   I am the original owner of a 2014 GMC Sierra 1500 (VIN: [XXX] ) and began experiencing serious mechanical and electrical issues while the vehicle was still under warranty around 40,000 miles. These included engine RPM fluctuations at idle, vibrations under acceleration above 65 MPH, and intermittent misfiring — all symptoms that are now believed to be early indicators of defective lifters or valve train components. I also experienced repeated electrical failures including a…

   I am experiencing episodic loss of power steering assist without warning. This lasts for several seconds then power steering is restored. "StabiliTrak” message may be displayed during the event. On one occasion my radio also went off when my power steering failed. On one occasion my vehicle died shortly after losing power steering which almost resulted in me having a motor vehicle accident. I reported the problem to the GMC dealership and have scheduled the next available…

   The vehicle lost ALL power, completely shut off with no warning while driving. There were no warnings or anything. Was stuck for about 5 minutes and had to let cars go around me (no power and no warning lights, so could not even use hazard lights). I did some reading and it people have said this could be a problem with negative battery cable needs to replaced. The vehicle started about 5 minutes later with no issues and had to reset clock and date.

My steering wheel tightens up and I get a message on the dashboard “Stabilitrak” and another one “assisted steering reduced, drive with care”. My vehicle even shut off on me after pulling in to a parking space after turning steering wheel completely to one side
