What was the problem did you ever find out?Interesting. This just happened to me this morning. Got in, started it up, and the check engine lite was on and also the trac control Off light was on. First thing I did was check the gas cap. It was loose. tightened it up and drove to the dealership. The dude double checked my gas cap, told me to drive about 30 miles and the lights might go off. So that's what I did. Except as I was driving I also noticed my eco light was not working. So I turned around and will be calling the dealership as soon as I get done here. Hopefully all these things are interconnected somehow. I hoping if they just clear the light everything else will clear up too.
