- I Review the New 2024 Chevy/GMC 2500 HD 6.6L Duramax Diesel L5P Engine. I discuss everything Wrong with the second gen L5P Duramax diesel including Fueling issues, Aftertreatment and Emission related issues, the New Global B Electronic system in these HD trucks, I also go over the MAP sensor issues and Injector Connection issues with the L5P Duramax Diesels.

The1 first Issues for these updated second gen L5P duramax engines is a fueling problem. when these engines first came out in 2023 they were getting poor fuel economy and at times running rough. turned out there was some faulty software causing the injectors to over-fuel and the recall was released by GM to correct this software bug.
the next issues or concern is the New electronic system that is in the 2024 HD truck platform known as Global B. this complex electrical system allows for over the air software updates and in my opinion has potentially contributed to a greater amount of check engine lights.
Thirdly is the MAP sensor getting clogged with soot, pretty easy fix but certainly something to keep an eye on.
the fourth issues involved the injector 4 on these duramax engines, the connector was fail causing a missfire on the first gen L5P diesel engines. GM released an service bulletin and this has hopefully resolved this issues going forward with these new engines.
the last issues and maybe the most contiversial is the crankshaft pins breaking causing engine failure. aparently the dowel pins holding on the timing gears and harmonic balancer can fail and cause engine failure. I give you my opinon on this.
lastly I quickly discuss how I wish the duramax stroke was longer something like what ford has done to help create torque.
Hope you guys liked the video.

I have a 24 L5P, stock, with a little over 20k miles. Half of that towing. I’ve had no issues at all. Tows up the western mountains with ease. I am very pleased with the truck, 10 speed trany and the engine.
First selling driver habits info to insurance companies and now monitoring you if you make mods to something you paid a minimum of $70k for to last longer. Screw General Motors.
The EPA sucks. Please vote any supporters of emissions controls out of office. We need to roll backwards on this.
It is what it is. I understand the concern for pollutants but at this point diesel engines are running extremely clean and the idea of tightening up missions even further seems a bit much
I can concour to that. They're still using the old engine logo with a carburetor and air cleaner on top. That's how dated the epa rules n regulations are
Greetings Alex.
for now; I feel much more reliable than the 6.7 liter Cummins. But you have to remember that nothing is perfect! Your information and support as well as your comments are great. Thank you so much! 😊
Voting system is rigged towards democrats, we live in a dictatorship
EPA = DEEP STATE.
Makes me want to keep my old 1995 gmc 2500
I have a new 6.6 gas 3500 dually. I've put over 60,000 mi on it in just over a year. I tow 6 days a week. This truck has been worked very hard and has literally had zero issues. If you're towing under 15,000 lb and need a high payload I definitely recommend the 6.6 gas.
the 6.6L gas isn't anything pretty but it seems like a pretty solid work horse.
@@TheGettyAdventures give me a work truck that'll go +300k miles with no headache and I'm happy. I'd love to see more on the new Ford 6.8
Incredible film Mr. Getty 👏👏 Have a great weekend sir 👏
Also would like to add, thank you for your information on ( Map) sensor 😊 YES I have taken mine off, not as dirty as the one you show, but boy it's so easy and simple to unbolt, clean, and make it pretty again
A big thank you for showing that service that any owner can do on their own. Another thing I do is raise the hood and let the rain water drain from the Rubber Boot attached to the hood. I just like to get rid of that water just about every time I start my baby 😊
have a great weekend my sir
Thank you for updating information on
Chevy ( GM) Duramax Diesel PU engine
Although my Silverado Z-71 3500 Duramax
Is a 2021. Bought it used with about 10 thousand miles on her. I love my 8 foot bed and 4 door. It is also white. The most useful thing for me is the 4 side step up for bed of box.😊❤😊
The OTA updates are an issue with f150s as well. On my 21 3.0 Powerstroke, I’ve only had one update come through since new and there have been countless updates apparently pushed out over that course of time. But hearing about guys getting OTA updates and then things stop working (head units brick, running lights malfunction, etc), I’ve actually turned off the auto updates altogether…..don’t want them. My fear is that now that the warranty is up, whatever ford screws up with an update will be on my dime to fix and I’m not ok with that.
Always great info. 👍👍
Thank you sir.
