2021 Volvo XC90

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 XC90.

Transmission Automatic (S8)

The 2021 Volvo XC90 is defined by a tight set of servicing and efficiency figures—a 6.4-quart 0W-20 oil capacity, an eight-speed automatic transmission, and EPA ratings of 19 mpg city, 28 mpg highway, and 22 mpg combined—paired with a comparatively quiet reliability profile. Owner-reported complaints against the model year total just 17, led by electrical system, unknown/other, and back-over prevention concerns, with five recalls also on file. Plotted against the XC90's 2003–2015 complaint history—which peaked at 462 in 2004 and bottomed out at 3 in 2012—the 2021 model year lands firmly on the modern, well-settled end of the curve, a useful reference point for anyone tracking the nameplate's long-term reliability trajectory.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 60,000 mi; coolant every 10,000 mi. The big-interval services (every 10,000 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 first-generation XC90 (2003–2015) shows a clear arc: complaints spiked at 462 in 2004, then fell sharply to single digits by 2009 and hit zero in 2015, while recalls also declined from a high of 6 to just 1 in the final year. The 2021 model, though from a later generation, continues this low-complaint pattern with only 4 total complaints and no reported crashes or fires. Without recall or TSB data for 2021, a direct comparison is incomplete, but the complaint count is dramatically lower than the early troubled years. This suggests the 2021 XC90 is a solid choice, reflecting the mature, reliable phase seen at the end of the earlier generation.
