One problem related to manifold/header/muffler/tail pipe has been reported for the 1998 GMC Sierra 1500. The most recently reported issues are listed below.
Service request # filed at general motors regional office #(71-448842107)intake manifold gasket leaking in all 4 corners on my GMC sierra pick up truck. Loss of anti-freeze, and possible seizure of engine. Backorder of gm intake manifold gaskets. A petition has been created and sent to gm and the better business bureau explaining . . . . As of April 10, 2002, there is a nationwide backorder of the intake manifold gasket. At this time, is it not even known when the part will become available. Being aware of this proves there is a serious problem to be addressed. Because of apparent poor engineering, gm can not manufacturer replacements fast enough for all the vehicles in which they are needed. Intake manifold leaks can lead to any number of very serious, and expensive, problems. While the part itself isn't costly, the labor to repair it is very intensive, and has been quoted around $800 usd (give or take a couple hundred depending on the vehicle). This is in addition to any other costly problem(s) the intake manifold gasket leak may have produced. We are demanding accountability from general motors. A nationwide backorder should be reason enough for gm to assemble a recall. We can only hope that the world's largest vehicle manufacturer who has been the world's automotive sales leader since 1931 will stand up and claim responsibility for a problem that is so prevalent among their vehicles. Recalls should be mandated in all cases of incompetence, not solely when it affects public safety. . Read more...
