Toyota Sienna Generations
The Sienna has 3 generations available in North American markets. A generation is a group of model years where few, if any, changes were made to the vehicle which means their model years tend to break in similar ways.
The 2nd generation (2004—2010) has been the least reliable.

Tell Us What's Wrong With Your Toyota
The best way to find out what's wrong with a vehicle is from the people who drive them. Not only do owner complaints help us rank vehicles by reliability, but they're often used to spark class-action lawsuits and warranty extensions. Plus, they're a great way to vent.
