6.2L or Duramax reliability

[Baja_Bob]

So the 6.2L doesn't use the 10 speed transmission?

I hope the diesel is still available when I get my next Yukon, even though the 5.3L suits me just fine.

All 2021+ full size GM SUV’s use the 10L80 transmission…

What is the longest miles you have driven in a single DEF vehicle?

300k sometimes more. Company would trade them in around that time. At that point tho we would always have a new transmission. So if your worries about something that would be something to worry about. It's not a conspiracy. Working for GM we didn't see that many failures either. But a whole industry has built itself on the notion that it's some overly complex system that needs to be torn out. Of course they charge you money for that and many have paid for the privilege in the way of huge fines from the EPA. Sure the system can have failures but it's simple and quick to get them back on the road.

I think the most inconvenient aspect is running out of def or system thinking it's out or low and reducing performance as a result. The rest is just over blown sensationalism.

What's the name of a car that has driven 300,000 miles in your possession with the Def system without breaking down

I have about 80-90 units in my fleet that have that many miles, or more, with a DPF/DEF system. 1 has 1,056,573 miles on it now, and it still has the factory DPF system. Although the dozer has been replaced twice. These are semi trucks, so I dont know if that counts.

I made the comment in another thread, diesels are meant to be driven. Yes you can drive them short distances repeatedly, but it comes at a cost because the DPF cant get to temperature so that the SCR system can work properly. It will get clogged. It will need to be cleaned/replaced.

Theres a reason that in Europe, they done have these systems.. They dont work. They cause more damage. They are worse for the environment.

Wait, I don't mean commercial equipment. I'm talking about cars .. The fact that the Def system works perfectly on trucks, I know, the problems began when this system reached passenger cars

LML and L5P some trucks some cab chassis configurations. Some had more then 300k

Gotta move the goal posts lol

Irregardless of the above... If you can drive more than 20 miles at almost each and everytime you turn the key, you will be fine.

If you cant.... Well, they do make other vehicles/engines.

This is the reason Ford and Mopar quit making their 1/2 ton diesel. People were not driving them to the point of SCR Efficiency.

Here is the answer. This system is great for commercial vehicles, but not for personal cars. Where the road is most often home-school-work-home. Or house-supermarket-house
