The vehicle ev does not engage when it is cold outside for at least 10-15 minutes of driving. This drastically alters the fuel economy.

Highlander

  • 1,250 miles
The dte indicator on the vehicle is operating incorrectly. I filled the Highlander up with 10 miles dte and it only took 13.2 gallons of fuel. The dte indicator was 425 miles after fill up. Toyota advertises 600 miles per tank. My Highlander is 175 miles off of the manufactures advertised expectation. I don't know if I am out of fuel at 0 dte or if I can drive another 175 miles before empty. I averaged 35.6 mpg on this fill up but every time I fill the tank I get similar results.

Highlander

  • 2,000 miles
My 2021 Highlander hybrid platinum is experiencing a fuel filling issue. Over the first 2,000 miles, the vehicle will not take more than 13.5 gallons at fill up ' no topping off. The car has a 17.1 gallon tank. The car has gone as low as 2 miles to empty according to the car estimate. At each fill up it takes between 12.5 and 13.5 gallons. It is not clear if the tank is filling up completely and there are 4-5 gallons left at 'empty' or the tank is not able to fill completely. I purchased this car for it's fuel economy and range while traveling with my family. It is important to know if the tank is actually empty or still has substantial amount of fuel remaining so my family is not stranded out of fuel.
