If the inside handle is very sloppy; it's likely that the 3 or 4 bolts that hold the mechanism fast inside the door have severely loosened. You cannot get to them until the door is open, unfortunately. Two of the three times I've dealt with this were fairly simple. The outside latch handle still had enough purchase on the mechanism to open the door. We were stuck inside and no one should ever ask my oldest daughter what she thought about me opening the passenger window and lowering her down there to turn the handle.
Once open it was easy to tighten the grossly loose bolts....with some Loctite blue for good measure. The third time required a locksmith who opened the door within 30 seconds.
This happened on both of my Eagles and once on the Magna. I'm pretty sure it has at least a little to do with my kids slamming the door continuously.
