What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 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.

TAKATA RECALL / NHTSA RECALL # 16V-081 - MERCEDES SENT A LETTER ABOUT THIS RECALL BACK IN MAY OF 2016 AND THEY STILL DO NOT HAVE A SOLUTION OR TIMEFRAME FOR WHEN THEY ARE GOING TO REPLACE OUR AIRBAG. NOW THAT TAKATA HAS FILLED FOR CHAPTER 11 BANKRUPTCY I AM CONCERNED THAT THEY EVER WILL AND GIVEN THE NATURE OF THIS RECALL ALONG WITH THE AGE OF OUR VEHICLE THIS IS VERY TROUBLING. MERCEDES NEEDS TO MAKE REPLACING THESE AIRBAGS A PRIORITY

TOWED VEHICLE TO A DEALERSHIP WHERE THEY TOOK A LOOK AT IT. THEY SAID IT LOOKED LIKE A PART OF THE CAMSHAFT BROKE OFF, GOT CAUGHT IN THE TIMING CHAIN, BROKE BOTH CHAINS, AND CAUSED COMPLETE ENGINE FAILURE WHICH WOULD REQUIRE REPLACEMENT. *TR
