How reliable is the Toyota Sienna Hybrid? What NHTSA's records show
We don't give the Sienna Hybrid 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 2021 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 Hybrid with each other.

Common questions
Is the Toyota Sienna Hybrid 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 2021 on: 483 owner complaints, 3 warranty extensions and 8 service campaigns Toyota filed, and 8 safety recalls. The model years with the most complaints are 2025 (267), 2024 (69), 2023 (68). 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 Hybrid?
Across every model year since 2021, owners' complaints to NHTSA most often name seats (48%), other or unspecified (13%), brakes (11%). Toyota has filed 3 warranty extensions covering the Sienna Hybrid, listed on this page.
Which Sienna Hybrid model years have the most complaints?
2025 (267), 2024 (69), 2023 (68). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Sienna Hybrid with each other rather than with other models.

Yes: electrical system (model years 2021–2024); engine (model years 2021); engine and cooling (model years 2021–2023). A dealer does a covered repair for free within the extended time or mileage.
