Well looks like I may have a serious problem ahead of me my 2013 xts4 just today began with the warning stabilitrak like as well as the traction control off and on by it self . My speed and RPM gauges also started jumping up and down all crazy . Please anyone any advise on the resolve . I also researched this problem in general and seems that gm has a manufacturer error that they have not corrected yet mostly ok n the trucks also my hooe is that just over a hundred thousand miles it isn't unfixable.
