The MOST Common Issues with Cummins X15

[@costa1967]

Currently I am driving Volvo, but I worked as a tech at KW for a long time and I tell you, there is no such issues with x15. Have not seen single fuel pump failure over the years! Engine noisy and vibrates at idle, but this is about it. Not mentioning aftertreatment system, because this is to certain extent not exactly engine itself. So lets not spread those baseless rumors. Also I wonder how filter clogging could be Cummins issue.

[@flounder5946]

Filter clogging sounds like a company or newer person not putting anti gel in their tanks. I've met a person who never put anti gel in their freight line. Used diesel 911. Said that was for last ditch and should be using anti gel when it's below 20 degrees. I've idled my paccar quite a bit. No apu. Only had to replace the egr aftertreatment once in almost 5 or 6 years. And mine is a used 15 pete. I pretty sure it was factory egr to.

[@mikeshultz1007]

I have seen many problems with the isx15 and x15, the fuel pump gear does have a tendency to spin on the pump shaft. I use loctite 620 when reinstalling the pump gear and I have not had any issues with them.

[@angrysocialjusticewarrior]

You've also never seen a truck explode. So by your logic this means no truck ever explodes because you have seen plenty of trucks in the shop that have never exploded or caught fire right?

[@meminustherandomgooglenumbers]

The Cummins fuel pump issue only pertains to about 2800 engines. Recall notices were sent out a while ago, or you can call in to see if yours is recalled. If so, bring it in and they'll replace it at no cost to you.

[@costa1967]

@@angrysocialjusticewarrior You are correct. Trucks do not explode and usually do not get caught on fire if used and maintained properly.

In Western Australia we run the X15 in Qaud road trains grossing 210 tonnes. We can't get 12 months without them blowing up. Set at 600hp running 24/7 yet Volvo at 700hp will do 5 years without touching the engine. We all hate the red engines. Wish Cat would come back in to the game as we have many issues in that 1 year mainly after treatment issues not to mention timing gear failure.

[@josephquattrocchi5620]

I have 2 Isx 15 liters and experienced the fuel clogging the filter. I found my cause to be the cold air from the fan and under the truck. So I covered my filter housing with a plastic bag and fastened it in place with tie wraps. I have never had the problem since.

[@ltslogging3776]

I had a 2018 x15. They only thing I had go wrong in 10000 hours was a EGR cooler. Was a great motor. So far the 2022 is even better 🤞🏻

[@TruckingToPlease]

Our 2020 X15 gels fuel at 25f but generally the fuel supplier's winter mix or bio-fuel percentages. We normally carry 2 sets of filters for everything.

[@topdoglogistics1406]

Love our X15

[@meminustherandomgooglenumbers]

The x15 fuel pump issue is completely different than the issue with the ISX common rail fuel pump. On the ISX's with common rail fuel injection, you want to rebuild the fuel pump every 250k-300k, mainly to replace the plungers, but it's a fairly cheap rebuild even if you go all in. The x15 fuel pump problem only affects about 2800 engines. What happens is the pump's drive gear slips on the drive shaft so it stops pumping good. It's a less common problem since it's only on certain engines, it has way less potential for blowing up the engine, and the recall replacement should fix it.

[@michaelwright1602]

Like in liners? Lugging the motor? Running under load below 1500 rpm? Do that, and the #5 liner will break loose. RPMs need to be kept above 1500, if you have an automatic transmission that is set up to lug the motor, have it reprogrammed.

[@HarryC786]

It's not x15 veer. It's fuel quality. Not just yours it's on every x15 Pete. 2 filters definitely.

[@michaelwright1602]

