Got to be honest- the amount of crank failures, engine fires, blued bearings, (insert your favorite flavor of failure here) has got me worried as an owner.

I guess what I’m getting at is- do I delete and bulletproof the truck or do I trade now while I can. Really has me on the fence with all the recent threads popping up on here. Granted, I know this a small sample size of truck owners on here- I also realize that some folks create an account on here solely for an issue they have. But, I’m still worried.

Just looking for everyone’s thoughts on all the ‘bad news’ lately!

In case anyone cares: 2017 SL trim diesel w/ 22k miles and is bone stock. Also, I swindled my dealer into a free maint package- so every bit of work has been done by them, on time, for free.

Nice swindle!
Im not worried. I would be if realbored said these trucks are catastrophic failing at 10% or higher rate but i bet its closer to 2%. I have faith in Cummins. I expect my truck to live a long time. With that said i dont use high tunes and i run amsoil and bypass filtration because i want the best chance possible to not be a statistic

 

Actually I bet it’s closer to 0.2% that have had serious engine failures. It just is human nature to be concerned when we hear about this but the Dodge Eco Diesel has had many many more engine failures. Both GM and Ford had plenty of fuel system failures, there isn’t a perfect setup out there that doesn’t have its small sample of issues. I wouldn’t worry about it as it still is very unlikely to have a major failure.

 

I personally wouldn’t get too upset. I think some of these issues are from this truck being new. Every single vehicle in production has its own hiccups and gremlins. I don’t care how smart engineers think they are it takes a couple years to work bugs out on any vehicle. I personally wouldn’t have bought my truck if it was the first year of production. It’s just my preference to give it a few years and let them work out the bugs. Even then there’s no guarantee mine won’t have issues. It’s a good vehicle overall. Bad news always travels faster and further. I wouldn’t sweat it. Also I’m deleted and I don’t think it bulletproofs anything. It does however make it twice as enjoyable to drive/own.

 

The 6.7 cummins has always been notorious for blowing headgaskets.

The the late 5.9 known for valve issues.

Early 5.9l/24v known for pump failures.

Then there was a phase of bad block castings known as the 53 block from Cummins that was prone to cracking.

There's always gonna be something..


That's why everything needs to be modified! Lol

The 53 series blocks were only prone to cracking when used in a 5.9 common rail. I have seen 53 series blocks out of heavy equipment, medium duty trucks with thousands of hours of abuse with no cracks. As well as 5.9 12 valve performance trucks that haven't had issues. The common rail motors created too much pressure in the water jacket which resulted in the cracks.

 

No, I totally get common issues among same make/model. This one is just a little more catastrophic than I like LOL.

I was a first MY 6.0 Powerstroke owner, so I know cstastrophic failure all too well- it’s wildly inconvenient to deal with, probably more so under warranty.

I’m not having buyers remorse or anything. I just enjoy this truck so much, and I want it to last.

Probably will delete it soonish, just to try and clean it up a little more. I have been doing lots of research on the oil bypass kit, as well as the FASS kit. We will see, I suppose.

I think its probably a little overblown about engine failures. This engine has been around a while before the XD ever came out so I think Cummins has it right. I think some of the problems is Nissan's programs interfacing with Cummins. Maybe a bad run of cranks account for some of the problems? I deleted at 39,000 miles and am now at 57,000. If you are not deleted I think you should run an oil bypass filter. Before I deleted my oil would be jet black after just a few hundred miles. Now it stays a nice clean amber color between changes. That EGR is putting a lot of soot into your oil. That certainly is not good for your engine.

 

Precisely why I want to delete, right there.

 

Isn't this 5.0 the first from Cummins on this line of size? Both Cummins and Nissan said so when they first introduced this engine.

 

The engine was originally developed for Nissan AND Dodge as a joint venture. Dodge (or Ram rather) bowed out when the economy tanked in 2008ish. Cummins originally developed the ISV motor (5.0) as a commercial motor that could go in RVs, medium duty trucks, etc., and the 5.0 Nissan version. They are nearly identical, although the ISV does not have the turbo configuration found on this engine and is rated slightly lower power wise. You can in fact buy an ISV straight from the factory if you want to as a commercial engine.

