Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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
