I have a 2009 Saturn Aura that is saying Service ESC and Service Traction. on 2009 Saturn Aura

It usually is coming on when I am sitting at a stop light or stop sign. When I turn the car off and start it up again, the message does not come on again until sometimes days later. The car just turned over to 40,000 miles. Has anyone out there had this problem? What is going on with my car
