Exhaust manafold bolts are breaking off for no apparent reason. I have four broken already and an exhaust leak developing. This appears to be a defect in manufacturing. I have a friend with two of the same trucks that the same thing has happened to. There are numerous complaints posted on the web. I have had many vehicals over the years and worked them hard but have never seen a broken exhaust manafold bolt on any of them. This can be a dangerous situation as having exhaust leaks under hood could cause a fire. As far as I know gm has not issued a bulletin or recall on this but there should be some remediation as this is an expensive repair and it is not a failure caused by the lack of maintenance. I have also heard reports of repaired units breaking again in about the same number of miles and having to be repaired again.
