So randomly although seemingly more frequently it has momentary power failure and then shows service stabilitrak, or service trailer brake system will usually make the yellow abs and traction control lights come on in the console as well as show traction and stabilitrak toggle on / off in the message window. Have been to our local Chevy dealer multiple times as well as a couple trusted mechanics with nothing to show for a lot of money spent!! For whatever reason it doesn’t throw out any codes when it has these little conniption fits. Any advice would be greatly appreciated it!!
