When slowing down and then accelerating afterward while in traffic the vehicle does not down shift to the correct gear. the vehicle will then sputter and will be very sluggish to accelerate. this happens while in motion as well as from a complete stop. i was nearly rear ended while making a right turn into traffic and the truck would not find the correct gear and thus would not accelerate enough to get out of the way from oncoming traffic. several times i thought that the truck was going to kill because it was sputtering so much when in the incorrect gear. truck also wobbles more than usual when turning and makes a popping sound in a turn. also, radio acts like it has a mind of its own. navigation will go haywire as if someone is touching the screen, but no one is touching it. radio will change channels on its own and volume will increase and decrease without any driver input.
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.
