All happened same day. Was 8 hours from home and pulling into parking spot and the brakes went to the floor 3 times. Has not occurred since. But when that happened the air started blowing warm and the service driver assist came on briefly. Still air is blowing warm and the service driver assist comes on. Have never had a check engine light come on. I am having it checked out this week.

The vacuum assist pump on my 2014 GMC Sierra went out suddenly during my morning commute. The brake pedal became very firm and the brakes were unresponsive. If I had been driving in an congested area an accident would likely occur.

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.

We had the vehicle recall notice about the stability and power assist repaired at our preferred GM dealership, james wood, before the problem occurred because of a recall notice we received last year. Sunday, January 30, 2018 the dash displayed power assist limited and also displayed ABS light. Service engine soon, so we brought it to the dealership again. This time the vehicle was revving high but no display. The dealership observed the vehicle doing this but we were told the recall had already been performed. There is a revised product safety recall reference number N172085440. I'm alerting the NHTSA of this.

When driving the truck after extended periods of time (I.e. 1 hour or more) the vehicle will flash a stabilitrak warning and then power the vehicle off. This happened while my son, girlfriend and I were on a trip to Florida driving 70 mph down the interstate. I took to a dealer and they informed me that the battery cables were loose. 4,000 miles the truck has done this episode again and the dealer now tells me that I need to replace the electronic rack and pinion on a truck with 65K miles with a cost of over $3K. There are numerous examples of this happening with trucks just like mine and GM isn't responsible? hard to fathom that in the 5 vehicles I have owned, not once have I had to replace a rack and pinion and the newest vehicle that I have every owned has this issue.

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.

I temporarily had no control over the vehicle causing me to have an accident. While driving down a residential street approaching a stop sign intersection I merged into the center of St to pass a trashcan and in the process of returning to my correct position on the road I suddenly had no steering. Panicking from the loss I pressed my brakes an attempt to bring vehicle to a stop but was unsuccessful because the tires began a slide once noticing the traction loss I proceeded to release brakes and reapply in hopes of gaining traction the brief relief from brakes caused the vehicle to regain traction and while I still have no control over steering, the vehicle jerks towards the right side of the road and the brakes being reapplied the vehicle continues to slide off pavement making contact with stop sign and telephone pole.

On or about 4 April, 2017 I experienced an alarm while driving my 2014 GMC Sierra. While traveling between conroe tx and plano tx, I received a warning steering stability. The alarm cleared so I checked my owners manual and it said to take it to a dealer if it didn't clear. I used onstar and had a diagnosis done on the truck. They reported no problems. The next day the truck shut down, in the middle of making a U turn. My daughter thought she had knocked it out of gear but couldn't get it to start until she turned it off and back on. The same thing happened again (this time to my wife) turning into a parking lot. She took it to a GMC dealer to have it checked out. They found a broken gear in the electronic power assist assembly. We heard that our vehicle had a recall # 17276, for problem with the steering. I then took it to the dealer where I bought the truck and had the computer updated to prevent the problem. I then ask for a reimbursement for having to have the steering module and negative battery cable replaced. I contend that, at the time, the cause of the steering problem causing the truck to die. When I ask a technician at mckinney if the recall was for the problem, he said: No that is just to change an error in the computer. Back in April, the only thing they could do to possibly prevent the stalling was to look for something like a power problem. Before I took the truck in I had no indication of power problems and I was never told how the negative battery cable went bad, only that it happens and the truck was out of the 36 mo warranty. I checked on the internet to see if anyone else was having the problem and what the solution to it was? I saw several people were having the problem, but nobody knew what exactly caused it. The consumer requested to be fully reimbursed for the repairs made referencing the recall #17276.

Yesterday I was driving home on the highway driving approximately 75mph when without any warning a stability steering control light flashed on the dashboard behind my steering wheel. The car immediately jolted from driving mid 70's down to an immediate 67mph. This speed limit was the last thing that flashed before my dashboard blacked out, the steering column locked and the vehicle entirely lost power while driving. Seconds later my windshield wipers sporadically started moving (I did not engage the switch) and I watched the temperature go up from 70 to 80 without touching the gauge manually. The car jolted for almost 10 miles sporadically losing control intermittently and when I exited off the highway and made a left hand turn at a low speed (under 15mph) the steering completely locked and the car pulled off to the side of the road toward a curb. I gained control of the vehicle manually which was difficult but I did correct the drive path back onto the road. I pulled into the dealership at a low rate of speed and the car did the same thing as it did when I exited the highway. I'm in a loaner and the dealer has my vehicle. This vehicle was purchased used roughly 2 months ago from a registered GMC dealer with 40K miles on it. It now has roughly 44K on it. I have made 1 payment on this vehicle thus far.

When I turn the ignition to start the vehicle, it acts as if the battery is drained. Then there's a message that pops up briefly stating "stabilitrak". I'm concerned this is about to get much worse. The vehicle was stationary at the time of the message.

In the past 4 months, beginning at about 52K miles, I started receiving messages on my truck that said "stability control" was out and it locks the front left wheel, losing all steering, the radio and then the truck goes completely dead. The ac goes on/off and the headlights flicker. This is always at low speeds between 5-10 mph and most commonly when making a turn. I had the battery replaced at the dealership and now they're telling me I need a negative battery cable replacement?
