MY FRONT AIR STRUTS, REAR AIR SPRINGS AND SHOCKS, SUSPENSION AIR COMPRESSOR, AND VALVE BLOCK WENT OUT AFTER OWNING THE VEHICLE FOR 4 MONTHS. I'VE GOTTEN ALL THOSE COMPONENTS REPLACED AND I AM STILL HAVING PROBLEMS WITH THE SUSPENSION. MY CAR ROCKS FROM SIDE TO SIDE, LEANS ON THE LEFT SIDE WHILE DRIVING AND I CAN FEEL EVERY BUMP AND ROUGH SPOT IN THE ROAD.

THIS CAR WAS SOLD TO ME AS A CPO VEHICLE FROM MERCEDES BENZ OF GREENWICH WITH 32K MILES IN 2014. SINCE OWNERSHIP ALL AIRBAGS HAVE FAILED AND BEEN REPLACED EXCEPT THE RECALLED TAKATA STEERING WHEEL AIR BAG. THE CURTAIN AIR BAGS, REAR AIRBAGS ETC. ARE NOW ON THE SECOND REPLACEMENT. THE COMPUTER FAILED WHILE DRIVING AND THE DASHBOARD WENT COMPLETELY BLACK AND NEEDED TO BE REPLACED. THE DEALERSHIP HAS TOLD ME THAT THIS YEAR VEHICLE HAS CONTINUAL PROBLEMS AND FAILURES. IT THE SOUND LIKE THE CAR SHOULD HAVE BEEN RECALLED. I WAS TOLD TO SELL THE CAR PRIVATELY SINCE THE VALUE HAS PLUMMETED.

WERE TOLD BY A MECHANIC AT BETTEN IMPORTS IN GRAND RAPIDS, MI, THAT THE SUSPENSION WAS STUCK IN THE 'LOW' POSITION, CAUSING THE TIRES TO BECOME CUPPED AND PITTED. AFTER KEEPING THE VEHICLE FOR ONE WEEK, BETTEN'S SERVICE MANAGER SAID THAT IT WAS BAD TIRES AND NOT THE SUSPENSION. ONLY ALL SEASON TIRES AVAILABLE FOR THIS BODY TYPE ARE NOT ADEQUATE FOR WINTER DRIVING, AND MAKE DRIVING THIS VEHICLE IN ANY PRECIPITATION HAZARDOUS. DRIVER HAD UPS DRIVER TRAINING EXPERIENCE, AS WELL AS, ON THE ROAD SALES DRIVING EXPERIENCE. VEHICLE BOUNCES AROUND THE ROAD AND TIRES BECOME CUPPED AND PITTED. DRIVER DID NOT HAVE THESE ISSUES WITH ANY PREVIOUS VEHICLE. HAD TO REPLACE THE TIRES THREE TIMES BEFORE 44000 MILES. WE ARE NOT SURE IF THIS IS REALLY AN ISSUE WITH THE TIRES, OR IF THERE IS A SUSPENSION ISSUE WITH THIS VEHICLE, SPECIFICALLY, OR THE MODEL OF THIS VEHICLE, IN GENERAL. VERY UNSAFE TO DRIVE IN THE WINTER. *TR
