2018 TOYOTA HIGHLANDER — Problems, Recalls & Safety Data

I purchase a 2018 Toyota Highlander in 2021. The vehicle had just over 8000 miles when purchased. The vehicle had manufacturers warranty but I purchased additional extended warranty in addition. I can review and find the dates but I don’t have it at the time I’m filling out this form. In any case, there was an issue with the passenger side door lock actuator not properly functioning. The door would not lock when using the key fob. Since the vehicle was under warranty, they replaced the actuator. In February or March of 2025, the passenger side rear door lock began with the same issues. The dealership diagnosed as another door lock actuator. The vehicle was still under warranty so the actuator was replaced. The actuator was ordered but not replaced until after the vehicle extended warranty had expired. Shortly before the second actuator was replaced, the front driver side lock began to give issues. It will not unlock or lock at all. The only way to get the lock engaged is to manually lock the door. In addition, the driver’s side rear door lock has quit functioning as well. I have reported the issue to the dealership but they have claimed they cannot repair since the warranty expired. The tech at the dealership (Rusty Wallace Toyota in Morristown, TN) told me that he has saw this issue in several highlanders. The safety issues is that the locks do not function unless manually engaged. If a child is in the rear seat, the door can be opened. When exiting the vehicle, the doors can be left unlocked inadvertently and unauthorized access can be gained to the vehicle leaving property at risk. I am in the process of getting these two no. Functioning actuators replaced but have been quoted a price in excess of $500 for the parts and labor. I have done some research and it appears this may be an issues on Highlander models 2009-2024. I can provide work orders to the actuators that have been replaced.
