I live in Rustic Village with a supportive apartment program, which owns a Toyota Sienna, and I have ridden in it before, and after a straight-away stop, with out any traffic in front of you, the van will switch gears very quickly, when you are barely away from the traffic light 10 feet or less. I understand and know that it needs to switch gears, but why so quickly. We think that it's a V6, but the stupid thing drives and acts like a little V4, and the engine's transmission grinds and squeaks, just like a tiny V4 sports car. I also think that the van is a piece of garbage, which could also be part of the problem. With me being in that darn Sienna I'm not very proud or impressed with Toyota because of their recalls and because of my van issues.
