Engine

2.0L Turbocharged Engine

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher-than-normal oil consumption, requiring frequent top-offs between oil changes. Symptoms include low oil level warning lights and the need to add oil regularly.
  • Solution: Some dealerships may perform an oil consumption test and potentially replace piston rings or the short block if consumption exceeds acceptable limits.
  • Estimated Cost to Fix: Varies greatly; from several hundred dollars for minor repairs to $5,000+ for short block replacement.
  • Recalls: None Found
• Rough Idling/Hesitation
  • Description/Symptoms: Some owners have reported the engine idling roughly or hesitating during acceleration, especially when cold.
  • Solution: Could be due to faulty MAF sensor, spark plugs, or vacuum leak. A diagnostic scan can pinpoint the cause. Replacing spark plugs or cleaning the MAF sensor may resolve the issue.
  • Estimated Cost to Fix: $50 - $300+ depending on the repair
  • Recalls: None Found

Transmission

6-Speed Manual Transmission

• Grinding or Difficulty Shifting into Gears
  • Description/Symptoms: Some owners have experienced grinding noises or difficulty shifting into certain gears, particularly 1st and 2nd.
