General Motors has issued a new Customer Satisfaction Program (CSP) for select units of the Chevy Silverado 1500, GMC Sierra 1500 and GMC Yukon equipped with the 3.0L Duramax turbodiesel engine.
According to The General, affected vehicles may have a condition where the overhead camshaft ladder assembly was incorrectly built, and subsequently installed into the Duramax turbodiesel engine. Dealers are to replace the entire engine assembly.
An important distinction to note that this is only a Customer Service Program, and hasn’t been labeled as a Service Bulletin or Recall.
Tagged with CSP number N232395830, this program only affects the 2023 model years of the aforementioned models. Notably, this means that both the 3.0L I6 LM2 (first-gen 3.0L Duramax) and 3.0L I6 LZ0 (second-gen 3.0L Duramax) are impacted, as the 2023 Yukon is equipped with the former, while the 2023 Silverado 1500 and 2023 Sierra 1500 feature the latter.
For further clarity, the LM2 was available for the 2019-2022 Chevy Silverado 1500 and GMC Sierra 1500, and was replaced by the LZ0 for the 2023 model year. Meanwhile, the Yukon has only been available with the LM2 thus far, but is expected to receive the LZ0 for the upcoming 2024 model year in conjunction with its mid-cycle refresh. Of course, the Chevy Tahoe, Chevy Suburban and Cadillac Escalade are also expected to feature the second-gen Duramax with the revision, but aren’t included in this CSP.
It’s worth noting that this CSP only affects 14 vehicles in total.
As a reminder, the 3.0L I6 LM2 turbodiesel Duramax was introduced for the 2019 model year of the Silverado 1500 and Sierra 1500, and develops 277 horsepower and 460 pound-feet of torque. Meanwhile, the 3.0L I6 LZ0 turbodiesel Duramax was released for the 2023 model year for GM’s full-size pickup trucks, and produces 305 horsepower and 495 pound-feet of torque.

If they know only 14 trucks are effected then they know which ones and can easily track them down. So just notify the owners and give them the new engines. Pretty simply stuff, and if the owner balks, buy back the truck. Easy peasy.
Im a car dealer in Texas and I’m also fixing two handful of Chevy trucks a month from the torque converter problems.
Which ones?
It’s only 14 total trucks…… I do hope my truck is not one? We do have a love affair for are Chevrolet Trucks…. Stop being a Cry Baby ! Nothing is built in heaven by Angels or Saints>>>>>>
I’m one of those impacted trucks and my small town dealer has repaired three trucks now under this CSP and a sister dealership 1 hour away has now done four. Find it hard to believe there are 14 trucks in total effected, when the two dealers I know have now repaired 7 between them. @GM – what aren’t you telling us?
A camshaft made incorrectly is what makes gm a joke to toyota owners when in the history of toyota has a camshaft been made wrong missed all quality control processes and went into vehicles NEVER THATS WHEN. People shouldn’t accept this garbage. Gm quality control doesn’t exist anymore I don’t think it ever did
How many GM products have you owned?
TRy Customer service 1st, number is in your owner manual. The problem is before the warranty was up. No Help, alot of attorneys in the yellow pages that will help. There paid cases with your problem!
Believe Me there is a fix ! IN California ?
1955-1969 15 Chevrolets
1970 to present 30 Chevrolets
Current Chevrolet 2023 !500 Crew Cab LZO High Country with 22 in wheels Multiflex gate… Hard truck to find????????
Toyota has more recalled vehicles than anybody. They had a similar camshaft recall on 2007 tundras. Why worry about actual facts though. Maybe toyota should start making dealerships without service departments since they’re perfect.
Unfortunately at some point you have to look at that Toyota !! Nuff said !!
Yea ToyToys just kill you with metal air bags like a grenade or how about the gas pedal sticking. So what QC are you talking about????????.
I’m a car dealer and fix them so I won’t pass on the problem
I guess the Toyota guy forget about the rusted frames and the spare tire falling out and ripping out the brake lines.
