Fuel Economy Issues With New 2017 Titan Pro4X

Has anyone else bought a new Pro4X and experienced bad fuel economy versus what the sticker is saying? I have been consistently getting 20% less fuel economy since I got the truck in mid-December, whether its city, highway and city (combined), or all highway driving. I haven't towed anything, used 4-wheel drive, and don't punch the gas. I try to use cruise control whenever possible. The dealership said the truck is fine and said the truck got up to 26 mpg on the highway when they reset the fuel economy gauge in the truck. I did the same when leaving the dealership and could not get over 20 mpg to show on the highway no matter what. The total estimated mileage remaining went from 370 to 487 after I went to the dealership so I am thinking they reset something else having to do with the software or computer in the vehicle. The next gas tank the total estimated mileage (after filling up the tank as far as I could) was back to 387 and I'm only getting 11.8 mpg on the fuel economy gauge now around town. I love the truck but need to find a solution outside of the dealership. Nissan consumer affairs won't do anything either because the dealership says there is nothing wrong.

If anyone has any ideas on something I can do or buy to get the fuel economy to where it should be (15 city 17 combined 20 highway) without voiding the 5 year/100K bumper to bumper warranty, please let me know. Thanks!
