Our Sienna has been virtually trouble-free, and we've also experienced an accident. The Sienna did an admirable job of protecting everyone, and the ALR rear seatbelts held the kids' car seats tight during the wreck. Still, I dislike this van. I find the Sienna dreadfully uncomfortable. The front seats are mushy and offer virtually no support. The cargo space behind the third-row seat is not terribly good, and I wish the Toyota had the same disappearing third-row seat as the Honda does.
