Love this truck with the bold design, ride is smooth and it has plenty of nice features. The 10 speed transmission is smooth and I love the multifunction tailgate. Very good truck.

We are the 2nd owners of this truck; have had it 2+ years and as a truck, it's co.fortable, capable and reliable. Not sure I would buy it again, though, as the electronics are a hot mess. My 2011 Infiniti is more advanced in many ways. For example - you need to PAY $40 a month if you want the Navigation to work, yet it still isn't smart enough to provide detours. Despite paying fi or a "hotspot" my phone still has to be active in the car for anything to work. And OnStar is a joke. No apps outside of two news channels and a couple of music apps - no traffic, weather, Android auto or Apple carplay. No ability to play .usic other than its own margi al sound system. Shame - a great 21st Century truck stuck in the 1990s. Bottom line, I'm not sure I would buy GM again - they just haven't caught up.
