2024 Toyota Grand Highlander

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.

Subject: NHTSA Complaint - 2024 Grand Highlander Hybrid XLE Rear Windshield Shattering To Whom It May Concern, I am writing to formally file a complaint regarding a concerning incident with my recently purchased 2024 Grand Highlander Hybrid XLE. On [XXX], 2024, the rear windshield/liftgate glass spontaneously shattered without any apparent cause. The vehicle was merely six months old at the time of the incident. This unexpected and potentially hazardous occurrence has prompted me to investigate further, and I have come across multiple reports online from other customers who have experienced similar issues with the same rear windshield/liftgate glass on this specific vehicle model. This pattern of incidents raises significant concerns about a potential manufacturer's defect that may compromise the safety and reliability of these vehicles. Given the frequency of such occurrences and the potential safety implications involved, I am urging the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly. It is imperative to identify any underlying issues or defects that may be contributing to these incidents to ensure the safety of consumers and prevent any potential accidents or injuries in the future. Please consider this complaint as an urgent matter, and I implore the NHTSA to take appropriate action to address this issue promptly. Your attention to this matter is greatly appreciated, and I look forward to a swift and comprehensive investigation into this concerning issue. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Sometimes the radio lose volume all the way. You could turn the volume all the way up , change stations, FM, Sirius and nothing happens. The only way that this issue goes away and you can go back and start listening is to turn off completely the vehicle, leave if off, for a few secs, then power on . turn on the vehicle. This is very annoying since if you are driving for a long period of time, you cannot turn off the vehicle to do this trick. I hope this 3.0 Toyota Multimedia works better and more reliable.

When driving under 40 mph mainly the vehicle has extreme ear pressure. Sometimes you can hear a rumbling noise along with the ear pressure. The ear pressure is so intense that I can no longer drive or ride in the vehicle. It is an extreme danger because I get headache, nausea and dizziness along with the ear pain, which could lead to an automobile crash. There was not a problem with my ears prior to driving this vehicle, I have had no issues in the past in any other vehicle with ear pressure or pain and it only happens in this vehicle.

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.
