I personally think stress and flex have more to do with it than heat.
The dashboard is most likely screwed in too tight and the attachment points have no movement to flex back and forth, and up and down.
Combined with the fact the dashboard should have been made out of thicker plastic.
So, what you are saying is that the dash will eventually crack again? Is that it? Has GM made any improvements ever since the problem became apparent on early NNBS trucks? Meaning is the problem gone on a 2012 truck, which would mean one would have to assume that the replacement dash is made of better materials?
