Toyota Prius inverter coolant issue indicated by engine light on Toyota Prius

Some Toyota Prius owners report experiencing issues related to the inverter coolant, particularly when the engine light indicates a problem. These issues may include low coolant levels, leaks, or malfunctions within the cooling system, which are critical for maintaining the optimal temperature of the hybrid system. If ignored, these problems can lead to overheating of hybrid components, resulting in reduced performance, increased emissions, and potential damage to the inverter. Owners are advised to check coolant levels, inspect for leaks, and seek professional assistance if they cannot resolve the issue themselves. Regular maintenance and prompt attention to warning lights can help prevent further damage and costly repairs.
