Passenger side exhaust manifold bolts rust and break off on all gm full size trucks. I have 2004 silverado 2500 hd with 61k miles, problem started at 56k miles as a mild tick that went away when engine warmed up and progressed to constant leak when engine was under load , two rear exhaust manifold bolts broke off causing exhaust leak. Seems all truck engines have this problem from 1999 -2007. This sounds like a manufacturing defect that should be addressed by gm .

Exhaust manifold bolts breaking off. Almost everyone I know is having this problem with the v8 gm engines. Leads to exhaust leaks, sensor failures and bad catalytic converters- thus failing emissions testing. Hard and expensive to fix.

I experienced a sudden loss of engine power while travelling at highway speed. I am the original owner of a 2004 chevrolet silverado 2500 four wheel drive with the duramax diesel and allison transmission. On sunday, october 4, 2015, shortly after a fuel stop, I was traveling on interstate 24 near paducah, ky. At approximately 65 MPH in the left lane with the cruise control set, I experienced a sudden loss of power accompanied by a loud engine rattling, and the check engine light came on. With some difficulty in heavy traffic, I was able to maneuver to the right shoulder of the road. I was able to drive the vehicle at about 25 MPH on the shoulder. Since I was just a few miles from the paducah exit, I limped there and into a hampton inn parking lot. Aaa responded and towed the truck to royal oaks chevrolet in paducah. Since it was a sunday, the service department was closed. The next morning, the dealership's service department pulled up codes po202 and p2149. The service manager reported that there was a service bulletin on this issue and that it would be several days before the repair parts would be available. I later learned that the service bulletin is #05-06-04-047c. The bulletin addresses "a severe reduction in engine power (limp home mode)" I was charged $1,076 for repairs for a known defect that chevrolet knew about.

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.

In wyoming, traveling i90 to hyw 16 mountain pass...7 per cent grade....after two miles engine overheated and had to pull over to let engine cool down...had to take another route to bypass mountain. Googled duramax overheating and found this was a very common problem on the 2004 duramax diesel..design problem prevented adequate air from entering engine...should have been a recall or at least gm should have offered a solution...

The bolts are braking off the exhaust manfolds and the manifolds are leaking and the computer is making the truck go into reduced power.
