At 2400 miles. My Toyota Sienna start having windows problem. It is very new car. After numbers of repair. This Sienna-still both passenger front and rear windows will automatically roll back down when getting to the top. And back door can not be closed completely. Especial recently. I feel this is very dangers. Because this van windows up and down it is very danger for my 2 years old baby. It may cut his hand. I do not want this terrible van anymore. This van really make me headache and worry. If this van has no problem. I will definitely not bother anybody. But in fact. This van really cause problem. And bad thing is after visited several different dealership. Problem is still happening. If Toyota can fix problem. Customer has nothing to complaint. What can we do about this. I am very very disappointed with Toyota quality control system. I am a very disappointed with 2 Toyota dealership(clarement dealership and john elway's crown dealership)because I went to these dealership many times, what they have done is problem still existed. I am planning to try 3rd Toyota dealership. This is my first Toyota. And experience let my wife and I feel very bad and very headache about this kind of quality.
