CarComplaints.com Notes: The 2015 Chevy Colorado has a significant trend of transmission problems.
Most owners reporting transmission problems with their 2015 Colorado report sluggish shifting or other similar problems with the truck not shifting properly. Although most of these 2015 Colorado trucks are still under warranty, it's not a good sign.
The Chevy Colorado is mechanically identical to the GMC Canyon.
I have taken my vehicle to two different GM dealerships, and nobody has fixed the issue yet.
The first dealership replaced the ring-n-pinion assembly., and did a trans. fluid change, but the problem remained. The second dealership replaced a purge solenoid valve, and did a tune up, but the problem remains. This is a very frustrating problem, and the technicians cannot pinpoint if it's an engine, or trans. issue.
My 2015 Colorado truck is still at the dealership for the third time. The truck is sluggish and hesitates when downshifting. This is soooo horrible!! I was relieved to find this site and see other people are having the same problem. I thought I was going crazy.
I was told by the dealership that it was a relay module and that's just the way it is, there's nothing wrong with it, etc. blah blah blah will see what they say this time
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 too 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's been a year now and I still have whiplash symptoms. My wife was already leaning back against her seat and apparently did not suffer any whiplash. The car that hit me was totaled but the 80 year old occupant was just shaken up. He left about 30' of skid marks and was trying to get around me to the right. If the Colorado had not hesitated, I am confident he would have missed me. The hit was so hard because he hit the the Colorado's tow bar which did not bend much thus transmitting most of the force to the rest of the vehicle. For a fraction of a second the acceleration was intense.
Transmission hesitates when trying to accelerate. Took a new 2016 Colorado off the dealer lot for a test drive. Hesitates real bad when trying to accelerate especially going up ramp to interstate but around town also. I talked to dealers agent with me on the ride but he did not say a word. I won't be buying one of these.

When you let off the gas to turn a corner and get back on the gas the engine hesitates, sometimes real bad. It seems to be worse if the truck has les then a half tank of gas. Dealer said to run premium gas and injector cleaner through it, did not help. This should not happen on a brand new truck.

Chevy needs to obviously fix this issue. Vehicle hesitates and stutters at around 25 mph.
