Until the OP provides more info, we’re all just speculating at the cause, warranty , miles, etc.
could have 300k on it and be so far out of warranty or it could be a crappy dealer hosing him on warranty or it could be bad fuel and a call to the insurance company is in order.


Now why would you want to ruin a thread that is bound to explode with common sense? [emoticon]

OP, I feel for you and hope you get the issue covered under warranty or insurance.

Well know issue, so is the plastic cooling fan grenading and taking out 3 wiring harnesses and coolant lines. Also will severely damage your hood at the same time.

Well known issue, fan grenading? First time I have heard of that. Good thing your in a 92 Dodge, they never break. Crazy things happen, no matter what emblem is on the hood. There are motors that are notoriously bad, 6.5 not too good, IH 6.0 and 6.4 really bad. The Duramax is a proven engine. As is the Ford 6.7 and the 5.9/6.7 Cummins. Things happen and the odds are against it being catastrophic, even with the CP4 (like around 2% as I last read), but when it happens to you, the odds don't mean much.

I don't know if it relates but I use GM fuel filters and I let the dealer change it. I learned on an LLY 5500 that I was using NAPA fuel filters on. Lost an injector, and washed a cylinder. Related? I don't know but I have heard from engine builders when I was looking to rebuild it, that it is best to stay with the GM fuel filters. I think having documented fuel filter changes with OEM filters matters on issues like this. Just a suggestion regardless if its a GM CP4 or another OEM.

There is a new upgrade on the market for Duramax that will let you change the CP4 pump to a CP3. The article was in Trailer Life magazine, one of the last two issues. Might be worth checking out if have to come out of pocket


Not new... CP3 retro fit kits have been around for several years now.

The complete set of parts for this repair is about $3500 from InjectorsDirect, the rest is going to be about 40 hours labor. Usually the cab is removed from the chassis for this repair due to access difficulty.

Sorry, that doesn't rise to the level of a widespread issue. Not even close.

Your warning should not be limited to the 2011-16 Duramax.

Am I missing anything here?

Looks like GM is the only one to drop the CP4 in the last three years...


VW and Audi, and maybe more European cars and trucks.
