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!

[@chriss526]

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.

[@alexandermckay8594]

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.

[@ricknielson8934]

All the failures on the crank that I’ve read about are related to excessive tuning. Over 150 HP increase over stock. Larger turbo ect. I refuse to link my truck to on star.

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.

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 💪🏽

What are your thoughts of a EGR Filter to remove the soot before it does damage. Specifically, FASS has an EGR Filter that claims to do it's own regen and remove 85 percent of the soot from entering the engine. I'm not sure if the ash it would produce would be better or worse and would like a professional review that not marketing. I'm not sure where that return that they are cleaning goes... for example, you mentioned the need to clean the map sensors; would that be cleaner now if this filter was used or is that a different part of the system???

curious as to if you are running fuel additive? Are you shutting the truck off ever during a re-gen? Are you aware when the truck even re-gens? These are things that could cause your DPF to clog. Towing is one thing, but towing across town and towing to the next state over are separate things.....

I have a 24 duramax midnight edition with 21K. I have had no issues so far..... 🤞. I service it every 5K and replace all filters including the fuel filter. I also use Hotshots EDT since I took the truck off the lot. I believe many of these issues are caused when people tune and delete them. Keep maintaining them and leave them stock. Every video I see, someone is doing burnouts with their diesel truck bragging about the HP increase. These trucks come with more than enough Torque and HP. I'm not sure whey you would need upwards of 7-800 HP! I tow a 7500 lb. tractor, side X sides, & thousands of pounds of lime and fertilizer. I certainly do not need more power then what comes stock. In a nut shell, I believe most of the issues for all diesel trucks are because someone f***ked with these highly complicated engines and emission systems based on what i have seen.

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 have 24 duramax with 15k miles that turned 1 year old not too long ago. Only issue I had was one of DRL headlight had LED deadspot...probably from factory and warranty replaced it. They are 3k+ each and completely not serviceable...if a bulb goes out, you replace the whole thing. This isn't inspiring much confidence in me keeping the truck past warranty...my other cars never saw a dead headlight lightbulb in 5+ years, but they also did have a string of a zillion LEDs for DRLs. Also these fancy LED headlights aren't all that great at night either. There some software updates. 1 of them early on I had to approve and sit in truck as it happened (to fix some check engine light thing people were having that I never had), but another one I later discovered happened by itself, which is a bit concerning as I don't even know how it was able to download anything since the truck didn't have data service plan and is normally in low single zones. I replaced my fuel filter just a week ago (for which btw dealer wanted $600 to do and said should be done every oil change or 5k miles). I found a tiny bit of metal shavings on the bottom...kinda concerning, but doing some research, seems like it's normal/common thing...I have no way of knowing if it was in the fuel I purchased or the tank pump. What I don't like is the truck MPG is often inconsistent... I'll get 13 MPG one day for the same trip that I normally 18-20 MPG another day...I think it's because regen kicks in and there is nothing in tell me that. In long trips, I average 21-24 MPG. I got 21 MPG in a 250 mile trip to beach with the truck fully loaded in family and baggage/gear....700+ miles or range. Towing MPG doesn't make sense to me as well... I'll get 10-12 MPG same trip with empty trailer or it having +9000 LB on it...I'd think empty towing I should be getting better MPG, but it's just not the case. It just seems to me the truck just gets whatever MPG it chooses and my driving style or load isn't really a big factor. Towing rarely and mixed driving, my overall MPG ends up being between 17-18 MPG. Def usage has been about 2000-2500 miles per jug, or something like add a jug every 4-5 fill ups.

Just get a GM Gas, up to 6.6L if you're really haeavy towing and\or on lotss of grades. The total diesel engine is immensely complex for the average person just told RV every once in awhile the complexity of maintenance and operation and the higher cost of diesel the greater efficiency is wiped out by the higher cost right now so it's about even so the benefit is hugely more torque but and quiet are running from the standpoint of lower RPM but the issues and the maintenance and the upkeep are just way way way more than it's necessary and sensible from a cost and time and effort standpoint for an average person told an RV you know even a bunch of times a year let alone a few times. I have an older door max by the way so I know what I speak of for the general family and if you watch the video by the car wizard about 10 diesels to get the commentaries in between pretty much hold solidly if you want to hear it elsewhere if you're going to make money towing big stuff all the time and upgrades and mountains and all that get a diesel if you're just going to tell her if he wants in a while it's a recreational person it's not worth all the extra not the diesels or not phenomenal it's just not what the average everyday person needs is way too much to upkeep and keep track like keeping a DEF full keeping from plugging a DPF by not driving freeway long enough to region and all kind of stuff it's just too much it's just not worth it.

