS FROM THE BROKEN WINDOW AND TREE. I HAVE ENCLOSED THE POLICE REPORT AND PICTURES. THE REPORT ERRONEOUSLY STATED THE AIRBAGS HAD DEPLOYED, BUT THE PICTURES CLEARLY SHOW THEY DID NOT. I HAVE MORE PICTURES, IF NEEDED.

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
