I have had infrequent issues with error messages telling me that I had a problem with my 2011 Suburban's Stabilitrak and Traction Control. It happened once in a while, but not often.
Now I get the messages any time I start it up and it's really hot out. On cool mornings I don't get the message, but as hot as it's been this summer, I get the messages most of the time now.

Is the heat faking an issue? Or is the issue only a problem in the heat? Or is it just always a problem?