That ridiculous "PIN" problem has been on EVERY Duramax Crankshaft and Camshaft since 2001 when the first LB7 Duramax was sold to the market, GM and Isuzu has had more than 20 years to fix this problem, and the DUMBEST thing is that it is far more expensive to manufacture the Crankshafts and Camshafts with that stupid spring loaded pin, than it is to cut a simple groove into both components and cut simple woodruff keys, NOW I do agree that this setup "CAN BE" a problem on the crankshaft, but it is usually because someone does not torque it properly or enough, HOWEVER, the absolute WORST Duramax failures occur when the pin on the Camshaft gets sheared off, it is a terrible design flaw, that they have A. KNOWN about for more than 2 decades, B. could have fixed it cheaply at any time, C. NOT relied on a bunch of different small machine shops around the country to fix their own design flaws, I love the Duramax engines, I have owned a 2004 LB7, a 2006 LBZ, and a 2012 LML, and still currently own a 2009 LMM, and NO MATTER which Duramax you get, there is also 1 even more serious design flaw, that they have known about since 2001, and that is the use of those stupid torque to yield head bolts, this is quite possibly the STUPIDEST thing that ANYONE can do especially on a DIESEL engine where the cylinder pressures are so high, NOW I do admit that I am probably pretty biased, I HAVE ALWAYS HATED torque to yield bolts of any kind, and the first thing that I have told a number of friends who were contemplating buying a brand new Duramax, was to FIRST SET ASIDE $5,000 cash, and the VERY first thing they NEED to do, is spend the $700 on a FASS, or Airdog lift pump system, since they STILL have not installed a lift pump in the GM lineup, and second, IMMEDIATELY take to a reputable diesel shop and have the head gaskets replaced so that they can install the chromoly ARP head stud setup, and the sooner that they can do that the better, it DOES NOT make sense to wait till 150,000 miles or so to do it, when I bought my 2012 LML, fortunately I am a mechanic, and did the work myself, I bought the parts BEFORE I bought the truck, and I did the head gasket replacement when my brand new truck had just 61 miles on it, but I sold that truck because I DID NOT want to deal with the new CP4 pump failure and it was also BEFORE the CP3 replacement pump option was fully fleshed out, WHEN they went from the CP3 pumps to the CP4 pumps in 2011, it was the WRONG thing to do, and they are STILL coming with the CP4 pumps even though they KNOW that they are no good, and can cost the owner more than $10,000 to repair EVERYTHING that can be messed up when the CP4 pump fails, so add that one to the list of 3 CRITICAL things to do IMMEDIATELY upon buying a new Duramax today, 1. FASS or Airdog lift pump install, 2. CP4 replacement with the older reliable CP3 pump, and head gasket replacement with the ARP Chromoly head studs, IF you do these 3 things before you put 500 miles on your new Duramax, and you MAINTAIN your new Duramax, (oil changes, Transmission fluid changes, coolant changes at the proper intervals) you will likely have a wonderful reliable Duramax for more than 500,000 to 1,000,000,000 miles, but the sooner that you do these things that GM and Isuzu obviously REFUSE to fix, the happier that you will be. now you mentioned Dave's Auto Center in Centerville Utah, yes he has an AMAZING shop there, complete with full machine shop, prep area and garage with very talented techs, and YES he has led the way for critical repairs and advances on not just Duramax, but also Powerstroke and Cummins, his relationship with different manufactures have been game changers for those that he has been able to help with their problems, especially with the Duramax, the DATA that both he and Gayle Banks, as well as Lake Speed from Total Seal, have gotten while working with Speed Of Air, is incredible, NOW I can tell you, those pistons are VERY EXPENSIVE, BUT it is the 1 component that has paid me back the huge price tag that I paid for them, if you would have told me 20 years ago, that I would one days spend more than $4,000 on a set of 8 pistons, I would likely have slapped you, but looking back over the past 2 years, it was the very best AUTO related expense that I have paid for and would happily do it again. the MAIN reason why I have sold my newer LML and stayed with my LMM is that stupid CP4 pump, and have had no desire to buy any LML or L5P or anything Duramax powered that is 2011 or newer, the 2007.5 to 2010 model years was as good of a Duramax as you could have ever gotten, now you are talking about this new computer system, which makes me even more wanting to stay FAR away from them now. WHO knows how long it will take to find an acceptable solution to that nightmare?

