2024 Toyota Grand Highlander Complaint Log

Cabin boom noise reported from the first day of ownership whenever driving the vehicle under 50mph. Noise is a low bass frequency below 30hz that reverberates throughout entire vehicle, causing severe ear pain, headaches, nausea, and disorientation. The only way to tolerate driving this vehicle is to wear airplane pressure earplugs, which poses a safety concern for not being able to hear surroundings while driving. The cabin boom seems to be coming from the suspension. Dealership foreman and corporate field tech looked at vehicle and denied any problem, stating this was “normal for this new vehicle” and refused to investigate or try any diagnostics. The cabin boom sound is recorded on video, and is such a low frequency you must use noise canceling headphones to hear it on video (confirmed by professional audio engineer). This sound/pressure can be heard and felt by other people in the car, unless they already have low frequency hearing loss. This problem creates physical illness and is a huge safety concern for this brand new model Grand Highlander. Dozens of people are reporting the same problem on Toyota forums as well for their new Grand Highlanders.

“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

The rear portion of the hood, closest to the windshield vibrates or flutters at speeds above 30 MPH. At speeds above 50 MPH the flutter becomes very noticeable and actually reflects sunlight into the driver's field of vision. I had personally been blinded by this for several seconds - a very dangerous situation on a busy interstate highway. Fortunately the vehicle's lane keeping assist kept me in the lane but I otherwise could very easily have swerved into another car or rear-ended a stopped vehicle. I have taken this vehicle to my local dealer and a technician reproduced the problem very easily. I was told by the service manager, however, that this is a normal condition for this vehicle and suggested I contact Toyota.

There is a huge hole in the undercarriage starting at the back of the vehicle and runs all the way to the front of the vehicle. Hole is large enough a child can climb in without anyone knowing and could possibly die if car is in motion.

When turn left or right i hear a rotating poping noise only goes away when you go straight. I have hread others complaining about the issue. To my understanding and knowledge the axles are bad. This can cause premature failure in other suspension parts and tire wear.

Every time we turn in the vehicle it knocks/clicks. A lot of research shows the CV Axle is causing this problem.

The entire proximal portion of the hood closest to the windshield vibrates above 50 mph. Windy conditions make this worse. The glare on the hood will vibrate distracting the driver. I have reported this to Toyota and they do not care to acknowledge it as a problem. There are forums of new honors of the Grand Highlander complaining. My dealership could reproduce the problem and said there is no fix.

The hood vibrates at 50mph on the back 1/4 th closest to the windshield. It’s very distracting while driving. I also had an incident where adaptive cruise control in light rain did not appropriately anticipate traffic up head and I had to slam the brakes myself.

Faulty CV Axles installed on 2024 Grand Highlanders. Toyota is aware of the problem and have edited the production of newer models. They have not issued a bulletin or recall for the ones installed in older models. Older meaning in the last year. This is a brand new vehicle. It started making noise when turning 2 weeks ago. The noise has gotten louder and occurs with every turn. It initially only made the noise when turning on an incline. If the axle fails, you lose control of the entire vehicle. Several dealerships have had to service and replace the axles, so Toyota needs to formally recall the ones installed in earlier Grand Highlanders before someone gets hurt. The vehicle sensors do not detect this issue. It was detected from sound and service at a Toyota Dealership.

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.

The center console display stopped working the next day I picked up my car. This display also displays the feed from the rear-view camera, which is flaky because of this issue. The center console display enters a reboot cycle; it reboots every minute, distracting me while driving. I picked up this new vehicle on Dec 15, 2023. This issue started occurring on Dec 16, 2023.

I was driving around town and a loud bang, almost as loud as a gunshot. My moonroof had shattered into thousands of pieces.

Toyota provides the ability to use a phone for a key. Only one key was provided due to chip shortages. My phone has been registered as a key. I left my home with only my phone. Upon coming out of the store my phone would not open the door after trying numerous fixes including calling Toyota. My wife unlocked the car remotely via satellite. Trying for 20 minutes with Toyota we could not get the vehicle to recognize my phone. My wife had to drive the only set of keys to my location. The vehicle still wouldn't start until I unlocked the vehicle with the FOB. Had this issue occured in a remote area without cell service I would have been locked out of my vehicle with no way to call for help.

