Don't get stuck in traffic ! the trans doesn't know what it wants to do, it will shudder between gears sometimes so bad you have to hit the brakes to make it stop. Also the monitors in the center panel can sometimes change because there are switches on the back side of the steering wheel that can be touched while turning, changing your radio station, volume, and center information. Also being in the Chicago/northern Indiana/Michigan area when the temperature is below 40 after you have shoveled the drive, removed the snow from the truck, and crawl into the truck a message appears on the center screen warning you it`s cold and be careful! Also when your driving the center panel will show a message Don`t read this screen and drive distracted and you must touch the screen to make the message go away. Also under the hood is a 2ft. round piece of black plastic that serves no purpose other than keep heat in the already cramped engine bay and there are 2 useless pieces of plastic covering the right headlight , why not use this material to good use Like an ASSIST HANDLE ON THE DRIVERS SIDE!!! The truck gets great gas mileage but the Buick 217 cubic inch V6 is a car engine, not a truck engine. It does not pull well at low speeds and added to the "shudder shift six" transmission you have to play the throttle, no acceleration or sudden acceleration. The stub doors, when it is cold out, will not shut properly and you will not get a door open light until you are driving. Then the bells go off at 60mph and get worse and worse until you are able to Safely pull off the road to shut the door. If you check the lower latch will have about 1/8 of an inch play in it when it does this. The dealer says "They All Do This," and there is nothing they can do! Just make sure you push the door at the lower part and give it a pull ,if it moves shut the door again. The heated seats are to die for!!! The pickup bed is great and the foot holes in the bumper are great for getting into the back. I also change the oil and filter every 5000 miles. I use synthetic oil only. The engine is double overhead cam and the cams are the last thing to get oil pressure at startup.
I traded in my 2015 Nissan Pro4x extended cab for a 2017 Colorado z71 extended cab. I made this purchase strictly based on ratings- The dealer did not have any in stock. The front seats of the Frontier were more comfortable, and better looking. The back seat area in the Frontier was useable, but not comfortable.The Colorado is not even useable. The headlight switch and the 4 wheel drive switch on the Colorado are poorly positioned, and I have found that my legs move these switches when getting in or out of the vehicle.(No telling how long I drove around in 4-wheel drive when I didn't need it.) Also, I can't see these switches when driving. The throttle response combined with the shifting of the 8 speed transmission provide a feeling of hesitation. The back doors must be slammed hard to get the door ajar light off. The ride on the highway is car-like and smooth. I paid extra to get the Cajun Red Tintcoat exterior color, and really like the way it looks. I have only put about 750 miles on this truck, and would trade it for a new Pro4x if I could afford it.
So disappointed in our purchase of a Colorado. It came with a feature we were not made aware of. In cold weather the truck squeaks like an old squeaky bed. It sounds like a piece of junk going down the road. It is great advertisement for GM. Spend your hard earned dollars on another brand. The company has no answers.
