I AM FILING ANOTHER COMPLAINT TO RECORD THIS CRITICAL DESIGN ISSUE BASED ON ALL THE RECENT COVER-UPS BY THE AUTOMOTIVE INDUSTRY. ON NOV 10TH,2013 MY VEHICLE WAS HIT IN THE REAR WHILE TRAVELING APPROXIMATELY 25 MPH BY ANOTHER VEHICLE AT A SPEED SLIGHTLY FASTER THEN MY VEHICLE. WHEN THE VEHICLE HIT US, THE HEADRESTS DEPLOYED MOVING OUR HEADS FORWARD BUT THE SEAT BELTS DID NOT RESTRAIN BOTH THE DRIVER AND THE PASSENGER. THE DRIVER SUSTAINED HEAD TRAUMA AS A RESULT. I CONTACTED HYUNDAI MOTORS ABOUT THIS SERIOUS CONDITION AND AFTER MANY LETTERS THEY SAID THAT THE VEHICLE MET ALL THE TEST DATA IN A COLLISION. WHAT THEY DIDN'T SAY IS THAT THERE ISN'T A TEST FOR REAR COLLISIONS REQUIRED BY THE NHTSB. THERE IS AN ISSUE WITH THE DESIGN OF THE HEADRESTS AND THE FUNCTION OF THE SEATBELT RESTRAINING CAPABILITY. THIS CAN ONLY BE PROVEN BY EITHER A REAR COLLISION RESULTING IN SERIOUS INJURY OR DEATH OR CONDUCTING A REAR END COLLISION AT A SLOW SPEED BY BOTH VEHICLES. HYUNDAI DID INSPECT THE VEHICLE AND THE SEATBELTS ( MEASURED THEM ; ONLY INSPECTION THAT COULD BE MADE). DO WE NEED TO SEE ANOTHER DEATH RESULTING IN THE NHTSB AND THE AUTO INDUSTRY AVOIDING TESTING TO SAVE MONEY OR IGNORE A SAFETY PROBLEM. *TR
