I bought the Base Rav4 in August, 2010. Everything is great, except it vibrates a lot and is very noticeable, especially at speeds greater than 50. The Dealership tried to help and rebalanced the wheels for me. It did not help. At the dealership, the service manager and I test drove another new Rav4 and it did the same thing. Called Customer Care at Toyota, and their expert said that they are just made that way and to get used to it. So, I am looking to trade it in soon. And our 2005 Camry vibrated if the wheels were not perfectly balance. This will be my last Toyota. They have gotten way too big and quality issues are popping up and they and really don't care.
