The 2017 Subaru models have gained attention for their performance and all-wheel-drive capabilities, but some owners have reported a range of engine-related issues that can be frustrating and costly. Understanding these problems is crucial for any Subaru owner or potential buyer. This overview will break down the common symptoms associated with engine troubles in these vehicles, helping you identify what to look for if you suspect something might be wrong.
Common Engine Symptoms
Unusual Noises
One of the first signs of engine trouble is often unusual noises. Owners have reported hearing:
- Knocking or Pinging: This could indicate issues with the engine’s internal components or fuel quality.
- Rattling Sounds: A sign of loose parts or potential failure in the timing chain or belt.
- Hissing or Whistling: This might point to a vacuum leak or issues with the intake system.
Performance Issues
If your Subaru is not performing as it should, it could be a red flag. Symptoms include:
- Loss of Power: If you notice a significant drop in acceleration or power, this could indicate engine problems.
- Stalling: An engine that stalls unexpectedly can be dangerous, especially while driving.
- Rough Idling: If the engine shakes or vibrates while idling, it may be a sign of misfiring or other internal issues.
Warning Lights
Dashboard warning lights are designed to alert drivers to potential issues. Pay attention to:
- Check Engine Light: This is the most common warning. It can signal a range of issues, from minor to severe.
- Oil Pressure Light: If this light comes on, it could indicate low oil pressure, which can lead to serious engine damage.
- Temperature Warning Light: This signals overheating, which can cause catastrophic engine failure if not addressed immediately.
Fluid Leaks
Fluid leaks can indicate serious problems. Keep an eye out for:
- Oil Leaks: Dark spots under the engine can mean oil is escaping, which can lead to severe engine damage.
- Coolant Leaks: If you see green or orange fluid, it could indicate a coolant leak, leading to overheating.
- Transmission Fluid Leaks: Red fluid under the car may indicate transmission issues, which can affect engine performance.
Fuel Economy Decline
A sudden drop in fuel efficiency can be a symptom of engine trouble. If you notice:
- Decreased Miles Per Gallon: This could indicate that the engine is not running efficiently, possibly due to a faulty sensor or other issues.
- Frequent Refueling: If you find yourself at the pump more often than usual, it’s time to investigate further.
Exhaust Issues
Your exhaust system can reveal a lot about your engine’s health. Watch for:
- Excessive Smoke: Blue smoke indicates oil burning, while black smoke suggests too much fuel is being burned.
- Strong Odors: A strong smell of gasoline or burnt oil can indicate serious engine issues.
Recognizing these symptoms early can save you from more significant problems down the road. If you experience any of these issues, it’s wise to consult a professional mechanic who can diagnose and address the root cause effectively. Understanding the symptoms of engine problems in your Subaru can help you maintain your vehicle and ensure it runs smoothly for years to come.
