I'm interested in reading the replies here, as I am hoping to get a Sienna soon. I currently have a 2003 Honda Odyssey with 138,000 miles, and while I love driving this van, it has had a number of issues that lead me to want to go in another direction next time. I was one of the unlucky ones who had a model with transmission problems. That cost us $2000 to fix. I also have a sliding door that is messed up and doesn't always open/close. I was quoted $800 to fix it. We seem to need brake work often and the rest is mainly a lot of wear and tear--seatbelts that no longer retract, screws that fell out so trim won't stay on (inside), A/C that doesn't do better than kind of cool, visor that will swing around and bonk me in the head but can't be tightened (quoted $100+ to fix), and things like that. My dh doesn't worry about the wear and tear stuff but I hate it. Our van looks like an old motel room that desperately needs an update. In its defense, it has hauled around my 3 girls and their friends in comfort, has a nice DVD system with wireless headphones, and can hold tons of stuff while still carrying 6 people. I love that the back seat folds down seamlessly but I do like the improved models, Sienna included, that allow you to put down only one side of the rear seat. That would work much better for my family.
