My brand new 2004 2500HD, Duramax (LLY) is at the dealer due to engine hesitation between 1600-2000 RPMs. The dealer states that the EGR valve must be replaced. The truck only has 1,000 miles on it. Has anyone else had this issue? Is this a wide spread problem?


I hope this is not a sign of more trouble yet to come. I tow a 11,000# fifth wheel and don't need these type of problems on the road.Edited by: groten

I picked up the truck on this past Friday after three days in the shop. EGR was replaced which seemed to solve the problem.


The only problem is now I have an oil leak dripping near a sensor in the bottom of the oil pan and near the front of the transmission. Any had this issue before.
