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; 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 Scion xA recorded 14 complaints, 2 recalls, and 40 technical service bulletins. Across the generation, there is a clear upward trend in issues, with complaints rising to 40 in 2005 and peaking at 71 in 2006, while recalls increased from 2 in 2004 to 6 in 2006. As the earliest year in this record, 2004 sits at the bottom of this escalation arc, implying a more stable initial release compared to later models. The most frequent complaint area for the 2004 model was Engine & Engine Cooling with three reports, though the data does not specify the root cause; additionally, there were two crash complaints and one fire complaint. Because it has the lowest volume of complaints and recalls relative to the 2005 and 2006 model years, this is a good year to buy.
