I HAVE TAKEN ALL THE STEPS RECOMMENDED, INCLUDING TAKING THE CAR FOR ASSESSMENT AT A MERCEDES DEALER IN JULY OF 2017 TO BE TOLD THAT THIS SPECIFIC CAR DOES HAVE A CRACKED SUBFRAME, YET MERCEDES BENZ US IS REFUSING TO HONOR THE OPEN RECALL CAMPAIGN, SAYING THAT NO PARTS ARE AVAILABLE AND THAT THERE IS NOTHING THEY CAN DO TO OFFER ASSISTANCE.
