| Broken exhaust manifold bolts. front and rear manifold bolts have broken on both the passenger and driver sides. as a result exhaust manifolds are now warping putting undue stress on remaining manifold bolts and creating an exhaust leak. bolts are steel, manifolds are cast, and heads are aluminum. dissimilar metals, heat, and moisture have caused the bolts to prematurely rust and fail. emissions dilution will not allow for a passing smog test in 2013. gmc refuses to address the issue at hand, even though this is a recurring issue on all v8 engines. estimate to repair; $2500. | |||

| The exhaust manifold bolts were broke on on side of the exhaust manifold so far. the mechanic at fw tucker and son, in, oswego, ny 315-342-0444 stated that they have replaced these on 12 trucks and after further research, i have found that there have been over 12,000 vehicles that have to had these replaced. the truck is less than 5 years old and has 54,000 miles on it. i called and filed a complaint with gmc (service request #71-827213681) and was told that they found that it wasn't a common problem and they found no indication that it was an ongoing problem, however 12,000 vehicles is an ongoing problem. the vehicle is a 2005 gmc sierra 2500hd truck. i had to pay to have the exhaust manifold removed, to have the bolts extracted, the cost of the new bolts and the installation of the bolts, new exhaust manifold gaskets and seals. i also had to pay to have the engine oil removed and the replacement of the engine oil dipstick tube. | |||