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.

side mirror vibrated badly with out music turn on. with music, shaking likes dancing

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. Toyota has not offered any acknowledgment or a fix.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that the infotainment system screen display turned black intermittently, preventing the contact from accessing the safety features as needed. An unknown warning light was illuminated. The contact also stated that the third-row driver's side seat was stuck after being folded and failed to unfold as needed. The vehicle was taken to the dealer, where it was determined that an unknown part had detached. The dealer repaired the vehicle; however, the failure recurred. Additionally, the contact received notification of NHTSA Campaign Number: 24V461000 (Air Bags); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000. VIN tool confirms parts not available.

Very loud Popping/clicking noises when turning/accelerating from a stop. Only had 2,162 miles on the vehicle when this happened. While driving, it also felt like my front driver side wheel was wobbling-very unsafe. Called Toyota roadside assistance and had car towed to dealership. Lead service technician was able to reproduce the popping and clicking noise. Dealership opened a case with Toyota, and had engineers come look. 10 days later, they called to tell me that they have to replace CV axle. Car was in the shop 18 days total. This problem shouldn’t be happening to a brand new car with 2,000 miles on it. There are MULTIPLE reports of this same thing happening to MULTIPLE Grand Highlander owners-on a “Grand Highlander Owners” Facebook page. Some have had to have both cv axles replaced.

New Grand Highlander started making popping noises when turning at approximately 1000 miles. Dealer has replaced axles twice saying they were defective and the issue remains. We were told there was an issue with the axles during manufacturing and they are now on backorder. Our car has been in the shop over 30 days and we are told it is not safe to drive until new axles are installed.

I purchased this vehicle in Canada and I need to use this vehicle in United States roads as well. Toyota is reluctant to confirm this vehicle is meeting Federal Motor Vehicle Safety Standards except labelling and it is safe to drive in United States roads. This vehicle is equipped with TPMS but it is not listed as a part present in the vehicle which makes me worry. Request you to probe this requirement and make me and my loved ones feel safe in driving this vehicle.

Hope this email finds you well. I am writing just to give some feedback about my brand new Grand Highlander Platinum. Unfortunately, I have been noticing some issues with the hood (vibrating) at any speed which raised a huge concern about the safety of my family as it seems like the hood is going to fly away from the vehicle (at high speed like 50 mph or more). The formal response received from 2 different dealers is: We just got off the phone with the Toyota technical specialists about the concern with the hood. They have one other case open for the same complaint but are telling us there is no safety concern at this time and to release the vehicle back to you. We did test 2 other Grand Highlanders and they are both doing the same thing. My personal opinion is that due to the lightweight nature of the hood it is susceptible to flex and is showing that movement more obviously because of the black paint’s reflection properties. In my experience, if more of these cases arise, the manufacturer will open an investigation into a possible resolution but at this time we have been instructed to take no action. If you want I can send you some videos about the vibration. As you can see, the answer does not make sense since it is uncomfortable to see how the hood moves while you drive. I think it is important that customers know this defect before investing money in this vehicle.

I purchased the car in the middle of September 2023. Within a week of owning I noticed that there was a clicking sound under the steering wheel when I started to turn to the RIGHT from a stop. Several weeks later the clicking sound began when I made a turn to the LEFT from a stop as well. It happened all the time and gradually became louder. When I took the car in for the 5000 mile service and reported the sound, I was told that Toyota was going to change both front axles. The service manager could not tell me what the problem with the car was but that he was told by Toyota that the car was "safe to drive." I refused to drive the car until the axles were replaced and Toyota promptly provided me with a rental car. When the axles were replaced the car drove very differently. The steering was tighter and the car no longer felt like a "bathtub" on the highway. Previously, the car would float and have poor road feel, I worried about its response to an emergency maneuver and consequently drove the car very conservatively. I was disappointed that my new car did not feel like the Grand Highlander I drove as a test before purchase. Now with the replaced axles the car's response is similar to the test vehicle and I am much more confident in its emergency handling. I fear that there is a serious problem with some of the Grand Highlander's front end. I wanted to alert the NTSA on a potential hazardous situation, especially since Toyota is recommending that the affected cars be continued to be driven despite the identified problem with a major component.

Bought in September 2023, within the first month, it started making a clunking noise when the wheel was turned to the left. The noise continued to get louder and started to make the same noise when turning right. In November, I got in my vehicle and it wouldn’t start. The dash and everything was flashing and making a cranking noise. I took it to the nearest dealership. They “charged” my battery and said it was fine. Also stated the noise was a heat shield issue and they fixed it. As soon as I pulled out of dealership, it still made the noise. The next morning went to start car, battery was dead. Had it towed to dealership for them to replace the battery. I filed complaint with Toyota, a field tech guy looked at it and said it had a bad left CV axel. No warning lamps/icons. But…Dealership's said it was safe to drive. However, If it fails, it can cause the vehicle to stop or tires to lock up. Causing an accident! It can also cause more damage to vehicle parts/ transmission. Furthering decreasing the value of the vehicle.

