2024 Toyota Grand Highlander

It didn't work it didn't brake or didn't have an alert in which caused an accident

The incidents most often occur when I try to accelerate after vehicle is stopped at an intersection. The car hesitates during acceleration regardless of how much I push the gas. Once it starts to go, it feels as though the car can't shift from 1st to 2nd gear. The RPMs get up 4500 while the car is going 25-40 mph and remain there for a few seconds up to ~20 seconds. I am fearful of getting t-boned when my car hesitates while turning at an intersection, going through an intersection or pulling out from a parking lot. I have been stuck in several intersections when traffic was coming toward me, but thankfully those cars were able to avoid hitting me. I have reported the problem every time I take the car to the dealer for a service. The problem has been happening since I purchased the car in November 2024 and occurs randomly--sometimes every couple of months, sometimes days in a row. The dealer can't reproduce it, but they were able to pull a code from the transmission and found it had an acceleration error. They updated the software from a TSB, but that didn't help.

Reported issues of lag in acceleration and harsh shifting into reverse, the vehicle has been brought to the dealership multiple times stemming from shortly after previous, there are no warnings lights on. I requested the dealership provide in writing if the deemed the vehicle safe for operation. They would not do so. I requested a loaner while my vehicle is being reviewed for repurchase and was denied. When my repurchase claim was denied, I requested a reconsideration and again a loaner.

My car read system malfunction and come to find out there was corrosion with the wires in the internal circuit of the driver side mirror that prevents it from warning you of blind spots and pre-collision.

The transmission needs to be replaced per the dealership. I was told this on 3/7/26 with mileage of 69K. The transmission has been reported as defective to Toyota since 2016-2017 with multiple lawsuits that have been filed. According to the lawsuits found online, Toyota knowingly used the defective UA80 transmissions and failed to inform consumers when purchasing the vehicles or inform consumers the need to replace prior to the 60k warranty expiration. The 2024 Grand Highlander has been listed as one of the affected vehicles and the transmission can fail at any time which is a safety risk.

My car suddenly shook violently while at complete stop at a stop light. Also, the brake feels weird at times when slowing down.

I am submitting this complaint regarding a catalytic converter failure on my vehicle and the manufacturer’s refusal to honor the warranty. My vehicle is a Toyota that is approximately two years old and currently has about 31,000 miles. The catalytic converter has failed well before what would normally be expected for this component. When I brought the vehicle to the dealership for repair under warranty, Toyota declined to cover the repair. They stated the failure was due to “contaminated fuel,” but they did not provide any evidence or test results showing that contaminated fuel was present in the vehicle. I have not been provided with documentation, diagnostic data, or fuel analysis supporting this claim. The denial appears to be based on assumption rather than proof. Because catalytic converters are emissions components that are typically expected to last much longer and are often covered by extended emissions warranties, I am concerned this may represent a broader issue affecting consumers. Vehicle details and service documentation can be provided upon request. I am requesting that this matter be reviewed and that the manufacturer be required to provide evidence supporting their claim or honor the warranty repair. Thank you for your time and consideration.

I had my front axle assemblies replace under T-SB-0082-24 around 20,000 to 25,000 due to rotational clicking noise per bulletin. The tsb uses the old part number which was the defective original part. The axles are failing agin at 50,000 and the dealer and toyota are refusing to fix it as they can’t replicate in shop. There is a new part number that was updated and supposedly fixed the issue but that is not the part that was installed in my car. They stopped the production line and updated the part at one point supposedly there was not enough grease in the cv joint boots causing premature wear. The old part number is still listed in the tsb even though it is superceded, tsb should be update or recall issued for all affected models to get the new updated part. Old part number 43420-0E340 new part 43420-0E341. Other side old part 43410-0E520 new part 43410-0E521. Toyota installed the old obsolete parts on my car in all paperwork for my work history and is refusing to install a working set of axles.

I own a 2024 Toyota Grand Highlander Hybrid and am experiencing an intermittent knocking/clicking noise that appears to come from the drivetrain area. The noise occurs most often during low-speed driving and while turning left or right, particularly on the first drive of the day after the vehicle has been sitting overnight, but it has also occurred at other times while driving. The condition is intermittent and does not occur every trip, however it has been heard by multiple drivers. The noise is most noticeable during light acceleration combined with steering input at lower speeds. I have brought the vehicle to the dealership for inspection, but the condition has not yet been duplicated during testing. I am concerned this may indicate a developing drivetrain or axle-related issue that could affect vehicle safety if it worsens while the vehicle is in motion. I am submitting this report so the condition can be documented and evaluated for potential safety concerns affecting this vehicle model.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that the display was not functioning properly, and the screen was blank while operating. The contact stated that after the "Get Started" prompt was displayed and selected, the screen would go blank. Additionally, the back over prevention camera was inoperable. The vehicle was taken to the dealer; however, the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 22,679.

In the middle where the car chargers are – the one in the center isn’t working but the one to the right is. When doing maps, the visual map disappeared and just showed where to turn – happened about 2-3 time. Today the entire screen went black – no radio, phone, maps, nothing. No way to operate it at all. This is unrelated to the current recall that addresses the speedometer / display right behind the steering wheel.

clicking noises from front of engine area/tire area whenever steeing wheel turned left or right turned out to be cv axels and replaced feb 2. 2026 -so far will monitor for recurrence - grand highlander forum with numerous such complaints

When I turn to the left or right I hear a clicking/popping noise. Took it to the dealer and they said it was the CV axle. So they replaced the driver side. After the repair, it would make the same sound from time to time so I took it back in to the dealer(Northside Toyota in San Antonio, TX) they couldn't recreate the sound and notated my account. This was all when the car had less than 30k miles. The grand highlander now has 47k miles and it is making the noises alot more. Im on a grand highlander forum and a lot of other owners are having the same issues. Some are already on their 3rd set of cv axles.

