Tell me your horror stories (Diesel)

[ib516]

Ok, so browsing through the thread about the 2011 Ford diesel left me in shock. Seems like there were many issues with the early builds of that engine. I know the Cummins and Duramax of that generation had their own issues (mostly emissions related?).

How are the newest gen Ford 6.7L diesels holding up (2015+)?
Are their similar stories for the Cummins and Duramax in the latest gen (2014+)? I know the Cummins has been 370hp/800tq for a while (in the 2500), have they worked out the kinks in that one? Are failures common? I only know one guy with a 2014 Ram 6.7L Cummins SRW 3500. He has had plenty of recalls and was losing coolant a while back, but I think that was the famous water pump issue. He has had no serious issues. His is a 370hp/800tq version with a 68RFE auto. But that's a sample of 1 which is pretty meaningless.

I went with a 6.4L Hemi last time I was shopping as it suited my needs better and frankly, I was scared away from diesels (all of them). At that time, my research told me they weren't worth the gamble. What I mean by that is their superior towing performance wasn't worth it to me when they could cost me tens of thousands to repair if they failed, and they were all (my opinion) having reliability issues in the 2011 to 2013 time period. I thought they were mostly pesky ones to do with emissions, but I'm just not into check engine lights on new trucks.

Are the diesels getting better? Should I put them back on my shopping list for my next new truck?

I'll likely be towing under 10k GVW, and it'll likely be a TT around 30'. I do want to log some miles though, and that will include some long distance touring (cross Country type).

^Literally the next post after 2 posts saying the OP doesn’t give a chit about anyone’s experience with their old, in the past, not applicable to the conversation, Diesel....
Classic!

I had a 6.5 Chevy diesel and it was great until we reached 60,000 miles and it started acting up. No one could get a handle on this POS and it really irked me. The truck was bought new and the fluids and filters were changed on a regular basis. The truck took forever to start and after many (3) starters changed, injectors etc. this truck just went into lemon mode. The final straw happened when wife and I were going to visit her parents and the truck broke down in Mobile Alabama during 5:00 rush hour. We were towed to the impound lot next to the FedEx terminal near Mobile Bay and the owner let us keep the truck there until we could figure something out which ended up us buying a Ford F250 7.3 PSD and towing the Chevy back home to Texas. Nightmare for sure and the real kicker is I worked at a GM plant. This is our story

It's funny that you have to state that AGIAN... Some want to hang onto the past...

From what I have heard, and owners I spoke to, ANY of the big 3 2015 and up trucks are awesome towing machines... The rest is personal preference .

Purr diesel purr!

Bingo. My 2002 Ford is going up in value.

No horror stories with the engine or transmission itself. The only time I was left on the side of the road was when my center (steady)bearing went. FIL has same year of truck only dually and his went around the same time, roughly same KM. Both trucks covered by warranty. Must have been a faulty design as the replacement bearings looked very different than the original ones.
Other than that, the diesel has been flawless. I use mine for both towing and daily driving. No issues

For under 10k a gasser would do and you'd probably come out further ahead financially with a gasoline engine. I'd buy a diesel.

No issues with my 2015 Ford. It pulls like a dream and still puts a smile on my face every time. Diesels may cost more up front but the pay off comes later when you resell it. I'd buy a Ford again in a heartbeat. Good luck with your decision.

I love this forum sometimes. The OP's main question was about the 2015+ 6.7.

All the horror stories we have seen so far are for the 6.0, or the 2007-2011 (First gen DPF/SCR) systems.

The current 6.7 has 0% parts commonality with the 6.0. The systems that caused issues with the original 6.7 generation, have all been addressed, and updated.

The biggest issue I have seen getting attention from the current 6.7 (2017+), is that they absolutely do NOT tolerate water in the fuel. Check the separator often.

2005 Ford, F350 6.0 Diesel, Thats my story, not good.

X2 only issue with mine was the def tank was replaced under warranty.

[larry_barnhart]

Our 05 duramax runs better than new at 101400 miles.

I didn't think I would ever feel that could be true.

The dealership I bought my latest truck from sells Ram and Ford, and has the lowest prices for several states around. People actually fly in to buy their truck here.

Hey 3TV, whats the name of that dealership? I might have to book a flight!....lol

[TwoManyToyz]

I don't own a diesel, my F-150 has a 5.4 gasser in it. She is still really strong. My buddy has a new Dodge diesel and loves it. My Next truck will probably be a F-450, it doesn't come in anything except diesel.

I'll go out on a limb and say that by now the big 3 has their act together with trucks. Ford, Chevy, Dodge. You buy what you like. truth be told your going to get 1 or 2 bad ones out of every ten anyway from every brand. Just make sure you find the problems before the warranty runs out..

Diesel horror story? Diesel running 60-70 cents more per gallon than gasoline.

It would still have the same cost per mile as a gas engine at 60-70 cents more.

Cost per mile formula

(1 mile / miles per gallon) x fuel cost per gallon = cost per mile

Example:
Ram 6.4 Hemi
(1 mile/12 mpg) x $2.50 per gallon= $.21 cost per mile

Ram 6.7L Cummins
(1 mile/15.5 mpg) x $3.20 per gallon = $.21 cost per mile

DEF adds $.001 per mile

Yeah, but now it is not paying anything toward that $8,000 diesel engine investment.

That is what resale/trade-in does. Unless you live in some weird dimension where diesel has equal resale/trade-in value as a gasser and not the usual $6-7k higher. Just as a V8 Mustang or V8 F150 commands a higher value over a V6 Mustang or N/A V6 F150 due to its greater performance and capabilities, so does an HD diesel over its gasser equivalent. They are NOT equal in value because they are NOT equal in performance.
