Which year did you get ?
The Monroney sticker by law is only required to be posted before buying the car.
The sticker can not be replicated or printed out by anyone other than the manufacturer.
I always ask for the sticker to be folded and put into the glove box in the event I want to sell the car....
As for the 18" wheels - they are standard on 2016 HSE. Upgrade to 19" are $1500.
As for the 2015 model year, the 19" seems to be the standard for HSE trims.
I know, because I am in the middle of negotiating between a 2015 HSE w/ 19" wheels versus a 2016 HSE w/ 18" wheels.
I am stuck because the 2015 has the color (Loire Blue) and wheel (19") but missing the climate comfort option.
The 2016 is white, 18" wheels, and has the climate comfort.
Both of them share the other options I needed: 3rd row (5+2) seating and Driver Assist Plus packages....
