2024 TOYOTA GRAND HIGHLANDER

AIR BAGS:SIDE/WINDOW:CURTAIN

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2024 Toyota Grand Highlander, Grand Highlander Hybrid, Lexus TX350, TX500 Hybrid, and TX550 Hybrid+ vehicles. The driver and passenger side curtain air bags may not unroll as intended and could partially deploy outside of an open window. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 226, "Ejection Mitigation."

Risk: An improper deployment of the side curtain air bag can reduce occupant protection during a crash, increasing the risk of injury.

Toyota T-SB-0082-24 / Rotational Clicking Noise From Front Drive Shaft Assembly ( CV JOINT) CV joint defect poses an unreasonable risk to safety, especially if it fails while you are driving. An unreasonable risk is one where the potential for harm is much greater than the potential benefit of taking the risk. Driving with a compromised CV joint fits this definition because it can lead to a complete loss of vehicle control, which can result in a serious accident.

ENGINE

Description of Issue: I have experienced repeated incidents where the accelerator pedal becomes unresponsive (“dead pedal”) after coming to a stop. When pressing the pedal to accelerate, the vehicle does not respond at all for several seconds. Then, without warning, it suddenly surges forward with excessive acceleration once the power engages. This problem happens intermittently throughout a drive each day, often enough to be concerning. It occurs after being stopped at an intersection or in traffic. No warning lights or error messages appear before or during the issue. The delay followed by a sudden surge is dangerous, as I expect the car to move when I press the pedal, but it hesitates instead. When the vehicle finally responds, it accelerates quickly, which could cause me to lose control or collide with another vehicle. Safety Concern: This malfunction creates a significant safety risk. It puts myself, passengers, and other drivers in danger when the vehicle fails to accelerate as expected in high-risk scenarios such as crossing intersections, merging into traffic, or making left turns. The hesitation can leave the vehicle exposed in traffic, and the sudden lurch forward can cause unintended movement or rear-end collisions. Status: The problem has occurred multiple times under similar conditions and is ongoing. It has not yet been inspected or confirmed by a dealer or service center, but I have an apt Aug 24th. However, the malfunction is real, reproducible, and presents a serious hazard that could lead to an accident if not corrected. Many others with the same vehicle have expressed the same concern as well on forums and reported no fix after dealership appointments.

“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've had consistent issues with the vehicle accelerating and shifting. These include sluggish acceleration, loss of power, sputtering, and limp mode. We've almost been hit by other vehicles almost 10 times because the vehicle has failed to accelerate when pulling into a roadway. The vehicle will start to accelerate slowly, then stop, then 5-10 seconds later will surge forward will the engine revs very high and is delayed shifting into 2nd gear. I've told my Toyota dealership about this numerous times but they keep telling me that there's no issue but there clearly is being that many others are experiencing the same exact problems. There's never been a warning lamp or message when this happens. This is a huge safety issue and my family is extremely lucky that we haven't been involved in a serious accident.

AC condenser has a leak and AC cooling not working-blowing hot air, making vehicle very hot inside. Toyota claiming from road debris damage, front grill not protecting condenser unit enough to allow this not to happen and will not cover under warranty. Seems like a manufacturer grill design problem not consumer. Toyota has no fix to the problem to protect condenser unit from this happening over and over again.

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. The most recent incident occurred today, when my wife experienced it twice in a row while stopped at an intersection. Our children were not in the vehicle during today’s event. Component or system involved: UNKNOWN at this time. We suspect a major mechanical or drivetrain-related failure. The entire vehicle shakes violently and feels unstable. We are willing to make the vehicle available for inspection upon request. Safety risk: The severity of the shaking is extreme and it feels as though the car may explode or fall apart. We have had to put the car in park, shut it off immediately, and in some cases, exit the vehicle in the middle of intersections or while stopped at a red light. This places everyone in the vehicle at serious risk, especially our children, and could result in a crash or secondary accident due to the abrupt stop and unexpected behavior in active traffic. Has the problem been reproduced or confirmed by a dealer or service center? The issue has not yet been reproduced by the dealership. We brought the vehicle to Toyota of Escondido after a previous incident. They inspected it but stated they could not find anything wrong. Has the vehicle or component been inspected by others? The vehicle was only inspected by the dealership (Toyota of Escondido). It has not been reviewed by any other parties such as law enforcement or insurance representatives. Warning lamps, messages, or other symptoms prior to the issue: There were no warning lights, error messages, or abnormal behavior prior to the onset of the violent shaking. The issue occurred suddenly each time, without warning.

