Head gasket failure: A known issue on higher-mileage examples (typically above 150,000 miles) related to the shared Prius 1.8L engine. Can be a costly repair. Frequency: recurrent.
Excessive oil consumption: Linked to piston ring wear on high-mileage vehicles, with one report of burning 1 quart every 1,000 miles. Frequency: isolated.
Hybrid battery aging: Acknowledged as a potential long-term wear item with replacement costs around $2,000 (USD), but batteries are reported to be very dependable, often lasting well beyond 200,000 kilometers. Frequency: recurrent (as a consideration, not a widespread failure).
