2024 GMC Terrain

The 2024 GMC Terrain is a compact SUV that offers a comfortable ride and a stylish exterior. It comes standard with a 1.5L turbocharged four-cylinder engine producing 175 horsepower and 203 lb-ft of torque, paired with a 9-speed automatic transmission. While owners generally appreciate the Terrain’s user-friendly infotainment system and spacious interior for its class, some common criticisms include its relatively uninspiring acceleration and the lack of more powerful engine options.

This is sometimes related to PCV valve issues, or piston ring issues.
  • Solution: A compression test and leak-down test can diagnose piston ring issues. Replacement of the piston rings, or in severe cases, engine replacement may be required. Replacing the PCV valve may address issues related to oil consumption.
  • Estimated Cost to Fix: $50 - $150 for PCV valve, $2,500 - $5,000+ for piston ring replacement or engine replacement.
  • Recalls: None Found
• Turbocharger Failure
  • Description/Symptoms: Reduced engine power, whistling noises from the engine bay, and potential check engine light.
  • Solution: Diagnosis to confirm turbocharger failure. Replacement of the turbocharger is required.
