Engine

2.0L Turbocharged Inline-4

• Excessive Oil Consumption
  • Description/Symptoms: The 2.0T engine is known for consuming excessive amounts of oil, sometimes requiring owners to add a quart of oil every 1,000 miles or less. This can manifest as a low oil light illuminating on the dashboard, or visually checking the oil level on the dipstick and discovering it is low.
  • Solution: The updated pistons and rings (parts starting with “06H”) are a common fix. PCV replacement can also assist in the fix. Some owners may choose to monitor oil levels more frequently and top off as needed, although this is not a permanent fix.
  • Estimated Cost to Fix: $3,000 - $5,000+
  • Recalls: None Found
• Timing Chain Tensioner Failure
  • Description/Symptoms: Failure of the timing chain tensioner can lead to catastrophic engine damage. Symptoms include a rattling noise on startup, especially after the car has been sitting for a while. Left unaddressed, it can cause the timing chain to skip teeth, leading to valve damage and engine failure. The earlier tensioners had issues with wear.
  • Solution: Replacing the timing chain tensioner with the updated revision. Also replace the timing chain and guides.
  • Estimated Cost to Fix: $2,000 - $4,000+
  • Recalls: None Found

3.2L V6

• Carbon Buildup on Intake Valves
  • Description/Symptoms: Direct injection engines are prone to carbon buildup on the intake valves because there is no fuel washing the valves. This can cause rough idling, misfires, decreased fuel economy, and a loss of power.
  • Solution: Manual cleaning of the intake valves using a walnut blasting or chemical treatment is a common solution. Installing an oil catch can can mitigate future buildup.
  • Estimated Cost to Fix: $500 - $1,000+
  • Recalls: None Found

Transmission

6-Speed Automatic (Tiptronic)

• Valve Body Issues
  • Description/Symptoms: Hesitation when shifting, rough shifts, or complete loss of gear engagement can indicate valve body problems within the automatic transmission. This can be due to worn solenoids or other internal components.
  • Solution: Replacing the valve body with a new or remanufactured unit. In some cases, a complete transmission rebuild or replacement might be necessary.
  • Estimated Cost to Fix: $1,500 - $4,000+
  • Recalls: None Found

6-Speed Manual

No Issues Found

Suspension

• Control Arm Bushing Failure
  • Description/Symptoms: Premature wear and failure of the control arm bushings can lead to clunking noises from the suspension, especially when going over bumps. It can also cause vague steering and uneven tire wear.
  • Solution: Replacing the worn control arm bushings or the entire control arm assembly.
  • Estimated Cost to Fix: $300 - $800+ per control arm
  • Recalls: None Found

Electrical

• Faulty Ignition Coils
  • Description/Symptoms: Misfires, rough idling, and reduced engine power can be caused by faulty ignition coils. A check engine light will likely illuminate, with codes indicating misfires.
  • Solution: Replacing the faulty ignition coil(s). It is often recommended to replace all ignition coils at the same time for preventative maintenance.
  • Estimated Cost to Fix: $100 - $300+ per coil
  • Recalls: None Found
• Power Window Regulator Failure
  • Description/Symptoms: The power windows may stop working or operate erratically. This is often caused by a faulty window regulator.
  • Solution: Replacing the faulty power window regulator.
  • Estimated Cost to Fix: $200 - $500+ per window
  • Recalls: None Found

Exterior

• Headlight Condensation
  • Description/Symptoms: Moisture can accumulate inside the headlight housing, leading to condensation. This can reduce visibility and potentially damage the headlight components.
  • Solution: Removing the headlight assembly, drying it out, and resealing it. Replacing the headlight assembly may be necessary if the damage is severe.
  • Estimated Cost to Fix: $100 - $500+ per headlight

Interior

• Sunroof Issues
  • Description/Symptoms: Sunroof may fail to open or close properly, or may make excessive noise. This can be caused by a broken track or motor failure.
  • Solution: Repair or replace the sunroof track or motor.
  • Estimated Cost to Fix: $300 - $1000+

Summary
