2018 Volvo S90

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 S90.

Body PASSENGER CARTransmission Automatic (S8)

The 2018 Volvo S90 is a midsize passenger car equipped with an eight‑speed automatic (S8) transmission and achieves an EPA rating of 22 mpg city, 31 mpg highway, and 25 mpg combined. Its drivetrain and chassis reflect Volvo’s contemporary engineering, while the fuel‑efficiency figures stand out as competitive for the segment. In terms of reliability, the model recorded just 12 owner complaints overall, with the electrical system identified as the most frequent issue and two recalls issued for the year. Positioned after a decade‑long complaint record that peaked at 39 complaints in 1998 and fell to a low of one in 1999, the 2018 S90 sits near the lower end of its historical complaint range, suggesting a comparatively steady reliability performance for researchers.

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 2018 Volvo S90 sits within the second generation, which began with the 2016 model year. The federal data shows that 2016 had zero complaints but two recalls, while the 2018 model year accumulated five complaints—primarily for electrical system and latch/lockage issues—with no reported crashes, fires, or recalls in the provided data. This suggests that while the 2018 model resolved the early recall triggers seen in 2016, it introduced a small number of minor electrical and latch concerns. Compared to the first generation (1997–1999), where complaints spiked to 39 in 1998 before dropping to 1 in 1999, the second generation has maintained a much lower complaint volume overall. The 2018 S90 appears to be a generally reliable year, but a prospective buyer should inspect the electrical system and door latches for any intermittent faults.
