6 months, 12k miles
Well, I said I'd be back to give a long-term evaluation of my 2016 Colorado Crew Cab LT V6, so here it is.
The Good: The fit and finish on the truck remains good. I've spent a good amount of time on the interstate commuting to work, and other than two nicks in the front, the paint is holding up very well. The interior is holding up as well, other than the seat seam on the driver side; more a result of the seat design rather than the quality of the materials I think. The ride and drive remain quite good. Keeping the tires on 35 psi is the ticket. Handling is quite steady, and steering is actually responsive, if a bit numb. Power is strong although much of it resides in the upper RPM band. The boats that I've towed (1500-2500 lbs) were not a challenge at all, and minimally affected the handing, ride and drive. Mixed fuel economy over the past 9,000 miles according to the DIC is 22.1 mpg and my best 50 mile avg. has been 27.8 mpg. Can't beat that for a 305 hp gasoline V6.
The bad: The shifting on the transmission is simply late. However, I'm planning to have that addressed by the latest TCM updates in the next few weeks. The truck has also developed the leaning condition. The dealership measured and said it was in tolerance. However, they did loosen and re-torque the DS leaf spring mounts and that cured a nasty squeak that had developed, somewhat addressing the lean. The air dam makes the truck useless off-road. It will be coming off in the spring.
The ugly: I have a love/hate relationship with the seats. Good lumbar support, but too narrow for American butts. The lack of rake adjustment for the bottom cushion should have resulted in a felony for the designers. I would happily pay 50-100 extra bucks for a 6 way adjuster. I'd also like the door storage designers to check themselves into their local jails for 60 days. I have experienced some pops and creaks that seem to be coming from other places, especially the front when turning into our uphill driveway. Not very promising given the issues with the rear.
Overall, this has been one of my favorite vehicle purchases. I would recommend this truck to anyone looking for a small, yet capacious vehicle that does 90% of what a full-size does. For the GM people checking out these forums, please have someone address the seat and door storage design issues in addition to this ugly lean. That's really all it would take to make this truck more than simply "better" than any truck in its class.
