GM Authority has learned that GM intends to buy back certain Chevy Silverado HD and GMC Sierra HD units back from customers due to apparent quality issues with the 6.6L L5P V8 Duramax turbo-diesel engine.
The affected vehicles, which have been sold to both retail and fleet customers, will be repurchased by the Detroit-based automaker in an upcoming Dealer Order Submission Process on April 21st. This includes vehicles that have already been delivered to customers. It’s currently unclear what kind of quality issues affected the Duramax turbo-diesel engines in these trucks.
6.6L L5P Duramax Turbo-diesel V8
While GM has agreed to replace affected trucks, the replacement vehicles will be subject to certain feature constraints due to the semiconductor chip shortage. There are currently multiple feature constraints on the Silverado HD and Sierra HD, limiting the availably of heated and ventilated front seats, heated outboard rear seats, heated steering wheel and front and rear park assist. Due to these supply constraints, it may not be possible for GM to exactly match the replacement trucks with the ones being repurchased. These feature constraints vary from trim to trim, however, so some units may be less affected than others.
The 6.6L L5P V8 Duramax engine is produced at the DMax Ltd. engine assembly plant in Moraine, Ohio. The facility has produced more than two million Duramax diesel engines since operations began in 2000 and began producing the L5P-generation engine in 2016 for the 2017 model year Silverado HD and Sierra HD. DMax Inc. is a joint venture company between GM and Isuzu Diesel Services of America, Inc., with GM claiming a 60 percent stake and Isuzu owning the remaining 40 percent.
The current 6.6L L5P V8 Duramax engine produces 445 horsepower and 910 pound-feet of torque in the 2022 model year Silverado HD and Sierra HD. This turbocharged diesel V8 enables a maximum towing capacity of as much as 36,000 pounds in properly equipped Silverado 3500HD and Sierra 3500HD models.

It’s bound to be a small number of largely very new and unsold vehicles, otherwise they’d swap the engine or engineer a countermeasure. (See Hyundai/Kia’s piston rings and Ford Ecoboost head gaskets)
Yeah why can’t they just swap the engine? That would be the smarter move.
Because how’s the customer gonna feel about their brand new truck getting the cab pulled and engine swapped lol. They are saving themselves the headache
Actually Holden’s the right answer! They should ship them over to Australia for conversion to RHD, they rip the cab apart anyway, doesn’t make a difference if they put it back together with a new engine.
They can easily sell it, seems a little strange to buy them back.
MFR’s buy them back due to lemon laws and makes the consumer whole again.
How do I find out if my truck is one of them?
Inside scoop is that most if not all of those are at the factory and weren’t released to dealers. But swapping motors makes more sense for any effected units that may have made it to customer, especially where customers have added bodies and other customization. Is GM going to pay to swap those things?
They would generally buyback the entire vehicle including modifications. Reasons include the fact the vehicle may be inoperable or unusable in the future without the mods (fuel tank relocates, things welded to frame), and it would cause problems with financing/leasing where the collateral is based on the value of a single working vehicle.
Anybody know where we going to find if my truck is part of the repurchase program?
I have the same question?
Anyone know how to find out?
My 2020 2500hd as been at the dealership for a month now over a recall on Def Tank that is apparently back order..
I had the DEF tank issue as well.
Hit me up for the solution
I have the same issue. Been without truck for 2 months. Please let me know the solution.
i have a 2020 high country second def tank vehicle at the dealership gm put me in a rental with no idea when i will get let them buy it back
What was the def tank issue and how did you fix it
Mark:
Appears to be a vendor supply chain issue. Around 90% of the parts on a motor vehicle are vendor sourced.
I had 2012 duramax 3500 Hd at 84000 miles I had many issues with fuel sensors then injectors then they had to replace the injector pump so I traded it in for 2017 3500 high country both brand new now at 86000 it’s in the shop as we speak getting three new injectors and sensors as much as theses trucks cost they need to buy them back .
My new truck 3500HD has been at the dealership since the 2nd week of February waiting for a Def tank
Facing the same DEF tank/wiring harness issue on my 2020 2500hd now on national back order… Is there a work around to enable truck use while waiting,,,, presently crippled with speed limitation
Mine won’t start at all. Has been in the shop well over a month
Could you let me know how it worked out. Dealing with them now for a DEF issue.
there is no way to check. they will contact you. usually via mail. so don’t call them, they’ll call you. they may use the dealer you purchased from to contact you.
