Summary
The 2004 Kia Sorento, while offering value and capability, has demonstrated several common issues. Engine problems, particularly timing belt failure on the V6, can be very expensive to repair. Transmission issues, specifically with the 4-speed automatic, are prevalent and may require costly repairs or replacement. Suspension components, like ball joints and shocks, tend to wear prematurely, necessitating replacements. Electrical and interior issues, while less critical, contribute to overall ownership costs. Rust is a significant concern in certain climates, and addressing it can become costly. Overall, potential buyers should carefully inspect the vehicle for these issues and budget for potential repairs.
