Power Liftgate (via key fob â SmartKey). Mercedes GLB250. Was told by Mercedes employees that all cars operate the same. oSensor that automatically stops liftgate if it detects an obstruction does not retract to allow someone reaching in the trunk to safely exit the trunk. oThe liftgate stops, but it does not do so until it has hit/touched the objection or obstruction. oWhen you press the trunk button on the key fob, the liftgate only raises slightly (maybe 2 inches). oIf you press the key fob again, the liftgate just continues to go up and down within those few inches and continues to hit/touch the object/obstruction each time you press the button. Half of my body was trapped in the trunk. Suffered injury to shoulder and hand. oI was taking grocery bags out of the trunk and had the key fob in my pocket. oAn item fell out of the bag so I reached into the trunk to grab it. oAs I leaned in, the body of the car must have come into contact with the key fob and the trunk came down (closed). oI did not have time to exit the trunk and ½ of my body became trapped in the trunk. oI had just enough space to move my right hand to take the key out of my pocket. oI pressed the trunk button, but the liftgate did not fully retract. It went up slightly and came back down hitting/touching my body. oI did not have enough room to get out of the trunk. oI was in a garage where no one could hear me scream for help. oI had to push up with my left hand and use excessive force with my back a
