Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 5,000 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 2004 Toyota Sienna sits at the highest point of the federal record, logging 2,062 complaints, 10 recalls, and 10 investigations—figures that dwarf 2003's 116 complaints, 1 recall, and 0 investigations, and exceed 2005's 1,130 complaints and 6 investigations. Across the year-by-year arc, activity remains comparatively low from 1996 through 2003, spikes sharply in 2004, and then trends downward through 2006 while staying well above the pre-2004 baseline. The 2004 model carries the heaviest concentration of owner reports, led by 722 structure complaints, 150 latches/locks/linkages complaints, 142 combined structure/latches complaints, and 105 steering complaints, plus 51 crash-related and 8 fire-related complaints. Because the data identifies complaint categories but does not specify root causes, it cannot say whether one defect or several issues produced the spike. Given that 2004 is the statistical peak for complaints, recalls, and investigations in this record, it is a riskier used-minivan purchase than adjacent years, and buyers should verify that all applicable recalls are closed and budget for the possibility of structural, steering, and latching repairs.
