2002 Subaru Legacy — 3.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 Legacy 3.0L.

Body PASSENGER CAREngine 3.0LTransmission Manual 5-spd

The 2002 Subaru Legacy 3.0L is a mid‑size passenger car powered by a naturally aspirated 3.0‑liter engine that requires 4.2 quarts of 5W‑30 API oil and is paired with a manual 5‑speed transmission, delivering EPA ratings of 19 mpg city, 25 mpg highway, and 21 mpg combined. Its moderate engine displacement and robust cooling demands place it in the “Engine & Engine Cooling” complaint category, the top concern among owners in that model year, while the vehicle’s overall complaint count—59 in total—remains well below the series’ peak of 216 complaints in 1995 and far above the recent low of six in 2025. This positions the 2002 Legacy as a model with respectable reliability relative to its peers, though it still reflects the brand’s historical challenges with engine cooling systems.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 3,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 2002 model year represents a notable low point in consumer complaints within its generation, recording only 59 complaints compared to 81 in 2001 and 103 in 2000, while sitting just before a significant escalation that saw recalls jump from 5 in 2002 to 15 in 2003 and 11 in 2004. This year falls within a downward trend of reported issues that bottoms out in 2004 at 49 complaints, preceding a dramatic spike to 182 complaints in 2005, suggesting 2002 captures the platform in a relatively stable phase before increased manufacturer action. Technical Service Bulletins remained elevated at 150, slightly below 2001's 155 but significantly higher than pre-2000 levels, indicating ongoing service activity despite lower consumer reporting. The primary complaint categories for 2002 focus on Engine & Engine Cooling (9 reports), with additional reports distributed across fuel and brake systems, though the data does not specify root causes for these patterns. With only 6 crash-related and 1 fire-related complaint on file, and investigations at zero, the federal record positions 2002 as a comparatively quiet year before the documented turbulence of 2003-2005. This makes 2002 an attractive purchase candidate within this generation, offering lower reported complaint volumes than adjacent years while avoiding the recall surge that immediately followed, provided prospective buyers verify that the five recorded recalls have been addressed.
