Toyota Sienna 1998–2026
Summary
- 29 model years in 4 generations, 9,324 owner complaints in total.
- Within their own generation, 2000, 2004 and 2011 drew the most complaints in the first three years.
- 2001, 2002, 2006, 2008, 2016 and 2023 drew the fewest complaints of their generation over the same span.
- These are complaint counts, not failure rates: they are not divided by how many cars were sold, because no public source reports U.S. sales by model year.
- Half of the complaints that give a mileage were filed by 68,000 miles (5,996 of them give one).
- Owners reported 453 crashes, 81 fires, 697 injuries and 11 deaths across these model years.
- 59 recalls and 15 federal investigations cover these model years; 1 investigation is still open.
1998–2003
Each year is counted over the same span: complaints received up to two calendar years after its model year. A year is compared only when that span is over and it holds at least 50 complaints. Median of the comparable years: 99.

Every model year
A model year gets its own page when four sources cover it, it holds at least 50 complaints, and it either compares with the other years of its generation or shows one system in 40% or more of the complaints that name a component. The rest are listed here with their figures.

Service bulletins
Toyota issued 6,143 service bulletins covering these model years, most often about equipment.
A bulletin tells dealers how to fix a known condition. It is not a recall and not a defect finding. Most bulletins cover several model years at once, so a bulletin listed here may not be specific to one year. The number of bulletins tracks how long and how widely a model was sold, so it is not a measure of reliability.

How to read this page
Complaint counts are not failure rates. A model that sells more cars draws more complaints, and owners file more after news coverage or a recall. That is why years are compared only with other years of the same generation, over the same span, and never with other models.