The fuel pump issues are very real, it is best to rebuild them at roughly 400,000 miles. This is for the CM-2250, CM-2350 and new X-15. Cummins does not build the fuel pumps, I believe Borg Warner does. This is a known issue that no one has been able to solve. Ceramic plungers or steel plungers, they all eventually fail, so rebuild them. And if you ever get a fuel warning light, hit the shoulder and shut her down. The damage can be extensive and expensive, even with the oil circuit being taken out of the newer models. You will still have metal shrapnel in the motor, and more than likely loose all 6 injectors. The fuel gelling? Not an issue that I have ever heard of, may have been a location issue, especially in the temps you were experiencing at the time. Most drivers and O/O do not even know what PowerService is, or any of the other flavors for that matter. The emissions, the Cummins is very easy to maintain if you have a copy of Insite and an Inline 6 reader, both are readily available on eBay for the entire kit, around $250 delivered. Regular EGR Tuneups will keep you out of trouble. Best to remove and clean the EGR Valve and Cooler every few years too. Then the service intervals, 10,000 to 18,000 miles, depending upon usage and conditions. Play around with extended oil changes, and you will be in the poor house when all of that soot catches up to you. In frames start at $28,000. Best to purchase one of the Amsoil Universal remote oil filter kits and run that along with the oil filter on the motor, help keep those soot levels low. Amsoil filters are not required, just find a filter that fits. Then the two main sensors that everyone neglects, the sensors that always has Cummins turbos on back order, the Intake Manifold Pressure Sensor and the Exhaust Back Pressure Sensor. Both are easy to replace in a parking lot with a 10mm socket for the intake sensor, and a 1 1/8 inch socket for the back pressure sensor. Many turbos, at +/- $8000 a pop, are sold to unsuspecting truck owners, quite the racket these shops have going... And when you come back, they nail you for another $4000 +/- when they replace the EGR Cooler... And when you come back again, they tell you you need an in frame... That is how it works folks, when all you needed were two sensors, roughly $300 out of pocket and a few minutes of your time in the parking lot or truck stop to install them. Those blown head gaskets? Drive the truck the way it was engineered to be driven. When under a load, the rpms need to be kept at 1500 and above. Due to the design of the motor, when you lug the motor, say in that 1200 rpm range, under a load, the rods and pistons simply beat the cylinders out of their perch on the tiny ledge they sit upon. Keep the rpms up, stay out of the shop. In frames start at $28,000. The other incentive to own a Cummins, is the fact that they give you all of the manuals for your particular motor via the Engine Serial Number on their website, Cummins QuickServe, all for FREE!. All of the instructions to properly diagnose, repair and even rebuild the motor in your driveway. All of the parts catalogs, specific to your motor, along with torque specs, electrical schematics, sensors along with the needed part numbers for any speciality tools you will need to accomplish the task at hand. No other manufacturer does that. Cummins fan boy here, for good reason. Mine just rolled 1.1 million miles.

[@rickcross7888]

I just got a 2019 579 with a Cummins. Switched from Volvo finally.... I had similar issues with my manifold sensors and carried spare ones and anyone without a 10mm wrench and socket should not own a truck. The Volvo enables you to access the trouble codes on the dash and once the problem was fixed the light went out. But My problem was when I had weird problems with it suddenly going into Derate only Volvo could do a forced Regen and reset the code. Luckily I never got stranded on the road because I just unplugged the speed sensor and could still go 65 with less power no speedo or cruise control of course. But I could get home or to a Volvo dealership. My question is can I clear Derate codes with the tools you mentioned. And could you please send me a link to the best ones to purchase that I can carry with me for road side repairs. Thanks I would love to talk to you if you have time Rick Cross 763-744-6086

My 2014 pete with the isx15 it never suffered any of those problems, it did suffer from the cam hardening failing that was a problem from 2013-2017 and the biggest thing that killed my truck was being deleted! It had a bad tune, pulling 140,000lbs day in and day out through the canadian rockies did some serious damage. Took 14 months for it to drop valves seats and destroy almost everything. I'd very much so recommend not deleting an emissions truck, instead just don't idle it. I'd take another cummins in a heart beat no question about it, had more power then any other truck I'd driven which includes all the old school favorites 3406, 60 series, dd15, just not the n14 as I'd never had a truck with one yet. My paccar mx13 is dead set reliable, they really are bullet proof engines between 2014-2017 even with questionable maintenance. Just no power and no better fuel economy than I got out of my isx15.

[@tba3900]

I run Kenworth’s with x15 and signatures 625 before that. Never had issues with either.. PS you Detroit are not Detroits it’s a Mercedes’ engine.

[@PlayWaves1]

If I ever buy a truck it's gonna be a DD16.

[@Road-To-Destination.]

Will take Cummins/paccar vs Detroit. As a package, freightshaker does not provide anything as good as competition.

[@bighorn9119]

I feel it's poor maintenance and also I wouldn't really get this from a driver well you can but it's better to get this information from a mechanic who actually works on

[@mewithouttherandomnumbers]

The fuel filter issue might be related to the problem where Paccar was ordering Cummins engines and putting the smaller, cheaper Paccar fuel filter system on them, even though Cummins specifically calls for Davco filter system. And then Paccar wouldn't warranty the problem, falsely claiming that it was Cummins fault.

