2024 Toyota Grand Highlander Other Problems

While your friend was driving your 2024 Toyota Grand Highlander on the New Jersey Turnpike, the vehicle suddenly lost speed and then caught fire while moving. The fire spread rapidly, completely destroying the vehicle within 5-10 minutes, creating a serious safety hazard. Your car had been recently serviced with no warning signs beforehand. This requires immediate investigation to determine the cause of the unexpected fire.

Description of Issue: We have experienced multiple episodes of violent shaking in our 2024 Toyota Grand Highlander while stopped at red lights or in intersections. Both my wife and I have had this happen independently, around two to three times each. Most incidents occurred while our young children were in the vehicle.

Your car sometimes refuses to accelerate when you press the gas pedal after stopping at a light or stop sign, leaving you stuck idling or stranded in traffic. The lights and other systems work normally, and the problem occurs whether the AC is on or off. The engine seems to jerk but won't move forward. This issue happens intermittently and may require diagnosis of the transmission, fuel delivery system, or engine control computer to identify why acceleration is being blocked.

Your vehicle hesitates or fails to accelerate for 1-5 seconds after you press the gas pedal when starting from a stop, particularly on slight inclines. This unresponsive acceleration occasionally happens multiple times during short drives and creates a safety concern when merging or turning into traffic. The issue may involve the fuel system, engine management, or hybrid transmission components that need diagnostic testing and possible reprogramming or replacement.

Your vehicle has a large hole in the undercarriage that runs from the back to the front of the vehicle. The hole is large enough that a child could potentially enter the vehicle's underside without being noticed, which could be extremely dangerous if the car is in motion. This appears to be a manufacturing or structural defect that requires immediate inspection and repair to close the gap and ensure passenger safety.

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.

Your dashboard is displaying warning messages indicating that your front sensors aren't working properly. The dealership identified that your right front ultrasonic sensor needs replacement, which they said may have been damaged by small rocks or debris during normal driving. Toyota declined to cover the $823.81 sensor replacement under warranty, and disabling the sensor to clear the warning messages also turns off some of your vehicle's safety features like obstacle and pedestrian detection. The repair will involve replacing the ultrasonic sensor and reprogramming the vehicle's safety system.

Your vehicle's air conditioning condenser is fully exposed behind the front grille with no protective cover, making it vulnerable to damage from road debris like rocks. You may experience condenser damage even from small impacts, and Toyota has declined to cover repair costs under warranty. The fix would likely involve installing a protective condenser guard or cover to shield it from road hazards.

Your vehicle is stalling and hesitating when accelerating from a complete stop, and it's also decelerating unexpectedly when you're trying to merge onto the freeway—dropping from 65 mph down to 30 mph, which creates a safety risk. The problem started around 8,500 miles and happens consistently in these situations, though your dealer hasn't been able to reproduce it or find any diagnostic trouble codes. The shop foreman suspects a fuel pump issue may be causing the engine to not receive adequate fuel during acceleration.

While driving at 65 mph in cold weather (35°F), your panoramic sunroof glass suddenly exploded outward with no external impact — a cargo carrier on the roof rack was covering it completely. The glass shattered with an upward projection, suggesting an internal failure rather than external damage. The dealer has declined to cover this under warranty, citing poor construction as the issue. Repair will likely require full sunroof glass replacement and inspection of the sunroof frame and seals.

After you turn off your engine, you notice a strong gasoline smell coming from your vehicle, and this happens repeatedly. The dealer performed several tests but couldn't identify or fix the problem. Because of the smell, you're unable to safely park the vehicle in your garage. The issue may involve the fuel system, fuel injectors, or related seals and connections that need inspection or replacement.

Your front CV joints and axles are failing prematurely — both sides needed replacement at just 15,000 miles despite only highway driving. You may hear a popping or grinding noise when turning and accelerating, and multiple owners report this problem recurs even after being repaired. The fix will involve replacing the CV joints and axles on both front sides of your vehicle.

Your vehicle sometimes doesn't respond when you shift gears—such as from Park to Reverse or Drive—even when you press the gas pedal. The car may not move until you wait a moment and try again, or you shift back to Park and select the gear again. This issue has occurred intermittently since you bought the vehicle over a year ago, with no predictable pattern. The dealer was unable to identify a cause. A transmission control module diagnostic and potential transmission fluid service or solenoid replacement may be needed to resolve this shifting delay.

When you come to a stop at an intersection, your vehicle won't accelerate normally and experiences a severe loss of power, only slowly moving forward for 10-15 seconds. This problem happens most often in hot weather when the air conditioning is on, creating a dangerous situation in traffic. The issue may involve your engine's ability to deliver proper power when the A/C compressor is working hard in heat.

Your rear glass shattered with almost no pressure applied to it, leaving you without a rear window for 8 weeks while waiting for repair. The glass appears to be unusually fragile, and other owners have reported the same problem occurring on their vehicles.

Your 2024 Grand Highlander has developed a knocking noise when turning left or right, which started before 500 miles. The dealership found and replaced a broken axle at 5,000 miles, but you still hear knocking when turning even after the repair. Additionally, your rear AC fan has malfunctioned and hasn't been fully fixed. A replacement axle and rear AC fan assembly may be needed, along with a thorough inspection of the steering and suspension components to identify why the knocking persists.

