I continued searching for answers to this little mystery and found this thread on the Cummins forum:
https://www.cumminsforum.com/threads/hour-meter-reset-itself.2470949/

This appears to be a fairly common occurrence. The Drive hours reset to 0, but the idle hours don't change.
I'll ask the dealer to check for the correct numbers (from the PCM or wherever this data resides) if I ever take it in.

Thanks for all the replies.


I read some on the thread you posted on the Cummins diesel evic mysteriously resetting the drive hours.

It seems that 2017 year models is the most having this issue?

I don't put much stock with the accuracy of the evic monitoring idle hours/run time and ain't gonna worry about it 'cause I ain't trading/selling my HEMI for it to matter. jm2$¢.

Just curious. Is this happening on the base-style EVIC; the 7-inch multi-colored EVIC, or both?

I know this thread is a bit old, but I referenced it before I bought my rig. I bought a 2019DT , 87k ( so you can see why I was interested in engine hours ) It did help me make my decision. Mine has 87k miles. 2200 engine hours 90 idle hours. Yes somewhere just below 5%. Yep, I said she was a keeper when I saw that. The other rig, i was looking at, had only 41k miles. But it had 550 idle hours and 1000 engine hours or something. I was about to pull the trigger on the 41k rig.. but this flipped me 100% It tells you much more than just miles. So when I saw that on the lower mileage rig, I immediately asked the the salesman for the carfax.. and when he walked up with he said it was fleet lease. So, not that is not a good idea to check carfax , as it can tell you a lot. But it tells you how important and useful this engine hour stuff is. So , I ask you now , you are looking at two trucks , one with 41k and the other 87k. Which do you buy? but the 41k has 550 idle hours and is fleet. the other is 87k 90 idle hours, one owner. local owner. If I could tell you how many vehicles I saw imported from all over the country , obviously auction rigs. I even was looking at one, when my wife noted a ghosting of a sticker from auto dealer in Canada. I dont need a cold weather car, when I live in the south. 25 below starts are extra wear on the engine.

So , my point is we have to think about use of vehicle when buying used not just mileage.. I hope someone can benefit from my buying experience. I am hoping I have good 3-4 year old rig that was gently used for a very consistent 2200 miles each month that seems to involve not a whole lot of stop and go. Truck should be good for another 100k easily.

ALso, it seems very apparent that, some of the EVIC ( I think base ones ) seem to reset at 1000. From what I am seeing in the threads, and the trucks I shopped, the numbers make sense if they are off by 1000. Some may be off by 2000. It still seems you can deduce useful meaningful information from these.

My 2015 SLT QC 2WD 5.7L 8 SPD 139,155 miles had idle hours 342 / 4050 drive hours in the evic when I changed oil yesterday.

Does anyone know if idle hours are separate from drive hours or part of them?

My idle percentage would be slightly less tha 8.5% if included, and slightly less than 7.8% excluded.

Either way, I will take it.

Apparently the EVIC has issues, according to other member's data earlier in this thread, so I wouldn't put too much stock in it either way. You'd think this would be one of the simpler data collections to report for the software engineers. Guess not.

At an average of 275 mph on your clock, were you running Premium or the new 15% ethanol? Just checking.
You should be on Street Outlaws at that speed. :)

----------------------------
Current mileage is 41,600.

Those numbers just don't make any sense.
To have travelled 41,600 miles in 151 hours of driving, my average speed would have been 275.5 MPH. o_O:hmm:

I would guess that the correct DRIVE number should be between 1200 and 1500 hours.
What could cause the Drive number to be so ridiculously low?

In searching for similar issues, I saw a comment about random DRIVE hour resets to "0".
Is there any way to verify if that has happened and/or what the correct DRIVE hours are?
Thanks
Joe

Disregard. I see someone answered the question a few posts up and I missed it.

Assuming we really idle 225 hours versus there being a glitch in evic display that chrysler/fiat/stellantis says meh we already got your money F.O. we ain't gonna fix it sounds kinda condescending.
