2015 Toyota Sienna

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Sienna.

Body VANTransmission Automatic (S6)

The 2015 Toyota Sienna is a van fitted with an Automatic (S6) transmission and a 6.4-quart 0W-20 oil specification, carrying EPA fuel-economy ratings of 18/25/21 mpg. Owner records show 227 total complaints, with structure ranking as the top concern, alongside six recalls. Within the broader 1996–2020 complaint history, which peaks at 2,062 reports for the 2004 model and bottoms at two for 1997, the 2015’s tally sits far below that high-water mark. That placement signals a comparatively modest complaint burden for researchers examining long-term reliability trends.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 6.4 qt of 0W-20 engine oil, 75W-85 · GL-5 in the differential, SAE J1703 · DOT 3 brake fluid. Torque the oil drain plug to 10.0 ft-lbs. The firing order is 1-2-3-4-5-6. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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 2015 Toyota Sienna sits squarely in the middle of the third generation (roughly 2011–2020), and its federal record is moderate rather than problematic: 227 complaints, 6 recalls, 0 open investigations, and 347 technical service bulletins. Within the generation's arc, the 2015 model year actually shows a slight uptick from the cleaner 2013 (182) and 2014 (162) model years, while sitting well below the launch-year 2011 (610 complaints, 14 recalls) — suggesting that 2015 reflects a mid-cycle plateau rather than a deterioration. The top complaint categories for 2015 are led by Structure (49), Unknown or Other (29), and Electrical System (21), with Power Train a distant fourth at 9; the 17 crash and 7 fire complaints are notable but the data does not specify a unifying root cause. Compared to the troublesome 2004–2006 second-generation years (which peaked at 2,062 complaints and 12 recalls), 2015 looks far cleaner, and the trajectory afterward (2016 at 75, 2018 at 69, 2019 at 45) shows continued improvement as the platform aged. **Bottom line:** 2015 is a defensible used buy — not the absolute sweet spot of the generation (2013, 2014, or 2016 are statistically quieter) — but the absence of investigations and the modest recall count argue against red flags, making it a reasonable choice provided you verify recall completion and inspect the structure and electrical systems.
