2018 Toyota Sienna

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Sienna.

Body VANTransmission Automatic (S8)

The 2018 Toyota Sienna is a van propelled by an S8 automatic transmission and an engine requiring 0W-20 oil with a capacity of 5.7 to 5.8, delivering an EPA-estimated 19 city and 27 highway mpg. Although its 69 owner complaints—primarily focused on the power train—along with 7 recalls warrant attention, this model year occupies a moderate middle ground within the Sienna's broader 1996-2020 reliability timeline. With historical complaint figures swinging from a low of just 2 in 1997 to a peak of 2062 in 2004, the 2018's relatively modest tally means it stands as a reasonably stable, if imperfect, option for researchers evaluating the platform's long-term dependability.

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 every 60,000 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 2018 Toyota Sienna sits near the tail end of the third generation (2011–2020) and, based on federal data, represents a low point in complaints for the generation, with only 69 total complaints — far fewer than the 610 seen in 2011 or the 152 in 2017. Recalls for 2018 total 7, which is consistent with the 6–7 range of adjacent years (2017 had 10, 2019 had 7), and there are zero investigations, matching the clean record of 2016 and 2019. Notably, the 2018 model has 300 Technical Service Bulletins (TSBs), a spike compared to 2017’s 259 and 2019’s 191; the data does not specify root causes, but this could indicate that Toyota issued many proactive service advisories without a corresponding rise in owner complaints. The top complaint area is the powertrain (13 reports), and there are only 5 crash complaints and no fire complaints, suggesting no widespread safety crisis. Overall, the 2018 Sienna shows a strong reliability profile within its generation, with low complaint volume and no investigations, making it a good year to buy.
