Is the Subaru Legacy reliable?

The Subaru Legacy is generally considered a dependable choice in the midsize sedan segment, especially for buyers who value all-wheel drive and safety. Across generations, most owners report solid reliability and reasonable ownership costs, but reliability varies by year, drivetrain, and how well the vehicle has been maintained.

Reliability at a glance

This section provides a high-level read on how the Legacy has performed in reliability surveys, consumer reviews, and common ownership experiences. It highlights strengths and the main caveats to consider when evaluating a used or new Legacy.

• Standard all-wheel drive across most trims contributes to solid performance in adverse weather and is a feature many buyers equate with long-term reliability.


• Overall maintenance costs are generally reasonable for a midsize sedan, though key repairs (engine work on older 2.5-liter engines and CVT-related issues) can be expensive.


• Reliability tends to vary by generation and engine type; earlier EJ-series 2.5-liter engines have a history of head gasket leaks and oil consumption in some applications, while newer engines and CVTs have shown improved durability with proper maintenance.


• Resale value remains relatively strong, helping to offset ownership costs for many buyers and reinforcing the perception of reliability.

In the sections that follow, this article breaks down reliability by era, highlights common issues to watch for, and offers guidance for choosing a well-maintained Legacy.

Common reliability concerns by generation

Across the lineup, a few issues recur. Here are the typical trouble spots to consider when evaluating a used Legacy and to discuss with a mechanic during a pre-purchase inspection.

• Older 2.5-liter EJ engines: head gasket leaks and oil consumption have been reported in various years, particularly in some earlier generations. A well-documented service history helps mitigate surprises.


• Oil consumption: certain 2.5L engines have been known to burn oil at higher-than-average rates; check for a consistent oil-change schedule and look for signs of regular maintenance.


• Drivetrain and transmissions: CVT-equipped models (Lineartronic CVT) have generally improved with newer designs and updates, but some earlier CVTs required maintenance or replacement, so verify the transmission’s service history and any recall or warranty coverage.


• Timing belt maintenance: many Legacy engines use a timing belt that requires replacement at manufacturer-recommended intervals; neglecting this can lead to significant engine damage.


• Suspension and steering components: front struts, ball joints, wheel bearings, and related components commonly wear with mileage and can affect ride quality and handling.

These issues are not universal, and many Legacy owners experience trouble-free operation with regular maintenance and a well-documented service history.

Model-year reliability snapshot

Reliability ratings and owner experiences vary by year and generation. The following qualitative guide summarizes what tends to be true across eras, while underscoring the importance of model-year-specific data from Consumer Reports, J.D. Power, and owner forums.

• Most recent model years (roughly 2014–2023): generally solid reliability for a midsize sedan with standard all-wheel drive; ongoing improvements to the CVT and engine efficiency have reduced some older concerns, though proper maintenance remains essential.


• Mid-2010s: strong overall reliability with good engine performance and improved CVT behavior; ensure the vehicle has a clean service history and that recall work has been completed.


• Early to mid-2000s: reliability can be more variable; some engines exhibited head gasket and oil consumption concerns, so verify maintenance records and consider a thorough pre-purchase inspection.

Because reliability can differ significantly from one example to another, prospective buyers should consult model-year-specific reliability data and obtain a professional pre-purchase inspection before buying.

Maximizing reliability: buying tips and maintenance guidance

To maximize the long-term reliability of a Subaru Legacy, buyers and owners should follow a diligent maintenance routine and make informed purchasing choices. The following list outlines practical steps and checks.

• Get a thorough pre-purchase inspection (PPI) by a technician familiar with Subarus, focusing on the engine’s head gasket, oil leaks, CVT condition, and timing belt status where applicable.


• Review maintenance history for oil changes, coolant flushes, timing belt replacement (if applicable), CVT service, and brake work; verify that recalls and service campaigns have been completed.


• Inspect for signs of oil consumption or burning oil, and check for coolant leaks around the radiator, hoses, and engine gaskets.


• Evaluate the CVT behavior: smooth engagement, absence of shuddering on acceleration, and proper transmission fluid condition and service intervals; address any transmission fluid leaks or warnings promptly.


• Test drive in varied conditions to assess handling, braking, and ride quality, paying attention to unusual noises, vibrations, or pulling that might indicate suspension or drivetrain wear.


• Check for corrosion and rust, particularly in areas with harsh winters or road salt exposure, as structural integrity can affect safety and longevity.

By prioritizing a careful purchase and consistent maintenance, the Legacy can deliver reliable service and steady ownership costs over many miles.

Bottom line

Overall, the Subaru Legacy is regarded as a reliable option in the midsize-sedan category, especially for drivers who want standard all-wheel drive and safety features. Reliability tends to be strong in newer generations, with ongoing improvements to transmission technology and engine design. However, older 2.5-liter engines and some CVT configurations have historically presented maintenance and repair challenges. The key to strong reliability is selecting a well-documented model year and staying current with scheduled maintenance.

Summary

The Legacy offers dependable performance for most owners, with a favorable balance of safety, all-wheel drive capability, and resale value. Reliability varies by generation and maintenance history, so prospective buyers should seek a well-documented vehicle, prioritize models with updated CVTs and updated engines, and insist on a thorough pre-purchase inspection. With attentive maintenance, many Legacy owners enjoy trouble-free operation well beyond the 100,000-mile mark.

Does the Subaru Legacy last long?

Yes, the Subaru Legacy can last a long time, with many models easily exceeding 200,000 miles with proper maintenance. A key factor in its longevity is regular upkeep, including consistent oil changes and servicing, while avoiding vehicles with incomplete service records or visible rust. Subaru notes that 94% of Legacies sold in the past 10 years are still on the road, highlighting the model's strong reliability.

Factors influencing longevity

• Regular maintenance: Consistent oil changes, brake replacements, and timing belt or CVT servicing are crucial for long-term durability.
• Complete service history: Vehicles with complete and documented service records are a safer bet, as they are more likely to have had the necessary upkeep.
• Avoiding red flags: Be cautious of models with unusual engine noises, warning lights, or poorly functioning CVTs, as these can signal costly future repairs. 

How to maximize your Legacy's lifespan

• Use OEM parts: When repairs are needed, using Original Equipment Manufacturer (OEM) parts ensures a proper fit and quality, which can lead to longer-lasting components. 
• Use certified service centers: Having your vehicle serviced by Subaru-trained technicians using advanced diagnostics and OEM parts can help protect your investment. 
• Drive regularly: The Subaru flat boxer engine works best when driven regularly.
