10 FAQs for Buyers

1. Are the 2014-2019 Legacy and Outback reliable?

Generally yes, with above-average reliability ratings. The CVT transmission and oil consumption issues are the main concerns. Models from 2016+ with updated engines tend to have fewer problems. Regular CVT fluid changes are critical.

2. Which engine should I choose: 2.5L or 3.6L?

The 2.5L 4-cylinder is adequate for most driving and offers better fuel economy. The 3.6L 6-cylinder provides more power for towing and highway passing but has lower MPG and higher maintenance costs. If you don’t need the extra power, stick with the 2.5L.

3. What is the CVT transmission like?

Subaru’s CVT is smooth and fuel-efficient but has had reliability concerns. Key to longevity: change CVT fluid every 30,000 miles (despite Subaru saying “lifetime fluid”). The transmission can be expensive to replace ($4,000-$8,000).

4. How much can these vehicles tow?

• 2.5L models: 2,700 lbs
• 3.6L models: 3,000 lbs (Outback), 3,500 lbs (Legacy with towing package)

5. What is EyeSight and is it worth it?

EyeSight is Subaru’s suite of driver assistance features including adaptive cruise control, pre-collision braking, and lane-keeping assist. It’s highly recommended and became standard on many trims by 2019. Very effective safety system.

6. Are parts and maintenance expensive?

Moderate. More expensive than Honda/Toyota but less than European brands. AWD components and horizontally-opposed engine design make some repairs more labor-intensive. Budget $500-$800/year for routine maintenance.

7. Which model year is best to buy?

2016-2017 offer the best balance of updated features, resolved early issues, and value. 2018-2019 have newer tech but command higher prices. Avoid early 2014-2015 models with oil consumption issues.

8. What should I check when buying used?

• CVT service history (fluid changes)
• Oil consumption records
• EyeSight system functionality
• Infotainment operation
• Undercarriage rust (if in salt-belt state)
• Recalls completed
• Head gasket condition

9. How does the Outback compare to the Legacy?

The Outback offers more ground clearance (8.7″ vs 5.9″), more cargo space, and a more rugged appearance. The Legacy is more car-like to drive with better fuel economy. Both share mechanicals otherwise.

10. What’s the real-world fuel economy?

• 2.5L: Expect 24-26 mpg combined (city/highway mix)
• 3.6L: Expect 20-23 mpg combined
• Highway cruising can achieve 30+ mpg with the 2.5L

Final Buyer Recommendations

✅ Buy If:

• You need standard AWD for weather/terrain conditions
• You value safety (excellent crash ratings and EyeSight)
• You want a practical, spacious vehicle with good visibility
• You plan to keep up with regular maintenance (especially CVT fluid)
• You’re buying 2016+ models with service records
• You want something more adventurous than a sedan but not a full SUV (Outback)

⚠️ Be Cautious If:

• You’re looking at high-mileage examples (100k+) without CVT service records
• The vehicle has 2014-2015 2.5L engine with unknown oil consumption history
• You want the absolute lowest cost of ownership (Honda/Toyota are cheaper)
• You need to tow regularly over 3,000 lbs
• You’re not willing to spend on 30k-mile CVT fluid changes

❌ Avoid If:

• You don’t need AWD (you’re paying for it in fuel economy and maintenance)
• You want sporty performance (these prioritize comfort and utility)
• You can’t find service records showing CVT fluid changes
• The infotainment is a dealbreaker (2014-2016 systems are dated)

Best Bang for Buck:

2016-2017 Subaru Outback 2.5i Premium with EyeSight

• Updated engine resolving oil consumption issues
• EyeSight safety features
• Good balance of features and value
• Still relatively affordable on used market ($15,000-$22,000 depending on mileage)

What to Pay (2024 Market Estimates):

• 2014-2015: $10,000-$16,000
• 2016-2017: $15,000-$22,000
• 2018-2019: $20,000-$28,000

(Prices vary by mileage, condition, trim, and location)

Our Final Verdict

The 2014-2019 Legacy and Outback are solid, practical vehicles with excellent safety and standard AWD. They’re not as bulletproof as Toyotas or Hondas, but they offer unique advantages for buyers who need all-weather capability. The key to long-term satisfaction is religious maintenance, especially CVT fluid changes every 30,000 miles. Buy from 2016+ with service records, budget for maintenance, and you’ll have a capable, safe vehicle for years to come.

Common Electrical Issues

The 2015 Subaru Forester is generally reliable, but some owners have reported electrical issues. Here are the most common ones:

1. Battery Drain Problems
   • Some owners have reported premature battery failure or parasitic drain. This is often caused by faulty alternators, aftermarket accessories, or issues with the electrical system.
   • Solution: Regularly check the battery health and ensure the alternator is functioning correctly. If the issue persists, inspect the wiring for parasitic drains.
2. Blown Fuses
   • A few owners have experienced blown fuses, particularly in the dashboard or infotainment system. This is often due to overloading the electrical system or faulty components.
   • Solution: Replace the fuse with the correct amperage and inspect the circuit for potential shorts.
3. Infotainment System Glitches
   • The Starlink infotainment system in the 2015 Forester has been known to freeze, reboot, or fail to connect to devices.
   • Solution: Software updates from Subaru dealerships can often resolve these issues. If the problem persists, the head unit may need replacement.

Common Mechanical Issues

The 2015 Forester is mechanically sound, but a few recurring problems have been reported:

1. Excessive Oil Consumption
   • Some 2.5L FB25 engines in the 2015 Forester have been known to consume excessive oil between oil changes. This issue was addressed in a Technical Service Bulletin (TSB) by Subaru.
   • Solution: Regularly monitor oil levels and top off as needed. If the problem is severe, Subaru may perform an engine repair or replacement under warranty.
2. CVT (Continuously Variable Transmission) Issues
   • Owners have reported jerking, hesitation, or shuddering during acceleration, particularly in models equipped with the CVT.
   • Solution: Subaru has released software updates to improve CVT performance. If the issue persists, the transmission may need to be inspected or replaced.
3. Suspension Noise
   • Some drivers have reported clunking or knocking noises from the suspension, often caused by worn struts or bushings.
   • Solution: Inspect and replace worn suspension components as needed.
4. Brake Problems
   • A few owners have noted premature brake wear or squeaking noises.
   • Solution: Regularly inspect and replace brake pads and rotors as needed.

Recalls:

The 2015 Subaru Forester has been subject to several recalls. Here are the most notable ones:

• Occupant Detection System (ODS) Recall:

• • Subaru recalled certain 2015-2018 Forester models equipped with heated seats due to a potential loosening of an electrical connection in the front passenger seat. This issue could deactivate the front passenger airbag, increasing the risk of injury in a crash.
    consumerreports.org

     

• Brake Light Switch Malfunction:

  • A recall was issued for multiple Subaru models, including the 2015 Forester, due to potential malfunction of the brake light switch. This could prevent the brake lights from illuminating and also prevent keyless ignition vehicles from starting or automatic transmissions from shifting out of Park.
