2023 Subaru Legacy

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Legacy.

The 2023 Subaru Legacy calls for 4.8 quarts of 0W-20 engine oil and carries 10 owner complaints and two recalls on record, with the leading complaint area categorized as “Unknown Or Other.” Within the model’s 1990–2025 complaint history—a band that stretches from 216 grievances at its 1995 peak down to six in 2025—this model year sits near the lower bound. That placement makes it one of the lower-complaint iterations in the Legacy’s multi-decade span.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 6,000 mi; spark plugs every 60,000 mi; coolant every 6,000 mi. The big-interval services (every 6,000 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 2023 Subaru Legacy sits at a notably low point in the generation's complaint arc, with only 10 complaints, 2 recalls, and 0 investigations recorded federally—down sharply from the 31 and 32 complaints seen in 2021 and 2022, and a fraction of the 118–159 complaints logged in the early years of this generation (2015–2017). Recall activity has also stabilized at a modest 2, consistent with the lighter recall cadence Subaru has maintained on this model since 2017 (2–3 per year) and a clear retreat from the 10–18 recalls issued in the 2010–2014 era. The 301 TSBs are likewise lower than the 437 and 359 posted in 2021 and 2022, though still substantial in absolute terms, and likely reflect the broader refinement of the platform as it approached the end of its production run. Of the 10 complaints, the leading areas are unspecified ("Unknown or Other," 3) followed by Forward Collision Avoidance and Air Bags (2 each), and 2 of the 10 complaints involve crashes—no fire complaints are on record, though the data does not specify a root cause for any cluster. As a used-vehicle candidate, the 2023 is a defensible pick on the federal record: low complaint volume, no open investigations, and a downward trend across the back half of the generation suggest it is one of the cleaner Legacy model years to consider, provided a pre-purchase inspection confirms the specific safety-system components have not been flagged for service.
