2014 GMC Sierra 1500 Vehicle speed control Problems

“I was driving down the road and all of the sudden it was if my transmission disengaged and my car lost power. It then automatically came back on and the 'service stabilitrak' lights came on. I nearly avoided an accident and was able to pull off onto the side of the road.”

“I was driving on the interstate and a message stating service stabilitrack message appears simultaneously with the check engine light and service traction control, the car loses the ability to accelerate and maintain speed. I kept driving because there was no safe place to stop, and after a few miles the door locks unlocked then locked, the info screen flashed and then the engine revved and appeared to drive normally. Several miles later it happened again, over and over. When I reached my nieghborhood the car completely powered off.”

“Mark porter GM superstore in pomeroy, oh sold me a new truck with unresolved recalls in december 2014, one being GM recall 14192. The engine in my truck failed on january 1, 2015, and the recalls were disclosed to me when the truck was towed in for repair, approximately 2 weeks after purchase. The aforementioned safety recall is in reference to a potential transfer case selector malfunction. After repair of the recall, I had a malfunction of the transfer case selector, except it became stuck in 4 wheel drive, instead of shifting to neutral. …”

“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. …”

“Complete loss of power steering along with speed control being disabled when a turn signal is activated. Recall 17v414000 has already been completed and did not correct the problem. Both of these issues occur during the same drive cycle (issues have not happened simultaneously but will both occur at some point during the same drive cycle) they seem to only happen on drive cycles that last longer than 45 minutes.”
