Selected complaints filed with NHTSA by 2022 Toyota Highlander owners, lightly cleaned up (personal details are redacted by NHTSA).
Car fire (total loss of vehicle) after hybrid malfunction. My family and I were traveling west bound on [redacted] near Crawfordsville Indiana on [redacted]. Trooper Chelsey Smith from the Indiana State Police (CAD # [redacted] ) came to the scene. Our car was traveling westbound at about 70 mph when I got a notification of "a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected" - I acknowledged the alert and kept driving, then it showed again 30 seconds later and acknowledged again. About 30 seconds later I received a "Hybrid System Alert" stating "A malfunction in the Hybrid System has been detected. Stop in a save location and contact your Toyota dealer to have your vehicle inspected". …
The contact owns a 2022 Toyota Highlander. The contact stated that while driving 70 MPH in the fast lane, the steering wheel failed to respond as needed while attempting to turn to the left or the right. Additionally, the brakes became inoperable and the vehicle decelerated. The contact stated that several unknown warning lights were illuminated. The contact was able to veer to the shoulder, and the vehicle shut off. The contact called Roadside Assistance and was informed that the battery needed to be replaced. The vehicle was taken to an independent mechanic, who informed the contact that the failure was due to the engine. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 17,781.
The contact owns a 2022 Toyota Highlander. The contact stated that while driving at an undisclosed speed around an S-curb, the vehicle jerked into the nearby lane. The local dealer was contacted. The failure mileage was approximately 55,000.
The contact owns a 2022 Toyota Highlander. The contact stated while driving 35-40 MPH and attempting to accelerate to enter the highway, the accelerator pedal was depressed; however, the vehicle responded sluggishly. The vehicle emitted abnormal sounds as though the transmission was in neutral. The contact depressed the accelerator pedal all the way to the floorboard and the vehicle responded as intended. There were no warning lights illuminated. The contact was able to continue driving. Additionally, the contact stated that while driving 40 MPH, the brake pedal was depressed but hesitated to respond, causing 20 feet stopping distance delay. The contact stated that the failure mainly occurred in wet conditions, snowy conditions while driving approximately 60 MPH. The vehicle was taken to the dealer and test driven. …
While driving my 2022 Toyota Highlander (VIN: [redacted] , 29,427 miles), I have experienced multiple recurring safety defects that Toyota has been unable or unwilling to repair under warranty. Front collision sensors frequently trigger without any object present, creating a risk of unexpected emergency braking at freeway speeds. Transmission hesitates and surges unpredictably, sometimes propelling the vehicle into traffic. In heavy rain, my windshield wipers activated on their own and multiple system failure warnings appeared (including ABS failure), nearly causing a crash. Persistent startability issue when fuel is below half a tank. Seatbelt malfunction caused a passenger to strike their head. Seat heater failure, seat separation, persistent coolant odor, and nonfunctional factory wireless charger since purchase. …
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. …
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. …
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. …
While having the eco system on, with the active system present by firmly pressing the brake hard at a stoplight, the light turned green. while taking my foot off the brake and the engine turning back on, attempting to accelerate the transmission would not allow me to get through the intersection turning left. I pulled to the far left/slow lane to stay out of other traffic. The vehicle would not allow me to go past 40mph, and the rpm's would rev between 2000-3000 at low speeds between 10-25 mph. I had my 1 1/2 year old with me in his car seat, and it would have been tragic should this happen on the freeway and this kind of situation happened. Attempting to take it to the dealership, the truck even had trouble going over some railroad tracks with a small mound present. …
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.
