Hi Everyone! I just purchased a 2015 Escalade on Saturday, and I love it. When I fold the 3rd row, the seat does not lie all the way flat. It's almost as if it angles or slopes towards the tailgate. Is this normal, or should my seats lie flush/flat? My second row captains chairs are fully upright, and the incline occurs even when they are folded. I could have sworn the one I test drove had a cargo area that was flat and level. Please advise and thanks in advance .
