2024 Toyota Grand Highlander

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.

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.

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.

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.

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.

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.