I’ve always found it funny whenever people comment “I’ll keep my 7.3” on videos reviewing new trucks, however I’m starting to see why people are hating newer trucks. I have a 2017 L5P for a personal truck that I think I’m going to keep forever now. I really believe besides those and the 17-19 super duties will be the last good diesels ever made
I’ll keep my Ford Model A thank you. Never had a check engine light on that horseless carriage!
Covid killed the quality of damn near everything
I have a 65 C10 I'll just keep forever. The engine has never turned on... It's amazing 😅
I hear alot of people having good luck with those early L5P engines. and yes Covid did seem to kill alot of quality for a numbers of reasons it seems.
My 2024 HD Ultimate made it 1 mile from dealership before check engine light and Christmas tree. Bad sensor front right, fixed day later. Concerning that these types of things are commonplace .
Great information, good stuff! An over-the-air update caused my 2022 F-150 King Ranch 5.0 to spend over a week in the shop. They pushed an update that told the truck it had a feature it didn't (park assist). Was an absolute mess, thet had to send an engineer to fix it, told me to disable updates for a "while". I'm convinced it was a mistake by some rookie developer. Looking forward to the next video!
Gm Duramax trucks are the best tow trucks hands down.
Very reasonable presentation 👏
Thank you sir.
More like “over the air turn your truck off when your social credit score drops below 500”
Somehow we’ve gotten by just fine with air gapped transportation since we started riding horses, no need to start connecting things now
haha maybe something like that.
I had my 24 for 4 months and put 20000 miles on it, better then the 24 Ford power stroke I got rid of, with nothing but trouble I had with the engine.
I've had a 1972 Chevy C10, a 2023 Chevy 2500 6.6L Gas and now am about to trade to a 2024 Chevy 2500 Duramax. I didn't know about the Global issue. Thanks for the info. I miss the good old days where trucks were made for work and not overengineered. One question I have is, I had a pedal commander on my 2023 500 gas and it worked great. I plan to add a pedal monster onto the Duramax. Since all it does is increase throttle response I don't believe it should affect it negatively. I am curious what your opinion would be.
OTA software updates... what could POSSIBLY GO WRONG?
As a 6.6L owner, I have to say it's easily one of the trucks ever produced.
Putting heavy workload miles on it day after day, has taught me that it has the gm engine recently made, maybe even of all time!
Lmao
Yeah it's a truck and it has an engine. Your insight is truly mind expanding and impactful. I'm for your comments and you.
It’s definitely a truck, heck yeah.
Plus GM doesn’t make the engine
Oh hands down. It's one of them.
for a RV need, which kind of truck would you recommend?
How do you feel about the Sany yellow iron?
Alex, what do you think about wet belt engines. Not just DuraMax, any of them. I've heard that Ford is having a hell of a time in the U.K. with their small diesels not being able to make past 100K miles because the oil system gets clogged from the belt disintegrating and the engine goes. And they're not warrantying it. The theory goes that if they do it once it'll open such a can of worms and cost them a fortune, that they deny any claims.
When we are already making near 1000 lbs/feet of torque, the under vs over square starts to become less important. The l5p is a solid engine and should definately be a consideration for anyone looking to haul
Global B gives me the feeling like you never really own your truck.
I get that there’s many great advantages to these new trucks and the engineering in them, but there’s also downsides.
I don’t mean to be a conspiracy theorist lol
100% agree, no conspiracy theories but it is a little weird to think of something being able to “hack” into your truck
I work in tech so I’m not scared of it. I hate subscriptions, don’t get me wrong. But the benefits you get from telemetry data, remote diagnosis, and constant software updates makes it more than worth it to me. I also don’t blame any of the “give me a steering wheel and a pedal with none of that computer crap” crowd, especially when they really don’t understand software technology at all. Just know anything that comes with your truck today can’t suddenly become a subscription. So there is no “my truck isn’t mine”. But by all means simply disconnecting the fuses that use cellular will be more then enough to keep the tin foil bag folk happy. I for one am crossing my fingers for an OTA update that’s gives me full screen CarPlay and more guages in my instrument cluster. The power of this platform 💪🏽
Wait until you realize it's just not trucks. Planes are vulnerable also, and that is scary as shit.

BIG HUG! 😮
Would you recommend a Fass fuel pump?
