ELECTRICAL SYSTEM, UNKNOWN OR OTHER, BACK OVER PREVENTION: WARNINGS
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.

VEHICLE SPEED CONTROL
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.

Sunroof spontaneously exploded leaving an 8” hole and a completely shattered sunroof. The sunroof is flexed upwards like it was under extreme pressure. The high temperature was 70 degrees in Tuscaloosa today with cloudy skies and misty rain. So there shouldn’t have been any concerns from heat or cold. This left shattered glass every above the sunshade. Fortunately the shade was closed to catch most of the shattered glass.

FUEL/PROPULSION SYSTEM
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.

Front windshield cracked on its own. Car was parked in driveway and there was nothing affecting the crack. It cracked on its own. This is brand new car Grand Highlander 2026 and owned for only 1 month. The front windshield shod not crack like that on its own out of nowhere. I read many other reviews from other owners facing the same issues. Most of them mentioning that this has happened because of the poor installation and some mentioning that even after replacing the windshield it has cracked again. Toyota should address this as a recall asap. For a car that costs $60,000.00 and not being able to install a proper front windshield is very sad to hear it from Toyota. That was number one reason I went to buy the Grand Highlander Limited 2026 thinking that there wont be any issues but the stress started already to accumulate. What could be next?

ELECTRICAL SYSTEM, POWER TRAIN
The contact owns a 2024 Toyota Grand Highlander. The contact received notification of NHTSA Campaign Number: 25V595000 (Electrical System), and the vehicle was taken to the dealer on several occasions, but the dealer informed the contact that the part to do the recall repair was not yet available. The contact stated that the instrument panel had failed. Additionally, the contact stated that the vehicle was not driving properly, and the vehicle was shuddering while exceeding 70 MPH. The vehicle was taken to the dealer, where it was diagnosed with an axle leak, and the contact was informed that there was no warning light illuminated for the failure due to the instrument panel failure. The axle leak was repaired; however, the failure persisted. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure, and a case was filed; however, no assistance was provided. The failure mileage was approximately 9,000.

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.

We were going down the highway in our brand new Grand Highlander yesterday (3500 miles, 3 months old) and it was like a bomb had gone off. The panoramic sunroof exploded up and out. Glass started falling on my daughter whom was in the middle seat. My husband had to quickly pull off the highway to safety. I have never experienced anything like this and it was extremely scary. Obviously there is a defect that needs to be addressed.

Dear National Highway Traffic Safety Administration, I am submitting this complaint to formally report a serious safety issue involving the left front axle of my Toyota Grand Highlander Hybrid XLE. The vehicle was first diagnosed by my local Toyota dealer on January 14, 2026, at which time the left front axle issue was identified. I contacted **Toyota Motor Corporation**, and I was initially informed that the required replacement part would arrive on February 6, 2026. After that date passed, I was told the part would arrive in early March. I have now been told it will not arrive until late March. Based on these repeated delays, I am concerned that “late March” could easily become late April or even later, with no firm commitment or guaranteed repair date. I have contacted Toyota dealership multiple times and made several phone calls seeking assistance, updates, or a definitive timeline. Unfortunately, no one has been able to provide a clear solution, firm delivery date, or alternative support while the part remains on back order. Due to the axle issue, I do not feel safe operating the vehicle, as I believe it presents a significant safety risk. This vehicle is essential for my work and daily financial responsibilities. Because I do not feel it is safe to drive, I am unable to use the car to earn my day-to-day income and meet my financial obligations. As a result, I am currently losing wages, and the prolonged delay is causing financial hardship and significant inconvenience. Given the safety implications and the ongoing lack of resolution, I respectfully request that the National Highway Traffic Safety Administration review this matter. I would appreciate guidance on the appropriate next steps, including whether this issue warrants further investigation, inspection, or potential recall action. I also seek clarification regarding what protections or remedies may be available to consumers when critical safety components are unavailable for extended periods.

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.

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.

At a complete stop my car started shaking violently back and forth. It felt like we were in an earthquake. It has happened before but not as violently and not as long. No warning lights or anything. It has had problems with lurching and stuttering since we bought it. The dealership said they fixed it once (the stuttering) but it’s still happening. They cannot duplicate it and it’s not throwing any codes.

ELECTRICAL SYSTEM
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.

The entire life of the car from initial purchase the fuel gauge is incorrect. The car has a 17 gallon gas tank and the fuel gauge is calibrated to around 13 gallons. The car thinks it is out of gas around 13 gallons when there is actually 4 more gallons left.
