Summary Verdict

The 2003 Ford Focus presents a mixed reliability picture. While the 2.3L Duratec engine and manual transmissions are generally robust, owners of models with the 2.0L SPI or Zetec engines should be aware of potential intake manifold gasket leaks and cylinder head issues, respectively. Automatic transmissions can experience torque converter problems. Suspension components like control arm bushings and strut mounts are common wear items. Electrical issues such as window regulators and instrument clusters can also arise. Overall, the Focus can be a reliable car if well-maintained, but specific engine and transmission choices influence its long-term durability.
