I'm late coming to this thread so maybe this has been brought up about the Duramax. A friend of my dads was at a dealer getting his truck serviced and noticed a row of "newer" heavy duty trucks out back. When he spoke with a friend of his in the service department he was told they were all traded back due to problems with the new diesels. He said the DEF fluid heaters weren't working proper and once temps got below 20F the trucks would have alarms and not run right. I saw some comments on this on another truck forum I sometimes go to after he told me about it.
I love diesels and always wanted one, but the newest ones they put in trucks I don't trust. I have heard Ford and Chevy were having some fuel injection issues. I know a few people with these with problems and read of more on-line. 2 of the engines were in local EMT vehicles, one Ford and one Chevy both only about 1 year old. I know Cummins has had issues with the EGR in every engine they make from the small ones in the Dodge trucks to the large ones in heavy trucks. Not every one, but enough problems that I just can't see spending thousands more and take a chance on having problems.
Now it is possible these problems are over blown, just some food for thought before you buy.