Sometimes,about 50/50 now, when I stop at a light or a stop sign then try to go, my car refuses to go. Pressing the gas won’t make it go. I just sit there idling or worse, in the middle of oncoming traffic. The lights still work, everything else seems to work. This does this with or without the ac in. It almost jerks you around, but won’t go. This has happened multiple times now.

ENGINE

It has a hard time shifting at times when the car has just been started

FUEL/PROPULSION SYSTEM

Ever since I got my car, sometimes it smells like gas on the right side of the vehicle. By driver side and right passenger side in the back. I assumed it was because I topped my gas off, but even when I stopped doing that, it still has a strong gas smell when the car is running and after turning it off. Not ever day, but ever so often.

Numerous times now the vehicle will not accelerate from a stop for about five seconds after the gas is pressed. It always seems to be on hot days with high air conditioner demand.

ELECTRICAL SYSTEM

Over 1.5 years of owning my new 2024 grand Highlander platinum hybrid pro max I have had multiple incidents (6 documented now with toyota) where after coming to a complete stop I go to accelerate and the car shutters,sputters,lunges, and even looses power or goes into “limp mode”. I have been almost hit several times now by oncoming traffic because my grand Highlander completely loses power. It will not accelerate. After 5 seconds I typically hear loud groaning noises followed by two loud bangs and two violent lurches forward before my car finally regains power. No warning lights popped up on my dash any of the times my car has lost power. My dealership keeps telling me “no problem found” and that I am the only one with this issue. This is false. There are many complaints online and finally after I did not give up the dealership pulled a comprehensive RoB scan/report on my car and found multiple transmission failure codes on the transmission system/TCM. One “lack of acceleration code” was even dated two weeks before I bought my brand new grand Highlander with toyota. I received my grand Highlander with 6 miles on it. I was the first owner. My PDI “pre-delivery inspection date was one week after this transmission failure code”. When I presented this to toyota reps who finally met with me at the dealership they had nothing to say. Toyota knows about this problem and they do not know how to fix it. It is a serious safety issue and I refuse to allow someone to get hurt because Toyota will not be honest and relay this known issue. After the dealership and toyota reps told me I was the only one with this issue toyota officially released a service bulletin in March 2025 for a TCM flash reset/update to address sluggish acceleration, loss of power, and limp mode with the transmissions TCM when the hybrid systems battery is at 33% or less. My dealership installed the TCM update about 1.5 months ago and unfortunately my car has had two more instances since with loss of power.

UNKNOWN OR OTHER

I was informed by my Toyota dealership and received a written letter from Toyota dated March 25, 2025, that the curtain airbag recall on my 2024 Toyota Grand Highlander had been completed. However, during a scheduled maintenance visit in June 2025, I was told the airbag recall had never actually been performed and was still open. The recall was only completed at that time. I unknowingly drove the vehicle — often with my infant child — for several months, believing the airbag system was safe, based on incorrect information from Toyota. This represents a serious safety concern and a breakdown in Toyota’s recall management. The issue has now been fixed, but I am reporting this because I was misled into driving an unsafe vehicle, putting my family at risk. Toyota’s failure to properly close and track recall repairs should be investigated.

