Are the newer trucks really that bad, no longevity anymore?

Uh no.
New trucks are trash is exactly right. DEF problems all day everyday! Companies that have a good size fillet with manufacture approved techs stock all the fed related crap in stock! Go ask your local techs what problems they run in to.

 

Lol. It’s not quite that black and white. Not every small fleet or owner operator runs old trucks and not every small fleet or owner operator that runs a new truck has issues.

 

I don’t think anyone is dumb for running an older pre emission motor. Some of these new ones have bugs right out of the box. It costs money to be down but at least it’s under warranty. Those are few and far between. Emissions motors had a bad reputation and made even worse by the whole Maxxforce thing. If you look at 2015 and beyond and especially 2017 and beyond, these things are much improved over the older ones and require little maintenance, also get outstanding MPG. I’m running the new A26 and have been very impressed. If you’re running a pre emission motor or seeking one out based solely on the assumption that these new ones are broke down all the time, I don’t think you’re dumb, just misinformed as to how much advancement has been made.

 

Basically with the new engines aviod the following

Paccar MX13 = trash (and it's gutless too, no power)
Cummins ISX = Junk
Navistar = Joke

 

I’m running the new Navistar A26 and it’s been great. It’s a completely different motor than the N13 or MF13.

 

How new are these motors exactly?
You know anybody who's got about 4 or 500k on one yet, not tthat that's anywhere close to high miles or anything, but do they make it that far even without serious issues.

 

Seeing as how it hasn’t been out long I doubt there are many in that mileage range.

 

From what I've been able to find they've only been around for a couple years, not really enough time for anybody to truly find the bugs in my opinion. Not sure what sort of real world testing they do, hopefully more than they must've done for the maxxfart.

 

I think the new ones will do just fine. The 2010-13 model SCR motors had problems, and I think you really didn’t start seeing good results until 2015. The EPA2010 Cummins I had was just over 600k miles before anything went wrong. One of the lobes on the cam failed and had to replace cam and most of the valve train for almost 7k. The guy that bought it is running it now and hasn’t had any issues out of it. I see him every once in awhile because he lives in the same area as I do. I took good care of it and so did the fleet before me and didn’t have hardly any idle hours on it.
The other Cummins truck was a 2013 and it had loads of problems. EGR system, turbo, and horrible fuel mileage. It’s all about maintenance. That one was a large fleet truck with no APU and high idle. Bare minimum preventative maintenance.
Do the intervals the manufacturer publishes, run oil samples, and don’t idle it and they’ll last a long time.

 

When they had the big wigs in court they openly admitted that they knew the Maxxforce had a high failure rate but sold it anyway. They manipulated their data and knowingly defrauded customers. All those guys are gone now. Engineering and management involved in that scheme have been replaced with new, motivated people.
I put an Amsoil Oil Bypass system on it and after the first 250 miles the oil is clear and only slightly dark. I can read the hashes and letters on the dipstick. Usually it’s opaque and black, like any other motor. I’m excited for the first 20k mile sample.
