When driving the truck it shuts off and then it turns back on. The stabilizer light goes on. It has happened many times while driving and also when backing up. I need to know any specific information why is it doing it, I have taken it to the dealership and they never have found the issue.

The vehicle is stalling when braking and getting ready to turn. My truck is showing stabilitrak service intermittently and I've almost been in a crash 3 times because of this. The vehicle only restarts after placing in park. This is not safe when in traffic. There seems to be no recalls and no known cause. Someone is going to die if GM doesn't fix this. I've been on forums and it's a common problem. It should be fixed by GM if it is so common. This happens when approaching cross traffic at an intersection and I lose all control of steering braking and power to the truck.

Brake pedal or that increased effort is needed to depress the brake pedal. Also, in some cases a tick or ticking noise may be heard, which may sound like an exhaust manifold leak.

Truck has 3 problems that can put my family's life in danger. 1- sometimes out of nowhere at low speeds when you turn the steering wheel to make a left or right turn the 'stabilitrac' light flashes in the screen and locks and won't let you turn the steering wheel.at this point you have no control of the steering wheel, it locks and bounces back at you and if you keep trying to turn it, the engine cuts off all power and it stalls, just dies. I almost got read ended a couple of times already due to this problem. Just this morning I was making a right onto a local mcdonald's and the steering wheel locked and the engine died on me. I had to quickly turn it on again and keep going.another time it happen as I was merging into traffic. Very scary! problem number two, I think its just a matter of time before the steering wheel locks on me on high speeds. Sometimes when I'm on the freeway, the same chimes come on when I step on the brakes, the center screens goes black, and the same 'stabilitrac' warning comes on the smaller screen behind the steering wheel. I'm afraid to take it on a winding road for fear that the steering wheel will lock on me cause an accident. 3- service brake controller sign and chimes come on ant won't go away. It jus keeps on popping on and on and on and they go away when you turn off the truck, and come on again months or weeks later. I did have it checked at my local dealership.they tested it, sold me new ground and hot wires. It was good for about 4 weeks before the same problems came back again. I did some research on some of the forums and you tube videos and by far I'm the only one with the same problem. Very afraid to cause an accident.

While at low speed and at stops while turning the wheel the entire dash and engine cut off and come back on. The steering also locks up to a point of not turning either way. All incidents happened on a very smooth flat road. This put my life in danger on one occasion while turning on a highway where my entire truck shut off mid turn.I have video of this occurring on my phone if you would like to reach out to me for that. I believe this to be a stabiltrac issue, one of GMC's traction control branding things. I have seen this issue all over google while searching it and it needs to be recalled! I would like to know if this will happen.

Loss of power steering assist, steering wheel jerks or kicks back when turning, messages with warning chime appear on instrument panel which also goes blank or inoperative, engine stalls and dies. This happens while vehicle is in motion on city street or hwy I10 (in bumper to bumper traffic) and when turning or backing up into a parking spot. This has happened before but more recently lately (at least once a day since 9/16 -9/18/2017)

Has had an issue with accessories flashing off and back on. Reported it to a GMC dealer and they were unable to duplicate but said that the battery was bad and most likely what was causing it. It did fine for a while then began doing it again. This time however it caused a loss in power steering and I ended up in the ditch. Later it did it in a parking lot and was able to video tape it. Took it to the dealer and showed them the video. They were unable to duplicate for 4 days while I was paying for a rental because mine wasn't safe to drive. On the fourth day I provided them with a service bulletin I found that addressed the issue as being a fluctuation in power and for them to check the cables and do a drop load test. They did and it failed. I then had to pay $376 to replace them plus having to pay for a rental after asking for a loaner. This is a problem a lot of people are having. Just a quick google search makes that plain. GM isn't wanting to admit it. I have the video but I don't think it will allow me to upload it to the form.
