Summary

The 2010 Toyota Prius, while generally reliable, faces some common issues. The most significant concerns are related to excessive oil consumption, hybrid battery failure, and combination meter failure. These issues can be relatively costly to repair, particularly the engine work and battery replacement. Other issues, such as the inverter coolant pump and rear shock absorbers, are less severe but should still be addressed.
