2004 Scion XB

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 XB.

Transmission Automatic 4-spd

The 2004 Scion XB, noted for its 4‑quart engine oil capacity and 5W‑30 API viscosity requirement, pairs that with an automatic four‑speed transmission and delivers EPA‑rated fuel economy of 26/31/28 mpg. In its first year of ownership it generated 37 total complaints, with air‑bag issues leading the list and six recalls issued. Compared with the broader 2002‑2015 Scion XB complaint history—where the lowest point was just one complaint in 2003 and the peak reached 339 in 2008—the 2004 model sits near the favorable end of the spectrum, indicating a relatively reliable start for the nameplate.

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.

In 2002 and 2003 the Scion XB recorded zero and one complaint respectively, with one and two recalls. Complaints jumped to 37 in 2004, accompanied by six recalls and 48 technical service bulletins. After 2004 complaint volumes continued to rise, reaching 92 in 2005, 253 in 2006, and peaking at 339 in 2008 before declining to single‑digit levels by 2015. Recall counts followed a similar pattern, increasing from six in 2004 to a high of eleven in 2006 and 2009, then gradually falling to three per year from 2013 onward. Given that 2004’s complaint and recall figures are modest compared with the later peak years but higher than the inaugural 2002‑2003 models, it represents a middle‑of‑the‑road option for a used buyer seeking relatively low reported issues.
