Summary

TSB: EV AND HYBRID A/C SYSTEM SERVICING REQUIREMENTS - The Soul Electric Vehicle (EV) and the Optima Hybrid use an A/C compressor that is driven by a high-voltage electric motor rather than by a belt. Both the motor and compressor are in one housing with a mix of refrigerant and oil flowing through both sections. Because the oil flows through the motor windings, it must have a high electrical resistivity (low conductivity).

Owners of these vehicles have filed 65 complaints in the electrical category.
