Need help with Low trac light coming on...

I pull out of the driveway, no hill, its pretty flat and i got to turn my wheels to face looking down the street and as i trun the wheels the low trac light goes on and then back off then on again, one day, it went to trac off, low trac, brake, and service vehicle soon. I turned it off and restarted it and it was fine. What would be causing this?? I have new tires, less than 20,000 on them, Eagle GTHR's, brakes are great the car is exceptionally sound, cept i have 163,500 on it..