Tell me about it. I bought my son a Toyota Tacoma this past year and noticed a small hole around where frame bends upwards in front of rear tire on both sides. I’m a metal fabricator and so I go looking around a LOT damn closer and I noticed blistering in the coating that someone sprayed on the frame. I pecked around on frame with lil ball peen hammer and the whole d@mn frame from front of bed back bout fell the hell apart. I got on net and found out bout their frame garbage and about $hit myself. My son is driving my GMC Sierra until I figure out what to do with this overpriced piece of $hit Toyota. I have 12 Nova’s 2-67’s and the rest between 68-72..and the clips on them are still looking d@mn good to be that old..I’ll have a telescope ran up my @ss before I ever buy another Toyota..G.M. FOREVER!!!
Nice made up story there.
I have a GMC 3500 and it has Def fluid problems. I have replaced 3 so far and they no it’s a problem but won’t do anything about it. It is not in warranty anymore passed by 550 miles and now I have to pay 1400.00 to fix it.
Def fluid problems falls under emission warranty, which, iirc, is 8-10 years 150,000 miles. Of course, my dealer tried to charge me for a Def Tank and Def heater replacement at 53,000 miles, I told them to think again. Dealers double-dip by charging the customer and GM warranty claim.
I just bought a new 2023 Crew cab 3.0 liter this past week. Do they have Vin Numbers for the affected units?
I can’t believe someone thinks it is OK to defend one brand against defects. If I’m not mistaken, Toyota, Avalon’s and or Camry‘s were affected, but definitively, I know that certain models of Lexus were affected and due to the wiring harness pin assembly, which is a very intricate assembly, the Excelerator pedal would get stuck electronically speaking, and you could not turn the car off and it would continue to gain speed, and there was very little you could do, and a handful of people died very horrible deaths because of it and if you want to get technical, especially relating to diesel motors, Toyota put some form of a Cummins in a titan and they…. just like Chevrolet is doing right now, Required some zero something weight oil and due to engine failures and I believe it’s the main crankshaft bearings or whatever, I’m not positive… but regardless, they had to change the specs on the weight of oil that needed to be used and they also had other problems and that motor is not highly revered by anyone and they chose to allow it to be put in their vehicles just as Chevrolet is allowing something faulty to be put in their vehicles, so do not throw rocks when you live in a glass house and having a 4.6 L motor that has never averaged anywhere in the ballpark of decent fuel mileage and their five point whatever liter V8 has also never gotten any where close to decent fuel mileage either, I don’t think that Toyota connoisseur‘s really need to be throwing rocks but in truth, I don’t believe anybody should throw rocks. I think we should just be nice to one another and offer advice and counsel without being judgmental about it, but that is simply my opinion to the person making references to Toyota versus Chevrolet…
I wish Chevrolet would issue a recall for the faulty cp4 fuel pump in my 2012 Silverado 2500hd 6.6 duramax. LML, BEFORE it self implodes and I suffer the financial consequences! No joke…
It’s not the CP4 that’s the issue, it’s diesel fuel chemistry that robs the CP4 of lubrication. Run diesel fuel conditioner at every fill-up.
Recalls are good. They have identified a problem and are taking care of it. It’s the things that should be recalled and are not is what is most concerning.
They need to recall other vehicles as well, I have a 2015 yukon that is the biggest piece of junk I have ever owned and will never own another!!
Customer satisfaction should be a 2024 new truck.
I love my 2021 Chevy Silverado 1500 High Country Duramax diesel! Husband had 1997 GMC Sierra that drove up to almost 350000 miles.My son currently drives a 2005 Chevy Silverado 1500 & still runs like a beast with close to 300,000 miles.
Put the 3.0 L Duramax in a GMC Savana 2500 van and I’d buy it in a heartbeat.
This engine has been a disappointment from the beginning. I had money in hand ready to buy one until I saw the design. Looks like German millennial engineering. 1200$ internal oil belt, timing chains in the back hard and very expensive to work on.
