The Subaru Ascent has made a name for itself as a reliable family SUV, but like any vehicle, it’s not without its issues, particularly when it comes to its engine. Owners have reported a range of symptoms that can indicate underlying problems. Recognizing these symptoms early can save you time, money, and headaches down the road.
Common Symptoms of Engine Issues
Unusual Noises
One of the first signs that something might be off with your engine is unusual noises. If you hear knocking, ticking, or grinding sounds, it’s a red flag. These noises can stem from various sources, including:
- Worn engine components
- Poor lubrication
- Issues with the timing belt or chain
Warning Lights
Dashboard warning lights are your vehicle’s way of communicating with you. If the check engine light comes on, it’s time to take notice. This light can indicate a multitude of issues, such as:
- Faulty sensors
- Engine misfires
- Exhaust system problems
Performance Issues
If your Ascent is struggling to accelerate or feels sluggish, it’s not just a minor annoyance. Performance issues can be a sign of deeper engine problems. Symptoms may include:
- Reduced power during acceleration
- Rough idling
- Stalling or hesitation when driving
Fluid Leaks
Fluid leaks under your vehicle can indicate serious engine problems. Common fluids to watch for include:
- Engine oil
- Coolant
- Transmission fluid
If you notice any puddles or spots where you park, it’s essential to investigate the source.
Excessive Exhaust Smoke
If you see smoke coming from the exhaust, it’s a clear indication that something is wrong. Different colors of smoke can indicate different issues:
- Blue smoke: Oil burning
- White smoke: Coolant leaking into the engine
- Black smoke: Too much fuel being burned
Overheating
An overheating engine is not just a nuisance; it can lead to catastrophic failure. If your temperature gauge is consistently in the red, you may be facing:
- Coolant leaks
- Thermostat issues
- Water pump failure
Conclusion
While the Subaru Ascent is generally a solid vehicle, being aware of these symptoms can help you catch engine problems before they escalate. Regular maintenance and vigilance are key to keeping your SUV running smoothly.
