You know all three have had issues with every model. Some more than others. But if you take good care of it then it will take care of you. I have a 2010 6.4L with 30k miles on it and I got it new back in June and it hasn't have had a problem once. But I change the oil every 3k miles and change the fuel filters every 10k miles. Plus I have mods done to it and I just got back from disney world and we drove and on the way there I got an avg of 22 mpg on the hwy. And my truck isn't a lightweight either. It's a F-350 CC SRW longed 4X4 with a tommy lift and it weighs 9k pounds empty. But as long as you take care of your truck no matter what engine it is, it should last longer then the truck itself.

The one dmax my company owned had some pretty significant issues.

The one d max we have issues with has blown up a couple of times now. Just doesn't want to pull a load.

So you are saying the Duramax hasn't really had any issues? At least at your shop?

We only have four of them in our fleet, one of them is our problem child. The other three are pretty good to us. We do not have any of the newest ones....yet.

My dad has a 6.7 that is a piece of shit. Nothing major, just a ton of little issues.

We have had a few issues as well with the 6.7, they have been a far cry from the issues that we've had with anything international puts on the market.

I wrench on all of them.

Along with

7.3L non turbo
7.3L ps. Aka 444e's
DT 466's.
6.0L ps aka vt365's. biggest POS EVER!
Almost every D max. The duramax hasn't been to bad for us.

Where at?

That is what I hear about the 6.7. That there really isn't any major issues just a bunch of little ones to keep your truck in the shop. Hell that would piss me off more then anything.

12v 5.9, 24v 5.9, 5.9 CR or the 6.7 cummins...ill take the reliability of a cummins OVER anything else in the light/medium duty class.

Ask me how I know.

I'm a member on two different powerstroke forums and I have heard nothing but great things about the ford powerstroke. And my father-n-law has 9 new duramax's for his work and he loves them all. He didn't get the new ford cause it's a new motor and didn't want to have the risk of having 9 trucks to have problems but he said he will probably switch over.

The ford engine makes 400 hp and 800 tq
The chevy engine makes 397 hp and 765 tq I believe
And both get about 20 mpg on the highway bone stock I have read.

Most of the cummins on here prefer the 5.9 over the new 6.7. But the new duramax and the new powerstrokes are a beast over the new cummins.

Are they? I heard the Duramax was, but didnt know the Powerstroke was. As far as reliability how do they measure up?