Buford:
The way I look at this it has to be a total drive train design / matching issue. Notice it’s unique to the HD models. More performance matching for hauling. Engines are randomly pulled and used from the assembly line. Coupled with an Allison automatic transmission set for HD application, hooked to a heavier duty driveline or engineering term, propeller shaft.
There is a major mismatch concern in these components maybe even leading to stoutness of the differential.
Anyway to me it is a major component mismatch issue. Not a manufacturing issue. To me, I bet it relates to torque production and stress, either under or over.
I know that in Caterpillar diesels and transmissions there is a ” black box ” control unit that talks back and forth between the engine fuel delivery, and transmission gear selection to provide proper torque and speed for the load in various applications.
This control unit was originally developed by Woodward Governor Co. of Fort Collins, Colorado.
Very sad that these new HD trucks are going to be crushed.
worked at Gm plant for 30 years, no engines are not randomly pulled and used from the assembly line. Engine is matched and placed in sequence the moment the order is received at the plant. The engine and trans all have barcodes which are matched and recorded. There is no random engine or trans installs. Everything is matched and married to that vin. The engines are defective, that’s all. They just don’t have the engines to spare on warranty. Every new engine made goes into a new production vehicle right now, there are no extras!
I’m a technician and for years I’ve got engines pulled from the assembly line for replacement in customer vehicles. 41 years under my belt.
Carl Ohsowski:
I’m with you. Pull the component from the assembly line and do an R & I on the affected vehicle.
It’s totally insane to scrap the entire vehicle as Buford claims.
I think there is something amiss with the galleries in the aluminum engine heads when the engine is subject to HD applications.
The engine head is the most complex cast part in a vehicle. I am not a big fan of aluminum castings. Gray iron is so much better for heat sink. Most people do not understand what heat sink is in a diesel engine. Many people do not know how to drive a diesel engine.
My mother, RIP, thought that vehicle operation consisted of getting into the driver’s seat, lighting a cigarette, put the key in the ignition, start the car, shift into desired direction and go.
We will note this issue is unique to the HD models which are subject to higher loadings.
Your dealer has VINs they’ve sold where this would apply.
I got. 2017 Chevrolet 2500 High Country diesel Duramax with Allison wonder if that’s one of them
I had to get an injector change already to
Sure glad I decided to go with the Cummins after reading this. I drove all models in 2021 and though I preferred the Allison transmission as I have a 2002 Chevy 2500 8.1L big block Allison combo also. The Dodge Ram 2500 checked all of the boxes and now after owning one for a year / 36,000 miles in, it’s by far the best truck I’ve ever owned coming from a lifelong Chevy fanatic.
too expensive, if it was cheap to do, then thats what the customers would get. All these trucks will be destroyed and written off.
Buford: I don’t think GM will crush the returns. GM will make the fix and then list them with Richie Brothers auctions, or insurance salvage pool auctions.
no they won’t, worked at GM for 30 years. They will be destroyed. If they are repaired they are used, no warranty. GM is not in the business of selling used vehicles.
I work there where it’s built! Back ordered parts keeping parts unavailable to dealers to do just an engine swap
Mike do you have any inside info as to what is actually going on with the engines and or exactly which ones may be bought back by Gm? I have a 2022 Duramax Hd with 4k miles and no known issues yet. Thanks!
2022 Ford F-350 king Ranch , ordered it, 8 weeks later in hand , truck has 11K miles on it , runs flawless , and it does not have cheap unfinished plastics , stupid looking door mount mirrors, good for a year tires, or a blown plastic interior with a car like dash. EL CHEAPO motors INC = GM trucks
Yeh, Ford got a major recall for ALL super duds for towing problems to electrical problems too!!
It was a software update , took 6 minutes in service lane and back out of there , it did not have a bad motor and quality issues like General Junk Motors with the fake Allison
You mean like the Ford 6.0 what a piece of crap spend another 4 grand to make it bulletproof lol
You can’t make a Ford 6.0 bullet proof. Friend spent 6k doing his and it just cracked the heads again.
It’s interesting that US automakers realized they know squat about diesels and went to diesel makers for their diesel engines after GM’s 350 miserable failure. Ford went to International for the 6.9 and Caterpillar for the 3208. Chrysler went to Cummins. GM went to Isuzu.
Ford also went to a Brazalian diesel maker.
Ford decided to go it alone and struggled with the 6.0.
