  • Estimated Cost to Fix: $300 - $500
  • Recalls: None Found
• VANOS Solenoid Failure
  • Description/Symptoms: Rough idle, loss of power, check engine light. The VANOS (Variable Valve Timing) system relies on solenoids to control oil flow to the camshafts. Failure can disrupt valve timing.
  • Solution: Replace the faulty VANOS solenoid(s).
  • Estimated Cost to Fix: $200 - $400 per solenoid
  • Recalls: None Found
