Gas mileage on my 2016 Pathfinder is 100 miles less per tank than my 2014 Pathfinder.

In September my two-year old 2014 Pathfinder Platinum was totaled (while parked on the road!) and I ended up getting a new 2016 Pathfinder Platinum - same exact car. Pretty much immediately, I noticed that the 2016 seemed to rev more aggressively and appeared to run in lower "gears" and at higher rpms than the 2014. Even upon start up it seemed that the first rev was much more aggressive than the 2014.

I just assumed that the 2016 was tuned differently and went on. By 1500 miles I knew something was wrong. My gas mileage could not get over 15.5mpg. This was on the display. When I calculate manually, I get about the same number, slightly lower.

My 2014 Pathfinder could get over 20mpg when highway driving. I have been doing the same 350 mile trip that is 95% highway miles and cannot get over 16mpg on that trip! Full tanks on the 2016 get from 240-260 miles on a full tank while the 2014 used to get 340-360. Nothing changed with our driving behavior and habits. I have to fill up noticeably more and our gas expense has increased 30-40%.

I took it for service at 1750 miles and no codes came up. They suggested I give the engine time to break in and get used to our driving habits, but really were unsure about what was happening because the part numbers are the same and there should be no difference between to 2014 and 2016 engine/transmission.

It is now over 4000 miles and the same problems. I average under 15mpg on the highway and under 13mpg in the city. I have done the same 350 mile highway trip 8 times with the same result on the 2016. Our mileage with the 2014 per tank on that trip was consistently different.

My next appointment will be on 1/12 days, but I know they'll pull no codes. I've asked them to make another 2016 pathfinder available so I can compare the drive because the difference when you even lightly depress the gas pedal is significant, and I want to try it on another new 2016.
Today I filled up. I drove 181.5 miles and got 10.8 mpg. It was 181 miles of 60 miles hwy and the rest city. Something is wrong with this new pathfinder.

Has anyone had this problem?

Any ideas on what is causing the problem?

Not only is the gas a major issue, but the drive is also too aggressive (ex. unwanted torque oversteer). I want my 2014 back!

my used 2014 pathfinder have same problem... local/highway I get about 16mpg. the display on the dash would always say 18-19mpg , but the navi screen would calculate 15.5-16mpg and I also did hand calculation with putting gas and gas B - Gas A divide by gallons filledup.. I would always end up with 15-16mpg... since my car is out of the 35k mile warranty, do you think this can be cover under the power terrain warranty ?

I think this is a good idea if they will accommodate you. Keep careful records so you will have a basis for comparison. If you follow the lemon law protocol for your state, you will have a good case for possibly getting your Pathfinder replaced.

Thanks for the responses. It's in the shop right now and they're replacing the CVT valve lock. Not sure it's related but the thought process is it may have been the problem. Unfortunately, they didn't have any 2016s on the lot so I couldn't compare.
I'll check in to advise.