Your new Grand Highlander started making popping noises when you turn corners at around 1,000 miles. The dealer has replaced the axles twice, but the noise persists. You've been told the axles had a manufacturing defect and that your car isn't safe to drive until replacement axles arrive, which are currently on backorder.

Your car is making a clicking sound from under the steering wheel when turning from a stop, which started on the right and later began on the left, getting progressively louder. Toyota replaced both front axles under warranty, after which your car's steering felt noticeably tighter with better road feel and handling — suggesting the original axles may have been defective. The service manager couldn't explain the root cause but said the car was safe to drive, though the improved handling after replacement suggests there was a significant front-end issue.

Your center console display stopped working the day after you picked up your car and keeps rebooting every minute, which is distracting while driving. Because the display also shows your rear-view camera feed, the camera image is unreliable due to these constant reboots. The issue started occurring immediately after purchase on December 16, 2023. This will likely require diagnosis and repair or replacement of the display unit and its electrical connections.

You bought a 2024 Toyota Grand Highlander in Canada and plan to drive it in the United States, but Toyota won't confirm the vehicle meets U.S. federal safety standards beyond its labeling. Your vehicle has a tire pressure monitoring system (TPMS), but Toyota's documentation doesn't list it as installed, which concerns you about safety on U.S. roads. You're asking for verification that your vehicle is safe and compliant to drive in the United States. This may require Toyota to provide official documentation confirming U.S. safety compliance or to inspect and verify the TPMS system is present and functional.

Your car occasionally smells like gasoline on the right side of the vehicle, both near the driver's side and in the right rear passenger area. The smell occurs intermittently when the engine is running and after you turn it off, even when you're not topping off the fuel tank. A mechanic should inspect the fuel system for leaks or loose connections on the right side of the vehicle.

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.

Your front axles make a clicking sound when you turn the steering wheel. This is typically caused by worn or damaged CV joints, which are components that allow your wheels to turn smoothly while maintaining power from the engine. A mechanic can inspect the CV joints and boots for wear and replace them if needed.

Your center display screen keeps showing a blue enrollment advertisement for a paid Driving Experience service that blocks access to your normal driving instructions. This pop-up appears repeatedly and is distracting while you're driving, and the dealership says there's no way to disable it. The issue may require a software update or display system repair to remove the unwanted advertisement.

Your vehicle makes a consistent low rumbling noise when driving at speeds between 15-20 mph. This noise occurs regularly and may indicate an issue with the suspension, exhaust system, or drivetrain components. A mechanic will need to inspect the undercarriage and exhaust system to identify the source and determine what repair is needed.

Your car has a constant pressure buildup in the cabin that you feel especially in your ears, particularly when driving slowly on bumpy roads with all windows and sunroof closed. The problem is worst between 10-30 mph, and after a 45-minute drive your ears hurt and you hear humming that lasts for hours afterward. You noticed this issue the day after purchase (March 2, 2024), and the dealer's suggestion to turn off recirculation and open the vents didn't help. The fix may involve inspecting and adjusting the cabin air pressure system, ventilation seals, or audio dampening materials.

Your cabin feels pressurized, causing your ears to pop and creating an odd sensation similar to being on an airplane. You notice a strong pulsing pressure that occurs around 45 mph on smooth roads, and low-tone pressure sensations when going over bumps at slower speeds — similar to wind buffeting that normally happens when one window is down, except no windows are open in your case. Opening the windows doesn't help. The issue may involve the vehicle's ventilation or cabin pressure regulation system needing adjustment or inspection.

You're experiencing a persistent sensation of ear fullness and disorientation while driving your 2024 Grand Highlander, similar to being at high elevation or on an airplane. The problem occurs regardless of speed or whether the windows are down, and it makes you feel unwell while driving your family. This may be related to cabin pressure or ventilation issues, and a Toyota dealer inspection is needed to diagnose the cause.

Your side mirror vibrates excessively when the music system is off, and vibrates even more noticeably when music is playing—almost like it's shaking in rhythm with the music. This suggests a loose mirror mounting or a resonance issue that gets worse with audio frequencies. The fix will likely involve tightening or adjusting the mirror bracket and mounting hardware.

“Apple CarPlay Escape” is not available through software update for this vehicle although other cars of the same model year and 2025 models have this option to quickly navigate between Apple CarPlay screen and Toyota settings screen. As a result, More swipes/touches are needed on the screen to navigate which is unsafe and distracting while driving

I was heading home with my 6 year old son when all of a sudden there was a loud boom. Initially I thought there was an explosion or gun shot but then realized the panoramic moonroof had shattered and I continued hearing shattering. I pulled over the car to make sure I could creat some sort of safety for my son.

At speeds under 30 MPH cabin air pressure builds in the cabin and creates a bass sound or “cabin boom”. The pressure hurts occupant ears as well and has made them sick after riding in the vehicle. This is a well known issue with the Grand Highlander.

Your car makes a low-pitched booming noise when driving above 40 mph, similar to the sound of a partially open window, even though all windows are closed. The noise gets louder as you accelerate to higher speeds like 70-80 mph. This issue, sometimes called "cabin boom," may require inspection of your vehicle's sealing, weatherstripping, or acoustic panels to identify and eliminate the source of the noise.

Issue started as soon as we first received the vehicle. Speeds 0-35 on almost any road causes a low frequency rumble until around 40mph. The sensation is very painful to hear and at times its nauseating.
