Engine

4.6L Modular V8

• Spark Plug Thread Failure
  • Description/Symptoms: Spark plugs can become seized in the cylinder head, leading to stripped threads or spark plug breakage during removal. This manifests as difficulty removing the spark plugs, hissing sounds indicating a leak, and potential misfires.
  • Solution: Use penetrating oil before attempting spark plug removal. If threads are damaged, use a thread repair kit (Heli-Coil or similar) or replace the cylinder head.
  • Estimated Cost to Fix: $50 - $200+ (thread repair), $500 - $1500+ (cylinder head replacement)
  • Recalls: None Found
• Intake Manifold Cracks
  • Description/Symptoms: The intake manifold is made of plastic and can develop cracks, especially around the coolant crossover. This leads to coolant leaks, overheating, and potential engine damage.
  • Solution: Replace the intake manifold with an updated design that addresses the weak points.
  • Estimated Cost to Fix: $300 - $800
  • Recalls: None Found

Transmission

4-Speed Automatic (4R70W/4R75W)

• Shift Flare/Slipping
  • Description/Symptoms: The transmission hesitates or slips during shifts, especially between 2nd and 3rd gear. This can be caused by worn friction plates, valve body issues, or low fluid level.
  • Solution: Check and adjust the transmission fluid level. If the issue persists, consider a transmission flush (if appropriate) or valve body replacement. More severe cases may require a transmission rebuild or replacement.
  • Estimated Cost to Fix: $50 - $100 (fluid adjustment), $100 - $300 (flush), $300 - $800 (valve body), $1500 - $3500+ (rebuild/replacement)
  • Recalls: None Found
• Torque Converter Failure
  • Description/Symptoms: Shuddering or vibrations at low speeds, especially during acceleration. May also cause stalling or poor fuel economy.
  • Solution: Replace the torque converter.
  • Estimated Cost to Fix: $500 - $1200
  • Recalls: None Found

Suspension

• Air Suspension Failure
  • Description/Symptoms: The rear suspension sags or collapses. Can be caused by leaks in the air springs, compressor failure, or faulty ride height sensors.
  • Solution: Replace the air springs, compressor, or ride height sensors as needed. Consider converting to coil springs as a more permanent solution.
  • Estimated Cost to Fix: $300 - $800+ (per air spring), $400 - $1000+ (compressor), $800 - $1500 (coil spring conversion)
  • Recalls: None Found

Electrical

• Door Lock Actuator Failure
  • Description/Symptoms: The power door locks fail to operate correctly, either intermittently or completely.
  • Solution: Replace the faulty door lock actuator.
  • Estimated Cost to Fix: $150 - $400 (per door)
  • Recalls: None Found
• Blend Door Actuator Failure
  • Description/Symptoms: One side of the vehicle is hot while the other is cold, or the temperature is stuck on one setting.
  • Solution: Replace the faulty blend door actuator.
  • Estimated Cost to Fix: $200 - $500
  • Recalls: None Found

Exterior

• Rust on Lower Body Panels
  • Description/Symptoms: Rust forming on the lower edges of the doors, quarter panels, and rocker panels.
  • Solution: Remove rust, repair affected areas, and repaint.
  • Estimated Cost to Fix: $200 - $1000+ (per panel, depending on severity)
  • Recalls: None Found

Interior

• Cracked Dash Board
  • Description/Symptoms: The dash board has severe cracking due to sun exposure and age.
  • Solution: Replace the dash board or install a cover.
  • Estimated Cost to Fix: $300-$1,200+
  • Recalls: None Found
