I THANKFULLY TOOK MY CAR TO HAVE REGULAR MAINTENANCE (SERVICE B) COMPLETED AND UNFORTUNATELY DURING THAT INSPECTION, THEY FOUND THAT THE RUBBER CYLINDER ON THE HARMONIC BALANCER WAS HANGING OUT. THEY AND I LOOKED TO SEE IF THERE WAS A RECALL (SURLY, THIS WOULD WARRANT A RECALL). THE CAR IS WELL MAINTAINED AND ONLY 44,856 MILES ON IT. FAULTY PART? CAN'T FIND ANY ANSWERS... I HAD TO PAY $900 TO HAVE IT REPAIRED AS DRIVING THE VEHICLE IN THAT CONDITION WITH MY BABY INSIDE IS BEYOND IRRESPONSIBLE. HAD IT FAILED BY BLOWING APART WHILE ON THE FREEWAY, PEOPLE COULD HAVE BEEN KILLED BY METAL PARTS SCATTERING, OIL. FUEL AND CAR PARTS CAUSING A FIRE AND ACCIDENT HAZARD! WHO WOULD BE HELD LIABLE?? I PURCHASED THIS VEHICLE FOR SAFETY FOR MY FAMILY AND CAN'T IMAGINE THAT THIS IS NORMAL WEAR AND TEAR FOR A MERCEDES. I DO MY PART AND ALWAYS HAVE REGULAR MAINTENANCE DONE. AM I SUPPOSED TO HAVE THIS PART REPLACED EVER 44K MILES?? THIS IS SHOCKINGLY DANGEROUS AND VERY DISAPPOINTING ON BE
