Had the problem, 2 bows broken and top replaced 3 times. Finally got GM and my dealership to take a late 2012 top and replace the Canvas, the mechanics, and install the larger water management bag. No problems since ! I do feel the road noise is a little loud but honestly I think its me
If you think its wrong push for a total replacement not just a canvas top and a GM rep to be there for the install. They really do know how to fix it correctly.
