What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2008 Mercedes-Benz R320, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
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 BEHALF OF MERCEDES. I THINK CONSUMERS NEED AN EXPLANATION AND THIS SHOULD BE ADDRESSED BEFORE A HORRIFIC INCIDENT OCCURS. *TR

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.
