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

Reliability score : 7.8/10

The 2nd generation Chevrolet Colorado (codename GMT31XX for North America) marked the highly anticipated return of General Motors to the midsize pickup segment. Positioned below the Silverado, it stands out with an excellent compromise between utility capabilities, ride comfort, and dimensions suited for daily use. Unlike the global version (sold in Asia and South America since 2012), the North American version launched in 2015 benefits from a specific chassis, dedicated gasoline engines, and a more plush interior. It received a mild facelift in 2021. Overall, it is a reliable model that ranks in the upper average of its category, offering a more comfortable alternative to the Toyota Tacoma, although the early model years (2015-2016) suffered several early recalls.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The 2nd generation Chevrolet Colorado is an excellent choice in the midsize pickup category, offering ride comfort that is often superior to its direct rivals. The 2.5L gasoline and 2.8L Duramax diesel engines are the true stars of the lineup in terms of reliability, showing excellent long-term records. The V6 is high-performing but requires more rigorous maintenance. Buying advice: Avoid the 2015 and 2016 model years if possible, as they concentrated almost all the recalls (steering, airbags, brakes). Favor a model from 2017 onwards. If you opt for a V6 (2017-2019) equipped with the 8-speed automatic gearbox, demand proof that the transmission fluid change was performed with the updated GM fluid to avoid torque converter issues.
