Summary

The 2004 Volkswagen Jetta can be a rewarding car to own, but it’s essential to be aware of potential issues. Engine problems, particularly with the 1.8T (turbocharger and sludge) and the electrical system, represent the most significant concerns. Transmission issues are also common, especially in the automatic transmissions. Suspension components like control arm bushings are also prone to wear. The cost of repairs can range from relatively minor (sensor replacements) to substantial (turbocharger or engine replacement). A thorough pre-purchase inspection is highly recommended.
