GarageCalc What the data says
Seats accounts for about 65% of this year's Toyota Sienna Hybrid complaints. That is a strong concentration, the kind that usually points to a specific known issue rather than general wear.
The 2025 model year contributes 184 complaints (72%). A cluster this concentrated on a fresh model year is worth checking against open recalls before buying.
Complaints are up sharply year over year, 56 to 257 (+359%), in a market that rose about 2%. Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Toyota Sienna Hybrids are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
