Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

My 2015 Colorado Z71is experiencing moderate to severe hesitation concerns. It's progressively getting worse. I first brought it back to the dealership to have it checked out around1000 miles, 6000 and now 20000. Each time they claimed they can't do anything because the diagnostics reveal no trouble codes, although, per aforementioned bulletin, there's proof that a problem exists. I inquired if it could be a mechanical issue, but they refused to because no diagnostics produced no codes/proof.

Vehicle looses accelaration on take off it., not all the time you don't know when its going to happen. This is dangerous you have to be very careful when pulling out from stop position or changing lanes the truck will loose accelaration.I have almost been involved in an accident because of this. It will also buck as you are going down the road. I have had it back to country Chevrolet several times and they have asked me to work with them a lot of times it was never documented. The vehicle is going to get me or someone killed. This truck started this from day 1

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.

When connected to any android device the steering wheel controls upon pressing the back skip button bring up a large error box on the mylink display stating that function is not available. The actual skip backwards takes place and does indeed work but then you have to take eyes away from road to hit button on screen to clear error box, thus making the safety of using the steering wheel control button pointless. All other skip backwards buttons onscreen and below the screen work fine with no error. This has been tested on multiple android devices and regardless of the device or version number causes the box to display when using the skip back button only on steering wheel. Scanning bluetooth inputs coming into device show all 3 buttons (mylink display, below display, and steering wheel) send the exact same command to the android device and work. But some reason the actual mylink software is reading the steering wheel back button as also asking for something else that brings up that error box.
