2011 SCION XB Structurebody Problems

DEFECTIVE REAR HATCH LATCH. FREQUENTLY SHOWS TO BE UNLATCHED DESPITE BEING LATCHED. CAN'T TELL IF A DOOR IS UNLATCHED SINCE IT IS ONE INDICATOR FOR ALL DOORS ON THE INSTRUMENT PANEL. HAPPENS MOST FREQUENTLY WHEN HOT OR IF THE SUN SHINES ON REAR OF CAR. INDICATES UNLATCHED PARKED OR IN MOTION.

I WAS DRIVING 65MPH ON THE FREEWAY SOUNDED LIKE PARTS OF THE ENGINE WERE FALLING OUT OF THE CAR. IMMEDIATELY EXITED THE FREEWAY. THE CAR DIED. MY SON AND I PUSHED THE SMOKING VEHICLE 200 FEET TO A APARTMENT COMPLEX ENTRANCE. THE VEHICLE THEN IGNITED IN FLAMES, AND I CALLED 911.
