The passenger side tailgate strut failed. When the tailgate was open, the point where the struct connects to the lower bracket snapped, causing the tailgate to fall on, and injur the person below. I see that there is a recall on Nissan Rouges for "rusting tailgate struts" that seems to be the same problem, but none issued for Pathfinders. The vehicle has not been taken to the dealer for this issue or otherwise inspected. No warning lamps were present before, or after this occurred.
