WE HAD TROUBLE TOWING OUR TRAVEL TRAILER, WE LOOKED UNDER OUR CAR AND THE WELD WAS BROKEN ON OUR HITCH. WE TOOK IT TO THE DEALERSHIP AND THEIR INSPECTION CONFIRMED IT WAS A "BAD WELD".THEY WANT US TO PAY $900 TO FIX. THIS IS THE EXACT SAME PROBLEM AND HITCH THAT WAS RECALLED IN 2007 AND 2008, SO MERCEDES CONTINUED TO USE THE SAME HITCH AND WELD IN YEAR 2009 AND NOW IT HAS FAILED AFTER 4 TIMES TOWING. THE RUST ON OUR PICTURE INDICATES THE WELD HAD FAILED MUCH PRIOR TO US REALIZING IT.
