Common Issues Reported By Owners

Subaru’s 2017 Legacy and Outback models have proven reliable, but some common issues persist, primarily related to the CVT transmission and oil consumption.

1. CVT Transmission Problems

- Problem: Hesitation, jerking, and occasional failure in the CVT.
- Symptoms: Loss of power, delayed response, high RPMs during acceleration.
- Fix: Software update, CVT fluid flush, or full transmission replacement.
- Cost: $300 for software update; $2,500–$4,000 for transmission replacement.

2. Excessive Oil Consumption (FB25 Engine)

- Problem: Higher-than-normal oil consumption, particularly in 2.5L engines.
- Symptoms: Low oil levels, engine knocking, premature engine wear.
- Fix: Frequent oil level checks or piston ring replacement.
- Cost: $1,200–$1,800 if piston rings need replacement.

3. Brake Wear and Warped Rotors

- Problem: Premature wear of brake pads and rotors, especially in Outback models.
- Symptoms: Vibration during braking, squealing noises.
- Fix: Replace pads and rotors.
- Cost: $400–$800 for a complete brake job.

4. Windshield Cracking Issue (Outback)

- Problem: Weak windshield prone to cracking from small impacts.
- Fix: Windshield replacement.
- Cost: $500–$1,000 depending on ADAS calibration.

5. Battery Drain & Electrical Issues

- Problem: Rapid battery discharge caused by parasitic drain from infotainment or Starlink system.
- Fix: Software update or replacing the battery with a higher-quality unit.
- Cost: $200–$300.

Common Mechanical Issues

Engine Concerns
- Oil Consumption: Some 2.5L FB25 engines may burn oil excessively due to piston ring design flaws, particularly in high-mileage examples.
- CVT (Continuously Variable Transmission):
  - Shuddering/Jerking: Reports of rough acceleration or hesitation, especially in cold weather.
  - Failure Risk: Rare but costly transmission replacements (Subaru extended CVT warranties to 10 years/100,000 miles for 2017 models).
Suspension and Steering
- Strut/Shock Mount Wear: Clunking noises over bumps, particularly in Outback models used for off-road or heavy hauling.
- Wheel Bearings: Premature failure causing humming or grinding noises.
Brake System
- Premature Brake Pad/Rotor Wear: Aggressive braking or city driving accelerates wear.
- Brake Lamp Switch Failure: Faulty switches trigger warning lights (recall issued).
Cooling System
- Thermostat Housing Leaks: Plastic components may crack, leading to coolant leaks.

Common Electrical Issues

Infotainment System
- Starlink Glitches: Freezing screens, unresponsive touch controls, or Bluetooth/Apple CarPlay disconnections.
- Navigation Errors: Outdated maps or software bugs.
Eyesight Safety System
- Camera/Sensor Malfunctions: Dirty or obstructed cameras disable adaptive cruise control or lane-keep assist.
Battery Drain
- Parasitic Draw: Faulty modules (e.g., infotainment, security) drain the battery if the vehicle sits unused.
Power Liftgate (Outback):
- Motor/Sensor Failures: Erratic operation or failure to open/close.

1. Infotainment System Problems

Issue: The Starlink infotainment system may experience glitches or freezing, with some owners reporting issues such as the screen going blank or the system rebooting randomly.
Symptoms: Unresponsive touchscreen, incorrect audio playback, or loss of Bluetooth connection.
Solution: A software update from Subaru can often fix these issues. In some cases, the head unit may need replacement.

2. Windshield Cracking

Issue: Some owners of the 2018 Outback and Legacy have reported issues with easily cracked or chipped windshields, often attributed to thin glass or manufacturing defects.
Symptoms: Visible cracks or chips that appear with minimal impact.
Solution: Replace the windshield with an OEM or aftermarket option, and consider applying a protective film to prevent future damage.

3. Battery Drain

Issue: Owners have reported premature battery failure or excessive drain, leading to difficulties starting the vehicle.
Symptoms: Slow engine crank, warning lights on the dashboard, or a dead battery after short periods of inactivity.
Solution: Replace the battery with a high-quality aftermarket or OEM battery. Ensure all electronic systems are turned off when the car is not in use.

4. Transmission Shudder

Issue: The continuously variable transmission (CVT) may develop a shudder or hesitation, particularly at low speeds or during acceleration.
Symptoms: Jerking sensation, hesitation, or whining noises during acceleration.
Solution: Check the CVT fluid and ensure it’s at the correct level. If the issue persists, Subaru may need to inspect or repair the transmission under warranty.

5. Oil Consumption

Issue: Some 2.5L engines have been reported to consume more oil than expected between oil changes.
Symptoms: Low oil levels or warning lights before the scheduled oil change interval.
Solution: Monitor oil levels frequently and top off as needed. If consumption is excessive, Subaru may perform an engine inspection or repair under warranty.

6. Suspension Noises

Issue: Owners have reported clunking or creaking noises from the suspension, especially when driving over rough roads or speed bumps.
Symptoms: Unusual noises from the front or rear suspension.
Solution: Inspect suspension components like sway bar links, bushings, and struts for wear or damage. Replace any faulty parts.

7. Wind Noise

Issue: Excessive wind noise has been reported, particularly at higher speeds, due to poor door or window seals.
Symptoms: Noticeable whistling or wind noise in the cabin while driving at highway speeds.
Solution: Inspect and replace faulty door and window seals.

8. Rearview Camera Malfunction

Issue: The rearview camera may display a black or distorted screen, or fail to activate when the car is in reverse.
Symptoms: Loss of rearview camera functionality or poor image quality.
Solution: Check for loose connections to the camera system and ensure the software is up-to-date. If the issue persists, the camera or related components may need replacement.
