1/21/17 APPROX NOON I WAS DRIVING WHEN I BEGAN SMELLING BURNING WIRES. I LOOKED AROUND, THE BACK-HATCH AND CARGO AREA WAS FILLING WITH SMOKE. I PULLED OVER AND OPENED THE BACK-HATCH DOOR AND THE TWO RIGHT PASSENGER DOORS. I BEGAN OPENING THE HOOD WHEN A LOUD EXPLOSION OCCURRED. IT SOUNDED LIKE THE IMPACT OF A TRAFFIC ACCIDENT. I RAN TO THE BACK OF THE VEHICLE. THE BACK-HATCH WINDOW HAD EXPLODED. BROKEN GLASS WAS EVERYWHERE IN THE STREET AND INSIDE THE VEHICLE. IF ANYONE HAD BEEN INSIDE THE VEHICLE OR STANDING BEHIND IT WHEN THIS OCCURRED THE WOULD HAVE BEEN SERIOUSLY INJURED. 1/23/17 I WAS CONTACTED BY SOUTH COAST TOYOTA. TOYOTA'S TECHNICIAN OBSERVED BURNED WIRING AND ELECTRICAL MOTOR IN THE REAR HATCH DOOR ELECTRICAL SYSTEM. APPROXIMATELY 1900 FOR REPAIRS TO REPLACE ECO, MOTOR AND GLASS. I ASKED FOR AND RECEIVED THE CONTACT INFO FOR TOYOTA CORPORATE OFFICE. *TR
