Engine

2.0L Turbocharged Inline-4 (EA888)

• Oil Consumption Issues
  • Description/Symptoms: Some owners have reported higher-than-expected oil consumption, requiring more frequent top-offs between oil changes. Symptoms include the need to add oil every few thousand miles, blue smoke from the exhaust upon startup, and potential low oil pressure warnings. This can be caused by piston ring issues.
  • Solution: A compression test and leak-down test can help diagnose the problem. Depending on the severity, the fix can range from using a thicker oil to a complete engine rebuild.
  • Estimated Cost to Fix: $500 - $5,000+
  • Recalls: None Found
• PCV Valve Failure
  • Description/Symptoms: The Positive Crankcase Ventilation (PCV) valve can fail, causing a vacuum leak. This leads to rough idling, poor fuel economy, and potentially a check engine light.
  • Solution: Replace the PCV valve.
  • Estimated Cost to Fix: $150 - $300+
  • Recalls: None Found
• Ignition Coil Failure
  • Description/Symptoms: One or more ignition coils can fail, leading to misfires and a rough-running engine. The check engine light will illuminate, and a diagnostic scan will reveal the faulty coil(s).

  • Estimated Cost to Fix: $2,000 - $6,000+
  • Recalls: None Found
• Clutch Wear
  • Description/Symptoms: Due to the nature of a dual-clutch transmission, clutch wear is normal but can become problematic at higher mileages. Symptoms include slipping during acceleration, shuddering, and difficulty shifting.
