Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 2001 Toyota Sienna shows 190 complaints, 2 recalls, and 0 investigations, which is a notable drop from the 381 complaints and 1 recall in 2000 and a decline from the peak years of 1998‑2000. Compared with the following two model years, complaints rise slightly to 207 in 2002 before falling to 116 in 2003, placing 2001 in a descending phase of the first‑generation trend. Recall activity remains low (2 recalls) and mirrors the modest level seen in 2000, while investigations disappear entirely after 2000. The top complaint areas for 2001 are Latches/Locks/Linkages (22), Structure (19), Engine & Engine Cooling (17), and Service Brakes, Hydraulic (12), as recorded in the federal data. Overall, the 2001 model year sits in a relatively favorable interval of lower complaint volume and no open investigations, suggesting it is a sound choice among used Siennas of this generation.
