2011 BMW X3 Rear door not always latching closed
the rear door on the BMW does not close fully and therefore will not open automatically full unless I slam it manually closed. Once I close it by slamming it manually, it will work properly by hitting the button on the rear latch door and open all the way as intended. When it is on a hill with the rear on the higher part elevation, it works fine as the weight of the door is heavy enough to get momentum when closing and no problem to reopen by hitting the rear button. When it is reversed, the door on the lower elevation if on a slight grade, it will not fully close tightly, and therefore it will not automatically open when the latch is pushed. On a level, it does the same, it will not lock tightly, therefore it will not automatically open, unless, I hit the manual release on the door rear, and push it up. Anyone know what I can do to correct this? Is this something minor, just needs more lubrication, or latch adjustment or is battery not giving enough current to close the latch?
