I'm a long-time Toyota fan and multiple vehicle owner. I'm writing because I'm disappointed with the inflated fuel economy that my new 2016 Toyota Tacoma Sport 4x4 is showing on the Eco display. At first I was extremely happy to see that according to the display I was getting 25-26 MPG. EPA ratings are 18/23. But then I measured it myself. Over the course of 4 tanks my actual was consistently between 20 and 21. This was not measured until about 4,000 miles and approaching 5,000 miles on the vehicle, so it wasn't just a first tank fluke. Having my Toyota reporting MPG that is inflated 20-30% over actual is disconcerting. Integrity, honesty and credible MPG calculations are important to me and what I expect of the Toyota brand quality. I am asking Toyota to please fix this --- for my vehicle -- and make sure that it is true and believable for all Toyota vehicles where it is reported.
So far Toyota's response has been frustrating --- I have written emails, followed through on their requests to go in to the local dealer to have it checked out multiple times, and many phone calls.
The local dealership's service department looked it over and did a ‘reset’ of the computer’s mileage tracking and said maybe this would fix it -- and to use it and then check it again. I did this and am experiencing the same issue. It is still not working properly.
Results are basically the same as before as I measure the miles per gallon (MPG):
18.535 gal 391.8 miles, 21.14 MPG
15.392 gal 320.1 miles, 20.80 MPG
Yet the truck’s Eco display shows a reading for this similar time period of 25.2 MPG.
I emailed Toyota and received a generic non-helpful email reply, so I called. Per Toyota's instructions I then went back in to a local dealer again -- this time for them to complete a Fuel Consumption Test they requested. They concluded:
“Vehicle MPG does not drop when vehicle is not moving. Gauge only factors in fuel used while moving not while sitting still."
The vehicle’s MPG calculation is incorrect and very misleading.
• The MPG calculation should be taking the total miles traveled divided by the number of gallons of gas used --- regardless of whether the vehicle is moving or not.
• This is a very common standard and general practice calculation known and applied by many, including the car industry the U.S. government and general consumers.
• Per the U.S. government’s fueleconomy.gov website (U.S. Dept. of Energy) on the page “How to calculate Your MPGâ€:
“Dividing the number of miles driven by the number of gallons it took to fill the tank. The result is the vehicle's MPG for that driving period."
• My MPG is being inflated by this erroneous MPG calculation
This MPG calculation needs to be fixed on my vehicle, and on all Toyota vehicles where a similar calculation and reporting occurs. Among my concerns are:
• That I can no longer use this feature to reliably track my MPG or monitor my vehicle’s condition as I should be able to do
• When I bought my vehicle, I selected and paid for many features that I value so that I could benefit from them
• This error in the truck’s MPG calculation is deceptive; it misleads me, and likely many others, to think that the Toyota Tacoma product is getting significantly better MPG than it really gets
• The value of my vehicle is significantly reduced due to this deceptive and misleading error, and more reduced to the extent that the product brand becomes associated with reduced quality, deception and/or being misleading
• This error takes away from the integrity, honesty and credibility I have come to expect as a fan of Toyota vehicles
Toyota - Please fix this problem right away --- for my vehicle -- and make sure that it is true and believable for all Toyota vehicles where it is reported.
I am feeling that I need this escalated to get it resolved as so far no one has been able to fix it. I have followed Toyota’s instructions to help you diagnose and fix this error, yet it still persists. I am getting impatient and do not want to be run through any more time-consuming hoops or activities. I am asking Toyota to please let me know the next step to get this resolved right away.
