How reliable is the Toyota Sienna? What NHTSA's records show
We don't give the Sienna a reliability score. NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. Here is what's on file for model years 2010 on.

Every model year compared
Complaints rise with how many were sold and how long they've been on the road, so a newer or rarer year will show fewer. Compare years of the Sienna with each other.

Common questions
Is the Toyota Sienna reliable?
We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. What's on file for model years 2010 on: 1,998 owner complaints, 19 warranty extensions and 16 service campaigns Toyota filed, and 39 safety recalls. The model years with the most complaints are 2011 (614), 2012 (247), 2015 (233). Whether a known problem was fixed on one car is what its service records show.
What are the most common problems with the Toyota Sienna?
Across every model year since 2010, owners' complaints to NHTSA most often name body and structure (24%), airbags (17%), other or unspecified (14%). Toyota has filed 19 warranty extensions covering the Sienna, listed on this page.
Which Sienna model years have the most complaints?
2011 (614), 2012 (247), 2015 (233). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Sienna with each other rather than with other models.
Has Toyota extended the warranty on the Sienna?
Yes: brakes (model years 2017–2020); airbags (model years 2011–2014); doors, latches and locks (model years 2011–2018), and 16 more. A dealer does a covered repair for free within the extended time or mileage.
How do I check recalls on a Sienna?
Enter the car's 17-character VIN at nhtsa.gov/recalls. That answers for one vehicle; the 39 recalls listed here are for the model, and each covers only part of it.