[@paulmcintosh5535]

So, you say pretty common issues. Just how many? Probably less than .5% of Duramax on the road.

[@RobertKohut]

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?

[@MechE11B]

They collect all your driver data and sell it to insurance companies. They are currently getting sued by the State of Texas for doing this without customer consent.

[@speedy4829]

Price and complexity increases coincides with more problems. Who would have thought!

[@GettysGarage]

price is a large issues indeed these days.

[@JasonBoyd-m1k]

I'm really hung up on diesel vs gas

[@DIYnService]

If you put it on weight loss, GM will report you. No thanks, It's Ford or Ram. Keep your GM.

[@jsuperman7672]

Just like onstar , dont get it. They report your driving habits to your insurance company, then they raise your rates

[@barrylenoble6705]

Would you recommend a Fass fuel pump?

[@ondago2]

Not necessary the L5P has a lift pump I think fast sells something for it but it's not needed like the previous generations

[@1958johndeere620]

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.

[@GettysGarage]

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.

How do you feel about the Sany yellow iron?

Was there really anything you liked????

[@2007dalin]

for dozens of reasons i wouldn't touch a chevy with a 45 ft pole

[@Anonymous..VQ3.5Lg35]

New ford 6.7 needs new main bearings after 200,000 thousand probably, l5p is the best built stock motor capable over 1000hp ez!

[@GettysGarage]

the L5P has a very solid bottom end.

[@gtapps739]

I turned all my ota data sharing off. F them. Went to dealer and they turned it back on. Called and they said GM makes them. Turned it back off.

[@markmarcus4828]

P.S. the harmonic balancer is night and day better then Dodges that RUSTS off and destroys the engine.

[@nlitend1]

Banks makes a maf spacer.

[@GettysGarage]

I'll take a look!!

[@jonathonsantamont8527]

S and B as well. Do they actually work? I just pull and clean mine…. Always been pretty easy….

[@markmarcus4828]

I get how some people find what he says to be true but he is no engineer. No mechanic is by FAR. And i can say that they HDs go far beyond his scope of understanding. All he can really do is turn a wrench and repeat what hes learned in school. Go to Banks channel is you REALLY want to see what makes this engine the best.

[@fvasque1]

If you want to play, you got to pay!

[@RobertKohut]

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!!!!!!!!!!!

[@MechE11B]

You will own nothing and be happy about it.

[@evoemperor3776]

With all the epa crap on diesel engines i think cummins 6.7 would be a way better engine for ease of maintenance and repairs. These v8 diesel from ford and chevy looks like a nightmare to own.

[@joehooper1145]

How many people have problems with these trucks, and DONT daily them and tow with them frequently? I’ve always heard a hard worked diesel gets to becomes a high mileage diesel. Garage princess’s have all the problems

[@clivemacmurray3899]

I feel like this is super true I tow 7 tons at least twice a week and always driving with good size loads in the bed the emission system likes to be hot that’s when I feel like you get the least problems - 2024 l5p

[@Austin152-S]

Klouse Shwab gets to turn of your engine when you don't eat z bugs!

[@sstoner911]

About 95% of the issues he is talking about happens across all Diesel Platforms across all brands occasionally. Everything man made is prone to breaking.

[@RobertKohut]

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!!!

[@mike_holdread]

Updated junk. Nanny software, no.

[@hbr6192]

A lot more diesel consumption vs 2022. I regret the change.

[@GettysGarage]

A number of people have mentioned that. Potentially more frequent regens ?

[@jonathonsantamont8527]

2024 vs 2019 here…. Easily twice as many regens. I have not seen a huge drop in fuel economy between the two….

[@juanmartinezinc59]

Mine leaks oil like a mother

[@tammyspencer9786]

it outpulls any cummins period.

[@Mr.frag-out]

You mean they can track and deactivate your vehical without your knowledge.

[@williamghiatis6739]

Listen, if guys from Norway figured out how to tune a DME in a BMW, they will find a way around it....