Cummins and Caterpillar are the best go to outfits for diesel know how.
However, Caterpillar in not wanting to invest in Tier 4 final, and sadly producing two dogs, the C 13 and C15, sadly abandoned on highway diesels leaving the playing field open to Cummins, Detroit Diesel and Scania.
Cummins is rocking and Detroit Diesel has expanded their Outer Drive East plant in Detroit.
Eaton is in Fat City with their Roadranger on highway truck transmissions.
This is a very fascinating, very competitive and interesting business.
A Happy Easter to all.
Thanks for the info. I really had never thought of the different manufacturers in this light. Always loved Chevrolets, probably why I just love the diesel that’s in it….. but truth be told…..
My 2017 HD I bought new has been riddled with various failures. I’m planning to sell her. F#%&!#@ shame, but I’ve bought 5 new Chevys in my life so far.
NEVER had problems like this ones got.
Nice review but Ford went alone for the 6.7 Scorpion engine from 2011 up. It is the only manufacturer building it’s own diesel powerplant in the medium duty truck as of now.
Ya but ford is still using the CP4 injection pump, with the 6.7, have fun when it generates, taking your Ford out for a while.
Well, you’re lucky you didn’t buy 2003-2006 6.0 Powerstroke Diesel engines in the F250 HD & Superduty Fords. The worst of the worst and you wouldn’t have gotten a buy back offer! You were stuck with this junker engine!!
Well actually I just skipped them altogether, both 6.0 AND 6.4 after having owned three 7.3’s! I bought a 2017 6.7 Lariat and very glad I did!
Sell the defective trucks to the Chinamen!
How stupid! Congratulations moran

“we can’t let these thoughtless morons get away with mindless vandalism every weekend”
“Almost” everyone of these trucks are sold before they the lot. Weeks, if not months, before.
Cheap hardly efficient virtually runs on luck every time.
Gotta mechanic coming?
Found On Road Dead. Flipped Over Reservation Decorations.
I thought people only bought GM products because they know for certain the vehicles are defective. Cutting corners and skimping on quality earns management their bonuses, and making cars that spontaneously turn off and Kill their drivers – well that’s just icing on GM’s cake.
I work for a GM dealer in Canada, and the issue that affects these trucks is Hydro Lock. I only learnt late yesterday afternoon that one of the High Country trucks 3500 is being purchased back and I will get a replacement unit from GM. The issue seems to be very serious to the point that they want the engine swap done at the Flint assembly.
i heard the same thing ,heat treat issues on the block at causing cylinder head to block mating surface warpage, causing hydro lock. I believe this issue is also on certain L5d engines for medium duty trucks.
Bill:
You state, “Heat treat issues on engine block “, I never heard of either an aluminum or gray iron engine block being heat treated. ??? The 6.6 is an aluminum block. Perhaps the Mazak machining center for the aluminum blocks had a programming issue.
BTW: Mazak is superb in their turning and machining centers. Always enjoy the Mazak machine tool display at SEMA.
My mother was in quality control at Clevite on St. Clair Avenue in Cleveland, Ohio. She hounded the millwrights to adjust the bearing shaping tools when they got out of whack by just a few ten thousanths. The millwrights hated her, but Clevite made the best bushings and engine bearings in the world in their heyday.
An engine is like a Swiss watch. Keep her clean and treat her well.
The 6.6 D-Max does NOT have an aluminum block. The 3.0 in half-ton trucks does. The 6.6 is iron block with aluminum heads.
I don’t have an engine issue but I have a transmission issue. I would like for them to buy back my 2018 GMC Sierra Denali. 28000 MI and they tell me the transmission is fine the way it is. I would say that the transmission is just as important as the engine.
So this is the only comment that actually addresses the article. Does anyone have any info from any other source beside GMAuthority?
I looked on GM, Chevy and GMC sites for news or service bulletins and I’m finding nothing. The NHTSA site has nothing.
Is this just click bait?
I’m sorry but GM has NEVER sold a diesel pick up truck that worked, ever.
Idiotic statement. I had 2008 Duramax; 125k without any issues. Guy I sold it too is still trucking at 250k
I was a builder for a decade routinely saw various vintages of them with 300-400k to include some whose lot in life was towing 10k+ in equipment daily.
