Manifold/header/muffler/tail Pipe problems of the 2005 Chevrolet Tahoe

I heard a ticking noise in the engine compartment, upon investigation of where the noise was coming from, found a exhaust manifold bolt missing. Research indicates this is a common occurrence on these type vehicles.

The contact owns a 2005 Chevrolet Tahoe. The contact stated that two of the rear exhaust manifold bolts sheared off on both sides of the engine. The vehicle was taken to the dealer. The technician stated that the bolts had to be drilled out in order to be replaced. The manufacturer and dealer were made aware of the failure. The vehicle was not repaired. The failure mileage was 98,000. The dealers explanation was an aluminum head versus a cast iron exhaust manifold versus case hardened bolts all expanded and contracted together, which cause a poor design. Updated 08/18/14.

My bolts on my exhaust manifold are breaking off. I have five grand kids that ride in my truck at times. I don't want carbon monoxide coming into my truck. These bolts should not just break off, this is an expensive repair and should be recalled by the manufacturer. I have seen where this has been an on going issue with chevy and gm trucks. This truck was build with family in mind. Now because of this issue myself and my families safety is at risk.
