2014 ACURA MDX Wheels Problems

I WAS DRIVING ON A NYC STREET, GOING OVER A SPEED BUMP AT LESS THAN THE NOTED (10 MPH) SPEED WHEN THE SPARE TIRE BROKE FROM THE HOLDER AND DROPPED INTO THE PATH OF THE FOLLOWING CAR.

THE STEERING AND THE WHEELS LOCK WHEN TURNING. IT GOES INTO NEUTRAL WHILE DRIVING

I HAVE A MAJOR SAFETY ISSUE WITH MY 6 MONTH OLD MDX (LESS THAN 5000 MILES). THE CAR IS MAKING GRINDING NOISES AND VIBRATES, INTERMITTENTLY. THE DEALER HAS DISMISSED MY CLAIMS AND MADE MINOR MODIFICATIONS WITH INSULATION, AND HOODCLIPS. NOTHING HAS BEEN DONE TO DETERMINE THE CAUSE OF THE PROBLEM AND THEY PRETEND THAT THERE IS NOTHING WRONG, EVEN THOUGH THE SERVICE MANAGER HAS HEARD IT ON MORE THAN ONE OCCASION. THE CARE HAS BEEN BROUGHT TO THE DEALERSHIP FOUR TIMES OVER THE COURSE OF THE PAST 6 MONTHS AND THEY HAVE HELD MY CAR IN SERVICE FOR OVER 30 DAYS. WHEN WE ATTEMPTED TO PICK UP THE CAR LAST NIGHT, THERE WAS NOW A NEW EXTREMELY LOUD NOISE WITH EVERY TIME I ATTEMPTED TO BRAKE. THE ON-DUTY SALES MANAGER HEARD THE NOISE AND INSISTED THAT I LEAVE THE CAR FOR SERVICE. TODAY, THE DEALERSHIP IS REFUSING TO ADDRESS THIS...
