Check the striker pin that the door latch closes around. One of the rear doors on my 2nd Gen was terribly mis-aligned at the factory. The 2nd Gens need a Torx socket to adjust. Don't remove the Torx screws, just loosen them enough to adjust the striker.
As you close the door, you'll be able to see if you have things right.
