This is often attributed to the aluminum cylinder head thread design and can occur on other Ford vehicles with similar engine designs.
  • Solution: Repairing the threads using a thread repair kit (like a Time-Sert) or replacing the cylinder head.
  • Estimated Cost to Fix: $500 - $2000+ depending on the extent of damage and repair method.
  • Recalls: None Found
• Intake Manifold Failure
  • Description/Symptoms: Coolant leaks developing from the intake manifold.
  • Solution: Replace the intake manifold with an updated design.
  • Estimated Cost to Fix: $500 - $800
  • Recalls: None Found

Transmission

5-Speed Automatic Transmission

• Erratic Shifting/Slipping
  • Description/Symptoms: Harsh or delayed shifts, transmission slipping between gears, or failure to shift properly.
  • Solution: Could be caused by low transmission fluid, faulty shift solenoids, valve body issues, or internal damage to the transmission. Diagnosis is key. Fluid flush, solenoid replacement, valve body repair, or full transmission replacement are possible solutions.
  • Estimated Cost to Fix: $100 (fluid change) - $3500+ (transmission replacement).
  • Recalls: None Found

Suspension

• Air Suspension Failure (If Equipped)
  • Description/Symptoms: The Aviator could be equipped with an air suspension system, which is prone to failure as the vehicle ages. Symptoms include the vehicle sitting low, uneven ride height, compressor failing to operate, and warning lights on the dashboard.
  • Solution: Replacing the air springs (airbags), air suspension compressor, or ride height sensors. Converting to a traditional coil spring suspension is another option.

Summary

The 2005 Lincoln Aviator, while offering a comfortable and stylish driving experience, is prone to several common issues. Engine issues like spark plug blowout and intake manifold failures can be costly to repair. The transmission may experience erratic shifting requiring a fluid flush or more costly overhaul/replacement. The air suspension system (if equipped) can also be a source of problems due to its age. Electrical issues and rust are also common concerns. The severity and cost of repairs vary widely, but potential buyers should be aware of these potential issues and factor them into their purchasing decision. Addressing these issues proactively with regular maintenance can help extend the life of the vehicle.
