  • Solution: A compression test and leak-down test can help determine the source of the oil consumption. Repair options range from replacing valve stem seals to a complete engine rebuild, depending on the severity.
  • Estimated Cost to Fix: $500 - $5000+
  • Recalls: None Found
• Knock Sensor Failure
  • Description/Symptoms: The knock sensors can fail due to corrosion or age, leading to a check engine light and reduced engine performance.
  • Solution: Replace the faulty knock sensor(s).
  • Estimated Cost to Fix: $200 - $500

Transmission

4L60-E Four-Speed Automatic

• Transmission Slipping/Harsh Shifting
  • Description/Symptoms: The 4L60-E transmission is known for potential issues with slipping between gears or harsh shifting, especially as the vehicle ages. This can be caused by worn clutches or a failing valve body.
