  • Cost: $400 - $2500

Transmission Fluid Leaks

  • Symptoms: Reddish fluid under the vehicle, burning smell, low transmission fluid level.
  • Solution: Replacement of seals, transmission lines, or transmission pan gasket.
  • Cost: $200 - $500

4-Speed Automatic (F4A51)

Overheating

  • Symptoms: Transmission fluid smells burnt, delayed or rough shifting, especially under load.
  • Solution: Flushing and replacing transmission fluid, checking transmission cooler for blockages or leaks.
  • Cost: $200 - $500

  • Solution: Replacement of worn ball joints and control arm bushings.
  • Cost: $400 - $900

Rear Spring Sag

  • Symptoms: Vehicle appears to sit lower in the rear, reduced ride height, potential for bottoming out.
  • Solution: Replacement of rear coil springs.
  • Cost: $300 - $600

Electrical

Body Control Module (BCM)

Intermittent Electrical Failures

  • Symptoms: Power windows not working, interior lights flickering, door locks malfunctioning, dashboard warning lights illuminating randomly.
  • Solution: Diagnosis and potential reprogramming or replacement of the BCM.
  • Cost: $500 - $1000

Alternator

Premature Failure

Summary Verdict

The 2006 Kia Sorento presents a mixed reliability profile. Owners should be particularly aware of potential issues with the V6 engines, specifically concerning the timing belt on the 3.5L and timing chain on the 3.8L, as failures can be costly. Automatic transmission problems, such as harsh shifting and leaks, are also noted. On the suspension, worn components like ball joints and bushings are common wear items that require attention. Electrical gremlins, particularly related to the Body Control Module, can lead to frustrating intermittent problems. Exterior rust can be a concern depending on climate. While not a perfect vehicle, addressing these known issues proactively can help maintain the Sorento’s functionality and value.
