2024 TOYOTA GRAND HIGHLANDER Complaints

Rear glass seemed to shatter very easily. Almost no pressure caused this to happen. Caused an 8 week period with no glass. Repair has occurred. Others reporting same issue.

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.

The vehicle is consistently making a low rumbling noise at 15-20 miles per hour.

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.

The contact owns a 2024 Toyota Grand Highlander Hybrid. The contact stated the vehicle failed to maintain proper fuel pressure. The contact stated that while refueling the vehicle, the pump would click off before the vehicle was fully refueled. The vehicle was taken to a local dealer but no cause for the failure was found. The manufacturer was not made aware of the failure. The failure mileage was approximately 300.

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.

I purchased a limited grand Highlander in October. With less than 500 miles I had a knocking noise when turning right and left. I took it into the dealership they were unable to find anything. However, after 5000 miles they found my axle was broken and replaced one. They had my car 29 days as part was in back order and I refused to drive it due to safety concerns. My AC fan in the back was also broken and has been repaired. I still hear knocking when turning however and the fan is still broken. filed the lemon law. I also saw a complaints about the vibrating part of the car which my hood also does. I feel like they should have a recall as there are many forums with broken axles.

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.

the problem is the constant pressure felt in the cabin especially most at the driver side. the pressure is felt by my ears persistently when all windows, sunroof are closed. it's the worst when driving slowly (between 10 to 30 mph), any uneven road bumps magnify to constant "cabin boom". After a long (45 minutes) commute to work on local roads, my ears are hurt, humming persist for few hours. The dealer checked and suggested to open the vent to allow fresh air in cabin (turn off recirculating air button), but it didn't help. I felt this pressure problem the next day I bought it (on March 2, 2024) when drove to work. this could have been when I test drove it, but it was a short drive, I didn't notice. I test drove the other gas Grand Highlander, AWD, Limited trim on the dealer slot. it had the same problem. Dealer said they don't have fix for this while it's hurting my ears every cummute to work. the car mileage now is only around 500 miles.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that while his wife was in reverse at 10 MPH, she collided with another vehicle. Though equipped, the back-over prevention system failed to activate, which could have potentially prevented and/or lessened the collision. The air bags did not deploy. No warning lights were illuminated. A police report was not filed, and no injuries were reported. The vehicle was taken to an independent mechanic, who was unable to duplicate the failure and informed the contact that the incident recorder does not log data for incidents under 25 MPH. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 500.
