Is the ABS light also on? That should indicate a ABS / Trac control problem, maybe a lost wheel speed sensor signal. To figure out for sure it has to be diagnosed with an OE or similar diagnostic computer.

No, the ABS light is not on. I had brakes and rotors replaced within the last two months, so I am thinking wheel speed sensor. The lights went off yesterday and have not returned, so I am thinking this is definitely just a sensor. Thanks for the answer!
