Current GM / Chevy Reliability

Your rational is flawed to say the least. Cummins makes a good engine and they are highly respected, the Duramax and 6.7 Powerstroke are also highly respected. They don't build their motors to be put in non GM or Ford vehicles. You don't know the motivation for that and I don't either, although I can make a few guesses. Maybe they don't want to compete against themselves in selling vehicles. Maybe neither GM or Ford want to be in the business of selling their engines on the open market. Perhaps engine buyers in the market for a medium duty powerplant don't want to help out a competitor by buying their engines? There are a lot of potential reasons, but Ford still controls the MD market in sales (450 and 550), and does it with their own engines. If I were buying a 650 or 750 I would probably pick a Cummins if for no other reason that there are a lot more places to get a Cummins worked on then there Ford dealerships who work on a 650 or 750. You say not "MD enough"? By what standard is that measured? Is there an SAE rating out there somewhere on MD engines showing Cummins makes the cut and the other two don't? Do tell. Cummins is a fine company. I wish them well but I don't want one in a pickup, that is my choice. Your continued self-justification of your purchase goes way overboard, you take fanboy to the next level.

Just because a manufacturer takes the Lego philosophy of production does not negate the validity manufacturing your own product. I don't understand your rational. How many Cummins make trucks do you see? Is the supercharged hemi not a performance engine because you can only get it in a Chrysler product?

Cummins is in the business to make engines. They are the highly respected Company. If the other two were MD enough they would be selling them to other builders.

Until a couple years ago F650-750 had Cummins Diesels and Allison trans. Trans were NOT the same as used in HD GM’s.

I would be curious what their sales were/are between the two power trains.

I think anyone being honest would take the Cummins/Allison combo given the choice in a 650-750.

2016 2500 Duramax bought new.

42K on it now.

So far:
The power steering box failed (warranty repair in the first year)

The cab developed a leak behind the back seat (found at 300 miles over 36,000 bumper-bumper warranty, so not covered - repaired myself - not fun)

DEF tank heater failed about two months ago (just repaired today due to parts on back order - covered by warranty)

That's been it. Although some of it's been a pain to deal with, it's a short list compared to some of the stories I've read.

Starting in 2010 after Michigan economy tanked my dad and I went to pulling campers out of factories in Indiana. We have over 2.3 million miles on five GM diesel trucks.



Pictured is a white 2009 with 630 thousand miles. Had the motor replaced around 250k do to bad injector which my dad swears was bad from factory.

The Grey 2010, which was sold at 853k to the transport company I work for down in Indiana. Original motor, dpf filter was replaced around 470k and then whole emmisson delete after I sold it. The guy who drives it now used to drive Dodge. Loves this truck.

Next is the White 2013 I'm currently driving. 643k has had the whole emmisson system replaced once now. And at 595k the fuel injection pump was replaced. This newer truck runs cooler, has more power and better brakes compared to the older ones.

The Red one is a back up truck I bought new in 2013. Cab and chassis model dually has a 9 foot flatbed. 82k miles. Do to the extended length of the bed and the 40 gallon behind rear axle tank the truck does not handle bumper pull trailers as well as the other trucks.

Not pictured is my dad's current truck 2017. Up to 187k miles. Truck needs it's first front end alignment. This newer engine has even more power compared to the 2013s. Downside the hood is higher, lights are not as bright. The truck runs very quite compared to the older diesels, can't really even tell when the truck is working.

Considering getting a new truck. 75% general duties (including hauling ATV's, boats, and other toys): 25% dedicated hauling of either a flatbed or a "camping rig" (not strictly an RV).

The new truck will be a 350/3500 SRW and a diesel.

My question is what the current overall reliability of current GM offerings is?

The truck being replaced is a 11-year old (2009 MY) Chevy 2500 and has been a good truck until the past 18 months when it's crapping out in every conceivable way. Always had a slight preference for GM, but this has taken the shine off GM a bit.

Should I start evaluating 2 brands (blue oval and Ram) or 3 (throwing in the GM)? I'm hoping that this will be my last truck.....

The "reliability" of all the Big 3 offerings is about the same. They all have issues. No one brand stands out as having stellar reliability over the other so buy what you like. If you like Chevy/GM, buy that. They make a great truck. So does Ford. I like them all but went with the Ram CTD because they're about 10 Grand less (in my neck of the woods) then Ford and GM.

Owning Chevys, I've gotten real good at repairing clusters and ABS lights but all engines were bulletproof, I've owned 4.

We all drive trucks in the mountainous area I live and talk trucks and the consensus is the big 3 " ford-Chevy-Dodge " build better trucks today.
Better fuel economy, better features and MUCH better transmissions where 8 speed autos are common now.

I'm buying a new truck after the new year and leaning toward Dodge 2500 Tradesman with 6.4 Hemi.

Yes, Toyota's are mechanically reliable but not for the whooping I put on a truck.
I can't own a 1500 series truck from any manufacturer.

Big “C” plus AISIN both true a Medium Duty.

Look on the Highways, vast majority of independently owned RV Haulers and HotShotters drive RAM Trucks.

But they now have hydraulic lifters and a CP4.2 pump so they can't be medium duty.

They certainly are still putting them into MD trucks.

That's the diesel I'd pick in 2019+ models, and that's coming from a very satisfied Cummins owner. I'm surprised your 2009 is taking a dump on you so soon, though.

That's a very strange position... If my Powerstroke left me and my family stranded I wouldn't be a very satisfied owner.

I don't think it's strange. Cummins or Ram got a bunch of flawed water pumps and I got unlucky. I wasn't happy about it but I ultimately got reimbursed for the repairs that I had done at a private shop, and that second water pump was also replaced for free under the subsequent recall. Other than that I haven't had any significant issues with the truck and it hasn't given me any reason to be concerned about any major issues on the horizon, and it drives, performs and looks great. I still think of the 2015 vintage diesels the Cummins is the best of the three options by a significant margin.
