I also bought a 2004 Sienna CE I purchased new in 2003. One problem I ran into is that its gas line broke right under neath the drive seat - for no aparent reason!!! It was so dangerous. My mechanics said I should complain to Toyota since it just made no sense to have such a fatal flaw. It probably qualify for a recall. I'd be open to suggestions. Another problem is it recently became incapable of starting cold. Last year it happened once and I added some gas treatment. Either because of the warm weather (in DC) or the gas treatment worked, it didn't happen until yesterday. We're now in 20s F. My Sienna CE is now grounded. I don't know what to do. Forecast says the cold front will be here for another week... oh my! Otherwise, it's a good car.
