SUSPENSION, ENGINE, SERVICE BRAKES
When making a left or right turn in this vehicle, there is a distinct knocking or clicking sound coming from under the drivers foot area. Dealer reviewed CV axel and suspension and says everything looks fine. However, I have driven enough cars to know that a persistent knocking sound while turning is not normal. This appears to be an issue with multiple 2024 Grand Highlander owners.

I was traveling on HWY 70 in Colorado outside Frisco at 65 mph temp about 35 degrees on 4/4/2025 when I heard a loud explosion. I pulled over and identified that the panoramic sunroof glass had exploded outward. There was no way a projectile could have hit the glass as a cargo carrier was on the roof rack completely covering the glass. The glass had an upward projection as well. I have included photos. The dealer refuses to take responsibility for the poor construction of the sunroof glass.

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
Intermittently, my vehicle will hesitate to accelerate or will move only marginally (disproportionately to the depressing of the gas pedal) from a complete stop. When it occurs, it often does so for a number of seconds. This has been incredibly dangerous given I live off a busy street and I cannot trust that when I press the gas pedal to accelerate to turn onto the street, that my vehicle will be caught in oncoming traffic and hit.

POWER TRAIN
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.

POWER TRAIN, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

FUEL/PROPULSION SYSTEM
Fuel fill-ups averaging 13-14 gallons when vehicle trip computer alerts 0 miles remaining distance to empty. Fuel tank capacity published as 17.8 gallons. Total vehicle range understated, requiring more frequent stops at gas stations to fill. Not a direct safety concern, but a significant nuisance and dealer has stated this is normal and there is no fix for this issue. EPA estimated MPG 26-27, should equate to approximately 460+ miles/tank. Instead experiencing approximately 350-365 miles per full tank of fuel.

VISIBILITY/WIPER
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.

FUEL/PROPULSION SYSTEM
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

FUEL/PROPULSION SYSTEM
Since we purchased the 2024 Grand Highlander Hybrid Limited in April 2024, there has been an issue filling the fuel tank completely when the vehicle is on empty. The stated fuel tank capacity from the owner’s manual is 17.8 gal, however the maximum amount of fuel that can be pumped into the tank using auto fill at the gas station is 12 gal before the pump “kicks off”. After this, the fuel gauge on the dash reads full, however fuel range shown is 330 mi (at 30 mpg average gas mileage) when it should be closer to 500 mi with specified fuel tank capacity of 17 gal and 30 mpg. Shortly after filling the fuel tank, the fuel gauge and range will quickly decrease while driving. From researching and reading dozens of online forums about this issue, I tested filling the tank manually at the pump, extremely slowly, not using the auto fill lever. Two times doing this test, I was able to pump 14.5 gal into the tank before the pump “kicked off”. After these fill ups, the fuel gauge showed full and did not quickly decrease when driving. Also, the range now showed 450+ mi remaining. Both times after what appears to be an actual full tank fill up, the vehicle recorded over 400 miles before the fuel low light turned on, while previous max miles was in 300 range. It seems as if the fuel tank design does not allow the fuel to enter and settle in the tank quickly enough when filling, causing the pump to “kick off” prematurely and not actually fill up the tank. This issue causes the vehicle to not reach the full mileage range with advertised MPG and tank capacity, causing more frequent and inconvenient trips to the gas station. We have taken the vehicle to a Toyota Service center and they documented the issue but were told by Toyota Corporate that they do not have a fix for it at this time. Tech Tip T-TT-0742-23 exists on NHTSA.GOV website related to this issue from November 2023.

FUEL/PROPULSION SYSTEM
This vehicle is supposed to have a 17.8 gallon tank but each time at fill up when the vehicle is on empty you can only put about 13.5 to 14 gallon of gas in the tank. Several owners are experiencing the same issues. Toyota Dealerships are aware and no action is being taken to resolve this issue. The mileage to empty is not aligning with the amount per gallon as advertised per TOYOTA manufacturer.
