2024 Toyota Grand Highlander fuel system problems

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.

The contact owns a 2024 Toyota Grand Highlander. The contact was unable to fill the fuel tank completely. The contact stated that the fuel tank had a 17-gallon capacity; however, the contact was only able to get more than 10 gallons into the tank. Additionally, the contact stated that the Auto START/STOP feature was not functioning as needed. The contact had taken the vehicle to a local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired.
