For well-maintained examples, particularly older models (pre-2012) and newer ones (2022) purchased new with warranty, owners report high satisfaction, praising the car's simplicity, excellent fuel economy, ease of DIY maintenance, and surprising interior space for a subcompact.

Rio
Overall
Sentiment is mixed and highly dependent on generation and purchase context.

Long-term owner reports indicate satisfaction with its role as a simple, dependable commuter car, with some examples reaching high mileage (e.g., 262,000 km, nearly 300,000 miles) without major powertrain issues.
