Kenworth SCR Blues

First, a little background. I picked this truck up on Monday (20th of this month) from a Kenworth Dealership/shop in Menomonie, WI. It only has 22,000 miles on it (2015) and looks pretty clean. I drive off to a Swift terminal to get my permit book looked over and to be issued any stuff a new driver like me would need. I then accept my first load. It is on the other side of the state, and my appointment is first thing in the morning. So I get to about 25 miles away and shut down for the night. I don't idle since in cooler weather you can just bundle up and use the non-engine powered heater. The next morning I wake up, start the engine, lo and behold there is an SCR system fault message. I call my Driver Leader and she says to go ahead to my pick-up location and do a breakdown macro when I arrive. I do so. Upon arrival it goes to a full de-power limp home mode. So basically I limp to a shop (Freightliner), get a re-power, limp to another close by shop (Kenworth), get "fixed", and pick it up Friday morning.

I leave and pick up another load. Deliver said load the following morning. Shut down. Wake up. Pick up next load, get 300 miles down the road, fuel up get DEF, shut down. Wake up, start the truck...and what do I see? Correct, the SCR message again. So I immediately call the Swift On Road people and tell them my situation and how this just happened to me a few days ago. I call my terminal to get a re-power.

So now I'm waiting for the re-power and then I can get my tow.

Here's my question. This is obviously a repeat problem (I'd be willing to bet my meager paycheck that this is the reason it was in the shop I picked it up from) with a known issue (you can google it, been around a few years)...does anyone know if there is something I can do to keep this from happening. Being in the shop every week means I won't be making money.

Leave it running 24/7?

I'd love to, but I'm sure Swift would take issue with me doing that.

Is it an ISX15 engine?

Yes, it is. Cummins.

Great. I just put mine in the shop again when I got back from Chicago today. In the month and a half or so I've had this truck, I have driven it about two weeks. Hopefully this recall will take care of it. I just remember it's a 2010ISX... I think it's a 15, but not 100% positive. Was manufactured in 2011.

Yeah, we found that article last week. I think there is going to be an interesting conversation tomorrow at the KW dealer.

Welp, after turning the KW in every-other-day to the shop (they said there's no recall on it), they're sending it to the dealership. My fleet manager let me pick out a Volvo. I'll miss the KW, I was kind of getting used to it... but I get around better in the Volvo.

Good luck! Sean's truck was actually fixed by a shop/dealership that looked at more than the symptoms. Turns out there was a bad fuse block under the hood. It "never goes bad" so they had to overnight one from Atlanta. Seems to be running like a champ right now.
