These pumps fail on all models GM, Ford and Dodge , my thoughts are the fuel that is being made today doesn’t have the lubricants in it , like that old diesel fuel , the government is responsible for this

[@efeola]

Realistically this should be a recall on every truck that has this pump in it. Thanks for the info!

It really isn’t that serious

[@efeola]

It makes me wonder about Ford that has been using the CP4 since 2011 and continues to on all the 6.7 Powerstrokes. They may have a lift pump where GM did not but the CP4 is none the less destined to fail with an inherent design flaw. Ford should be very concerned.

[@Duramaxtransporter]

I have a 2016 GMC 2500 Denali with 353k miles on it. I use it for RV transport and so most of it is highway mileage. At 332k miles my cp4 went bad. Took it to a GM dealer and they replaced it with a new cp4 pump, but did not do fuel system or injectors as they told me there was no metal in the system. This happened this past July 2024. Cost out for the work came to $4k. Fast forward to the end of September and the truck hit 353k miles and the cp4 pump went bad again. Just a little over 20k miles on the new pump. This time the pump grenaded. Metal all through the lines, injectors, and fuel system. Of course the work that was just done would be under warranty…..you would think. Took truck to the same GM dealer that did the work back in July and was told that the cp4 pump went bad again. The only problem…..they would not warranty anything beyond the pump. I was told it would cost $7k to do this repair. The dealer would not even submit paperwork for the warranty because of the failure and I was told that it was not covered. The truck did not stay there and I ended up having it towed to another local diesel shop and they are doing a Cp3 conversion along with the disaster kit, also having it tuned and deleted, full 5 inch exhaust, also adding down pipe and lb7 up pipe and a lift pump. Cost for this comes to $11k, but this time being done correctly. Unfortunately I am from Indiana and not under this lawsuit so everything is out of my pocket. For all those that have an lml Duramax……. Get a cp3 conversion asap. Even if it has low mileage, that cp4 will fail eventually. Save yourself thousands of dollars now rather than spending all your hard earned money later. GM knows they have bad pumps installed on these trucks and don’t want to pay for the problems.

[@Skyhawk172m1]

Have a 2016 Chev 2500HD with the effected 6.6 that I bought new in AZ. That being said my truck doesn't qualify. But I was pro active I installed a lift pump and used additives every fill up. When the truck was finally out of the extended warranty at around 40,000 miles I decided that the fear of total failure was to much as I use it to pull our 34ft. 5th wheel. Being a retired aircraft mechanic I decided to do the CP 3 conversion. I bought the Fleece kit and spent 10 days in my garage doing the conversion. I've put close to 3000 miles on it since then and I can say I'm extremely happy that I did the conversion. Shame on GM for sticking it to so many of their loyal customers. Several GM dealers have contacted me to see if I'm ready to upgrade, my usual response is not a chance, GM has lost another customer.

[@HardEnduroLlewellyn]

I’m in Pa, got the postcard last week. 16’ Denali.. I submitted my info, waiting to hear back. Will let you know. Got my truck at 40k and did a 165 lift pump and “other stuff” including pump saver at 100k. Use fuel additive every fill. 181k so far so good. Should be reimbursed for the stress and all the premeditated maintenance bs I spent.

I bought my 2008 LMM in 2014, with a 100k on it( Wife wanted a bigger trailer.) Never owned a diesel, didn't know shit about them!! After about 5000 miles ran into a diesel mechanic that gave me the scoop and he deleted the DEF system. Installed an EFI live, put it on number 2 Increased my fuel mileage running empty from 17 to 22. Put a fast fuel system on and I religiously running fuel additive every tank. Kept the stock fuel filter. Change it every 5000 with oil change and changing the fast fuel filters every 15.k Looked into spending 80K on a new one. No freakin way mine is paid off.

CP3 pump conversion is the best option for the 11-16 LML Duramax and 19-20 6.7 Cummins. But 6.7 Powerstroke, it will go with the DCR Pump conversion.

[@justinlinscheid813]

my 2014 f250 I just purchased less than a year ago is currently in the shop for cp4 failure I am putting a dcr conversion in the shop wanted 12,585 to replace with another cp4 so the grand total for the repair is 16k I had only put 17k miles on the truck before I found metal in the fuel system warranty company fought tooth and nail but ended up paying majority of the bill no contamination was found

[@CBautofab]

Good info as always, I fill up at truck stops during my road trips but when at home I fill up at Smiths fuel stations, I've never had water in my lift pump filters and with my rewards points I sometimes save $1 off per gallon up to 35 gallons so I save some cash filling up my S&B 62 gallon fuel tank, I also treat every fuel fill up with Hot Shots EDT for my LBZ with the CP3, I also watched a cool video where the owner from S&S Diesel talked about fuel filter changes and he said its better to go to or over the recommended service intervals on fuel filter because the larger voids in the filter media get plugged with contaminants and you in turn get cleaner fuel through the smaller voids in the media, I personally have a Glow Shift fuel pressure gauge that they make for under hood application installed on my fuel feed side from my lift pump, EDGE makes a pressure sensor but its not in my budget yet, my lift pump puts out 8psi on new filters, when it reads 5psi I change my lift pump filters, I average 12K to 15K miles between filter changed and I drain my water separator filter every 5K miles when I do my oil changes, my primary fuel filter is deleted and I rely on just my lift pump filters.

