The short answer
Based on available data, the Toyota RAV4 comes out ahead of the GMC Terrain 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
Sentiment is sharply divided and heavily dependent on model year and powertrain. Owners of newer models (2022+) report positive experiences with basic maintenance and no major issues up to 70,000 miles, describing the vehicle as comfortable and feature-rich. However, there is a very strong and recurrent narrative of significant mechanical and electrical failures across multiple generations, particularly in models from the 2010-2017 era and specific problematic powertrains in newer vehicles.
Best version to buy
Insufficient owner data available to identify a consensus "best version." Feedback is primarily organized around problematic years and powertrains rather than recommended trims. The Denali trim is mentioned but also associated with buggy infotainment and camera systems.
Known issues
Overall
Overwhelmingly positive sentiment centered on exceptional long-term reliability, low maintenance costs, and high resale value. The vehicle is consistently praised as a practical, worry-free choice for owners prioritizing longevity and cost of ownership over driving engagement or premium interior refinement. The hybrid powertrain, in particular, receives very frequent commendation for its fuel efficiency, smooth operation, and the bulletproof reliability of its eCVT transmission.
Best version to buy
The hybrid powertrain is strongly recommended over the gas-only version for its combination of fuel efficiency, smoother power delivery, and highly reliable eCVT. For specific model years, the 2016-2018 RAV4 (previous generation) and the 2019-2025 RAV4 Hybrid (current/fifth generation) are frequently cited as top choices for reliability.
Known issues
