• Carbon Buildup
  • Description/Symptoms: Over time, carbon deposits can accumulate on the intake valves, especially in direct-injection engines. This can lead to rough idling, reduced power, decreased fuel economy, and potential misfires.
  • Solution: A professional intake valve cleaning service, such as walnut blasting, is typically required to remove the carbon buildup.
  • Estimated Cost to Fix: $500 - $800+
  • Recalls: None Found
• Water Pump Failure
  • Description/Symptoms: The water pump may fail, leading to coolant leaks and overheating. Symptoms include a whining noise from the engine, visible coolant leaks near the water pump, and rising engine temperature.
  • Solution: Replace the water pump, often along with the thermostat and coolant.
  • Estimated Cost to Fix: $400 - $700+
  • Recalls: None Found

Transmission

• Harsh Shifting
  • Description/Symptoms: Some owners have reported harsh or jerky shifting, especially between lower gears. This can be more noticeable during cold starts or in stop-and-go traffic.
  • Solution: In some cases, a transmission fluid flush and software update can resolve the issue. If the problem persists, more extensive repairs such as valve body replacement or a full transmission rebuild may be necessary.
  • Estimated Cost to Fix: $200 (fluid flush) to $3,000+ (transmission rebuild)
  • Recalls: None Found

Suspension

• Creaking/Squeaking Noises
  • Description/Symptoms: Some owners have reported creaking or squeaking noises coming from the suspension, particularly when going over bumps or turning at low speeds. This is commonly caused by worn or dry suspension bushings.
