Sometimes the vehicle will be very sluggish when accelerating from a stop, it is hard to replicate, and inconsistent.

while the engine has not warmed up, when its hot and air conditioning is on high, vehicle does not respond to the gas pedal while trying to accelerate from a stop. vehicle hesitates on acceleration. i feel this is a safety problem, because i need the car to merge quickly onto the road from a stop. this hesitation could cause a bad accident. i feel like the hesitation, is the car trying to find the gear.

When accelerating from a stop, there is a hesitation or lack of power when stepping on the accelerator. Releasing the accelerator and depressing it again will get the car going. The engine also revs high at low speeds before dropping to the next gear.

Starting off from a stop or at low speeds the vehicle loses all power. Engine stumbles and does not respond, when it happens it almost feels like the engine may stall. Pressing the accelerator and the vehicle will not move, then suddenly will start to go seconds later. This has almost resulted in a crash since the vehicle loses all propulsion unexpectedly. No warning lights. Took to the dealer twice and everything is -??normal-?? no codes stored.

The fuel tank capacity according to the vehicle specifications should be 17gallons. I have refilled the vehicle three times after reaching empty (around 20mi left according to the gauge), and when I fill the tank it only takes about 11 gallons to fill. That is a significant difference. Even with a reserve, I should be putting around 15 gallons in the tank when it is on empty to fill it. I am concerned that the tank is not the correct size or there is a problem with the fuel level sensor.

Toyota is having issues filling up the tank as the specs says (Owners manual book). According to the Owners manual book, the Gas tank of these vehicles are 17.2 Gallons and 2.6 of those are saved for the reserved. In theory, we should have 14.6 Gallons to fill-up as soon as we see the "Empty sign" on the vehicles. Now, the thing is that even after this happens, we can only fill-out up to 11.5 gallons. I have tried several times, saving the history on FUELLY, and its always the same. I have asked the dealership and they don't know what to do. If you just search for "Grand highlander gas tank issues" you will find thousands of people that have the Grand Highlander (not only the Hybrid, models, but all models) are saying the same thing (Facebook groups you can join and talk with real people who can prove you this issue) the gas tank cannot be filled up to what the size of the tank is (owners manual) This is not good since we dont know the real value of miles / gallons of tank left so we know when we could fill up the tank specially if you are on a long road trip where there are not a lot of gas stations between places. Please ask TOYOTA to find where the issue is in here, it might be just the air is not allowing the gas pumps to fill out more gas in the tank.

Myself and all Grand Highlander owners of the new version that just came out in 2024, we have the same fuel issue. The car is only registering half a tank of gas. If you go to the grand Highlander forum every driver is reporting the exact same issue over the last three months that the car has been out Toyota has put out a statement but has no solution, it is a hybrid and it-??s supposed to get 400 miles or more per tank and we have to fill it up every time we drive only 170 miles. However, when the tank says on the digital screen that it is empty, there is still 10 gallons in the tank. This is for all owners and effects all cars of the Grand Highlander Platinum Max only.
