The 2019 Subaru Ascent has made a name for itself as a family-friendly SUV with ample space and a solid reputation. However, like any vehicle, it’s not without its issues, particularly when it comes to its engine. Owners have reported a variety of symptoms that can be concerning and may indicate underlying problems. Understanding these symptoms is crucial for any Ascent owner or potential buyer.
Common Symptoms of Engine Issues
When it comes to engine problems, the symptoms can vary widely. Here are some of the most frequently reported issues by Ascent owners:
Strange Noises
One of the first signs that something might be wrong with the engine is unusual noises. These can include:
- Knocking or Pinging: This can indicate issues with engine timing or fuel quality.
- Grinding Sounds: Often associated with mechanical failures in engine components.
- Hissing or Whistling: Could suggest a vacuum leak or issues with the intake system.
Performance Problems
Another area where owners have reported issues is in engine performance. Symptoms in this category include:
- Loss of Power: A noticeable decrease in acceleration or overall engine responsiveness.
- Rough Idling: The engine may shake or vibrate excessively when at a standstill.
- Stalling: The engine may unexpectedly shut off, particularly when idling or during low-speed maneuvers.
Warning Lights
Modern vehicles are equipped with various sensors and warning lights that can alert drivers to potential issues. In the Ascent, you might see:
- Check Engine Light: This can indicate a range of problems, from minor to severe.
- Oil Pressure Warning: A critical alert that should not be ignored, as it can lead to severe engine damage.
Fluid Leaks
Fluid leaks can also be a telltale sign of engine trouble. Common fluids to watch for include:
- Oil: Dark brown or black spots under the vehicle can indicate an oil leak.
- Coolant: A green or orange fluid may suggest a coolant leak, which can lead to overheating.
Fuel Efficiency Drops
A sudden drop in fuel efficiency can be another symptom of engine trouble. If you notice that you’re filling up more often without any changes in driving habits, it could be a sign of:
- Fuel System Issues: Problems with the fuel injectors or fuel pump can lead to inefficient fuel usage.
- Air Intake Problems: A clogged air filter or issues with the air intake can also affect fuel efficiency.
Conclusion
Recognizing these symptoms early can help in addressing potential engine problems before they escalate into more significant issues. If you’re experiencing any of these symptoms, it’s essential to consult a qualified mechanic for a thorough diagnosis.

Owner Experiences
Many Subaru Ascent owners have taken to forums to share their experiences regarding engine problems. Here are some common sentiments expressed:
