How long will a 2015 Subaru WRX last?

In general, a well-maintained 2015 WRX can reach around 200,000 miles and often more, with many examples hitting 250,000 miles or beyond. Longevity depends on maintenance, driving habits, and climate.

What influences its lifespan?

Several factors shape how long the car will run, from maintenance discipline to road conditions and how the car is driven.

• Maintenance history and adherence to service intervals


• Engine and transmission wear due to driving style (aggressive throttle, frequent high-rpm use)


• Environmental conditions (extreme heat, cold, salted roads) and storage


• Quality of fluids and lubrication (synthetic oil, coolant, transmission fluid)


• Use of the turbocharged engine and required warmup and cooling after heavy use

With careful maintenance and mindful driving, a 2015 WRX can approach or exceed typical lifespans for modern turbocharged cars.

Engine and drivetrain reliability

Engine design and robustness

The 2015 WRX uses Subaru's 2.0-liter turbocharged flat-four, a direct-injection engine with a timing chain rather than a belt. The design is generally robust when properly maintained, but high-mileage examples require attention to oil health, coolant, and carbon buildup due to direct injection.

Transmission choices and longevity

Most 2015 WRX models came with a manual six-speed gearbox; a CVT automatic was also available. Manual transmissions tend to be durable with regular clutch and fluid changes, while CVTs can experience wear-related issues if not serviced and if the vehicle was driven aggressively. Plan for transmission fluid changes as per the owner’s manual and be attentive to unusual slipping or shuddering.

Maintenance milestones and routines

Regular maintenance is the best predictor of long life. Below are the typical milestones and tasks that help ensure longevity.

• Oil changes every 5,000–7,500 miles (or per manual) using synthetic 0W-20 oil, with proper oil filter


• Spark plugs typically replaced around 60,000–100,000 miles (varies by model)


• Coolant and radiator system inspection at every major service; coolant flush typically every 100,000 miles or per Subaru guidance


• Brake fluid and transmission fluid changes per schedule; differential fluids checked


• Air filter replacement and clean intercooler/PCV system to manage carbon buildup


• Timing chain, tensioners, water pump and related seals as part of major service around higher mileage

Adhering to these milestones helps prevent many common failures and keeps performance consistent.

Common failure points to watch for

Several issues are known to affect some 2015 WRX owners, especially with higher mileage or aggressive driving. Being aware of them can help with early intervention.

• Turbocharger oil seals and oil consumption; monitor oil level and use quality oil


• Carbon buildup on intake valves from direct injection; consider periodic decarbonization for high-mileage cars


• Intercooler leaks or boost leaks and PCV system problems


• CVT oil life or manual clutch wear in transmission variants


• Cooling system wear (radiator fans, water pump) and radiators at end of life in high-mileage cars


• Suspension and wheel bearings; general wear items that can affect reliability and ride quality

Prompt attention to these items can prevent bigger, costlier repairs and extend the car’s usable life.

Real-world ownership costs and expectations

Owners who stay current on maintenance and avoid extreme, unplanned abuse tend to see the best longevity, with many hitting 200,000 miles or more. The average annual repair costs for a WRX tend to be comparable to other performance-oriented daily drivers, but turbo-related maintenance costs can rise with mileage.

In practice, a 2015 WRX that has been well cared for—regular oil changes, timely replacements of spark plugs and fluids, and attentive turbo and cooling system maintenance—can serve as a dependable daily driver and occasional performance car well into the higher mileages appreciated by enthusiasts.

Summary

Bottom line: a 2015 Subaru WRX, when properly maintained, has the potential to last around 200,000 miles or more, with many owners reporting 250,000 miles and beyond. Regular servicing, cautious driving, and awareness of turbo and carbon buildup-related issues are the keys to unlocking the longest lifespan.

Careful maintenance and early problem detection are essential to achieving higher mileages and preserving performance. Prospective buyers should review the vehicle’s service history and consider a pre-purchase inspection if shopping for a higher-mileage example.

How many miles will a WRX last?

A Subaru WRX can last from 100,000 to over 200,000 miles, with its lifespan heavily depending on maintenance, driving habits, and a bit of luck. Consistent, regular maintenance is crucial for longevity, as is avoiding frequent, hard driving and modifications that can stress the engine. 
Factors affecting lifespan

• Maintenance: Sticking to a strict maintenance schedule, including regular oil changes, fluid checks, and replacing wear-and-tear items like the timing belt, is the most important factor for long-term reliability. 
• Driving habits: A WRX that is driven aggressively, "redlined" frequently, or launched hard, especially when not at operating temperature, will wear out faster. A more moderate driving style will contribute to a longer-lasting vehicle. 
• Modifications: While many enthusiasts modify their WRXs, certain aftermarket modifications can negatively impact the car's lifespan if not installed and tuned correctly. 
• Model year: While the general range is similar, some model years may have specific known issues. For instance, some engines (like the FA engine) may require more intensive labor for certain repairs. 
• Luck: As with any car, sometimes a component can fail unexpectedly due to unforeseen issues, regardless of maintenance. 

Common wear-and-tear items

• Clutch: The clutch, throwout bearing, and transmission are common wear items that may need replacement, especially on manual transmission models. 
• Brakes and suspension: These are considered normal maintenance items for any car and will need periodic replacement. 
• Turbo and hoses: The turbo can be a point of failure around 100,000 to 180,000 miles, while hoses may need replacement over time, especially in older vehicles. 

Is a 2015 Subaru WRX reliable?

The 2015 Subaru WRX is considered moderately reliable, but its reputation is mixed due to some specific issues like clutch problems and drivetrain concerns, particularly in manual transmission models. While some owners have reported good experiences and no issues, others have faced costly repairs. Reliability is heavily dependent on how the car was maintained and driven, with well-maintained, unmodified cars having a better chance of lasting longer. 
Factors affecting reliability

• Common problems: Some owners report issues with the clutch, throw-out bearing, and the center differential. 
• Engine and maintenance: The FA20 engine is generally considered robust, but it requires diligent maintenance. Regular oil changes (sometimes recommended every 3,000 miles) and using premium fuel are essential. 
• Modifications: Modified cars are more prone to failure due to the increased stress on the engine and drivetrain. Previous owner modifications can significantly impact a car's long-term reliability. 
• Driver habits: Aggressive driving, frequent short trips, and not allowing the turbo to cool down can shorten the life of the engine and related components. 

What to consider when buying a used 2015 WRX

• Check service history: A detailed maintenance record is crucial. Look for evidence of regular oil changes and other scheduled service. 
• Avoid modified cars: If possible, opt for a car that is stock or has modifications done professionally and has a reliable history. Be cautious of cars with a long list of performance modifications. 
• Get a pre-purchase inspection: A professional inspection, including a compression and leak-down test, can reveal potential problems before you buy. 

Will Subaru go 300,000 miles?

On average, a well-maintained Subaru Outback can last anywhere from 200,000 to 300,000 miles!
