Summary

The 2006 Chevrolet Optra is prone to a variety of issues, primarily concerning the engine (sensor failures, thermostat issues), transmission (harsh shifting/slipping in the automatic, difficult shifting in the manual), suspension (bushing wear), and electrical systems (power windows, door locks). Rust is a significant concern. While individual repairs may not be excessively expensive, the frequency of these issues can lead to a relatively high overall cost of ownership. Severity ranges from minor inconveniences to potentially major repairs, especially with the transmission.
