@dcclowdus You’re not the only one with the cracking dashboard problem; it seems that a bunch of folks are having issues with cracks in their dashboards in the GMT900 vehicles. Here some background info on the matter:

To my knowledge, GM hasn’t released any official recall or repair programs. However, I do believe that it has “helped” some customers with the the replacement (either fully or partially is another question).
Have you tried escalating the issue to (the corporate) GM Customer Service? If not, I’d start there.
