WHILE DRIVING TO WORK, I SMELLED BURNING PLASTIC. I ROLLED UP THE WINDOW THINKING IT WAS ANOTHER VEHICLE. A FEW MINUTES LATER I NOTICED AN ODD MELTING LOOK ON THE REAR WINDSHIELD, AND A STRONGER BURNING PLASTIC SMELL. IMMEDIATELY I TURNED OFF THE REAR DEFROST, AND CRACKED THE WINDOW TO LET THE FUMES ESCAPE. APPROXIMATELY A MILE LATER (WHILE DRIVING 70 MPH) THE REAR WINDSHIELD EXPLODED. THE GLASS INITIALLY STAYED INTACT, BUT PRIOR TO ME DRIVING TO THE CLOSEST DEALERSHIP (3 MILES FROM THAT POINT), THE SHARDS BEGAN FALLING INTO THE BACK SEAT OF THE VEHICLE. I AM GRATEFUL THERE WAS NO ONE IN THE BACK SEAT. *TR
