2020 toyota highlander hybrid awd. When filling from almost empty (per low fuel warning light and distance to empty reading almost 0), tank only accepts ~12.5 gallons before gas station fuel nozzle auto clicks off. The fuel gage at this point indicates that the vehicle is ~7/8 filled. The owners manual warns about not attempting to fill after the fuel nozzle automatically clicks off. Being unable to fill tank may lead to owners attempting to overfill tanks and could result in inadvertently spilling fuel which poses a safety risk and an environmental damage risk. It can also lead to more emissions. A similar problem exists with 2019/2020 toyota rav4 per the federal safety agency records, toyota has proposed a fix for this vehicle but has stated that no other models are affected by this issue. The problem described above is almost identical with the exception that the vehicles have different fuel tank capacities. Toyota has indicated that this is "normal".
2020 Toyota Highlander fuel system complaints
Page 2 of 2: complaints 11 to 20 of 20, newest first, as owners wrote them.
When re-fueling the vehicle with dte of less than 30 miles, the fuel shuts off around 12 gal. 2nd click for fuel stoppage may yield another 0.5 gal. Nothing adds up to 17.1 gal of fuel in the tank. Going beyond the 1st click is bad for the system, yet only fills the car up to 7/8 full on the fuel gauge.
Fuel gauge does not properly register full hybrid fuel tank (design) and/or defective fuel level sending unit. Toyota service report (6032680/1- 25 sep 2020); toyota service report (6046594/1- 21 jan 2021).
2020 toyota highlander hybrid platinum awd cannot fill up fuel tank all the way. Max can fill it up when it shows 0 miles left of fuel is less than 13 gallon and car has over 17 gallons. Toyota is saying they don't know what the issue is. No solution at this time for a $50k car
The fuel tank capacity listed as 17.1 gallons but only take between 12-12.5 gallon when filled up, even when the reserve has ran down where mile to empty is near zero. Total miles range between fill ups is under 500 miles, far less than the 616 miles range claimed by toyota.

The gas tanks holds 17 gallons or ~570 miles to empty. The most I can fill it is ~14 gallons or ~470 miles to empty. It always clicks off like it's full. I've tried gently topping off, slightly pulling out fuel model etc. Nothing has worked. This has happened since the vehicle was new and driven off the lot. This is all while the vehicle is parked at a gas pump.
I purchased a 2020 toyota highlander hybrid awd in may 2020. In june 2020, I noticed a discrepancy between the gas gauge ABS the distance to empty indicator. The gas gauge said there was 3/4 of a tank left but the dte said I had only 43 miles. I went to the gas station today (october 2020) to fill up my vehicle and filled it until the gas shut-off tripped. I turned on my car and noticed that my gas gauge said it was only 7/8th full. Thinking it tripped too soon I refilled it again but only 0.5 gallons went into tank before the shut-off tripped again. When I turned on the car this time the gas gauge indicated it was full. I doubt the gas gauge is functioning properly.
My new 2020 highlander hybrid has a big issue with the gas tank. I get only 460 miles, even if I top it off with the gas spewing out. Toyota advertised a 600 mile range to the highlander hybrid. The 600 mile fuel range seems very off with the 2020 highlander hybrid. I have the xle and always have kept it in eco mode. I've driven over a thousand miles on the car, but the mile range estimate on the car is inaccurate and seems to be off a lot if it's supposed to get 600 miles to a tank. More importantly, when the tank is empty (the dash says I had 5 miles left to empty), the gas tank only holds around 13 gallons even though the fuel tank capacity is supposedly 17.1 gallons. Those 4 gallons make for 140 miles less distance on a tank. If I wait and keep on forcing the gas in slowly, I can get 15 gallons but I don't like the idea of having to keep on pushing the gas nozzle until the gas spews out of the tank just to get 15 gallons in. I know toyota has been having gas tank issues in other models recently. One of the main reasons I bought the car was for the fuel tank capacity and range. A video explanation of the problem is below: https://www.youtube.com/watch?v=huu649zrl-g&t=245s.
Toyota advertises and represents that the highlander hybrid′s fuel tank capacity is 17.1 gallons, and based on its 35 mpg rating, the range should be about 600 miles. However, I am not able to fill the tank by more than 12 gallons thus reducing my range to 420 miles. I believe there is a defect in the newly designed saddle tank which prohibits the tank from being filled completely thus cheating me out of about 180 miles of driving range.
