Engine

2.0L Turbocharged Inline-4 (LSY)

  • Solution: GM has released updated PCV valve designs and piston ring designs to address this. Replacing the affected components may reduce oil consumption. Some cases may require engine replacement.
  • Estimated Cost to Fix: $500 - $7,000+ (depending on the extent of the repair, whether PCV, Piston rings, or Full Engine Replacement)
  • Recalls: None Found
• Turbocharger Issues
  • Description/Symptoms: Reports of premature turbocharger failure, leading to reduced engine power, unusual noises (whining or whistling), and potential engine damage.
  • Solution: Turbocharger replacement is usually necessary. Diagnose and address any underlying issues (e.g., oil starvation, boost leaks) to prevent recurrence.
  • Estimated Cost to Fix: $1,500 - $2,500+
  • Recalls: None Found

Transmission
