It was removed because it was a feature that would not ever be used and removal saved almost $400.00 so dealer was asked to remove it. The genius removing it removed the bumper w/ the hitch. One guy at the dealership said hitch should have been removed at the body shop and not at service department which is a dealership communication problem. Looks like somebody would have noticed the guy was carrying too much in parts for just a trailer hitch removal.
Edge is being repaired and it will take until Tuesday because the body shop (which is not at the dealership) had to order the parts since there was damage on the body panel behind where the bumper should have been (not sure what this area is called). This will be replaced at the dealers expense. The body shop guy said it could be bent out and fixed, but since it was a brand new car, it should still be fixed like a brand new car.
Basically the minor rear end collision (even though it has been a week of hassles with everyone figuring out what was wrong, why it was wrong and how to make it right), was a blessing in disguise. According to the body shop guy, had the rear end collision been a major one, damage to car and passengers would have been serious. Scary to think how long we could have been riding around without a rear bumper.
So to answer your last question, between the Dealership and the insurance company everything is going to be made right thanks to the body shop staying on the dealership.
