Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 Sienna.
The 2025 Toyota Sienna pairs its 36/36/36 mpg EPA rating with an Automatic (AV-S6) transmission, establishing a powertrain profile focused on consistent fuel efficiency across all drive cycles. Current reliability data registers 258 total owner complaints with seats identified as the top concern, alongside five recalls issued for this model year. When positioned against the model’s historical complaint spectrum spanning 1996 to 2020—a range bookended by just two complaints in 1997 and a peak of 2,062 in 2004—the 2025 iteration sits comfortably below the line’s historical volatility threshold, suggesting a maturation of the production cycle rather than a recurrence of the quality spikes seen in earlier generations.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2025 Toyota Sienna sits at the leading edge of the current hybrid-only generation, and the federal record for the prior generation (through 2020) shows a clear downward arc in complaints — from peaks of 2,062 (2004) and 1,130 (2005) down to just 36 complaints by 2020, with recalls similarly tapering to 2 that year. Against that improving trend, the 2025 data marks a notable reversal: the top complaint area, Seats, alone accounts for 188 complaints — more than five times the total complaints recorded for 2020 — with an additional 15 "Unknown or Other" complaints and smaller clusters in Visibility (9) and Structure (8). Crash complaints are minimal at 2 and fire complaints are zero, which is reassuring on the safety front, but the concentration in a single category suggests a specific, systemic issue rather than scattered defects. The federal record does not specify a root cause for the seat complaints, so buyers should verify whether a related TSB or recall has been issued before purchase. Given the sharp uptick in seat-related complaints relative to the tail end of the prior generation, the 2025 Sienna is a year to approach with caution — confirm the seat issue has been diagnosed and, if applicable, remedied before committing.
