The Toyota Sienna is one of Toyota’s longest-running nameplates. This minivan has been one of the top sellers in the segment for nearly 30 years, going up against other stalwarts like the Honda Odyssey and Chrysler’s Pacifica/Voyager pair. Although the Honda Odyssey sold more units in 2024, the Sienna is by far the best seller thus far into 2025, with over 68,000 models finding new homes in comparison to the Odyssey’s 65,544. Toyota is known for reliability, so those numbers make sense – but with over nearly three decades, no car is free from issues. When it comes to reliability, which Toyota Sienna generations come out on top?
