- Warning lights on the dashboard, such as the check engine light
- Unusual noises from the engine bay
- Increased fuel consumption or hybrid system inefficiency

Diagnosis:
- Use an OBD-II scanner to check for fault codes related to ignition, fuel injection, or hybrid system components.
- Inspect spark plugs and ignition coils for wear or damage.
- Check the hybrid battery state and electric motor functionality.
- Examine air intake and turbocharger systems for leaks or blockages.
- Verify software updates are installed, as DFKA engines benefit from ECU calibrations.

Fixes:
- Replace worn or faulty spark plugs and ignition coils to restore smooth combustion.
- Repair or replace damaged air intake components or turbocharger parts to ensure proper airflow.
- Perform hybrid system diagnostics and replace failing battery modules or electric motor parts as needed.
- Update engine control software to the latest version to improve performance and reliability.
- Clean or replace fuel injectors to maintain efficient fuel delivery.

Prevention:
- Follow the manufacturer’s recommended maintenance schedule, including regular oil changes with the specified grade.
- Use high-quality fuel and hybrid system fluids to prevent deposits and corrosion.
- Periodically inspect ignition and air intake components to catch early signs of wear.
- Keep the hybrid battery charged and avoid deep discharges to extend its lifespan.
- Ensure timely software updates during routine service visits to optimize engine management.
