I have a 2004 ES330 with the same vibration problem you guys are describing. After MANY attempts to fix the problem at the dealers, the dealer is now lying to me saying they dont feel the vibration anymore. I went to arbitration and found out 2 days ago, that I lost. The arbitrators say i failed to show the problem. It is a slight vibration, but the driver can feel it, and I hate that I spent so much money on this piece of .... I guess this means court now, so if anyone can help me....Id greatly appreciate it.
