Greetings. I am new in this forum. I have 2008 Yaris sedan, purchased in March of this year. Very basic, standard. The noise I hear is like a vacuum. You know vacuuming a house. And it is loud that even when my radio is on I hear the loudness. My Toyota salesman mentioned that it will go away when I picked up my car. That means to say, he noticed or know it. What could be wrong. I have 3000 miles already and I am not happy with the noise. Do you think I can trade it in the same dealership and get a Corolla?

You might consider posting this in the 'Yaris' forum. This is more 'Avalon' centric...

Before you trade it in and take a huge loss on it, why not take it back to the dealership and complain about the noise. Perhaps there is something they could do to fix it.
