ON 7/11/2015 WHEN I OPENED THE LIFT GATE OF MY VEHICLE, THE GATE WOULD NOT STAY OPEN. IT SLOWLY STARTED TO CLOSE. THIS PROBLEM PERSISTED FOR ABOUT 4-5 DAYS. ABOUT 6 DAYS LATER, THE GATE WAS WORKING FINE. ON 7/19/15 I OPENED THE LIFT GATE AND WAS STANDING UNDERNEATH IT GETTING MY CHILD'S STROLLER OUT OF THE BACK OF MY SUV. I HEARD A LOUD POP AND THE LIFT GATE CAME CRASHING DOWN ON THE TOP OF MY HEAD. I WAS THEN TRAPPED UNDER THE LIFT GATE AND STRUGGLED TO GET FREE (I HAD THE STROLLER IN MY ARMS). I WAS ABLE TO FREE MYSELF AND LOCATE MY SUNGLASSES (WHICH WERE ON TOP OF MY HEAD WHEN THE GATE CRASHED DOWN) ABOUT FIVE FEET AWAY. AT THIS POINT, THE LIFT GATE WAS COMPLETELY CLOSED. I TRIED OPENING IT AGAIN AND IT CAME CRASHING DOWN. CURRENTLY, THE LIFT GATE WILL NOT STAY OPEN AND I AM UNABLE TO USE THE GATE, AND THEREFORE UNABLE TO USE THE INTERIOR BACK AREA OF MY CAR. IN TERMS OF INJURY, I HAD A BUMP ON MY HEAD, FREQUENT HEADACHES, AND PERSISTENT NECK PAIN.
