I still have the 2004 Toyota Sienna XLE Limited AWD van. It's been a solid performer since day 1. It's quiet, powerful, dependable, and comfortable on long trips. We live in New England, and it's great in the winter. We have the 7-seat option, so there is plenty of room. I have had a few service items, some expected, some not. Problem areas: Oxygen and Air/Fuel sensors, inconsistent electrical problems with doors & windows, brake rotors/disks, rear wheel bearings.
Comfortable, stable in bad weather driving conditions. Air bags and curtains. I did not think I'd like the automatic doors, but they have been very useful. Climate controls in front and rear.
Parking sensor warning lights need better placement, Run-flat tires need better monitoring system, the alloy wheels are showing some finish flaking.
