On October 22, 2026 at 7:55pm I was slowly pulling into a parking spot at our community building applying the brake when the engine started rapidly accelerating causing the car to jump over the curbing even as I continued to press on the brake pedal. I wasn’t able to stop the vehicle before it crashed into the community building wall. The engine was still racing but the vehicle being lodged in the wall and corner support kept the vehicle from going further into the building. I was finally able to shut off the engine and luckily for me the airbag system didn’t deploy.

I am writing to formally express my dissatisfaction regarding a failure of the power liftgate on my Toyota Highlander and the fact that I was required to pay out of pocket to have it repaired. The liftgate is an important and frequently used component of the vehicle, and I did not expect it to fail under normal use. When the liftgate stopped functioning properly, I was faced with an unexpected and costly repair expense. I believe Toyota should take responsibility for this failure, particularly given the nature of the component and the circumstances surrounding the repair. I purchased my Highlander with the expectation that Toyota’s reputation for quality and reliability would be reflected in the vehicle. Having to pay for a repair resulting from a failed liftgate has been extremely disappointing and has diminished my confidence in the vehicle and the Toyota brand. I am requesting that Toyota review my situation and consider reimbursing me for the cost of the repair. I would also appreciate an explanation as to why this failure occurred and whether Toyota is aware of similar liftgate issues with this model. I am happy to provide my repair invoice, vehicle identification number, mileage, and any other documentation necessary for Toyota to investigate this matter. I hope Toyota will take this complaint seriously and work with me toward a fair resolution. I look forward to hearing from Toyota regarding reimbursement and what can be done to address this issue.

The only door that will lock or unlock using the fab key or the master lock button on the drivers armrest is the drivers side rear door. My vehicle is not able to be locked unless I do it manually and can not be unlocked unless i use the rear drivers side door. This has been reproduced by the dealership. There were no warning lamps or messages and no other symptoms. This has been going on for a month. I am being told by the dealership service department that 3 actuators failed at the same time. My lift gate also malfunctioned this year. Dealership diagnosed it with needing new struts. Not sure if this is related. Lift gate would not open or open only a small amount. This was using the inside button and the outside one as well.

Motorized struts to lift and close the rear lift gate have failed. The struts do work to open the lift gate but they do not work to close it. Manually closing the lift gate is extremely difficult because of the electric motors inside of the struts. A known problem by Toyota as they have issued a TSB. Toyota’s solution is to replace the struts at a cost of $1200. My concern about this being a safety issue: Closing the lift gate after accessing the spare tire is extremely difficult. If my wife would inadvertently open the lift gate, which does work, after leaving the grocery store to put all of the groceries in the back, she would not have the strength to manually close it. Obviously, the vehicle cannot be driven with the open tail gate. This is not any different than if any of the doors could not be closed due to defective hinges. The premature failure of motorized struts is a fairly common problem with Highlanders. ToyotaNation, which is a Toyota sponsored forum for owners to communicate with other owners about issues/problems, contains numerous posts about the failure of motorized struts on the rear lift gate. Your attention to this matter is greatly appreciated. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle: 2022 Toyota Highlander Limited Mileage at failure: ~60,000 miles The driver seat began moving rearward without any driver input while the vehicle was being driven. The movement was intermittent and occurred multiple times over several days. In one incident, the seat moved rearward while my wife was driving, causing her to lose proper reach to the brake pedal and nearly lose control of the vehicle. The seat would sometimes move to the full rear position and continue attempting to move past the mechanical stop. The problem also occurred during vehicle startup and shutdown cycles. This condition creates a significant safety risk because the driver’s seating position can change unexpectedly while driving. In attempting to mitigate the problem, I tried to disable the power seat by removing the fuse. However, the power seat fuses on this vehicle are not clearly labeled and are mounted on the side of the interior junction block under the dash, making them inaccessible to the driver without removing interior panels. As a result, the malfunctioning system could not be quickly disabled. The vehicle required replacement of the driver seat control/track assembly at a cost of approximately $1,600. Uncommanded movement of the driver seat while driving appears to be a safety-related defect and should be investigated for potential recall or service campaign
