These unreliable new diesel engines!

[ShinerBock]

Apparently my 2014 Ram Cummins with almost 100k miles on it must be a unicorn in the fact that it hasn't broke down on me yet because many people here(mostly non late model diesel owners) think that new 2010+ emission diesel trucks are just unreliable and will leave you in the shop more than on the road. Now I do agree that there were many issues when the emissions systems first came out as with anything new and some diesels with a CP4 pump did have issues.


So to all you 2010+ diesel truck owners, please post your year, engine, mileage, and how much time & and money spent on repairs (not maintenance) to the engine or emissions system along with what was done. I will start it off.


2014 Cummins
96k miles
$0 repairs
0 time on warrantable engine or emission system repairs
1 engine recall performed - replaced waterpump(which was still working fine)

The dog not puking is always a great thing! :B

2017 RAM 3500 with only 8000 miles. No problems. Amazing machine. Love it. Went up a ten percent grade at 70 mph pulling 9000 lb and barely got over 2200 rpm.

I love the "no drama" way a modern turbo diesel pulls up a long grade. The only real sign my lml Duramax gives me that it was working hard is hearing the fan clutch fully engaged when I get to the top. Exhaust braking down the other side is nice too.

I just got back from a 2000 mile trip to Tofino with my 2012. Got 12.4 mpg average while towing and not a single issue, whole family was comfortable with the A/C cranked and the XM blaring. Dog didn't puke once either!

I see most of you have under 100k mile on them with no issues, well I would hope so. Wait until you have almost 300k and then come back and tell how well they held up. 250k on my 7.3 that has been chipped since 30k and 1 water pump, 2 altanators , 1 AC compressor, 1 belt, and other things not under the hood related, all of the turbo boots have been replaced, seams I keep blowing one of the off. Both front hubs, brake pads every 90k and tires every 30 to 40k, new seat covers, new head liner

Of course, it's not quite as good as my Cummins! 😉

The injection pump is the potential issue.

My 2015 Ram 2500 CTD has had the catalytic chamber in the exhaust and the water pump replaced, both under warranty. It's also had a couple of recall software updates dealing with the passenger airbag. Everything has been covered by warranty and cost me nothing but some time, although they were in conjunction with an oil change so it didn't take much extra time.

I now have over 67k on the truck and love it. I've not had any problems whatsoever. Well, there's that one time when it quit while running 70 mph down the freeway but my wife had driven it previously and I forgot to put the seat back and my knee hit the key fob and turned it off. 🙂

Had 180,000 on my first Dmax now have 72,000 on my 2015. Has DEF problems mostly and a exhaust gasket for DEF also. Love my truck and use it for travel only. Got a 2014 for fun and city stuff. Life is good just don't weaken.

Back in shop because ambient temp shows a different temp than outside, example: it showed 32 degrees this morning when it was 50. HVAC does not work properly, can never get it to a comfortable temp, always too hot or too cold. Been in shop and they tell me all is good and while driving home and it’s 80 outside, ambient temp shows 30.
I have owned Chevys since I was 16 and I’m 59 now, this is the last one after the customer service I have received.
Never should have sold the rig in my signature, a 2016 LBZ. That was a great truck.

Find a new dealer/shop.

I don't have that luxury, I live 45 minutes from closest dealer. Having to leave the truck for several days at a time and coordinate rides home and back to dealer is not easy.
I don't live in an urban jungle with multiple dealerships willing to work on my truck for warranty.
Chevy doesn't pay them for diagnostic time, just repair time. Bad system in my opinion. Im sure all the major manufacturers have the same system but that doesn't make it right. Not a lot of incentive for the shop to spend a lot of time diagnosing, is there?

Properly maintained it will get you much more than that!

[Grit_dog]

Litch, that’s always frustrating.
If it makes you feel better, the other mfgs aren’t immune to random issues and incompetent service departments.
I’ve owned or driven (exclusively, work trucks assigned to me) around 30-40 new or newish pickups of all 3 brands since the mid 90s. Know what? Most of them have been basically perfect and 1 Dodge, 2 Fords and 0 GMs have been problem vehicles.
Luck o the draw man. The new L5P Dmaxes aren’t any more problem prone than the others.

I had that problem with a car (Grand Prix) once it just needed a new outside temp sensor, also when it would show the false cold temp the AC would not work right.

There was some logic to cut the AC out at a certain low outside temp.