The Chevy Colorado's have also had issues bricking from the battery being killed after the OTA updates went goofy.
who would of thought eh lol
Does the global b apply to the gas l8t gas engine as well?
Ya I figured there’d be some hiccups and issues with the updated engine. I ended up not waiting and picked up my 2022 Silverado HD diesel.
Solid unit forsure. nothing wrong with that.
My 21 f150 had multiple ota updates so i took to dealer for an update. The update was supposed to take 2 or 3 hours. It sat updating for 22 hours. They were afraid it would brick if the stopped so we let it go. It didnt solve all the issues that the update was supposed to take care of. I just live with the electrical annoyances. Lease ends in oct this year. Not sure which way to go.
nothing. ever
Did Claus Schwab have a hand in this truck's development?
you still got that ridgeline? i wanna see another video of it!
Odd that the Duramax wouldn't shut off if the oil pump is not turning making pressure since most modern engine do shut off due to no pressure thanks to fail safes built in, although if the oil is getting old and starts to thicken then that could be part of the problem. Most people just fuel it and go with no thought of ever performing basic maintenance that's why so many vehicles end up junked with low mileage.
I think deleted 2020-2023 duramaxes will be seen as the epitome of the modern diesel era.
They are very reliable, and the delete in Canada is about $5k all in.
The trucks themselves have all the things a truck needs, there isn't anything better than can be added, so there is no downside to owning the slightly older model.
The first gen L5P engines are solid units. no major issues, aside from some minor hiccups.
Bought a ‘24 Duramax and the first thing I did was install a MAP sensor spacer. Curious to see how that works out in 20k miles.
Why I left mine alone put 120k no issues
@@anthonymckenzie4234 yeah I wonder if this is all a bunch of TH-cam/social media drama.
Short stroke has its advantages too.
It does, the ability to rev higher and faster, less inertial load on the rotating assembly. all of which is great for creating high end power. However in a diesel HD truck I'd take low end high torque grunt over top end performance all day.
I’ll keep my 7.3 🤘😎
Why have egr with epf?
I'm really hung up on diesel vs gas
Price and complexity increases coincides with more problems. Who would have thought!
price is a large issues indeed these days.
My 24 AT4 seemed to be burning way more fuel than previous. (my 6th Dmax)
Imagine that software update done remotely. Guess better chk with dealer.
Ya it would't hurt, the second gen L5P's may also just drink more fuel, heard a number of people discussing much higher Regen frequency
The pin is just used as a guide, the bolt is supposed to hold everything
That is what I presumed as well.
brand new 100k truck acting up anywhere, anytime for any reason...way to go GM
Why do they need to update software on vehicles? It’s not like the purpose of the vehicle is going to change.
lol well from experience, what happens is for example a vehicle will be released and they find out that the fuel map is slighly off causing engines codes or aftertreatment codes and so they need to update the computers to change the fuel mapping. stuff like that is the main reason for software updates. helps to Iron out kinks.
I’ll keep my 2013 🇺🇸 HD2500 gas 6.0 4x4 with 220k miles. still pulling strong ✊
Who Can AFFORD these ?
the average person can't afford these anymore.
Why does a truck need to be protected from "unauthorized access to customer data"? Why have any data about the customer? What kind of data are they collecting? Are they sharing any data?
for dozens of reasons i wouldn't touch a chevy with a 45 ft pole
Just like onstar , dont get it. They report your driving habits to your insurance company, then they raise your rates
my 17 just ate 2 lifters and fucked up the cam. Its rare, but documented
Interesting, I see what I can dig up.
@@TheGettyAdventures i have a picture of the lifter. I caught it early so it didnt look too crazy.
Klouse Shwab gets to turn of your engine when you don't eat z bugs!
Imagine I buy a PC with Windows installed on it. Then I decide I want to try Linux on it. I install Linux but when I do the PC no longer works since I tried to change the OS. WoW!!!
Banks makes a maf spacer.
I'll take a look!!
S and B as well. Do they actually work? I just pull and clean mine…. Always been pretty easy….
Wow!! Are you buying the truck or are you renting it. How can they control how you tune it? It's not their truck once you buy it!!!!!!!!!!!
Now the crankshaft is the #1 issue…..beware!!!!
New ford 6.7 needs new main bearings after 200,000 thousand probably, l5p is the best built stock motor capable over 1000hp ez!
the L5P has a very solid bottom end.