[@patrickcooper1122]

I believe this will expand to all of the affected trucks, as it should, iregardless if yours has not exploded yet or whom you bought it from. Such pure chicanery!!! I purchased my 2011 two years ago from a private owner. I have not had any issues. I did install the air dog pump and it only has 64k miles, so hopefully I am good, but it sure would be nice to have the bonus cash to perform the cp3 conversion!!

I guess I'm "lucky" with a 2008 GMC LMM. 1 time when traveling out of state with a new filter with very few miles, i got fuel from a truck stop and after just 20 or so gallons consumed I got the replace fuel filter message. I had another filter with me and replaced the other one, so for many years after I only get fuel at an Exxon in South Hill, VA (near interstate 85) with NO other fuel issues. I put fuel treatment every fill up and change the fuel filter once a year because the truck only runs 3000 to 5000 miles/year.

What does that mean exactly? I bought my 2015 LML truck in 2019 from a used car lot in California. I have a feeling that if you didn’t buy it brand brand new or used from a GM dealer your SOL your thoughts? I’ll be submitting a claim next week when I get my old credit card statement showing I paid for my CP three pump. my only issue I have is that I did this project when my truck was at the GMC dealer getting a new turbo under warranty. They pulled the cab. I spoke with the tech and made him a deal on the side that if he could throw in my CP3 pump along with a PPE exhaust system and downpipe.

You talked about water and diesel fuel in years past you had water and diesel fuel and kerosene because in the pipeline system, they used to put 1000 gallons of water when they were pumping diesel fuel and kerosene kerosene and diesel from mixing when it got to the loading racks They were to let the tank sit for 24 hours and all the water settle to the bottom and they drain the water out the bottom of the tank they don’t use nitrogen between the kerosene and the diesel when they’re pumping it and grace and peace

[@victorlindquist5154]

I own a 2015 LML and a 2021 L5P and live in Maine, so I don't qualify. I am interested in the conversion kit.

[@paulprater2631]

2013 bought new not getting any money here live in va I put 2cycle outboard oil tcw3

[@peteygonemadarts4765]

Makes sense that this is an issue with drivetrain when a Diesel engine is involved . First Diesel is probably towing heavier loads . Even if not the cause is still the same . Diesel is a much higher torque creator . It also runs much lower rpms across gears , except top gear ( Diesel usually takes more rpm to maintain highway speed ) . All these factors into how the same transmission is used with Diesel compared to Gas . If geared for fuel economy that adds even more stress to a Diesel driven transmission compared to gas . Because of torque the diesel puts to much pressure on valves with low rpm at lower speeds which rips on transmission. HIGH TORQUE , LOW RPM AND AUTOMATIC TRANSMISSIONS just don't mix well .

Should be all 50 states. My grandson has a 15 3500 but guess he`s not covered because we are in Missouri.

[@David-yy7lb]

When i go out of town i always get fuel at a truck stop because they constantly have fresh diesel being delivered. Here locally at my neighborhood gas station i get my fuel at the local BP where they have diesel fuel delivered on a weekly basis because dump trucks box trucks and bobtail commercial trucks gets fuel there everyday day....I never go to a mom and pops gas station because that fuel in the tanks may possibly have water in them from moisture being collected

[@SummitAggregates]

I SPENT $10,200 LAST AUGUST WITH LARAMIE GM on a 16 LML...the link makes it sound like all trucks that had failures will eventually be covered, even if they're not covered by the initial class action settlement...at least by my reading.

[@joesnyder7128]

I haven't kept up with the newer duramax motors, did they continue to use the cp4 on the newer motors, does you '19 truck have the cp4 on it or did they go back to the cp3?

[@TruckMaster]

No they use a different pump now but it’s way better

[@dwarfzerker8456]

I bought mine 2016 lml new in kansas but truck was drivin 330ish miles from a different location dealership fer my dealer to get me the truck now at 335k miles and only issue i had was the egr over pass tube blowin up in july of 2018 and turbo been sluggish on the throttle in 2022 to today with vanes stickin and highway speeds would go in limp mode and think my fass lift pump with cat filters in 2021 is whats savin my cp4 so far but still want to swap cp4 to cp3

[@Cole-q2h]

That is weird. I don’t recall powerstrokes have cp4 failures like the LMLs. What is going on?

