  • Recalls: None Found

Suspension

• Strut/Shock Absorber Wear
  • Description/Symptoms: Worn struts and shocks can result in a bouncy ride, poor handling, and increased braking distance.
  • Solution: Replace worn struts and shocks.
  • Estimated Cost to Fix: $300 - $600 (for all four)
  • Recalls: None Found
• Sway Bar Link Failure
  • Description/Symptoms: Broken or worn sway bar links can cause clunking noises from the suspension, especially when going over bumps or turning.
  • Solution: Replace the sway bar links.
  • Estimated Cost to Fix: $100 - $200

Electrical

• Oxygen Sensor Failure
  • Description/Symptoms: Failed oxygen sensors can trigger a check engine light, reduce fuel economy, and affect engine performance.
  • Solution: Replace the faulty oxygen sensor(s).

Summary

The 2000 Toyota Avalon is a generally reliable vehicle but is prone to some common issues related to its age and mileage. Engine oil leaks and sludge buildup are potential concerns for the 3.0L V6. The 4-speed automatic transmission may experience shifting problems. Suspension and electrical issues are also common. Rust can be a problem, especially in areas with road salt. While many repairs are relatively inexpensive, more significant issues like engine sludge or transmission problems can be costly to address. Overall, potential buyers should have a pre-purchase inspection performed to assess the condition of these components.
