THE POWERED LIFT GATE RAISED ALL THE WAY UP (AS REQUESTED), THEN DROPPED UNEXPECTEDLY ON MY WIFE'S BACK AND HEAD THEN RAISED AGAIN THEN DROPPED AND LATCHED. THE POWERED LIFT GATE REPEATS THIS UPON EVERY REQUEST TO OPEN AND WILL NOT REMAIN OPEN, MAKING THE REAR CARGO AREA BASICALLY USELESS. THE LIFT GATE IS VERY HEAVY AND COULD POSSIBLY INJURE SOMEONE WHEN DROPPING DOWN UNEXPECTEDLY. THE VEHICLE WAS PARKED IN OUR GARAGE UPON THE FIRST TIME AND THE VEHICLE HAS BEEN PARKED EACH TIME THE LIFT GATE WAS REQUESTED TO OPEN.
