Just a heads up, when my wife and i were test fitting a new baby seat into her 18 Terrain, i looked down and saw that the Aux seal is coming off the vehicle and has swelled up so no chance of putting it back in. This is the Seal that extends down the back of the door and up around the rear wheel well. On the off chance, i looked on the other side and it was also coming apart in the same fashion. I will contacting the dealership to see about addressing this. I will keep the board posted.