[@obs4life228]

Congrats for you diesel folks I just want a new transmission that shifts perfect in my 2014 sierra. If I have to pay 6300 for another trans I’ll set the sob on fire

[@grantensrud9185]

I wonder how Ford got around this. 2011 to present 6.7 uses the CP-4. What did Ford do differently, or are the 6.7s suffering from the same failures, and if so, where is the lawsuit against Ford???

[@owenpotts9697]

Ford definitely experiences cp4 failures, good question

[@TruckMaster]

I did a video on replacing the 6.7 CP4 with a DCR kit and it made a world of difference

[@timw8228]

My understanding Ford has fewer failures. I have a 2015 F250. After my LML took a dump I had a CP4 disaster kit put on my F250 and I use a diesel lube additive. Ford also has an in tank fuel pump also. LML did not have that.

[@grantensrud9185]

Maybe GM and Ford need to take up a lawsuit against Bosch? I mean, who is liable to who???

[@timw8228]

@@grantensrud9185 Why? Bosch designed that pump for Europe which has more sulphur in the fuel = more lubricant. US has low sulphur = less lubricant. I don't disagree it was a poor design but they should have put 2 and 2 together to know that low sulphur fuel would possibly cause issues. When they started to fail GM asked the dealer to send them the failed pumps. Oh they knew what was going on with the failures and why. They chose to ignore it. It's all in the court case evidence.

[@ToddChampion-iw3zm]

I’ve got 270k on a CP4 in a Ford. Gives me anxiety everyday

[@tonysims6858]

I do not qualify. I own a 2018 L5P GMC 3500 HD. I have replaced all the injectors and all the glow plugs. I'm currently at 163k miles on my truck.

[@EZY-rp4gx]

I got a 08 LMM I’m currently with an “engine power reduced” problem , any tips on the issue ? Thanks

[@justinvilottxxx]

My truck qualifies . We’ll see “The VIN you entered relates to a Class Vehicle. You are included in the Class if you purchased a Class Vehicle from a GM-authorized dealership in California, Florida, Illinois, lowa, New York, Pennsylvania, or Texas from March 1, 2010 through September 13, 2024.”

[@TruckMaster]

See if you qualify for a LML settlement secure.gmfuelpumplitigation.com/session-expired

[@louiscontreras8271]

Question I bought my 2015 used in 2019 still under factory warranty and converted to cp 3 with lift pump I’m I covered

[@jennyrickner7607]

The pump in my LMM failed at 120k miles.

[@MrCGilmore]

Mr.Truck Master...... Thanks For A Great Update And Info.....Do You Have Any Info On This Topic For Us Canadian Duramax Owners Or Hear Any Talks About Us In the North....I own A 2012 2500HD Serria with 155,000 Kms On It, My 6th Child LOL.... Cheers

[@code10garage94]

Ok so in a previous video you posted about factory fuel filter delete when adding a lift pump, is it still a good idea to delete it or leave it on as you suggested in this video?…Aloha🤙🏽

[@TruckMaster]

Yes definitely just not on a LML

[@bryanray-dol]

They accidentally put dpf and egr in my LMM too.

[@normannersten4711]

Mine is a 2015 chevy silverado durmac diesel but in Idaho

[@Jlopezusmc02-04]

What about cpx? Is that a good alternative

[@JonOffgrid]

Cool 😎 👍 videos but diesels are too expensive for me Chevrolet LS for nice too

[@TruckMaster]

I agree

[@TimMay-o8d]

I got a 2012 with c4 pump what should I do

[@TruckMaster]

Watch the video I explain everything thanks for the comment 👍

[@timw8228]

After going thru my failure I'd recommend replacing ASAP. When it fails you can also figure on it sitting until someone can repair it. Mine sat at a shop I used for almost 2 weeks. I called another shop. Same thing there. Shops seem to be stretched thin on hiring mechanics because they can't find them. Everyone wants to be a CEO or lawyer.

[@michaelharhen]

Im curious if having my EGR deleted, if that would void it somehow.

[@harlangrant1907]

I just had the cp4 pump go out on my 15 GMC don't qualify for the lawsuit live in Wisconsin I got lucky no metal in it I was told that because of Wisconsin running baio diesel it doesn't qualify

[@Freedomfreak]

What BS! Every state should be in this!!!

[@timkirchgessner763]

2015 gmc bought in Colorado. I'm done

[@CombatVet-lr8zy]

I do qualify but sold my truck a couple years back, so probably will not bother with the headache for 400 to 800 dollars.
