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 2014 Toyota Sienna recorded 162 federal complaints, 6 recalls, 1 investigation and 357 TSBs. That complaint level is lower than the 2012 peak of 247 and comparable to the 2013 (182) and 2015 (228) figures, reflecting the continued downward trend after the early‑2000s spike. Recalls in 2014 are in line with the 5‑10 range seen in recent years, and the single investigation matches the pattern of limited new probes observed from 2011 through 2018. The top complaint category, Structure, accounted for 36 of the 162 reports, while Fire complaints were only 2, indicating modest concerns typical for this generation. Consequently, the 2014 model presents a low‑to‑moderate risk profile and is generally a sound used‑vehicle option, provided that any structure‑related service actions have been completed.
