Engine

2.0L Inline-4 (G4GC)

• Engine Knocking/Piston Slap
  • Description/Symptoms: A noticeable knocking or tapping sound coming from the engine, especially when cold. This could be a symptom of piston slap or excessive wear in the cylinder bores.
  • Solution: Diagnosis by a mechanic to determine the exact cause of the noise. Depending on the severity, the repair could range from using a heavier weight oil to a complete engine rebuild or replacement.
  • Estimated Cost to Fix: $100 - $4000+
• Oil Leaks
  • Description/Symptoms: Oil leaks around the valve cover gasket, oil pan gasket, or crankshaft seal. This can lead to low oil levels, potential engine damage, and oil spots on the ground.
  • Solution: Replacement of the leaking gasket or seal.
  • Estimated Cost to Fix: $100 - $500+
• Check Engine Light - P0420 Code (Catalytic Converter Efficiency Below Threshold)
  • Description/Symptoms: The check engine light illuminates, accompanied by the P0420 code. This indicates the catalytic converter is not functioning efficiently, potentially due to age or damage.
  • Solution: Diagnosis to rule out other potential causes (O2 sensors, exhaust leaks) and replacement of the catalytic converter if confirmed.
  • Estimated Cost to Fix: $300 - $800+
  • Recalls: None Found

Transmission

4-Speed Automatic

• Harsh Shifting/Slipping
  • Description/Symptoms: The transmission shifts harshly, hesitates, or slips between gears. This can be more pronounced when the transmission is cold.
  • Solution: Start with a transmission fluid flush and filter change. If the issue persists, further diagnosis might reveal worn solenoids, valve body issues, or internal damage requiring a rebuild or replacement.
  • Estimated Cost to Fix: $100 (fluid flush) - $2500+ (rebuild/replacement)
• Delayed Engagement
  • Description/Symptoms: A delay between shifting into drive or reverse and the vehicle actually moving. This can be accompanied by a clunking noise.
  • Solution: Diagnosis to determine if the issue is with the transmission itself or related to low fluid level or a malfunctioning torque converter. Repairs could range from fluid replacement to transmission overhaul.
  • Estimated Cost to Fix: $100 - $2500+
  • Recalls: None Found

Suspension

• Worn Struts/Shocks
  • Description/Symptoms: Bouncy ride, excessive body roll in corners, and nose-diving during braking.
  • Solution: Replacement of the worn struts and/or shocks. It’s generally recommended to replace them in pairs (front or rear) for balanced handling.
  • Estimated Cost to Fix: $300 - $800+ per axle
• Clunking Noise from Suspension
  • Description/Symptoms: A clunking or rattling noise coming from the suspension, especially when going over bumps. This could indicate worn sway bar links, ball joints, or control arm bushings.
  • Solution: Inspection of the suspension components to identify the source of the noise and replacement of the worn parts.
  • Estimated Cost to Fix: $100 - $500+ per corner

Electrical

• Faulty Window Motor
  • Description/Symptoms: The power windows operate intermittently or fail to function at all. This is often caused by a failing window motor.
  • Solution: Replacement of the faulty window motor.
  • Estimated Cost to Fix: $150 - $400+ per window
• Door Lock Actuator Failure
  • Description/Symptoms: The power door locks operate intermittently or fail to function. This is often caused by a failing door lock actuator.
  • Solution: Replacement of the faulty door lock actuator.
  • Estimated Cost to Fix: $150 - $400+ per door

Exterior

• Rust near Rear Wheel Wells
  • Description/Symptoms: Rust forming on the exterior of the vehicle near the rear wheel wells and quarter panels.
  • Solution: Removal of rust and patching any holes or thin spots. If too severe, replacing the entire panel may be necessary.
  • Estimated Cost to Fix: $200 - $2,000+

Interior

• Cracked Dashboard
  • Description/Symptoms: The dashboard develops cracks, often due to sun exposure and age.
  • Solution: Replacement of the entire dashboard, or installing a dashboard cover to hide the cracks.
  • Estimated Cost to Fix: $100-$1000+