 

I am only aware of three crank failure cases at all, let alone a significant number of them. The XD is not without its squawks, but I would hardly call the crankshaft a common point of failure. I thought all three of those trucks were tuned anyway?

 

You’re definitely in the dark, then- hell, one guy has had two crank failures alone. And he is bone stock.

 

Reading this has me wandering....

Nissan Titan Facelift Spied For First Time Disguised As An F-150

"Rumors also suggest the Cummins diesel option could disappear in the next couple years, leaving the 390-horsepower (291-kilowatt) 5.6-liter V8 as the only powerplant."

Rumors are just that... rumors.

 

I did a little digging on this forum and a little on Facebook group about these crankshaft failures.

From what I have found (and I just did some basic scanning), it seems all the failures I have come across are A) bone stock trucks with over 90k miles (some much higher, like 150k) or b) trucks deleted and tuned on HPP/CTT tunes, regardless of mileage.

Additionally, it seems the HPP/CTT tunes put out a touch more power than others (at least initially with its first few revisions) and also those tunes rev higher than others. I’m yet to find a PPEI truck that has broken a crankshaft. However, I did find a broken crank with Hardway tunes and also a broken crank with GDP tunes- only one of each.

Again, I’m not a scientist, but this is what I have found in my own digging. Not trying to speculate, just to discuss (and also not break my own crank).

 

How much higher are the rpms going before defueling on the CTT tunes? I'm just speculating but I doubt it's enough to cause harmonic distortion on the crank. I could be wrong just throwing it out there.

 

We need some damn trans tuning. Mine ctt has spiked on down shift and rpm build to almost 5 rpm. I pull my foot out of it when it tries to do that now and get that wuh wuh wuh sound outta the cai

 

Lubrication MAYBE. But heat soak? Come on. I’ve literally cooked engines with thermostats that failed and hot lapped race cars for nearly my whole life. Never seen heat soak snap a crankshaft.

 

No, heat soaked bearings swelling.

 

Stupid question. I'm still looking but the 5.6l is looking attractive. How is its reliability? It struggled on the ike, but with 11klbs. I'm never over 8k. This diesel thing is like a mine field, especially after owning a eco diesel. Mines been good but the failure rates are high.

 

5.6s are blowing up more than the diesels having issues.

Curious to see if that Lopez fella on here had a broken crankshaft.

Also, saw another confirmed broken crankshaft on Instagram this morning- he goes by CherokeeTitan. His dealer said ‘bad fuel’ caused his crankshaft to break.

This truck worries me lol.

How many cranks have broken on stock trucks vs tuned? Because the trend seems to me that the tuned trucks are all breaking. As for being worried, dont be, chevy has the same problem and dodge cant keep a trans in a truck. They all break

 

He was an Amsoil worshiper also....

Think about it, Ford has the powerstroke which is made in Europe by who knows, it has problems. Ford is cocky, not consumer friendly and needs to spend tons to con people into buying their product. Chevy has the duramax, God only knows where thats made, it has it's problems. Chevy(GM) was bailed out by you and I bu remains arrogant and overpriced and also needs to spend millions upon millions attempting to trick us into buying their junk.Ram(FCA) has the ecodiesel now, made in Italy(who has never made any decent auto products), it has problems. Ram(FCA) has been peddling lousy transmissions/slipshod manufacturing for decades and also spends a fortune trying to whip us up into buying their crap.Nissan has the Cummins which is made in Indiana by a company with a very rich heritage of making quality engines used in many sectors around the world. It has some problems. Nissan (Japanese) is more humble, more consumer friendly and spend virtually nothing on advertising. Most buy their (Nissan) trucks because we are not duped by slick advertising, we want quality and we dare depart from the herd mentality. Nissan/Cummins will not abandon You!!

 

No, no. I’m definitely with you- they all have their issues. My frustration is simple- I’ve had 2 Xterra’s (both 2nd gens) and 2 Frontiers and I ran all of them, except for the last Frontier, over 200k with nothing more than routine maintenance. Granted, (knock on wood) my Cummins Titan has been fault free, other than a rattle in the door

 

Cuz I'm still doing my oil changes under factory warranty to the maintenance program but when it runs out I'm going to switch my X well too and want to do the same thing with the bypass system

 

Bypass filtration does not void warranty. My nissan dealer installed mine. They think im the best customer ever cuz i pamper truck health.

