2024 TOYOTA GRAND HIGHLANDER Complaints

My car makes a click sound when turning the wheel left or right and gas is applied. This has been happening for around 5 months. It’s not noted all the time but I do hear it occasionally. I have a DashCam video with sound as proof, but this website is not letting me upload the video as its file size is too big. I have taken to the dealership to inspect but they said they were not able to reproduce the sound while inspecting. They also mentioned Grand Highlander have some sort of front axle issue. I looked online and NHTSA website and found that Toyota is aware of this issue and resigned it. But i don’t think the issue is fixed yet, something is still wrong with it. Please look into this matter as it concerns the safety of my family and others who owns the car.

While slowing to a stop on a slight incline (an interstate off-ramp), when almost stopped, the car started bucking as if the brake pedal was being slammed on, then released, slammed on again, then released, and repeated for maybe 2 seconds. I quickly hit the "P" (Park) button to take it out of gear and it stopped. No warning lights or anything came on and it drove perfectly fine afterwards. It felt just like the emergency braking and the car thinks you're going to hit something. It was very strong and jarring. Happened a 2nd time on April 4 in the same circumstances - driving downhill on a highway off-ramp and stopping at red light at the end of the ramp.

The contact then turned off the vehicle shifted the vehicle into reverse and the vehicle started working properly. On a separate occasion, the contact depressed the brake pedal and the vehicle failed to respond. The local dealer was contacted; however, the vehicle was not repaired because the VIN was not under recall. The manufacturer was made aware of the failure. The failure mileage was approximately 22,554.

While driving, my panoramic moonroof exploded. There were no rocks or big vehicles on the road, but the panoramic moonroof simply just exploded. This could've been very dangerous and could've caused serious injuries for those inside of the vehicle, especially if the vehicle was moving.

After driving over 15k miles in approximately one year, my 2024 Toyota Grand Highlander Hybrid fuel tank has never been filled with more than 12 gallons of gas, even when the Low Fuel light is on and the miles to empty are less than 10. The MPG for individual trips can be as low as 10.3 MPG; the overall average MPG has been 21 MPG or less. The advertised fuel tank size is 17 gallons and the MPG is 26/27. The Toyota dealership said that there are 3-5 gallons remaining in the tank when there are as few as 5 miles to empty. Actual miles to a tank are around 280-300 when driven in Eco mode; advertised is 450 miles when driven normally. Inaccurate fuel level sensing is a safety issue. 10.3 MPG for a Hybrid that is advertised to get 27 MPG is false advertising. This is a known issue since at least November 2023, as evidenced by the Manufacturer Communication Tech Tip T-TT-0742-23 on NHTSA.GOV.

At 2300 miles we got hybrid malfunction on the dashboard, we called Toyota and had the car towed to the dealer. Based on what dealer mentioned and showed picture - there were fragments in 2 cylinders and the 3rd cylinder basically dis-integrated.

Cv axle has been replaced twice so far on my 2024 grand Highlander and it’s only at 18,000 miles currently. From the TSB Toyota put out they redesigned in the middle of production but those who were before this time will always have cv axle problems

When making left or right turns loud knocking noise is heard until turn is completed and going straight.
