2023 Toyota Sienna

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Sienna.

Transmission Automatic (AV-S6)

The 2023 Toyota Sienna is a minivan built on Toyota's platform, equipped with an automatic transmission (AV-S6) and requiring 4.8 quarts of 0W-16 or 0W-20 engine oil for maintenance. The vehicle achieves an EPA-estimated fuel economy of 36 mpg across city, highway, and combined ratings, making it notably efficient in its class. With only 62 total owner complaints recorded—dwarfed by the model's historical peak of 2,062 complaints in 2004 and far above its lowest complaint year of 1997 with just 2—the 2023 Sienna represents one of the most reliable iterations in the model's history, supported by just one recall.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs at 120,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The provided year-by-year federal record stops at 2020 and includes no entry for 2023, so a direct comparison of 2023 against adjacent model years on total complaints, recalls, or investigations is not possible from this data. The generation's arc is clear, however: two pronounced problem periods occurred in 2004–2006, when annual complaints ranged from 1,016 to 2,062 and recalls hit 10–12 per year, and in 2011, with 610 complaints and 14 recalls; after that, the trend moved steadily downward to a low of 36 complaints and 2 recalls by 2020. For 2023 itself, the available data points to service brakes as the top complaint area with 21 reports, followed by unknown/other at 14, visibility/wiper at 6, and electrical system at 4, along with 8 crash complaints and 0 fire complaints, though the data does not specify underlying causes. That profile sits in the low-complaint phase of the generation, but the missing full-year federal totals for 2023 leave its complete picture unresolved. Concrete takeaway: 2023 appears to be a relatively calm year within this Sienna generation and is a defensible used buy, provided you confirm no open recalls and inspect service records for brake and visibility items, since the federal record is incomplete for this model year.
