2026 International LT: Should be bringing it home tomorrow.


At home getting the engine light checked out now. Third time for it to come on, plus trailer developed a small leak, so dropped them both off during my time at home.

Did your light finally become constant? Mine has been on the last week or so. Usually it clears itself after a couple trips.

No, it comes on for a couple days, goes off for a day or two, and then repeats the cycle. Being a DFP code, got it put into the shop to avoid it becoming a derate issue out on the road under a load.

Now, the dealership is baffled and don't know what to do about it. Waiting on Navistar to advise them.

I hope this is it for the new truck bugs. The computer actually thinks the DPF is missing from the truck. Very strange code.

That's odd. If I was wilding like you I'd want on it ASAP for the same reason.

turns out, it is a known issue and will be a programming fix. They haven't come up with the reprogram to fix it yet though. Safe to drive, no derate concerns, or at least that is what they told me.
 
well since they haven't the fix yet what else could they tell you, keep pouring the fertilizer into it and hope it doesn't leave you stuck in the desert somewhere
Its probably just a couple missing lines of code in the ECM.

But also retarded as hell for it to be a thing in the first place.

Or, hopefully, it's just a bad sensor that's not detecting what it's supposed to be detecting.

I'm a little annoyed with emissions trucks, but I also don't miss choking on sooty air. My pickup has zero emissions and that black smoke makes me cough sometimes.
 
Agreed. It's an international though. Remember the Maxxforce fiasco.

Yes I'm aware of the irony that my pickup has an international engine. It's from a better era. 😂
Yep. That scares lots of people away. There's no way I would have jumped into this powertrain year one.

I need to enter all of my fuel purchases to get an actual average, but I am still amazed at how well this thing is doing. I'm adjusting to the lower power compared to my last two trucks, but the fuel economy is a perfect trade off.

I was supposed to deliver a load yesterday in Bentonville, AR. The load got rejected because the warehouse was full. They finally got a new delivery location set up for Springfield, MO. I had nothing important to do, so I left out this morning with plenty of time and ran the truck 55mph, just to see how it could do with a heavy load and the rolling hills of I49 and I44. Made it to Springfield at 12.3 mpg.

No intention of driving that slow on a regular basis, but it was a good day to see what the fuel economy result would be.
