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

They are just fine if you like sitting in the lounge at the dealership waiting on them to fix yet another emissions malfunction.

 

I've driven DEF trucks since 2012 with zero emmisions problems, and only 1 or 2 parked regens, and automatics since 2015 with zero transmission problems including last 2 years pulling a tanker and getting slammed from the surge until I learned how to stop that. "New trucks are trash" is just what "Y2K is going to kill us all" became. Some people just MUST have something to panic about.

 

They’re not as reliable as the old iron trucks. They still can last 400k-500k miles before major work has to be done. The big issues you get is emissions systems. Many times it’s because drivers idle the trucks too much. Those def systems are meant to be running on highway rpms as much as possible. The filters start to get clogged up when idling too long so the system starts doing automatic regens to clean them up. If you ever notice the trucks with apus get less issues with the emissions systems.

The automatics don’t fail as much as the first generation ones. Of course I’ve only drove with the Eaton c###-amatics they shift bad but they do last. I’ve heard the new Kenworths have an actual automatic instead of a automated manual not sure if the clutch slips like in cars if they do I’d imagine those new automatics are going to be bad.

 

I drove 2 brand new trucks when I worked in the city. I dreaded going to work when I started because I had a standard. The day I got my automatic I was in heaven, no more sore leg leg from feather the clutch through traffic all day.

Now that I am in the oilfield you NEED a standard for most of the muddy icy hills we encounter. Most guys with autos just slip out 1/2 way up the hill.

Personally though, if I’m running a highway truck I would want a auto for the ease and extra MPG your going to be getting.....but I run the field for now so standard is in my books for awhile.

 

I am going on year 2 with a Used 2014 Cascadia . I have had 2 emissions issues Def Pump and they Updated the EGR Valve to a new more reliable one . Both one day fixes at FL dealership. 2014 and up I hear they reworked the ONEBOX to be more service friendly , I figure by now alot of bugs have been worked out .

 

Its not all regen issues. ITs sensors and all kinds of electronic failures. I own an old pete. The company i run for has all newerish macks. Im not kidding you when i say that at least 2 come back in on a wrecker becuase the trcks go into limp mode or shutdown. I never experience those problems.
