Engine

1.6L Turbocharged Inline-4 (LTG)

• Excessive Oil Consumption
  • Description/Symptoms: Some owners have reported higher than expected oil consumption, requiring more frequent oil top-offs between scheduled oil changes. This can lead to low oil levels and potential engine damage if not monitored.
  • Solution: The cause of excessive oil consumption is variable. Some owners have success switching to a different brand of oil or a higher viscosity. In more severe cases, piston ring failure may be suspected, which would require an engine rebuild or replacement.
  • Estimated Cost to Fix: $100 - $5,000+
  • Recalls: None Found
• Turbocharger Issues
  • Description/Symptoms: Some owners have reported turbocharger failure, leading to loss of power, unusual noises (whining, whistling), and potential check engine lights.
  • Solution: Turbocharger replacement is often necessary. Inspecting oil lines and ensuring proper lubrication is crucial for preventing recurrence.
  • Estimated Cost to Fix: $800 - $2,000+
  • Recalls: None Found

Transmission

6-Speed Automatic (6T40)

• Harsh Shifting/Slipping
  • Description/Symptoms: Some owners have experienced harsh or erratic shifting between gears, especially during acceleration or deceleration. Transmission slipping, where the engine revs without a corresponding increase in speed, has also been reported.
  • Solution: In many cases, a transmission fluid flush and filter change can alleviate minor issues. However, more severe cases may require valve body repair or replacement, or even a complete transmission rebuild or replacement.
  • Estimated Cost to Fix: $150 - $4,000+
  • Recalls: None Found

Electrical

• Infotainment System Freezing/Crashing
  • Description/Symptoms: The infotainment system (radio, navigation, etc.) can occasionally freeze, become unresponsive, or crash, requiring a system reboot.
  • Solution: Software updates can sometimes resolve these issues. In other cases, replacement of the infotainment module may be necessary.
  • Estimated Cost to Fix: $0 (software update) - $1,000+ (module replacement)
  • Recalls: None Found
• Convertible Top Malfunctions
  • Description/Symptoms: The convertible top may fail to operate correctly, getting stuck mid-cycle, or not opening/closing completely. This can be due to sensor issues, hydraulic pump failures, or problems with the mechanical linkages.
  • Solution: Diagnosis is critical to pinpoint the source of the problem. Solutions range from sensor replacement to hydraulic pump repair/replacement or mechanical linkage adjustments.
  • Estimated Cost to Fix: $100 - $2,000+
  • Recalls: None Found

Interior

• Seat Heater Failure
  • Description/Symptoms: The seat heaters may stop working on one or both front seats. This is often due to a break in the heating element within the seat.
  • Solution: Replacement of the seat heating element is the typical solution.
  • Estimated Cost to Fix: $200 - $500+ per seat
  • Recalls: None Found

Exterior

• Convertible Top Leaks
  • Description/Symptoms: Water leaks around the convertible top seals, particularly in heavy rain or car washes.
  • Solution: Inspect and replace worn or damaged weatherstripping and seals. Adjustments to the top mechanism can also help improve sealing.
