How long will a Subaru Legacy last?

Across generations, a Subaru Legacy can typically reach 200,000 miles or more with diligent maintenance; many owners report 250,000–300,000 miles, and some exceed 350,000 miles. The exact lifespan depends on the model year, driving conditions, and how well the car is cared for over time.

What affects longevity

Several factors determine how long a Legacy will stay on the road. Below is a practical overview of the most influential elements.

• Maintenance discipline and adherence to scheduled services


• Engine and drivetrain design of the generation (older EJ engines vs. newer FB/FA engines)


• Transmission type and care (manual vs. Continuously Variable Transmission, or CVT)


• Driving conditions (lots of short trips, heavy stop-and-go, or long highway commutes)


• Climate and exposure to harsh elements (extreme cold, heat, road salt, rust)


• Quality of parts and quality of repairs performed over the vehicle’s life


• Avoidance of major accidents and timely recalls/updates


• Overall vehicle design health in the chosen model year (e.g., recall history, known trouble spots)

In short, longevity hinges on consistent upkeep, sensible use, and choosing a well-maintained example from a generation with robust reliability characteristics.

Generation-by-generation durability

EJ-powered Legacy (roughly 1990s to early 2010s)

Many Legacy models in the EJ era rely on timing belts in several engines and are known for substantial longevity when the belts are changed at recommended intervals, along with regular cooling system and head gasket maintenance. Head gasket failures were a more common concern on some EJ variants, especially as miles accumulate, but proactive maintenance can dramatically extend life. Overall, these generations can still accumulate very high mileage when properly serviced.

FB/FA-powered Legacy (roughly 2010s onward)

Modern Legacy models use the FB/FA family with timing chains in many configurations and, in recent years, a CVT transmission. Chains generally reduce the risk of a belt-break failure, but chain-related issues and CVT wear require attentive maintenance, especially at higher mileages. The latest generations have benefited from improved manufacturing and electronics, contributing to strong long-term reliability when owners follow maintenance schedules.

Maintenance essentials to maximize lifespan

Keeping a Legacy on the road for as long as possible comes down to disciplined, preventive maintenance. The following checklist covers the basics that have the biggest payoff for longevity.

• Regular oil changes with the recommended weight and type (synthetic preferred for many models), typically every 5,000–7,500 miles depending on usage and manual guidance


• Cooling system service, including coolant replacement and inspection of hoses, radiator, and thermostat at recommended intervals


• Transmission/CVT care: follow the manual for fluid changes and inspections; neglecting CVT fluid can shorten transmission life


• Timing belt (if applicable) or timing chain inspection: replace belts at factory-recommended intervals; chains should be inspected for tension and wear


• Spark plugs and ignition components: replace at manufacturer intervals to maintain efficiency and prevent misfires


• Brake system maintenance: regular pad/rotor checks and brake fluid flushes as needed


• Air and cabin air filters: replace on schedule to maintain engine efficiency and interior air quality


• Battery health and electrical system checks, especially in extreme climates

Adhering to a proactive maintenance plan is the single most effective way to maximize a Legacy’s lifespan across generations.

Buying used for longevity: signs a Legacy will last

If you’re shopping a used Subaru Legacy, look for a solid maintenance history and signs of careful ownership. A well-documented record often correlates with longer life. The following considerations help gauge long-term durability.

• Comprehensive service records, including timing belt/chain work, coolant/flush history, CVT fluid changes, and regular oil changes


• Evidence of preventive cooling system care (radiator, hoses, clamps, thermostat) and no chronic overheating history


• CVT condition or documented CVT service, especially on later models that used Subaru’s CVT transmissions


• Rust prevention and body/frame condition, particularly in climates with snow/road salt


• Recall completion history and any open campaigns addressed by a dealer


• Driver history compatible with longevity (no chronic aggressive driving that stresses the drivetrain)


• Historical issues known to specific model years (e.g., some EJ-era models vs. FB-era improvements) and whether those have been remedied

A meticulously maintained used Legacy with a clean service trail and no major unrepaired issues stands the best chance of delivering many more miles.

Summary

The Subaru Legacy is widely regarded as a durable, long-lasting sedan when properly cared for. A realistic expectation is 200,000 miles or more, with many owners reaching 250,000–300,000 miles and some surpassing 350,000 miles by staying on top of maintenance and driving sensibly. The key to maximizing longevity is consistent service, awareness of generation-specific needs (timing belts vs. chains, CVT maintenance), and choosing a well-documented example from a generation with robust reliability improvements. With careful ownership, the Legacy can be a capable high-mileage vehicle for many owners.

Are subarus good after 200k miles?

Yes, many Subaru models can last 200,000 miles or more with proper and consistent maintenance, which is key to their longevity. While some engine issues, like head gaskets on certain older models, can occur, regular servicing and a gentler driving style significantly increase the chances of reaching this milestone and beyond. 
Factors that contribute to longevity

• Proper Maintenance: Following the recommended service schedule is crucial, including regular oil changes, fluid replacements, and timing belt replacements when necessary. 
• Driving Style: Gentle acceleration, smooth braking, and avoiding potholes will reduce stress on the engine, brakes, and suspension. 
• Model and Engine Type: Certain models and engines are known for greater durability. For example, models with a timing chain are less prone to the timing belt issues of older models. 
• Transmission Care: For Continuously Variable Transmissions (CVTs), timely fluid changes are essential to prevent long-term damage and ensure smooth operation. 
• Highway vs. City Driving: Miles driven on the highway are generally easier on a car than the frequent stops and starts of city driving. 

Potential issues to be aware of

• Head Gaskets: On older 2.5L "EJ" engines (from about 1996 to 2012), head gasket issues can be a common problem after a certain mileage. 
• Other Repairs: Like any car, other components may need replacing over time, such as a wheel bearing or other gaskets. 
• CVT Reliability: While some newer CVTs are proving durable, some older or specific CVT models have had failures at lower mileages. 

Which Subaru will last the longest?

The longest-lasting Subaru models are generally considered to be the Outback, Forester, and Legacy, which can last between 200,000 and 300,000 miles with proper maintenance. These vehicles are known for their durable engineering, with the Subaru Boxer engine and Symmetrical All-Wheel Drive system being key to their longevity. Regular maintenance, such as oil changes and fluid checks, is crucial to maximizing their lifespan.