Well you definitely are sorry. That’s for sure
I ordered a 3500 single axle two months ago. I bet this delays my July delivery expectation date
Very vague article/information unfortunately. This can cover what 5 or 6 years worth of truck engines, or hell it could be one bad batch from one single shift at the engine plant
7000 engines! Half made it to customers! Roush Automotive swapping the rest out for GM
william wahl I hope you bought a FORD 6.0 diesel I’ve never had problems with gm diesel and now amdfighting a def problem on my ram What color Prius do drive
Obviously as demonstrated by your comment, you don’t need to be literate to purchase a gm diesel.
Which trucks will be replaced? Where can I find out if my truck is one to be replaced??
i heard the same thing ,heat treat issues on the block at causing cylinder head to block mating surface warpage, causing hydro lock. I believe this issue is also on certain L5d engines for medium duty trucks. I believe its a relatively low number of 2022 engines affected.
They buy them back so it doesn’t go thru the court system and they become lemon law titles and GM will lose their ass better to repurchase them and repair the problem then sell them as repaired and someone buying them will sign papers that they know this making it a win win for GM they will be re-sold to GM dealers only across the country and GM will take a lose on taxes! So no lose!
repair them? Not a chance every truck bought back will be crushed. Worked at Gm for 30 years, its all a right off for them.
Uh guess we’re getting a new 2500 cause my trucks been in the shop for 45 days. They say can’t find the part for the turbo diesel.
same here!
Is this an issue with the Def tank? Truck in limp mode? Production on those tanks are causing issues. GM is slowly getting them shipped to the dealers starting last week.
If there were alot of them, they would deny it.
i have a recall letter currently over injector issues they cant repair 2019 GMC denali duramax. GM has a ton of problems folks and all they do is turn out new paint colors , and more cheap sh!t.
Little will be known because of “corporate secret policies. All companies, especially manufacturers, will only release information through marketing channels one of which is TSB’s. Manufacture defects or engineering design errors is usually tightly guarded. The manufacture is only tied to the warranty statements.
We are on our third chevy 4dr gas, 1989 old gray 480+ on a single rebuild engine still pulling gooseneck, 2002 duramax 410 miles still running drive everyday, 2020 duramax 54000, no problems with it either..we are truly chevy fans. At least they are owning the error and fixing it.
I’m running a 2003 GMC 2500HD that bought brand new….only issue I have…people trying to steal my truck.
Ford has never built a reliable diesel. Duramax>Powerchoke
Strange things are happening here. Remember the suspension of 6.6 production for a couple of months last year.
you believe this buy back is related to the two month suspension? please explain. Very curios because I own a new 2022 Duramax Hd with 4k miles and no known engine problems, thankfully. Just wanting to learn more about this buy back. I contacted my salesman a day after this news broke and he has heard nothing of this yet.
Everyone needs to actually read the article on this. It clearly says ” will be repurchased by the Detroit-based automaker in an upcoming Dealer Order Submission Process on April 21st.” So no real information until then.
The 6.6 D-Max was the last bullet-proof drive train component GM had. It’s a shame they’ve screwed it up, too.
Considering they’ve substantially turned their back on owners with failed valve trains in AFM & DFM vehicles, failed 8L90 automatics, and 3.0 diesels that won’t start, I cannot imagine how bad these D-Max engines have to be for GM to replace the whole truck and not just try some chicken $#!+ partial repair that may or may not keep it running until it’s out of warranty.
I would think it would make more sense to just replace the engines.
no it would just cost them more, Gm will destroy them. Replacing engines too expensive. All they end up with is a used truck that they can barely break even on.
Now I understand why they want to go all EV. Let’s go Brandon!
Buford: Very sad that GM will cube these trucks for melting into hot rolled strip steel at the steel mill.
Here’s the issue I have with all of this. Fine, it happens. They will fix it and move on but we ordered our 2500 HD Diesel in July. It was accepted and built in late November, finished first week of December and then shipped to Flint, where it’s sat since. We’ve been given no less than 8 different expected delivery dates. We heard rumor of this issue weeks ago and yet not person has reached out with confirmed information. It would be real awesome if could be given SOME sort of accurate update.
Saved a dime during production and will cost them in the long rung.
GM has always done something stupid to get there name in the news….
Get rid of Mary.
good union made
Must be a republican
What about the 2019 GMC trucks that have early engine failure???? 100 thousand miles and engine had to be replaced .
LINDA,
My 2019 Denali duramax just received a recall letter about failing injectors, and are they going to replace , NOPE they offered warantee on injectors to 150K to save cost , Mary Barryass GM junk what a mess of a company.