Every 10k oil and insane diesel 1 micron bypass filter and stock filter changes. Did it early on as well as delete so my engine is damn near virgin. Guy on facebook has gotten 30k without changing oil and getting good oil health reports from oil laboratory. He uses 2 micron amsoil bypass. Insane folters so good - need to at least change filter every 10k

I have a 2017 5.0 cummins with 72k. My truck is used for work purposes. Only thing done to it is a SnB intake and a stereo system. Any way I was on my way to work approx 60 miles to jobsite. I exit the free way after noticing a weird sound. Soon as I come to a stop at a red light the truck shuts off and the oil light comes on. I look under the hood to see if any oil leaked out or if anything looks damaged or out of place. But everything looked good. Checked oil levels and they were fine. So i tried to crank the motor, it would crank but wouldn't start. So we tried to get it to start but in the process the batteries drained. And starter didn't have enough power to crank motor. Eventually the starter over heated and caught fire. Got it towed to nissan. After a week goes by they call me and say I need to provide maintenance records. So I did. All oil changes were done at a certified shop and only used Rotella t7 oil. After the documents were provided to nissan i get a call the next day. The advisor tells me the motor is locked up. After hearing that I begin to question the diagnosis. (How can the motor be locked up if it was trying to crank?) They didn't have a answer for that. So I asked them what the next step is. And they said we have to get a oil sample and send it to a lab to get tested. This is currently the stage I'm in right now. Truck has been at nissan for almost 3 weeks. And still no decision to repair or replace has been decided. The cherry on top is the refuse to provide a loaner vehicle for me to get work done. Instead said we dont provide loaners currently due to covid. But at the same time I see a loaner vehicle pull into the service dept. To me personally it seems like nissan is trying to weasel their way out of having to replace motor under warranty. I really liked the titan but I would never buy another nissan vehicle simply because how they are handling my warranty claim.

We'll add a 2016 to the ranks of engine failures. My engine went almost a month or so ago. The truck spun a bearing. Always used top tier oil and changed every 5000 miles. Started with a type writer tick in the mornings and afternoons until it warmed up. Took it in they said it was normal and sent me on my way. Took it to a local diesel mechanic and he thought it was an injector was going bad. Took it back to the dealer and told them what the other mechanic said and still got know where with Nissan. Went out of town a couple weeks later camping and while cruising down the interstate at 35 she started crackling real bad got off of the road shut her down. Towed to a nearby dealer. Not even a hour later from being dropped off I was told I needed a new motor. Also I was missing some parts from underneath of the truck from 2000 miles till she went. 🤷🏼‍♂️

 

Really sorry to hear that! You were pretty low mileage for a 2016 right? So should still have the powertrain warranty right? Unless the delete caused a problem with the warranty? That really sucks!

 

Have ezLynk for sale and dpf and scr as well.

 

I’m interested in the DPF and SCR where are you located?

 

Yeah it had less than 30k. Sux but what can u do

 

Sorry to hear. This is why I dumped mine while I could still get something for it in August. I also lost parts at 1200 miles. Cummins dropping the engine on all platforms spoke volumes.

 

Yeah I traded as well the day I got her back went straight to 4 different dealers and got the most and traded her in. Didn't want to but was paranoid after that.

 

For those with tuned engine failures.... what stage tune were you on? (1-5). I’d be paranoid to daily it on anything over stage 2...

 

I daily a 90HP tune. Have been for a long time now. I tow with 60HP tune.

 

Add to engine failure. 2016 XD 57000 miles bearing failure replaced engine under warranty. Nissan did all oil and fuel filler chances alone with any recommend maintenance to truck.

 

I just had engine failure the day before Thanksgiving(Broken crank). 59,800 miles. I am deleted and tuned. New engine is on the way. I will also be deleting the EGR at the same time. Sh*t happens! Rebuild and hope it doesn't happen again!

Sorry to hear that! What year is your truck (still seems to be more than a few 2016's failing early...sigh)...
