Toyota Sienna Reliability

You won't find Toyota Sienna reliability information like this anywhere else. Actual repair frequencies, not just vague dots. So you can tell how much the Toyota Sienna truly differs from competing car models in reliability.

These stats have been promptly updated four times a year, to much more closely track Toyota Sienna reliability as the cars age. Others tell you how reliable the Toyota Sienna was a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the Toyota Sienna has been recently.
