Toyota Prius sluggish performance with all warning lights on, hybrid battery pack failing again on Toyota Prius

Some Toyota Prius owners report experiencing sluggish performance accompanied by all warning lights on the dashboard, which may indicate issues with the hybrid battery pack failing. These owners often cite degraded or faulty battery cells as common causes, leading to diminished capacity and performance problems. Additionally, they note that dashboard alerts, particularly those related to battery issues, should not be ignored, as they can signal more significant problems ahead. Some report receiving diagnostic trouble codes like P0A80, which point to hybrid battery pack issues potentially linked to inverter problems that may also cause battery failure. Obvious signs of impending battery failure include a significant drop in the HV battery charge bar graph, especially at traffic lights, and the gasoline engine revving constantly due to battery issues. It is crucial for owners to address these hybrid battery pack issues promptly to prevent further damage and ensure optimal performance of their Toyota Prius, and seeking professional diagnosis or repair may be necessary if problems persist.
