13 Hours! and 28 Miles on a Brand new 2019?

When I got in my truck for the first time picking it up at the dealer for a test drive / shake down run I noticed on the DIC that it had 13 HOURS and 28 miles on the truck. When I asked my salesman he said that was average for all delivered Duramax trucks, Really?

Why do they leave it idle so long, supposedly that's not good on the new Clean Diesel motors? Ironically at 50 miles on my truck (just after I got it home) it kicked into a REGEN cycle. Obviously due to the idle time before delivery.

Now after 6 months and 4500 miles it's driven only on trips no shorter than 30 miles at about 60mph and it's Never had another regen cycle.

Anyone know WHY they let these new trucks idle for so long before

Thanks,
Epicenter

Haha no, if it really hasnt regened in 4500 miles, there is/already is going to be a problem, I highly doubt it hasnt regened for that long. Do you have some sort of way to track it like an edge insight or something? Also I would not say 13 hours of idling is normal for brand new trucks, I would honestly be concerned about how that engine is doing internally, that much idling on a brand new diesel engine may mean that the rings dont seat correctly, and your truck burns a significant amount of oil its whole life. The only thing I can think of is that those hours might have come from dyno testing at the factory??? 13 hours though is a significant amount for a truck that has 28 miles on it. I would not have purchased that truck, hopefully it is ok, just watch the oil level, I would be most concerned that it may be burning oil. I would also change the oil ASAP, because if it really idled for that long as a new engine, I would be willing to bet that the oil is very diluted with fuel.

While I'm a big believer of breaking motors in hard or under a load, yours will be fine. I wouldn't worry at all. Also it has definitely done multiple regens in 4500 miles

Are you saying it gave a 'keep driving' message at 50 miles?


Normal regens will not give any message -- and as others posted, it will have done a bunch of them by 4500 miles.

Yes it did I don't recall that it said "50 miles" but it said "Regen...Keep Driving" seems like the message dropped after about 30 highway miles, I was Very surprised. My wife was with me and said, "These Diesels aren't going to ask you to do THIS every 50 miles are they." I told her I believed it was because of the apparently long time it spent between my dealership and the Factory Idling (crazy 13 Hrs!). Interesting that' I've never seen another one since and I've got 4619 miles on the truck now but it spends very little time idling and very little time with any city driving/stoplight to stoplight.

Thanks for the reply!

Thanks,

Both yes, It regened at 50 Miles and I now have 4619 on the truck and it's not had another one. I do mostly highway driving, very little stoplight to stoplight.

Thanks Yes I thought it was excessive as well. Seems to be running great, I appreciate the input. I'll be taking it in at 5k to get the oil changed and tires rotated. I don't know if this matters but I was told when I ordered it back in May that it was the 4 "customer ordered 2019 3500HD Crew Cab for the new model year so maybe they did additional testing or something? It was built on 6/25/19

Thanks,

So It Doesnt pop a message when it's doing a Regen? I guess I thought it would, you're probably right then. Was that message more of an "exception than the rule"?

Thanks for the reply