I was driving toward the perimeter of my neighborhood, approaching an arterial cross street. When I braked the pedal went straight to the floor. The breaks didn’t work despite pumping them multiple times. I also heard the engine revving. To avoid the intersection and busy street I steered into a yard, hit a retaining wall and a tree, rolled and hit a metal city street sign. All airbags deployed. I was taken to the hospital by ambulance. The car was totaled and is on a temporary hold at a salvage yard.

I have taken my vehicle to Wilde Toyota (2 time) for the same issue . The car either moves/slids to the left or right. They adjusted the wheel alignment in November and now again I am having the same issue. Took the car again to Wilde Toyota and they are asking me for 185 USD for the wheel alignment. I told them this looks like a drive train or suspension issue but there were hesitant to check it.

UNKNOWN, vehicle dash warnings advising front sensors were not working causing error messages. The vehicle was taken to the dealership for a recall and they advised the Right front Ultra Sonic Sensor also needed to be replaced. They alleged this was potentially caused by an unknown impact such as small rocks or bugs. The faulty sensor causes error messages on the dash and needed to be replaced. They would not cover this under warranty which is a repair cost of $823.81. The only other band aid was to turn of the other sensors to get rid of the dash notifications, not allowing the other sensors to work as designed to monitor items or people in front that may not be seen by the driver. This turns off some of the vehicle's safety features. Toyota was directly notified of this incident but refused to cover the issue under warranty and expects consumers to pay for a new sensor and programing for a part that is faulty or not durable enough to perform under normal driving conditions. I am making this notification to NHTSA so there is a record of the issue with the durability of the Toyota Ultra Sonic Sensor or failing under normal driving conditions in case there are other complaints about the same issue.

This is regarding recalls for my 2024 Toyota Grand Highlander Hybrid Platinum Max. The vehicle has been in the possession of Koons Tysons Toyota since December 23, 2025 (80 days as of 3/11/26), for repair of Safety Recall #25TA13 and #25TB13 NHTSA 25V744) involving the Panoramic View Monitor System/Parking Assist ECU. The dealership has explicitly informed me that the vehicle is unsafe to operate and have therefore kept it. Toyota and its authorized dealer have made three (3) repair attempts to correct this safety defect. Two separate replacement components were ordered and installed without resolving the issue. A third required component is currently on backorder with no definitive ETA or repair completion date, as the date keeps getting pushed. We are not being updated and are not receiving information from the dealership and Corporate about the details about the problem and nature of the delay. Toyota has obligations under federal recall law administered by the National Highway Traffic Safety Administration (NHTSA) to remedy safety defects within a reasonable time and at no charge to the consumer. An indefinite inability to complete a safety recall repair due to parts unavailability raises serious concerns under those obligations. Furthermore, a previous recall #25TA08 (NHTSA 25V595) which was supposedly completed on October 14, 2025 by the same dealership is showing as INCOMPLETE in the vehicle record with NHTSA.

The contact owns a 2024 Toyota Grand Highlander. The contact stated that after driving into the garage and while pressing the brake pedal, the vehicle suddenly experienced unintended acceleration, lurched forward, and crashed into the husband's workbench. During the incident, the brake pedal was forcefully pressed, but the vehicle did not immediately stop. No injuries were reported. The husband's workbench was destroyed. The vehicle was later driven to the local dealer, who was unable to determine the cause of the failure. The manufacturer was notified of the incident, and an investigator was sent to examine the vehicle. The investigator reported that no trouble was found with the vehicle, and the crash was due to driver error. The contact insisted that no driver error had occurred, and the incident occurred while the brake pedal was being forcefully pressed. The failure mileage was 14,000.

2024 toyota grand highlander had TSB 0082-24 repair done around 20,0000 to 25,000 miles due to rotational clicking noise and vibration when turning under power. Both front axles replaced. Car now has 50,000 miles on it and clicking noise is present every day in cold conditions until it warms up. It is at the dealer for the third time and they are unable to replicate the clicking and vibration and will not replace the part. The symptoms are identical to when the first repair was done. Possibility of cv axle failure in the near future if not replaced. A full recall and redesign is needed at this point if I am experiencing 2 failures within 50,0000 miles.

Third row seating bottom (back side) has loose flap material end the bottom, when closing and opening the seat it’s can get stuck. It’s also possible the seat can probably even collapse while in use or in driving. The dealer tried to help but there doesn’t seem to be any solution for this from Toyota. This seems to be model wide issue as I was told by dealer. They had another one with same issue. The bottom back of the seat is literally loose flap material. The only solution was they replaced the cargo tray which was actually slightly BENT at front possibly due to seat struggling to close and opening due to faulty design. THIS IS A FAULTY DESIGN! ITS LITERALLY A LOSSE FLAP PLASTIC MATERIAL ON A SEAT BACK. The dealer told me to be careful when handling these seats bc the material can break easily and there isn’t solution from Toyota on this unless there is recall or safety notice.
