 I bought a 2014 Infiniti QX60 Hybrid two months ago in March 2014.I immediately noticed that I am getting a combined 15 mpg on the trip computer (not the 25/28 mpg as advertised).After having the Infiniti dealer (Infiniti Manhasset) tell me there is nothing they can do, I reached out to Infiniti USA.They asked that I do a manual calculation by tracking how many miles I have driven on the odometer and how many gallons of gas it takes to fill up from the last fill up.After going through this exercise, the calculation was still right around 15 mpg (15.4 mpg to be exact).Infiniti USA told me yesterday that there is nothing they can do to help me .Is anyone else having this problem?
