Transmision in this vehicle is the worst,and could be dangerous for novice drivers.I've read plaged problems with these vehicles and transmissions after I purchased it.Transmision jerky,shutters.You go to take off and it switches in to low gears too soon and causes the vehicle to vibrate.Sometimes slips between 4th and 5th gear.Also when giving a little bit of throttle sometimes vehicle acts like your flooring it,in rainy or icy weather can cause back wheels to spin causing fish tailing.Had it happen couple times.I've read torque converter problems,and some under a campaign have been replaced.This vehicle has low mileage for a 2015 (83,000)
Request to be added to any class action lawsuits with my Colorado Truck. Truck was purchased Jan 2015. On day one the truck had a shudder that was lite but noticeable, dealer said " this is normal and as the computer gets to understand your driving it will be less noticeable" I put up with until the transmission stopped working and had to replace the Torque Converter on Jan 2022 after to warranty ran out. $2788. The trunk still has a shudder issue...if the transmission temperature is less that 120 degrees the truck will shudder as your coming to a stop. Once the temperature is over 12 degrees the shudder stopes
While stopped and trying to turn left on a busy highway I was hit from behind by a driver who did not see me until it was to late. I saw him in my rear view mirror, however, barreling down at me at a high rate of speed. I hit the gas to the floor trying to get away from him but my 2015 v6 Colorado hesitated for a 1/2 second or 1 second, I don't know. It seemed like forever. It then kicked in and we got about 100' before he slammed into the right rear bumper. The impact drove the Colorado forward about 10' and killed the engine. My wife and I both hit the back of our seats and bounced forward and the seat belts caught us. Just prior to the hit, I was leaning forward and thus bounced hard against the seat and then bounced hard against the seat belts; seemingly in a very small fraction of a second. It been a year now and I still have whiplash symptoms. …

Purchased truck in November 2014. Crew cab z71. Had problems right at 200 miles. They said the transmission has to learn my style of driving. At 2,00 miles transmission and engine still don't talk to each other. I can accelerate and 5 seconds or more later the transmission reacts. In heavy traffic, a couple of cars get between me and the car I was following before it reacts and I have to slam the break. Always seems to be in the wrong gear. Will chug a lot until it gets up to the speed for that gear. Took it to dealer at oil change and they reset the control module. After 2,000 more miles, took it back because it still acted the same way. Took tech on drive and was able to duplicate all my concerns. He said that there was nothing he can do and that I needed to wait for ECM calibration from GM. He said he felt bad for me. …
My 2015 Chevrolet Colorado z71 4x4 has a serious, violent vibration at highway speed. The dealership has had the vehicle for going on 40 days.

It feels like the truck is going to come apart. …
