Lose Power Steering problems of the 2017 GMC Sierra 1500

Was pulling my trailer out of the water and lost all power steering, fluids full, pump working, just electrical issue. Had to drive home 20 miles without power steering, very hard to turn. They said they �fixed� this is issue in 2015, but here I am in a 2017 with the same problem, low speed and completely lost power steering, thank goodness I wasn't pulling on to a highway or in the middle of a curve.

On August 24th 2018 while driving my new 2017 GMC sierra thru west branch michigan the power steering failed and completely went out. I could barely get the vehicle off of the road safely. Steering the truck was almost impossible. I called the GMC dealer and the service department person said to turn off the vehicle, wait a bit and restart the truck. I did this and everything reengaged. A while later down the road it happened again. Power steering shut down. This vehicle is a replacement vehicle we chose after our new 2016 GMC sierra continued to shut down over 30 times with ecm problems while driving at all speeds. My wife was terrified and reluctant to ever drive that vehicle after that. After many hurdles, GMC decided to exchange the truck with our current 2017 GMC sierra that we have now. This 2017 GMC sierra has lost its power steering over15 times while underway driving. Thank god it wasn't ever my wife driving. Its bad enough for her to be a passenger now when the steering goes out as well. She is terrified, and I am very leary and concerned about this happening at any time at any speed without warning. It has also happened at higher speeds. On September 1, 2018 while making a right hand turn from m-65 on to maple ridge rd whittemore, michigan, the power steering went out again and the steering wheel whipped back to the left so hard and fast I could barely control the vehicle to maneuver. I also suffered a serious left shoulder injury that I continue to suffer with. My wife is literally deathly afraid to drive this truck. I am afraid that I may kill someone or myself and wife with this dangerous truck. While driving the vehicle to the dealer after the power steering reset after I turn it off, from the day before. It lost power steering again at 65 mph. Repairs have been made to the ecm and power steering module from dealer patsy lou williamson Buick GMC.
