**beware** I own a 2014 GMC Sierra denali that abruptly shuts off on me while driving with no warning. I took in into the delearship and they stated that they fixed it. About a little over a year later it started acting up again off and on. I didnt want to deal with the dealership because they always say "it is not covered under warranty" although it only got worse. I ended up taking it back to the delearship recently because it got to the point where my truck was shutting off on me every day in the middle of the road. This was an accident waiting to happen! the dealership after over one week finally found that it is an electrical harness issue, sending the wrong signals causing my truck to abruptly shut off. They are charging me over $900. This should be a recall! how in the world is this not covered through GMC! I will never purchase a GMC vehicle again.
My 2014 GMC Sierra shuts off while driving on the interstate with my family. In some cases all electrical blinks and it continues to drive while temporarily losing power steering and other features and other times turning off completely until coming to a stop. The dealership wants ~$400 to do diagnostics on a g218 bolt that they were told by GMC that it is related to. This issue came from the factory this way. While not wanting to pay that for the diagnostic and researching myself, I found 100s of videos online similar to the one below which shows this issue happening to owners of the GMC trucks. When I spoke with GMC customer care about this, they told me that there were no recalls on the issue. There are going to be truck owners that lose their life along with any passengers if this issue is not taken care. I am very scare for our safety and the safety of countless others like the link below have posted about this known issue. . Read more...
The truck dies at any moment. Stability track system warning pops up in the little screen and the steering wheel is blocked when this happen. After these to things happens the truck shut down. Sometimes, after a few minutes the truck comes back to normal. This has happened to me for like 10 times in a period of like 15 months. I have taken to the dealer like 6 times and they haven't found the problem. They have change some wires from the battery. They have reprogram the software and nothing I still have the same problem. The truck dies at any moment. All of this happen when I am driving the truck most of the times at low speed and while turning to the left or right except like two times that occurred while I was driving in the highway. The mechanics in the dealer have done all kind of diagnostic that they have but they could not duplicated the problem so the answer that I get every time is that every is fine and that they couldn't duplicated the problem.
There is a extremely dangerous electrics issue with my 2014 GMC Sierra 1500 all terrain. In the last 18 months my truck has locked the steering at low speed while turning 8 times. (I could have easily broken a finger a lost control of my truck) . On 5 of the times I had steering issue the truck had no power to anything including key fobs for a period of 10 to 15 minutes. Then the truck will power up again. Fortunately these issues have occurred at low speed. This has happen 8 times in the last 18 months . It has been to dealership for service regarding this issue they changed the battery after only 18 months (10/2015) the issue occur again 2 days ago while traveling on the freeway at 70 mph my truck shut down no power then in less than a second it powered up again all the setting on my radio, climate control changed. That day I stopped to get gas got back in my truck pulled away from the pump the steering locked truck shut down again for 20 minutes. This truck is currently at a dealership they still can not diagnos the issue. I'm extremly concern that someone could be seriously injured or killed if this was to happen while operating this truck. I did see that may other owner of GMC Sierra have expressed similar concerns. The issues needs to be addressed immediately. As for myself I plan to this truck after the dealership attempts another repair.
