The contact owns a 2015 Chevrolet Colorado. On several occasions while attempting to accelerate in traffic, the accelerator pedal was depressed but the vehicle failed to respond. After waiting for several minutes, the accelerator pedal was depressed again and the vehicle responded as intended. The vehicle was taken to the dealer to be diagnosed. The mechanic was unable to duplicate the failure. The contact stated that the failure recurred several times. The manufacturer was not notified. The approximate failure mileage was 30,000.

I bought a 2015 Chevy Colorado at the beginning of the year - since then I would on occasion notice a "shudder" or sluggish acceleration followed by sudden burst of rpms/acceleration. At about the 3 month mark (around 4500 miles) my transmission failed and was replaced. About a 3/4 of a month later I got my truck back and continued to notice the same shudder and erratic behavior. I began to research the issue and found many drivers of this and the GMC model are encountering the same issue. I have had to nag the dealership about the issue and there eventually was a tcm (transmission control module) software update which seem to max the issue which is beginning to manifest itself again. The short version of symptoms is as follows: Sudden acceleration at slow speeds (this caused me to almost hit a motorcyclist in slow moving traffic), odd gear shifting (or lack of) going up hills, or going down hills, sometimes turning... odd shifting at normal speeds (but normally on hills). Vibration at normal driving speeds that seems to come from under the truck (not the tires)? I'm finding the truck to be more and more unpredictable and am not sure I wont encounter another failure in the near future.
