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).
Forester
Overall
Overwhelmingly positive sentiment across multiple generations, with the Forester consistently praised for its practicality, safety, all-weather capability, and long-term reliability when properly maintained. Owners express deep satisfaction with the vehicle's spacious interior, excellent outward visibility, and the effectiveness of its standard all-wheel-drive system in snow and poor weather conditions. The vehicle is frequently described as a dependable, no-nonsense family hauler and outdoor companion.
Best version to buy
For the 2019-2024 generation, the Premium trim is frequently cited as the "sweet spot" for comfort, convenience, and price, especially when purchased used. For the new 2025+ generation, the hybrid model is specifically recommended by some owners due to its different (non-CVT) transmission and improved technology.
Known issues
- CVT transmission longevity concerns: Concerns about long-term reliability beyond 100,000 miles, with strong owner consensus recommending proactive fluid changes every 30,000-60,000 miles despite some manufacturer guidance.
- Infotainment system glitches: Occasional screen freezes, slow response, or connectivity issues. Noted as an annoyance but not a dealbreaker. Frequency: recurrent.
- Windshield/glass cracking: Described as an "Achilles' heel"; prone to cracks and chips, necessitating comprehensive glass insurance. Frequency: recurrent.
The verdict
The Subaru Forester is the better choice for most buyers.
It has stronger reliability sentiment in owner reports than the GMC Terrain, based on the data above. If the specific known issues on the Subaru Forester are a dealbreaker, the GMC Terrain is worth a closer look instead.
