The 2016 Subaru models have garnered attention for a range of engine issues that can leave owners frustrated and searching for answers. While Subaru is generally known for its reliability, certain problems have emerged that are worth discussing. These issues can manifest in various ways, affecting performance and overall driving experience. If you’re driving a 2016 Subaru, it’s essential to be aware of these symptoms so you can address them promptly and avoid further complications down the road.
Common Symptoms of Engine Issues
Unusual Noises
One of the most noticeable signs of engine trouble is unusual noises coming from under the hood. These sounds can vary but often include:
- Knocking or tapping noises, which may indicate issues with the engine’s internal components.
- Rattling sounds that could suggest loose parts or failing components.
- High-pitched whining, possibly pointing to problems with the timing belt or other accessories.
Performance Problems
Another significant symptom is a decline in performance. Owners have reported various issues, including:
- Loss of power during acceleration, making it difficult to merge onto highways or overtake other vehicles.
- Rough idling, where the engine feels unstable when the vehicle is stationary.
- Poor fuel economy, which can be a sign of inefficient engine operation.
Warning Lights
Dashboard warning lights are designed to alert drivers to potential issues. If you notice any of the following lights illuminated, it’s a clear indication that something is wrong:
- The check engine light, which can signify a range of problems from minor to severe.
- The oil pressure warning light, indicating low oil pressure that could lead to engine damage.
- The temperature warning light, suggesting the engine is overheating.
Fluid Leaks
Fluid leaks can also be a telltale sign of engine problems. Keep an eye out for:
- Oil leaks, which may appear as dark spots under the vehicle.
- Coolant leaks, often visible as bright green or orange puddles.
- Transmission fluid leaks, which can be red or brown and may indicate transmission issues.
Overheating
Overheating is a critical issue that should never be ignored. If your engine temperature gauge rises into the red zone, it could mean:
- A malfunctioning thermostat that’s preventing coolant flow.
- Low coolant levels due to leaks or evaporation.
- Water pump failure, which is crucial for circulating coolant.
Excessive Exhaust Smoke
Pay attention to the color of the exhaust smoke. Different colors can indicate various problems:
- Blue smoke may suggest oil burning, often due to worn piston rings or valve seals.
- White smoke can indicate coolant entering the combustion chamber, possibly due to a blown head gasket.
- Black smoke usually means too much fuel is being burned, often due to a faulty fuel injector or air filter.
Conclusion
Recognizing these symptoms early can save you from more significant issues down the line. If you experience any of these signs, it’s wise to consult with a qualified mechanic who can diagnose and address the problem effectively.
Understanding the Issues with Subaru Engines

| Overheating | Faulty thermostat, coolant leaks | Temperature gauge in the red, steam from engine |
| Rough Idling | Fuel injector issues | Engine vibrations, stalling |
| Check Engine Light | Various sensor failures | Dashboard warning light, performance issues |
| Oil Leaks | Worn gaskets or seals | Puddles under the car, low oil pressure |
Owner Opinions from Forums
- “I’ve noticed my car burning oil at an alarming rate. I’m constantly checking and topping it off. It’s frustrating.”
- “My engine has been overheating regularly. I’ve replaced the thermostat, but the problem persists. I feel like I’m chasing a ghost.”
- “The check engine light comes on and off. I took it to the dealer, and they said it’s a sensor issue, but it keeps happening.”
- “I never expected to deal with so many leaks. I’ve had to replace gaskets multiple times, and it’s getting expensive.”
- “Rough idling has become a norm for me. It’s embarrassing when I’m at a stoplight and my car shakes.”
Impact of Engine Problems
The engine problems reported by owners can lead to several negative consequences, including:
- Increased maintenance costs due to frequent repairs.
- Decreased resale value, as potential buyers may be wary of known issues.
- Safety concerns if the engine fails while driving, leading to potential accidents.
Being aware of these issues and their causes can help owners make informed decisions about maintenance and repairs. If you own a 2016 Subaru and experience any of the symptoms mentioned, it’s crucial to consult with a qualified mechanic who understands these specific engine problems.
Recalls and Technical Service Bulletins for Engine Issues
