Specs side by side
What owners say
Terrain
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
- ⚠Severe engine problems: Includes rapid oil consumption (burning a full reservoir within 50 miles), cylinder misfires, piston damage, and complete engine failure requiring replacement, often under 100,000 miles.
- ⚠Transmission issues: Includes stalling, failure to shift into 2nd or 3rd gear, violent jerking, and complete failure limiting speed to 20 mph (32 km/h). Reported across model years including 2016, 2020, and 2024. Frequency: very frequent.
- ⚠Electrical system failures: Includes vehicles dying completely while stopped, losing all power, battery saver mode errors, and problematic auto-start/stop systems. Difficulty diagnosing root cause (alternator, starter, battery).
CX-5
Overall
The sentiment is predominantly positive, with the CX-5 consistently praised for its reliability, premium interior feel, and engaging driving dynamics. It is frequently cited as a top recommendation for buyers seeking a dependable, well-built compact SUV. Owners appreciate its refined interior materials, which are often described as superior to mainstream competitors, and its handling, which is noted to be more car-like and enjoyable than many rivals.
Best version to buy
The consensus favors models equipped with the naturally aspirated 2.5L engine for its proven reliability, though the turbo variant is acknowledged for its added power. For used models, there is a strong preference for vehicles without Cylinder Deactivation (often found in non-turbo models from certain years) due to concerns about added complexity.
Known issues
- ⚠• **Infotainment interface dissatisfaction**: Lack of touchscreen (pre-2026) criticized as slower and less intuitive; the new 2026 touchscreen is criticized by owners who preferred the previous rotary dial system.
