2021 Toyota Highlander Fuel system Problems

“Gas tank only holds 12.5 - 13 gallons with a range of 425-450 at most whereas Toyota claims in their advertising and specs that the tank hold 17.1 gallons and the car has a range of 598 miles. I confirmed with Toyota that this is off specification and they said the tank will only take 14 gallons and the range will decide itself. I use the car for long trips, bought it for the tank size and range and am concerned I am going to run out.”

“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.”

“I reported my gas tank not filling past 12.9 gallons of gasoline on numerous fill ups on my new 2021 Highlander hybrid platinum to Toyota service department. The Highlander on invoice says it's a 17 gallon tank capacity. Toyota service depart refilled my empty tank to12.6 gallons verifying my complaint. The service advisor informed me they notified Toyota and Toyota responded in saying they are aware of the issue and there's nothing todo. The Toyota service advisor inform me until there is enough complaints then Toyota would issue a recall”

“This is not a safety issue per se but one of false advertising. Toyota advertises the range of my hybrid Highlander as 600 miles on 17.1 gal tank at 35 mpg. I do get 35 mpg (which is quite commendable for a vehicle this size) but I cannot fill the fuel tank more than 12-13 gal even when nearly bone-dry empty. In turn I cannot drive any further than 450 miles without filling up. Something is wrong with either the design of fuel tank such that not all the fuel can be accessed or the design of the fuel filler hose such that one cannot fill the tank completely. …”

“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. …”
