Fuunny Noise

Hi: I have a Toyota sienna 2005 model with 39K miles on it. When I drive it at lower speed it makes some funny noise. I think its coming from an enfgine and the van vibrates a lot. You can feel something is wrong while driving it. But I am not sure whats wrong with it. Any idea?

the vibration is probably a wheel weight fall out, go get your wheels balanced. tell me some specifics about the noise

That should be under warranty so why ask. Take it back to the dealer and let them take care of it. They will not want to have you tell them what the problem is anyway, they just want to hear what your ccomplaint is, so just tell them what you told us and let them fix it under warranty.
