What is the REAL problem w/the 2016 Titan XD Diesel

I've had my Titan XD for nearly a year now. On a number of other forums (boating, shooting, etc) I keep reading how we'll never get 300k miles out of these trucks due to DPF, etc. "Just a bad decision to buy this truck".

I went and did as much reading as I could to educate myself as to WHY it is that people say this, and I'm not coming up with an answer. I certainly don't consider myself a gearhead, but I am an engineer by trade, so I can logically assess a situation and come up with an answer if I do my research.


So let's begin.


My history with Nissan goes back five vehicles: two Altima, an Armada, a Maxima, and now my Titan. In none of these vehicles did I experience any major problems that weren't self-inflicted (wife drove over a curb in her '98 Maxima in 2010 and did some underside damage. We just traded it in on a 2016 Jeep Cherokee Overland). The Armada performed magnificently everywhere except at the pump. The Altimas were flawless. So Nissan - the platform - was without problems.


Cummins is considered by many to be the Gold Standard of diesel engines. They've been around for nearly one hundred years. With the exception of two 5.9L engines (the "53 Block" and the "Killer Dowel Pin" that occurred between 1988-2002) their engines have been bulletproof (or so I've read). So I believe it's fair to say that they have a history of making reliable Diesel engines. The 5.0L engine was supposedly nine years in the making, and is a completely revolutionary design, making more use of a CGI block, newly designed turbocharger that is more fuel efficient, and better emissions control - which I understand is a bone of contention with many - but the government mandated it so we're stuck.


The last major component is the transmission. For that they used the Aisen A466ND - which is basically the same transmission that the Ram 3500 uses. Supposedly it's overspec'ed for the Titan/Cummins pairing.


So now, with all of that, where are the potential flaws in the design of this truck that would prevent it from reaching 20 years or 300,000 miles?


I'm not interested in comparisons of this to other brand trucks; I bought this truck and it's the only one I want to discuss. Please make compelling cases as the design flaws that will prevent me from getting 20 years/300,000 miles out of this. I should add that I have a lifetime warranty on the powertrain, and the vehicle will follow factory maintenance schedule completely.


Please help me understand why this won't make it. Thanks.

search the defect sub forum for your answer. I know the turbo had some problems.

I have about 25K on mine and it has not been to the dealer yet. It has so far been to Alaska for a shake down cruise 6K miles. No problems other than the tail gate latching system fell apart; repaired in a campground with what I could find and what I had with me. It also did the Dalton highway all the way to Deadhorse. I also camped about 150 miles from the nearest town for 3 days; started right up. It also went to Texas for Christmas 5200 miles trip. It took everything in stride, zero temps, snow 4 inches on road, rain, 75 degree heat in Texas, lead footed wife, 90+mph on a freeway a few times, ice on freeway, 3 days with no shut down, and a 4 hour nap in zero degree weather with the engine running. I have changed the oil and fuel filters at the stated mileage maintenance. I still have to do a transmission filter and oil change still waiting on some dry weather to do it ( it is rainy Seattle).
The tranny is well matched for the engine and is most likely close to medium duty as you can it. The rear diff and rear suspension is definite 3/4 ton with no problems. The front is like a 3/4 ton and they used 5/8 ton springs. The drive-lines are Spicer top shelf there too. Brakes are over sized so that is a plus. The 4x4 system is great works like it should.
The engine I think with proper care and OEM replacement parts it should last 300K. I use a rotella 5-40 T6 oil and amsoil for the rest of the vehicle. The fuel system concerns me a little bit because of the hi-pressure pump for common rail system and fuel pump that is inside the primary filter housing. The high pressure one I do not know how reliable they are; I know that it is Bosch. As long you do not run it out of fuel it should last. Emissions; I think there are some problems going to be there and Egr system will need a clean out once in while; that might be expensive. Really too early to tell if there are head gasket problems and hopefully Cummins did their homework. I am a firm believer about oil analysis that will give some heads up before impeding doom it has helped me in the past. Drive lines need grease zerks and the front suspension also.
The other concern is all of the computers are in truck all talking to each other on CAN-BUS. Hopefully the wire bundles are well tied down and connections are good.
Overall I am impressed with the truck; fit and finish of the interior are like a new Boeing airplane.

Im sure it would go 300k but like all modern diesels it will not do it without a few major expenses along the way, unless you delete all the emissions stuff that wasent on the 5.9 and do proper maintenance

Yes, delete, delete and delete some more! I've never had a vehicle that didn't go at least 200,000 miles and they were gas engines. I have no reason to believe that this diesel won't do that or better....with some maintenance....

To answer your question tho... The issue is titan to all other fullsize truck ratio is so low it will take another 11 years for minor issues to arise and changes to be made and who knows how long for some real aftermarket stuff to be available. Luckily the truck is pretty well perfect in stock form,,,for now,,,for me anyway,,,lol

Yes, the turbo did have problems; it was not lubricated properly at the factory and they did a recall and replace on it. They have since corrected that on the line, so going forward that will no longer be a problem. I'm looking for an inherent design flaw that would require them to "go back to the drawing board or else it won't make 300,000 miles".

With proper maintenance any vehicle will last 300K+ miles. There is no way these trucks will run 300k miles without some problems though. IIRC, the DPF system is designed for 100k miles. So, somewhere around that time, you should have expectations of having to remove/replace these components. Water pumps, fuel pumps, oil pumps, etc... certainly are not rated for 300k miles and will have replacement intervals well short of the 300k mark. Other fuel system components like glow plugs, injectors, etc all have a time line. Bearings, hubs, ball joints too (not to mention alternators, starters, sensors, other electrical components, etc..). Basically, as a whole, the truck will last as long as you want to spend money to fix it.

So, i guess my question to you is : What exactly are you asking? Are you asking if we think the engine specifically (block, pistons, heads, etc..) will last 300k miles? Are you asking if we think the truck will run 300k miles without any major replacement items?

I'm curious about the drivetrain (engine, transmission; anything bathed in oil) myself. Does everyone think they are 300k durable?
