THE TRUNK DOOR CLOSED DOWN ON ME AND THE SENSOR DID NOT SEND A SIGNAL TO MAKE THE DOOR GO BACK UP. I WAS PINNED DOWN TO THE BOTTOM OF THE CAR AND HAD TO PULL MYSELF OUT VERY QUICKLY, BUT NOT WITHOUT MINOR INJURY TO THE BACK OF MY LEFT ARM. THE VEHICLE WAS TURNED ON AND IN PARK, IN A PARKING LOT. I WAS UNABLE TO POP THE TRUNK, WHEN MY HUSBAND PRESSED THE BUTTON TO MAKE IT AUTOMATICALLY GO UP. THAT'S WHEN, AFTER LEANING INSIDE THE VEHICLE, IT STARTED TO GO BACK DOWN AND DID NOT STOP WHEN THE DOOR TOUCHED ME.
