Seven problems related to other fuel system tank assembly have been reported for the 2021 Toyota Highlander. The most recently reported issues are listed below.
Highlander has same issue as the 2019-2020 Toyota rav4 fuel issue identified by the NHTSA: vehicle fuel gauges displaying less than full and/or total fuel dispensed is less than expected, when the fuel nozzle automatically clicks off. Noted the �distance to empty� shown on the multi-information display is less than expected. While driving, vehicle abruptly comes close to shutting off because gauges are inaccurate. Vehicle cannot be driven to the full capacity of the stated range. Gas tank is 17. 1 gallons but vehicle cannot take more than 12-13 gallons from empty.
I bought my 2021 Toyota Highlander xle awd from Toyota of dallas on 4/11/21. I have had nothing but trouble from the fuel guage / distance to empty system. From showing full when the tank is not full to refusing to change from full even after driving over 100 miles, I have become very disturbed by this vehicle. I am unable to get Toyota and the dealership to respond to me after several attempts. My car is currently sitting in the garage showing a full tank after driving 169 miles after refuelling! what in the world is going on? someone please kindly help. Josh. 4695783279.
Toyota manual spec and website advertise the tank capacity is 17. 1 gallons. However, I can only fill top off around 12. 5-13 gallons which misleads to customers. The problem is that I don't know whether the gauge is incorrect (showing full too early) or the tank is out of shape which I can't fill to 17. 1 gallons. This can cause unwanted situation where people think they can go couple extra hundred miles before it goes empty or people continue forcing to pump more gas after 12. 5 gallons due to 17. 1 gallons capacity. The Toyota app also gives the range around 420 miles which is an estimate for mpg of tank capacity around 12 gallons. It is hard to know whether my car got issue or company faulty advertises the tank capacity (long range per fill) to attract customers. I would love to know what's going on so I can use it properly.
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 2021 Highlander hybrid is not taking more than 10-11gallons per fill up and the distance to empty indicator only states approx. 420miles not the 590-615miles based on the stated 34/35 mpg per Toyota on the hybrid model. We have filled the vehicle several times and at multiple gas stations and each time the tank will not accept more than 10-11gallons.
Can not fill in a full tank of gas. At most the car takes 13 gallons, where as the tank capacity is 17, which is 4 gallons shorter and gives 140 miles shorter range (calc according to epa rating). 140 miles is a huge difference. Even if you fill more than 13 gallons, the range stays at 423 miles and doesn`t increase.
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.