I have a 2021 LTZ with three 3.0 and LOVE IT! I get 31 mpg on the road doing 75 mph. 40ish mpg at 55
I would fight someone if they tried taking my truck! No complaints yet, of course all vehicles are going to give you trouble at someone. I seen a tee shirt at a NASCAR race and it said” if it has tits or tires it’s going tho give you trouble eventually”. 😆
So……. I have a 2020 Silverado with the 3L Duramax does this mean that there is an issue with mine aswell. I read down a little further and it said that the 2019-2022 were also built with the same motor as the affected 2023 models.
Exactly. Zero quality control. I have a 2017 Escalade with the 6.2. Just ticked 55k miles…one month to the DAY out of power train warranty and tap tap tap…lost a lifter and a bent pushrod.
Opened a case with GM…..oh we will try and get you some reward points…what?!
Just bought a brand new zr2 as well… ridiculous.
I just purchased a 2023 GMC AT4, with the 3.0. So far I love it. I am very cautious about new technology. To protect myself or my pocket book, I have warranty that goes out to 100,000 and before it ends I will purchase another one most likeley. Nothing last for ever, and depending on driving habits or the lack there of, will most likely affect how long your vehicle and its components will last. You have to remember,this is not 1967 when there were no on board computers, and just about anyone could repair an engine when it failed. In todays world not so much. If you want to protect your investment, keep a warranty on it, or get ready to come out of pocket for a major repair. Its that simple. Nothing more, nothing less.
So GM will replace the diesel however won’t do anything for the trash 8 speed transmissions and lifter issues in their 6.2 V8s?
Doesn’t make sense.
It’s going to be more than 14 engines. Mine started struggling in less than 3k miles.
I just bought a 23 gmc evolution with duramax 3.0. I’ve got about 830 miles had it for 2 months is my truck under this category for the problem? The way they word $hit is ridiculous get to the point of the year vehicles that could have the problem can anyone give me some more information on this ? Thanks in advance! I got a better drive train warranty doubled from 3yr 36k to 7yr 70k just for drive train plus the 100k for the rest of it.
We purchased the truck from *** in — TX on 8/30/2023 with 13 miles on it. My wife drove it home and a day later I was driving it to my doctor’s appointment in Alvin TX. On hwy 35 a warning light came on “Low oil pressure turn off engine!” (stopped at 5675 TX- 35 to be exact) I was in busy traffic and next thing I know the truck just dies. It was 104 degrees outside here on 9/1/2023 and I’m stuck on the side of a busy hwy with no AC. I have to wait an hour for someone to come rescue me. In the meantime I call the Orthopedic doctor and tell them what happened. I have 2 broken bones in my back that I am still suffering from.
The truck gets towed to the nearest Chevy dealer which is *** in Alvin. The first thing they find is that the fuse box has melted. I told them about the oil pressure warning but they dismissed me as someone that doesn’t know what they are talking about. A few days later they say the wiring harness is also melted. A couple of weeks later they say the starter needs to be replaced. A month later they say the engine is actually seized and they have ordered a new one from GM. Ron Carter said that they have no loaner trucks… We need a truck.
I call *** and tell them about the situation on 9/1 but they say that they can’t do anything without the truck. I asked for a different truck and they basically said I bought it, it’s my problem now. That really upset me so I looked into the Texas Lemon Law and basically we had to wait 30 days.
From the second week out we have been dealing with GM’s customer service out of Detroit and they told us that the Lemon Law does not apply to them because they are not in Texas. That really got my goat so I decided to go after them because their faulty product put my life in danger. I am injured from a previous incident, under a doctor’s care, and was at risk of a heat stroke due to their product’s failure at 125 mile on the odometer. What if I had injured my back even more trying to steer the dead vehicle clear from the road? Who’s to say that I didn’t”
Well that’s the short of it. GM is all over the place with excuses. One phone call they’re going to buy it back. Another phone call they can’t do anything because they’ve ordered a new engine. We’ve been recording all the phone calls with time and dates.
I have many questions. Did GM put an older engine in this 2023 truck that had the known issue from the Oil Belt? Was it indeed the oil belt breaking that caused the truck to fail and is that in itself enough to find GM liable for my breakdown?
