When I was driving back from vermillion to Sioux falls with my girlfriend tonight, my traction control light came on as did my hill holder light at cruising speed on the interstate. This is the second time it's happened to me in several days, but it happened right when I got into third gear on the on ramp today. When it happened the other day, after I had turned the car off, the issued resolved itself. The vehicle is a 2008 wrx with about 41k on it. Any help is greatly appreciated!!
