The short answer
Based on available data, the Nissan Rogue comes out ahead of the Mazda CX-50 on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Mixed sentiment with a clear distinction between powertrain choices. The CX-50 Hybrid is widely praised for its excellent fuel economy (38 MPG combined), strong acceleration (0-60 mph in 7.6 seconds / 0-97 km/h), and the proven reliability of its Toyota-sourced hybrid drivetrain, which is considered "bulletproof." The gas-only models, particularly the Turbo variant, are acknowledged for being quick and fun to drive but are criticized for poor fuel economy and a harsh, uncomfortable ride. Significant and recurrent criticism is directed at the vehicle's build quality, fit-and-finish issues, and general reliability stemming from its Alabama, USA manufacturing plant, with multiple reports of various glitches, faults, and premature wear.
Best version to buy
CX-50 Hybrid (Premium or Premium Plus trims). The hybrid powertrain is overwhelmingly recommended for its combination of fuel efficiency, adequate power, and the exceptional reliability of the Toyota hybrid system.
Known issues
Overall
Sentiment is sharply divided by generation and powertrain. For models from approximately 2011-2020 equipped with the 2.5L four-cylinder and traditional CVT, sentiment is overwhelmingly negative, dominated by widespread and severe concerns over CVT transmission reliability, which is described as a notorious, well-known failure point. Long-term owners of these generations report transmissions failing between 67,000 and 130,000 miles, with associated high repair costs and dealer warranty disputes.
Best version to buy
Insufficient owner data available to declare a consensus "best version." Discussion indicates the current generation (2022+) is preferred for its redesigned interior and updated features over older models. There is no specific trim level repeatedly endorsed; focus remains almost entirely on powertrain generation.
