2015 Scion xB

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 xB.

Transmission Automatic (S4)

The 2015 Scion xB is a boxy five-door wagon powered by a four-cylinder engine, holding 4.5 quarts of oil with a recommended viscosity of 0W-20 or 5W-20 meeting API standards, and paired with a four-speed automatic transmission; it achieves EPA fuel economy ratings of 22 mpg city, 27 mpg highway, and 24 mpg combined. This model year recorded only six total owner complaints across all categories, with engine-related issues being the most frequently cited concern, and it carried three separate recalls. When placed within the model's complaint history spanning 2002 to 2015, the 2015 xB sits at the opposite end of the spectrum from the 2008 model year—which generated 339 complaints, the highest on record—having dropped to nearly minimal complaint levels comparable to the 2003 model's single complaint. This dramatic decline in reported issues suggests the 2015 xB represents one of the most reliable iterations of the model, though the persistent engine complaint category indicates owners should remain attentive to maintenance intervals.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 4.5 qt of 0W-20 / 5W-20 API engine oil, DOT 3 brake fluid. Torque the oil drain plug to 18.0 ft-lbs. The firing order is 1-3-4-2. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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 2015 Scion xB sits at the end of a clear improvement arc, with federal complaints falling steadily from the 2008 second-generation peak of 339 down to just 6 in 2015—the lowest complaint count in the entire 2002-2015 record. Recalls follow a similar downward trend, dropping from 11 in 2006 and 2009 to 3 in 2015, matching the low levels seen in 2013 and 2014, while the single investigation is consistent with the 2008-2014 record. Technical service bulletins also declined to 121 in 2015 from 149 in 2014, though they remain elevated compared with the 2002-2007 period. The top complaint categories—engine, air bags/structure/service brakes, service brakes, and electrical system—each logged only one complaint, so the data does not indicate a recurring defect pattern; the two crash complaints and one fire complaint are likewise too few to establish a cause. Compared with the troubled 2006 and 2008 model years and even the 2012-2014 period, 2015 shows the most settled federal record in the model's history. For a used-car buyer, that makes the 2015 xB the statistically safest bet of this generation.
