Summary Verdict

The 2004 Chevrolet Astra, while offering a range of engine options and a generally comfortable ride, exhibits some common reliability concerns. The performance-oriented 2.0L Turbo engine is more prone to issues like turbocharger failure and head gasket problems. Manual transmissions, particularly the M32, can suffer from bearing wear. Electrically, the Body Control Module and instrument cluster are known to develop faults. Exterior rust can be an issue in certain climates, and interior components like the blower motor may require attention. Despite these potential drawbacks, many owners find the Astra to be a practical and enjoyable car when properly maintained, with many issues being addressable with moderate repair costs.
