There were no previous issues of any kind until I tried to leave work one day. Two warning lights came on when I started the vehicle: "Service Power Steering, and Service StabiliTrak, drive with care". I tried backing out and could NOT turn the wheel. I had it towed to a mechanic the following day and found out that other 2015 Colorados have a recall on this exact part. Power steering could have gone out at any time while I was driving and the weight of the vehicle could have caused a serious accident, depending on when and where it happened, seeing as how I could not budge the steering wheel. I contacted Chevrolet and was told my vehicle "wasn't covered" under the recall. They had no desire to assist me in any way. The mechanic I took the truck to is having trouble ordering the part because it is on nationwide backorder. I wonder why? If they can even fix it, it will cost me close to two thousand dollars at this point, for a safety issue that should be covered by Chevrolet. Please help get this recall extended to every 2015 Colorado before someone dies.

A factory bolt that is not checked up routine maintenance/inspection came loose and caused significant damage to the rear axle of our truck. GM's customer service did not feel a need to cover the costs of this manufacturer error when the bolt should not have come loose in the first place. Please see attached complaint for further details.

Key has been sticking in ignition, unable to remove. Ive kept the key in the ignition and the battery has needed jumped. Dealer tells me this is a very common problem on Chevy Colorados from 2015 and 2016 as I have now discovered on multiple Chevy forums.

When put vehicle in park I am often unable to remove the key from the ignition. I have to restart it & move steering wheel to another position. Often have to do several times before I can get key out. Dealer said there are complaints with vehicle being put in park & they said to move shifter in/out of park to get it to work. I can not figure out if shifter or steering column.

While backing up my driveway glanced at the backup camera.it appeared to have plenty of distance left between the rear or car and the garage door. While at a very low speed, without notice, the truck hit the garage.it went from what appeared to be several feet to making contact with the garage instantly. No sensors, lights or alarms went off. No warning what so ever

I'm constantly receiving the message "service power steering drive with care" then afterwards I receive the message "service stabilitrak". this message has continued to occur at random times while driving on a highway while driving 70+ mph. The steering wheel locks up and I have to physically strain to power the wheel to turn and pull over to shut the vehicle off for 10 seconds then turn it back on and the problem is gone. However the power steering continues to go out again at random times while driving lower speed limits through city streets. The problem with the power steering is continuous. I'm also having issues with the temperature control. My trucks heat will go out and only produce cool/cold air at random times. It will work then the heat will go out at random times. I have the gauges set to hi heat with full fan output and it only produces cool air. I'm unable to properly defrost the windows during cold temperatures due to lack of heat. Defrost fan options output is inaccurate as it can be on high output and turned one notch down and the fan speed is consistent with the lowest fan speed.

2005 Chevy Colorado rusted frame next to rear cab mounts on both sides. Frame is cracking in this location. This appears to be the result of rusting from the inside out because the rest of frame looks to be in good condition. Still has paint on it. I think this is a weak spot in the frame due to a structural engineering issue. I have found many other people complaining of the same problem with there Chevy Colorado's

We purchased a new 2015 Chevy Colorado in January 2015. On March 3, 2017, my son heard the truck start and run while he was sleeping. The truck is in the garage below his bedroom. I brought it dealership the next day and also filed a safety complaint with General Motors. It is approaching 2 months they have had the vehicle. During most of March and now April, mechanics, technicians, engineers from GM and a field representative tried to decipher the issue. At/around 3-22, I received a call from the service manager(andy) telling me, they "think" they found the problem. I let him know I would not take it back without at least 100% assurance it was solved. They decided to keep another few days and drive it. I have also talked extensively with GM customer service. They have said, they will not help in any way.

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.

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.