I wonder if they will use this to address the issue with the Valve controller on the transmission, that causes rear tires to lock up at random while driving!!
Gm will take them back then give them to the illegal immigrants that are flocking to the US.
Great more problems with GM ordered into late September built mid-December not inspected till January and sitting in Michigan ever since not even set up for Transit yet and I sold my truck after it was built and had a VIN number now I sit without a truck.
Rick
Order a Ford , youll have a vin # in a week , and a truck 7 weeks later. and all this GM crap with engines , poor communication , ect go’s away
To the guy who said that “GM has NEVER sold a truck that worked” from my personal experience with a bought new 2009 Chevrolet Silverado 2500 6.6 Duramax 4×4 extended cab with currently 179,251 miles the CEL has not came on at all nor any other MIL light for that matter since I’ve owned this daily driver from purchasing form the dealer.
Now please explain your very untrue statement.
It doesn’t matter what brand a man buys what does it how that man performs maintenance on said vehicle. Period
I’ve never understood why an article about GM on a GM page would lead to Ford or Dodge discussion, or vice-versa.
All brands have made great vehicles and have also made absolute garbage. All brands took loans from the government during the economic collapse, all brands are grossly overpriced, and aside from the Chevy Legends Group, most brands don’t really give a damn about the consumer. I don’t understand the undying pride that some people have for their brand.
Personally, I don’t care if it’s a Ford, Chevy, Toyota, Nissan, Honda, whatever, so long as it’s a quality product that does exactly what it’s supposed to do and is dependable and reliable.
I will say this, the only vehicle I’ve ever had that was just a complete pile of shit was a 2011 Chevy Impala. It had electrical issues from day one. The Stabilitrak, ABS, and Traction Control functions never worked on the vehicle. It spent virtually every second I owned it in limp mode, and eventually it was return to GM via the lemon law.
Did that change my opinion of Chevy or GM? Not really, it was disappointing but when you put out hundreds of thousands of vehicles on an assembly line, there’s bound to be a POS that slips through.
Ford did not take a hand-out.
The EPA emission mandates and Fed fuel economy mandates have loaded on highway and even off highway equipment diesel engines to strangulation.
Exhaust gas recirculation, particulate filters, high pressure common rail fuel system, UREA injection, twin turbos in some cases, low sulfer diesel fuel, black box chip controls….it’s a wonder the diesel functions.
This has nothing to do with anything defective…. they are just trying to buy back your ICE. Vehicles and then tell everyone to get something electric… why would the buy it back and not just replace it…..come on…. this is a weak attempt….
Hello
I have a 2020 GMC Denali with A 6.6 diesel, is this engine in there call back replacement?
Now I understand why they want to go all EV. Let’s go Brandon!
Just wondering about my 2020 High Country 2500HD?
I ordered a 2022 GMC 3500 AT4 in November 2021. It was delivered to transit point in Milpitas Ca 2/11/22. There it sat. They communicated with dealer it would be delivered 2/28. I sold my 2022 2500 Silverado on 2/28. No delivery. Dealer shocked. Crickets from GMC. Their 800# is a third party vendor with no access to info. It is IMPOSSIBLE to have anyone in GMC management accessible to customers. My brother’s neighbor (a GM engineer) eventually got me in touch with the CA Xone manager for GMC/Buick. She was a loss for words. HM communicates with nobody. I received a call from my dealer. No AT4 will be delivered. They offered up a Denali HD for what I paid for the AT4. (to my benefit by nearly $5K) that’s the dealer stepping up not GMC. Ultimately the Denali with its ass-ugly cheese grater grill will be delivered to me Wednesday 4/20. When I can I’ll order a 2023 AT4 3500. My dealer Dow Lewis Motors in Yuba City CA has been fantastic. Cream of the crop! Its too bad GMC Corporate customer service is so horrible. No follow thru and lies.
Hell I have a 2018 Chevrolet 3500 LTZ Duramax 6.6 and from day one the engine bock heater was recalled. Been replaced once. Shortly after that it was recalled again. Every time I ask the dealership they state there’s no replacement available. I had a long conversation with GM costumer service and they only stated the same thing “NO FIX AT THIS TIME”. My only response was “THATS NO WHAT I PAID FOR”. Still waiting! If they want to buy this thing back they can have it!
