I BOUGHT A USED EXTANG TONNEAU COVER OFF OF CRAIGSLIST AND INSTALLED IT ON MY 2014 TOYOTA TUNDRA. I WAS CRUISING DOWN THE HIGHWAY AT 60MPH AND KEPT HEARING A FLAPPING NOISE BEHIND ME BUT DID NOT SEE ANYTHING IN MY REAR VIEW MIRROR. AS I CROSSED ONE OF THE BRIDGES, I HEARD SOMETHING LIKE A BIRD HITTING THE WINDSHIELD AND IN MY REAR VIEW MIRROR, I SAW MY TONNEAU COVER COME OFF THE BED OF MY TRUCK AND ONTO THE ROADWAY WHERE IT EVENTUALLY WAS RUN OVER BY A MOTORCYCLE CAUSING THE DRIVER TO LOOSE CONTROL AND WENT INTO THE CONCRETE BARRIER DIVIDING THE HIGHWAY. I PULLED OVER AND CALLED THE POLICE SINCE THE DRIVER OF THE BIKE APPEARED TO BE INJURED. I THEN CALLED MY INSURANCE COMPANY TO INFORM THEM OF WHAT HAPPENED AND FILLED OUT A POLICE REPORT BEFORE LEAVING. I WAS SEARCHING THE INTERNET WHO I COULD CONTACT ON THIS AND FOUND THE NHTSA WEBSITE. UPON FURTHER REVIEW ON THEIR SITE, I FOUND THAT EXTANG HAD SUBMITTED A SAFETY RECALL ON THIS EXACT SAME ISSUE AND CALLED TO TELL THEM WHAT HAPPENED. SO FAR, ITS BEEN 2 WEEKS AND HAVE NOT RECEIVED A CALL BACK. WHAT DO I DO NEXT?
