  • Description/Symptoms: Some owners have reported higher-than-expected oil consumption, requiring frequent top-offs between oil changes. Blue smoke may be visible from the exhaust pipe.
  • Solution: A revised PCV valve or piston ring design might be needed to address the issue. A compression test can help diagnose the severity.
  • Estimated Cost to Fix: $500 - $3,000+, depending on the severity (PCV Valve Replacement vs. Piston Ring Replacement).
  • Recalls: None Found
• Coolant Leaks
  • Description/Symptoms: Coolant leaks originating from the water pump or turbocharger coolant lines. Low coolant levels, engine overheating, and a sweet smell from the engine bay are common symptoms.
  • Solution: Replace the leaking water pump or coolant lines. Ensure proper torque specifications are followed during installation.
  • Estimated Cost to Fix: $300 - $800
  • Recalls: None Found

Transmission

• Rough Shifting/Hesitation
  • Description/Symptoms: Some owners have reported harsh or erratic shifting, particularly when shifting between lower gears. Hesitation when accelerating or a “clunking” sound during gear changes may also be present.
  • Solution: In some cases, a transmission control module (TCM) re-programming or software update can resolve the issue. A fluid flush and filter replacement may also help. More severe cases might require valve body replacement or transmission rebuild.
  • Estimated Cost to Fix: $100 (Software Update) - $4,000+ (Transmission Rebuild/Replacement)
  • Recalls: None Found

Suspension

• Rear Shock Absorber Leaks
  • Description/Symptoms: Premature failure of the rear shock absorbers, leading to fluid leaks and diminished ride quality. Bouncy ride, excessive body roll, and noise over bumps are indicators.
  • Solution: Replacement of the faulty shock absorbers. It is recommended to replace both rear shocks simultaneously.
  • Estimated Cost to Fix: $300 - $600
  • Recalls: None Found

Electrical

• Infotainment System Freezing/Rebooting
  • Description/Symptoms: The infotainment system may freeze, become unresponsive, or randomly reboot. This can affect navigation, audio, and climate control functions.
  • Solution: First, try a software update or a hard reset of the system. If the problem persists, the infotainment unit may need to be replaced.
  • Estimated Cost to Fix: $0 (Software Update) - $1,000+ (Infotainment Unit Replacement)
  • Recalls: None Found
• Battery Drain
  • Description/Symptoms: The vehicle’s battery drains prematurely, especially when the car is not driven for extended periods. This can lead to difficulty starting the engine or complete battery failure.
  • Solution: Check for parasitic draws by testing the amperage draw when the vehicle is turned off. Common causes include aftermarket accessories, a faulty body control module (BCM), or a failing alternator.
  • Estimated Cost to Fix: $100 - $500+, depending on the source of the drain.
  • Recalls: None Found

Exterior
