Is there a fix? Manufacturer service bulletins

What owners are reporting 1 most recent
I have two cracked exhaust manifold bolts. I have read that thousands of similar vehicles have this same condition. I have an intermittent check engine light that it won't pass emissions. I am also worried of where it is located, that it may cause a fire. I would think gm should have an obligation to fix this defect due to the epa violation & safety risk that it posses. *tr
