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
