Will a Subaru last 300000 miles?

Yes. Subarus can reach 300,000 miles with proper maintenance and care; the odds depend on model, climate, and how diligently you follow maintenance schedules.

What influences long-term durability?

Subaru’s design—symmetrical all-wheel drive, boxer engines, and straightforward drivetrains—offers a solid foundation for high mileage. Real-world longevity hinges on maintenance history, regular inspections, and timely repairs. The key is proactive care, not optimism alone.

Engine architecture and typical failure points

Boxer engines balance vibrations and can endure high mileage when well maintained. Earlier EJ-series 2.5L engines carried a reputation for head gasket failures, especially around the 100,000–150,000 mile mark if the cooling system wasn’t properly cared for. Later FA/FB engines moved to timing chains and improved internals, which reduces several common failure modes. Transmission choices (automatic, CVT, or manual) add their own maintenance requirements and life expectancy considerations.

Maintenance habits to maximize mileage

To maximize the odds of hitting 300,000 miles, keep to a disciplined maintenance schedule with attention to critical wear items.

• Oil changes with high-quality synthetic oil at the interval recommended by the owner’s manual (often every 5,000–7,500 miles, or six months, whichever comes first).


• Coolant system service, including periodic coolant replacement and inspection of hoses, radiator, thermostat, and water pump.


• Timing belt or chain maintenance according to engine type; EJ-series engines use a timing belt with replacement around 100,000 miles; FA/FB engines use a timing chain but still require tensioner checks and occasional service.


• Transmission/drivetrain maintenance, including fluid changes for automatics or CVTs and servicing differentials if applicable.


• Brake system upkeep, including fluid flush every 2–3 years and pad/rotor replacement as needed.


• Suspension, wheel bearings, and tires: regular inspections, alignment checks, and tire rotations to reduce wear and improve road life.


• Prioritization of rust prevention and body/chassis maintenance, especially in regions with heavy road salt or coastal corrosion.

Sticking to these practices reduces the risk of early, dramatic failures and can extend the life well beyond 200,000 miles.

Engine and model considerations by era

Older EJ-series 2.5L engines and head gasket risk

Some 1990s–2000s Subarus with the EJ25 engine are known for head gasket symptoms and leaks as mileage climbs. A history of timely head gasket service, proper cooling system maintenance, and a well-kept cooling system can still yield 200,000+ miles. If a used high-mile Subaru has had a gasket replacement and other essential maintenance, it can be a solid long-haul performer.

Newer FA/FB engines and CVT reliability

From the early 2010s onward, Subaru adopted FA/FB engines with timing chains and newer CVTs in many models. These designs can reach 200,000–300,000 miles with routine maintenance, but CVT reliability depends heavily on regular transmission fluid changes and avoiding severe lugging and overheating. Look for documented CVT service history when evaluating a high-mile example.

What to check when buying a high-mile Subaru

If you’re evaluating a Subaru with hundreds of thousands of miles, use these checks to gauge remaining life and risk:

• Inspect for head gasket symptoms: milky oil, coolant in the overflow, coolant loss without visible leaks, overheating history.


• Check oil consumption, leaks, and the condition of valve covers and cam seals; listen for rough idling or misfires that could indicate deeper issues.


• Assess the CVT or transmission: listen for slipping, shuddering, or hesitation; confirm maintenance history and fluid changes.


• Inspect cooling and heating systems: ensure radiator, thermostat, water pump, hoses, and heater core are in good condition.


• Examine the chassis for rust or frame rot and review underbody components for wear in regions with heavy road salt or snow.


• Review maintenance records: timing belt/chain service, oil changes, cooling system service, transmission/differential service, and tire rotations.

A thorough inspection and complete maintenance history can help you forecast whether a high-mileage Subaru will reach or exceed 300,000 miles.

Summary

With careful upkeep, a Subaru can reliably reach 300,000 miles and beyond. The odds improve with model choices that use durable engines and timing chains, consistent oil and coolant management, and timely transmission service. While not guaranteed, long-term Subaru ownership is a realistic goal for many drivers who stay proactive about maintenance and address issues as they arise.

How many miles do subarus typically last?

Subarus typically last between 200,000 and 300,000 miles, but this depends on proper maintenance, which includes regular oil changes and fluid checks. Some models, like the Crosstrek, can even exceed 250,000 miles, while high-performance models like the WRX may be closer to 150,000+ miles if they aren't maintained according to their specific schedules. 
Expected mileage by model

• Outback, Forester, and Legacy: Can often exceed 200,000 miles, with many reaching 250,000 to 300,000 miles with proper care. 
• Crosstrek: Known to last more than 250,000 miles. 
• Ascent: Can typically last between 200,000 and 250,000 miles. 
• WRX and WRX STI: With strict maintenance, these performance models can last over 150,000 miles. 

Factors that influence longevity

• Regular maintenance: Following the manufacturer's recommended service schedule is crucial. This includes routine oil changes, tire rotations, and fluid flushes. 
• Driving habits: Responsible driving habits can help maximize a vehicle's lifespan. 
• Proper care: Addressing minor issues before they become major problems can prevent larger, more costly repairs down the road. 

Can a Subaru last 300k miles?

With regular maintenance and responsible driving, models like the Subaru Outback and Forester can last between 200,000 and 300,000 miles. This impressive lifespan is due to Subaru's commitment to quality engineering, including the use of high-caliber materials and advanced safety features.

Can a transmission last 300k miles?

Yes, a transmission can last 300,000 miles or more, but this depends heavily on proper maintenance, driving habits, and the specific vehicle. Regular maintenance, like fluid changes, is crucial, while factors such as driving conditions and how the vehicle is used (e.g., towing heavy loads) will also impact its lifespan.

Is it worth buying a Subaru with over 200k miles?

You should only consider buying a Subaru with 200k miles if it has a complete maintenance history, has had major components replaced, and passes a thorough pre-purchase inspection. While Subarus can last beyond 200k miles, a vehicle at this mileage will have significant wear and tear and is likely to need costly repairs soon.
 
What to look for

• Maintenance records: A well-maintained Subaru is crucial for longevity. Look for consistent service, especially for the timing belt (if applicable), head gaskets, and other engine components. 
• History: An inspection of the vehicle history report is important to understand the car's past. Look for signs of accidents or a history of consistent use. A vehicle with one or two owners is often a better bet. 
• Pre-purchase inspection: Have a trusted mechanic thoroughly inspect the car, focusing on the engine, transmission, suspension, and any other potential failure points at this mileage. 
• Past repairs: Ideally, major repairs like the head gasket, water pump, and transmission should have already been completed. 

Potential issues at 200k miles

• Engine and transmission: These are the most expensive components to replace. Be prepared for potential failures or significant maintenance costs. 
• Suspension and brakes: Components like the suspension, brakes, and exhaust can rust out or wear out, requiring replacement. 
• Other components: Expect a higher likelihood of smaller issues like worn-out seals, bushings, and other small parts that can lead to costly repairs if not addressed. 

When to avoid

• No service history: Without records, it's a high-risk purchase. You won't know how well the car was maintained. 
• Major issues found in inspection: If a pre-purchase inspection reveals any major problems with the engine, transmission, or other core systems, walk away. 
• High number of owners: A car with many owners is more likely to have been poorly maintained or neglected.
