I've owned several Toyota vehicles and currently own a Tundra, also. None of them have ever given me the problems this Sienna has. Since day one, we've had a number of problems with the van, including a faulty power door, door latches, brakes, etc. The only way to get Toyota to fix most of this stuff was to threaten a lawsuit. Oh what a feeling. Also, gas mileage is poor at best. We've never been able to break 20mpg with this van, no matter what grade of fuel we use.
Well, the cupholders work and are a nice design. The van is fairly easy to re-configure if you need to haul stuff.
BETTER TIRES. These Firestone tires are noisy and ride terrible. Build quality of this van is poor at best. Please Toyota... Please hire a decent QC department. This van should have never left the factory. Thumbs down!
