One problem related to engine exhaust system has been reported for the 2005 Chevrolet C/k 2500. The most recently reported issues are listed below.
The engine oil cooler lines and the transmission cooler lines leak at the crimp where the rubber hose and metal lines connect. After doing research online about this I have discovered it is a very common problem. Some people have replaced these lines multiple times only to have them leak a short while later. For those of us whose vehicles are out of warranty this can be very costly. I would also think that transmission fluid and motor oil contacting hot surfaces like an exhaust pose a fire hazard. At the very least the leaking oil is an environmental hazard. I have purchased oil cooler lines and am replacing them tomorrow but I am having trouble finding transmission lines.
