There is a problem with the auto fuel shut off where it will shut off to late and your tank will over flow on the 2003 models and late 2002 models. Toyota just released a tech bulletin to the dealerships that there is a problem with a check valve in the tank. Dealers are currently waiting for a special tool to extract the valve and put in a new one. My dealership told me they should have it within the next 6 weeks, it is coming from Japan.
