Exhaust manifold bolts broke on both sides of engine, 6. 0 liter engine, resulting in extreme noise, poor gas mileage, service engine light blinking and smell of exhaust entering cab. Why isn't this a recall item since so many people are having the same problem with chevy and gm trucks and SUV's? the cost of repair by a garage is astronomical and it's impossible to do it ourselves. The truck now has roughly 112,000 miles since we have to use it at times.
