2007 Subaru Legacy — 3.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 Legacy 3.0L.

Body PASSENGER CAREngine 3.0LTransmission Automatic (S4)

The 2007 Subaru Legacy is a passenger car equipped with a 3.0L engine and a four-speed automatic transmission, returning EPA figures of 20 mpg city and 28 mpg highway with routine service calling for 4.4 quarts of 5W-30 API oil. Across the broader Legacy complaint record spanning 1990 through 2025, this model year's 33 owner complaints and nine recalls—centered primarily on air bags—place it well below the 1995 high-water mark of 216 complaints, indicating moderate but not exceptional reliability for the era. That relatively middling standing means a prospective owner or researcher should weigh recall resolution and air-bag service history carefully, even though the 2007 is far from the worst offender in the nameplate's three-decade track record.

This engine holds 4.4 qt of 5W-30 API engine oil, DOT 3 brake fluid. Torque lug nuts to 74-89 ft-lbs, the oil drain plug to 33.0 ft-lbs. The firing order is 1-3-2-4. 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 at 3,000 mi; spark plugs every 60,000 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 2007 Subaru Legacy sits at the nadir of a distinct complaint arc within its generation, dropping sharply from 182 complaints in 2005 and 87 in 2006 down to just 33 in the target year. However, while consumer complaints reached a generation-low in 2007, the recall count remained steady at 9—unchanged from 2005—suggesting underlying regulatory concerns persisted despite improved initial reliability. For 2007 specifically, Air Bags lead the complaint areas with 9 reports, followed by the Engine with 4, though the data does not specify the root causes for these categories; notably, the model also logged 4 fire complaints and 1 crash complaint. Following 2007, complaints doubled to 65 in 2008 and eventually spiked back to 167 by 2011, indicating that 2007's low-complaint status was a brief improvement rather than a permanent resolution. Consequently, the 2007 model year is a comparatively strong choice within this generation due to its remarkably low complaint volume, but buyers must verify that all 9 safety recalls—especially those involving airbags and the engine—have been properly addressed.
