Chevrolet Colorado 2nd gen (GMT31XX) (2015 – 2022)

Reliability score : 8.0/10

The 2nd generation Chevrolet Colorado (GMT31XX platform) marked the highly anticipated return of General Motors to the midsize pickup truck segment in North America. Designed to offer an ideal compromise between the towing capabilities of a full-size pickup and the maneuverability of an SUV, it stood out for its above-average ride comfort for the category. The introduction in 2016 of the 2.8L Duramax diesel engine (LWN) gave it a major competitive advantage, offering exceptional torque and excellent fuel economy, rare assets in this segment. Overall, the model displays an "Average to Good" reliability level, positioning itself as a very serious and more comfortable alternative to the Toyota Tacoma.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The 2nd generation Chevrolet Colorado is an excellent choice in the midsize pickup truck category, particularly if you opt for the 2.8L Duramax diesel engine. This engine proves to be very reliable, robust, and offers unmatched towing capabilities for its size, with very few recorded complaints. The petrol engines (2.5L and 3.6L) are also good performers. Buying advice: Favor models from 2017 onwards. The 2015 and 2016 model years experienced the teething problems of the new generation with numerous recalls (steering, brakes, airbags). If you buy a V6 with the 8-speed gearbox, ensure that the gearbox fluid change was done with the updated fluid by GM to avoid torque converter issues.