[@대격변이퍽내가바로]

wow that is a crappy response from Paccar

[@Manofwar9431]

Have a c15 with over 45k hours i high idle the truck when I sleep

[@JT-ko3rv]

To bad Daimler ,Bastardized the Detroit this DD15 is a gutless pile. Miss the cummins so much and it got over 1mpg better cause it ran at part throttle all day effortlessly. The Detroit has its tongue hanging out to the floor just to get and keep the load moving lol

[@sandasturner9529]

I want an x15 Cummins.

[@davidgonzalez1404]

I have a Volvo with a Cummins and my dpf module catylist blew up and now my truck has been in the shop since may because they don’t have any and they keep telling me they don’t know what to tell me and I’m about to lose my truck to the bank … Cummins suck and will leave you out to dry

[@catdaddy3728]

Slide underneath the old girl with a metric adjustable wrench, and check those flywheel bolts...

[@larrybroad8746]

hello well as for the x15 it is a complete redesign from the isx not one part from these engines will interchange get the facts correct

[@williamkiser5611]

Detroit engines biggest problem is that it’s put in a freightliner…

[@NorthAmerican-Trucking-News]

Heh?

[@JakeLashaway]

Good old 12v Cummins the best

[@umadbrooo6947]

Looks like we have a Cummins hatter

[@kennardjohnson7875]

Detroit is the only engine I have ever blown up. Yes I've put a lot of money in my Cummins, it's left me on the side of the road.

[@Prachka1]

Biggest problem with Cummins is not as close as a biggest problem with DD motors. First, dd is in the Freightliner/western star - two of the worst trucks in the country. As far as Cummins, can be gotten in any chassis. Cummins is the strongest pulling engine out there now. Now, DPF? - yes, they all suck. DD SUCKS with power and drivability, wouldn’t want to have one .

[@ryanreinhart1834]

Your opinion is purely that. My Detroit 60 series is the best , smoothest and strongest pulling engine. You can easily search it up that Detroits pull harder up hills. Cummins are tractor engines, there are noisy and vibrate much more than a smooth running Detroit. With a DD16 out performing am ISX15 easily.

[@Prachka1]

ryan reinhart , that is why dd15/16 powered chassis are sold at a discount when compared to a Cummins powered one.

[@ryanreinhart1834]

@@Prachka1 no. Actually it's because Cummins are built separately from other chassis, as Detroit's are built in House. Also Daimler is much Larger company than Paccar or Cummins and have lower Manufacturing costs. You see Cummins sells engines to Kenworth/Paccar and Volvo for a Profit where as Detroit is built and sold by the Supplier themselves, Freightliner/Daimler. I guess you just don't understand the dynamic of inhouse building. This would be why Cummins has bought Meritor this week. Same reasons.

[@Prachka1]

ryan reinhart, drove them all. Detroit is the weakest of them all, power delivery wise. Again, there is a reason why, primarily, only larger companies where drivers either can’t drive or do not care about driving, have detroits. Outside of 12.7, primarily for electronic reasons, are in demand on the used market. Anything over 12.7 and their demand falls through just like a demand for a Freightliner product, in the used market. People that buy them are either noobs out of schools or starting out. So, take it for what it is. Detroit has displacement and no delivery.

[@ryanreinhart1834]

@@Prachka1 😆 funny cause Freighliner has 40% of all truck sales #1 seller and the Detroit 60 series is the top selling engine. Paccar Motors blow head gaskets, Cummins is nothing special either. All these engines are or were owned by GM, there is zero Fundemental difference between them. It's purely brand preference.

[@Suntan330]

Seen more trucks with Detroits in them burned down to the frame but you want to hammer Cummings.

[@MerlinMoorlo]

New X15 still crap? I mean that verision of engine what goes with new Peterbilts

[@sonubrar6067]

I have 2016 800k mile stil running good but one time fuel ⛽️ pump part replaced arraund 450k mile

[@sonubrar6067]

It’s x15

[@dieseldummy3277]

Just the guys opinion, he doesn't know a damn thing about a cummins, he's stuck with that weak ass Detroit-Mercedes junk.

[@alexandruapostol]

That is isx15 not x15 ,what are you talking about???

[@NorthAmerican-Trucking-News]

?

[@Ridinglawnmower145]

Out of this whole video all I got was fuel pump which isn’t even true clogged filters on cold weather must be the drivers dumping additives clogging the filter and you literally said all trucks have the emisión issue but someone it’s Cummins only even though paccar have more issues than Cummins with the def system
