This is our second Sienna; our 1998 was fine. We've had the 2007 model for two years now, and it's had a lot of trouble with the run-flat tires. A couple of flats, and the air-pressure warning light comes on way too often. Today I took another flat to the dealer; the service department said "you're not supposed to just replace one of these at a time -- we should do all four. Otherwise, if the differential fails or the transmission fails, Toyota won't cover it under warranty." So -- throw away 3 good tires (only half worn) and spend $1000 on new run-flats, or Toyota won't honor the warranty? Ridiculous. Also, this van gets at least 20% worse mileage than our old one. Disappointing!
Good DVD player. Like the power outlet in the back -- my kids can plug in their Playstation for long trips. Decent seats. Good flexibility in folding/storing seats. AWD is surefooted on snow.
It's too bad that Toyota still does not make a Sienna hybrid; the mileage is terrible, and should be much better. The decision to put run-flat tires on the AWD version seems like a mistake -- apparently made because they had no room for a spare, but the result is wasteful or potentially damaging.
