it was cold the other day and the dash flashed the ice warning while driving. the next day when I started the car the service ESC came on and the little light with the car and the triangle was on. the was the case for the last 2 days, just now I had to run out and no warning and no light, but it is 50 degrees now. any ideas?

 

Pull the codes. Certain CEL codes will disable functions like ESC and traction control (lights probably came on because the system was in disabled mode )
Post back the results and we can proceed with advice.
