Engine

2.5L Naturally Aspirated I4

  • Recalls: None Found
• Rough Idling or Stalling
  • Description/Symptoms: Some owners have reported issues with rough idling or stalling, particularly when the engine is cold.
  • Solution: Potential causes include issues with the mass airflow sensor, throttle body, or fuel injectors. Cleaning or replacing these components may resolve the issue. A software update to the engine control module (ECM) might also be necessary.