Vehicle has popping noise and can feel vibration under driver side pedal area when turning the vehicle. Reported to Toyota right after purchase and was told everything was okay but popping continues and has gotten worse over time.

I wanted to open the hood using the hood support rod. Holding the hood with left hand using right hand grabbed the support rod . It burned my fingers immediately.Looking at the designed it is placed in the center of the hood underside right above engine compartment.It took one week and 3 phone calls to Toyota product liability area. I told him I learn my lesson the hard way that I will never grab it again without a glove. It is that hot I asked him why would they design a bar above the engine compartment which will except all the heat from the engine, I looked in the owners manual and I read it to the Toyota person I contacted and this is what it says and I quote the support rod may be hot after driving the vehicle. Touching the hot support rod may lead to burns or other serious injuries so I told the representative at Toyota they put this in the book knowing that people are going to get burned or drop the hood when their hand gets burned and it’s gonna fall on their head or it’s going to hit their hand. Why would they design something so poorly like this he thanked me for letting him know about it I asked him what will someone be back in touch with me to validate my concern and that they’re looking into it and he said absolutely not he said if there’s any recall, I’ll get notified by mail. Thank you very much is all I got from them

Hood vibrates, and on sunlight or cloudy days the light flickers in your vision. This is a safety concern that Toyota says is a normal characteristic of the vehicle. NOT.

Dash board appeared safety issue warning and ask to contact dealer. I have been to dealer 3 times since bought the vehicle last year. The first time it appeared was after I bought the vehicle for a week. I brought the vehicle back to the dealer and ask for a refund or exchange another one, and was denied. I happened 2 more times and I brought in again. They said that they adjusted the sensors for a less sensitive level. I contacted toyota to exchange or return the vehicle last year. They got my information down and never replied to me until now.

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.

The vehicle randomly won’t go when starting out from a complete stop. You can push the gas pedal to the floor and it will barely move. Almost got hit in an intersection trying to make a left turn. Toyota is aware of the problem and has a TSB and did an ECM update but the problem persists. It’s scary when it happens. Can’t trust the vehicle.

Published 2024 Toyota Hybrid Grand Highlander (TGH) specifications, the TGH owners manual and dealer information provided indicated the vehicle has a 17.2 gallon fuel tank. However, the most fuel I am able to get in the tank is between 11 and 11.5 gallons. I've had the vehicle in to fix the defect on three occasions; 2023-11-27, 2024-3-11, & 2024-8-13 to no avail. On the second service, Toyota's technician said the tank had 16.8 gallons remaining when I picked it up, I had filled it the previous day and driven approximately 15 miles. Once the gauge showed near empty with only a few miles left of fuel, I filled the tank and was only able to get 11.4 gallons in the tank. There appears to be six gallons of fuel that I am carrying in the tank that the fuel system cannot access. I have searched on-line and found that a number of other TGH owners are experiencing a similar defect.

I have had 2 intermittent issues since I bought this vehicle brand new. 1) Hard, Jerky shifting from 1-2 or 2-3 gear 2) Huge safety issue regarding loss of power and inability to accelerate from a stop even though the car is on and in drive. This has happened to me multiple times and is very intermittent so it is hard to replicate. This has happened when I am attempted to accelerate from a complete stop and the car begins to move but then does not accelerate at all. Almost as if the powertrain shut off even though it was moving under its own power a fraction of a second ago. This has happened to me multiple times with my entire family in the car as we attempted to enter intersections leaving the car powerless with oncoming traffic. Thankfully we were not hit by another car but could have been.

The vehicle main screen on the dash will not go past the “get started” screen without accepting Toyotas privacy agreement on their app. I cannot use the screen as it defaults to this screen each time the car starts and does not allow a menu to the feature I paid for. This is both a safety and privacy issue as I should be able to use the vehicle while not agreeing to the privacy policy and I should be able to access the screen without distraction from driving. I explained to the salesmen I did not agree with the privacy policy and have been able to navigate the vehicle without issue in my 2014 and 2021 Highlander. I contacted Toyota and there is not work around. The manufacturer will not provide a solution other than removing all my safety features, which did allow me to get past the Home Screen. I asked to return the vehicle because I cannot use it and was refused. I would like to be able to protect my privacy and be able to use the screen I paid for without offering access to cameras and other location and audio recording devises on the vehicle.