The vehicle’s design leaves the condenser completely exposed, with no protective barrier in place. As a result, even a small rock can easily pass through the front grille and cause significant damage. That’s exactly what I’m currently experiencing, and unfortunately, Toyota has refused to cover the repair costs. What’s more concerning is that I’m far from the only one — many other owners are dealing with the exact same issue. It’s clear that Toyota needs to take responsibility and implement a proper solution to protect the condenser moving forward.

VEHICLE SPEED CONTROL

*Acceleration lag from a stop On June 21, 2025 - 92 degrees outside leaving store, I was making a left turn from a parking lot. I took my foot off the brake to creep forward which the vehicle did, but as I pressed the gas the car would not accelerate. I was stuck in the middle of the lanes with my car coasting. Fortunately it was a quiet street and the car coming from behind me had ample time to stop until i could coast my car to the side of the road which then it revved high and engaged. It felt like the car was in neutral but it was in drive. It lasted about 5 seconds. *It would not accelerate which was scary and very dangerous for obvious reasons. * I took the car to the dealership on the next business day and unfortunately cannot have it inspected until July 15, 2025. *No warning lamps, messages or other symptoms. *My car is available for inspection. That would be great! That’s why I brought it to the dealer but they were booked. *It happened only once, but I haven’t driven it much since the incident. I am now driving my 20 yr old, reliable MDX until I can get it inspected on July 15th

Shortly after starting my vehicle and driving out of my neighborhood, there are a series of stop signs. The roadway is at a slight incline. When attempting to press the gas pedal after stopping at the first stop sign, my vehicle hesitates or does not accelerate. This lasts anywhere from 1-5 seconds. This occasionally also occurs again at the second stop sign a few hundred yards later as well. The best I can describe this is as an unresponsive gas pedal or limp mode. I cannot stress how incredibly dangerous this issue is. Someone is going to get seriously injured or killed if this isn’t acknowledged by Toyota or NHTSA. All it takes is for this to occur when someone is making a right hand turn into a roadway. I am fully aware that this is not an isolated incident with my vehicle and other vehicle owners of Toyota Hybrid Max Platinums report this same issue.

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.

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.

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.

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

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.

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.

After shutting engine off, there is a gasoline smell coming from the vehicle. This repeatedly happens. I took the vehicle to the dealer who did a variety of tests but could not diagnose or fix the cause. The result is I cannot safely park the vehicle in my garage. I have requested that the complaint be sent to Toyota on January 15. No response or acknowledgment as yet.

Check axel joint problems. Every time the car turns either way there is a loud clicking sound. This could be a big problem because it is a steering system. It has been confirmed by the dealership and part are on order. They said it is not a safety issue but I feel the steering and axle is a big component and if it fails it could result in damage of property or life. This has not been inspected by the police or insurance only the dealership confirmed it. There are also many others with this type of vehicle having this problem. There were no warning lamps or anything to show something was wrong only the loud clicking noise.

CV joint/ axle malfunction. Vehicle is at 15,000 miles and both front cv joints and axles needed to be replaced. Only highway driving done. Many people are reporting that this happens and is fixed then continues to happen repeatedly after. This needs to be a recall! Owners should not be responsible for faulty equipment like this. There is a popping grinding noise when turning the wheel and accelerating.

Vehicle does fill gas tank to capacity of 17.2 gallons. It only fills about 12 gallons. It has a 2.6 gallon reserve so only fills about 14.5-15 gallons. The reserve is not included in range est on dash. Vehicle gets 230-270 miles per tank. You have to pull gas nozzle half way out to even get this 12.9 gallons - gas almost overflows to get this done. If your est millage left is 44 miles you can only get about 10 gallons in. The gas overflowing when trying to get more gas in the car is common. Many complaints online. This is a safety issue and known by Toyota and dealerships.

ENGINE

Since December 18, 2024 I have had this happen 5 times. I come to a complete stop and have my foot on the brake. The car will then hop four-five times (like the sensation of shifting in manual with a cluch and you don’t shift correctly and the car will hop). I am not sure why this is happening. I took it to the dealer and they haven’t experienced the issue. This doesn’t happen at every full stop either.