Absolutely no reason the big 3 can't put out a bulletproof diesel motor on this modern era. Instead of focusing on making more horsepower and torque, they should fully abuse the engines for 2 years and make a good product
Maybe me and you would appreciate that, but I think for the average buyer, more power = better.
A lot more diesel consumption vs 2022.
I regret the change.
A number of people have mentioned that. Potentially more frequent regens ?
2024 vs 2019 here…. Easily twice as many regens. I have not seen a huge drop in fuel economy between the two….
That's a government kill switch
Something like that
@TheGettyAdventures no it is. It was mandated in legislation per the "Inflation reduction act"
Updated junk. Nanny software, no.
The Global B is much more about receiving data from you than the other way around. They can keep their trash intrusion. I will go back to a carb and points. The diesel emissions have ruined all the diesel trucks.
Agreed, there is something weird about having the ability for someone to access your truck remotely.
@TheGettyAdventures its all about big G having control over everyone.
(Big Government)
Was there really anything you liked????
Not a big fan of OTA updates for my vehicles, at least in any fashion that can inhibit driving ability.
Crank pin sheering will keep these off the farm for sure 😂 another grenade by gm. Someone will have to die before they fix any of it too.
It's a weird one forsure, Personally I think it's a little overblown but obviously something to look into!
ho, yah i will have a truck that is controlled by someone else... think not
I wouldn’t say controlled but a third party can gain access to the truck which I agree is a little odd.
You’re right. You are winging it as some without an engineering background.
Vehicles have been able to be hacked into for years. Do you forget the whole Ram debacle where they could be hacked into and controlled? That was years ago… don’t pretend like this is something new
Told you the crank pin sheered on this 🗑️
@@freedomisntfree_44 if you watched you would know it’s not a common issue and the one that did the harmonic balancer wasn’t torqued correctly causes the problem. Please show us more than 3 of these

I guess my point was that this new electronic back bone may be causing these check engines lights, lol and figured I would touch on the system itself.
So, the Chinese have hacked the engine and Mary should retire?
This sounds like a disaster waiting to happen
100,000.00 worth of junk.
L5p is the best diesel engine ever put in a pickup not at all junk
Your clueless good luck with your v6
Weird way to say you can’t afford one
@@JoshuaOvermanFords 6.7 is miles ahead of the 6.6. The 23 gmc I drive is so slow 😂
@@waterloo123100the duramax doesn’t have piles of blown engines laying around like the 6.7 power stroke does :)
Buy a gas engine…..did you hear this??….wow
Hey Big 3, it is a pickup truck, not a fucking Boeing 747 plane. Quit making these vehicles needlessly complicated.
Im not sure about your videos, you say Cummins has a longer stroke for more torque and yet the shorter stroke 24 l5p has way more torque than cummins. Definitely need to separate your opinion from fact. P.S. i am also a technician
The HO 6.7 makes 1075 lb ft of torque. That’s a 100 more than the 24 l5p. You definitely need to separate your opinion from fact. Kinda embarrassing from a tech.
So torque generation relies a number of factors, but it is very well documented that an engine with a larger stroke has a better advantage of producing torque over a shorter stroke engine.
@Lq32332 don't take my comment out of text, I was not denying longer stroke can produce more torque. Dale Banks tore down a 24 l5p and was highly impressed with the upgrades and design of the engine. As far as the ho 6.7l, you can't get that in a 2500 pickup. By the way, I'm not embarrassed lol
@@Steve-rf3rn Even the SO cummins has more torque per cylinder. 850 ft-lb / 6 = 141.6 ft-lb per cylinder. l5p is 975 / 8 = 121.8 ft-lb per cylnder. The SO powerstroke is 131.2 so the refreshed duramax still has the LEAST torque per cylinder.
@@Lq32332 your an idiot lol
I dont like that they are not an inline 6. Id go GM hd 6.6 gas over a dmax.
Inline 6 in my opinion is an optimal diesel engine design. But I think the issue is the length of the engines. They may not be able fit them into the engine bays which is why GM and Ford may have gone with the V8
@@TheGettyAdventures when GM was looking for an engine to replace the 6.5, at least one inline 6 was sent to them - a John Deere Powertech. But the v8 obsessed meatheads at GM had to go with a v8.
