Example complaints

“The front driver window was making a clicking noise as if it were coming off the track. Eventually, the arm motor stopped all together and I had to replace the arm. Now the front passenger window is making the same noise and I'm afraid to open it. The leather interior is cracking badly on all seats. I rarely have passengers and condition the leather. I've had to use an adhesive to prevent additional cracking”
NHTSA complaint #11286771, filed 2019-12, 131,500 miles“The door locks on my 2012 Toyota Highlander stopped working. With only 17500 on the car, all 4 doors wont close with the key fob, or on the door. They open but dont close, I have to manually close each door lock every time I want the doors locked. I am the only owner, I bought the car brand new, and as soon as it came out of warranty the door locks stopped working.”
NHTSA complaint #10721143, filed 2015-05, 17,400 miles“Rear tailgate no longer works.started not closing off and on in jun. 2016. Finally stopped working all together in aug 2016. Took to my local dealership to see why it was not working they diagnosed it as a broken motor.I would be responsible for the cost to fix it.since it is now out of warranty. They would not cover it under warranty even though there is a Toyota service bulletin on it in 2012 and many class action law suits filed on it.”
NHTSA complaint #10895576, filed 2016-08, 39,000 miles“Car has over 117,000 miles and is excessively consuming oil. There is no sign of leaks anywhere. I do not get any warning anywhere about low oil, all I see is a small message that sometimes blinks indicating 'oil pressure'. Oil is not lasting 1000 miles. I thought maybe the oil was not properly filled but after a second oil change, same happened, oil empty with less than 1000 miles after an oil change. Car has been always kept with all recommended maintenance and all oil changes have been done every 5,000 as recommended by Toyota. …”
NHTSA complaint #11307417, filed 2020-02, 117,000 miles“The power door lock actuator went out on the rear passenger door if my 2012 Toyota Highlander. I only noticed the failure by chance. After my six year old son got out of the car one day, I tried the door handle and noticed it was unlocked. I hit the key fob lock button again, and the other three doors locked, but not that one. It turns out, the door had not been locking for months. I park in the driveway at home, and a remote surface lot at work, so essentially the contents of my vehicle have been wide open to theft for a long time. …”
