I own a 1998 Sienna. I guess the good news is that this is a "pre-sludge" era Toyota - but the sliding door button jamming is a serious safety problem and a major pain in the backside. It used to happen only once a month or so - now every day. These buttons get stuck in - if it happens when the door is open, it often cannot be closed! (which means you cannot go anywhere for the 5-20 minutes it takes for this button to pop out on its own). If it happens when the door is closed, it cannot be opened from the inside or outside, meaning passengers have to climb up and over to get out! I love the head and legroom; but I have a terrible rattle in the right sliding door, the rear seat belts lock up easily on anyone bigger than a small women, and I had to replace my tires at 30K miles due to mis-alignment wear. I'm terribly disappointed in Toyota.
