Summary

The 2007 Toyota Prius is a generally reliable vehicle but is prone to some common issues. The most significant concerns are related to the hybrid battery, inverter, and brake actuator, which can be quite expensive to repair. Other issues, like suspension sagging and combination meter failure, can also add to the ownership cost. While the Prius offers excellent fuel economy, potential buyers should be aware of these potential repair costs.