I Would Absolutely Never Buy A P.O.S. GMC Or Bowtie Diesel Or Even A P.O.S. Ford Diesel And I’m A Bonified Ford Lover! I Got A Dodge Ram 3500 With A Cummins Diesel! If It Doesn’t Say Cummins Or Caterpillar It Isn’t Worth Having Period! Ever Since Ford Quit Having International Build The Power Stroke They Have Been Junk!
caterpillar has NOT had a road engine since 2006. The Cummins in my Ram 3500 with Aisin pulls well, but when its not pulling its reserved . the OEM air bags are bad ass for picking up load. The 2022 Ford I have runs flawless day in and day out not a single problem in 9 months and 18K miles and I pull trailers all day long. The internationals were junk after the 7.3L . The 7.3 were bullet proof but underpowered.
Where can I find out what year models are they talking about and what actual issues with the engine??
AlexB
GM will never disclose particular issues they have with the 6.6 Duramax in HD trucks.
This opens the doors for product liability lawyers. And is just generally bad publicity.
David
The only issue that I have with mine after pulling my travel trailer for about 45 miles it goes into limp mode with P0087 code and fuel filter to 0% life message and fuel filter has about 80% life left. Been to two different dealers for same issue. Everything that has to do with this code has been replaced and it still does it. I’m not sure what issues they’re talking about on here and year models, mine is 2009 and I’m the second owner.
Everyone needs to actually read the article on this. It clearly says ” will be repurchased by the Detroit-based automaker in an upcoming Dealer Order Submission Process on April 21st.” So no real information until then.
Just called the dealer. They said this is B.S. Unless it comes from GM or your dealer, don’t give it any more thought. But… Again, we’re talking to a dealer. So… Who the “F” knows.
Does anybody know how to stop the GM Authority comments coming through my email? I get about 20 comments a day and would like for it to stop.
go to the last email. At the bottom there is a link to manage your subscriptions. There you can change email notifications.
I like these Ford guys criticizing gm for plastic interiors, do they close their eyes when they get into their trucks? Same idiots that fall for the stupid names that Ford gives their junk. Gunna get me a tremor with a godzilla engine with 430 gears so I can visit every gas station. Face it every manufacturer will have issues but to stand up and correct the problem says a lot unlike ford’s 6.0 anchor.
Kevin,
Sorry you can’t afford fuel for real motors, thats why you , Brandon, AOC , and Elizabeth Warren love the new 2.7L rice burner and there 330 rear they are putting in the silverado for you. You want to talk about the 6.0 Diesel, it was 15 years ago, let it go man, yet you have GM buying back trucks they built last month. One last note , even GM stated there interiors are lacking and suck . 90% Blown plastic full of compartments that don’t hold anything. I’m sure your excited and love the new sissy girl car dash in the trucks.
Mickey
I don’t have a problem affording gas but would rather spend it on my big block camaro than some godzilla that can’t pull anything of size up mountain grades without 430 rear gears and they are 340 in the Silverado which works with a diesel no matter who makes it because they do not require high rpms . At least GM is stepping up to correct the problem which Ford never did no matter if it was 15 years ago or yesterday. Interior wise I bought a truck to tow horses or a drag car and if I wanted fancy interior I would have bought a high end car. Last,according to your comments, if I wanted a a sissy girl dash I guess I should have bought one of those awesome fancy fords with the theater size screen on the dash.
yes sir , your a Broke D@#k Dreamer . I am very proud you know so much about the Ford’s . Ford out sells them all. GM has 8 brands , and Toyota kicked there a$$ this month.
GM is not stepping up, there in DAMAGE control. They don’t admit nothing. Remember the 41 people that died over a faulty Ignition switch in their cars 4 years ago.
GM has your sissy dash, looks like it belongs in a Lincoln town car or Cadillac. GM use to be great , Mary Barrya$$ has ran it in the ground and you know it. I have a 2019 Denali 2500 , the piece of sh!t has 4 recalls and I just received a letter stating the injectors are a problem but there not recalling it, so the government forced a 150K warranty on the injectors, but that go’s away when sold. Damage control.
I had a 2008 Duramax, sold it with 330,000. had computer issues, but with that fixed, it worked awesome
What issues?my ecm died Canada price $850 plus tax
Mickey mouse
Well at least I have a d!ck. Yes I do know about fords because I have a friend that is a die hard Ford fanatic ( dropped on his head at a young age) and had to Sue Ford over a pile that he was stuck with because they wouldn’t admit it was a pile. He then bought a 2022 Tremor and after 2000 miles sold it back to the dealer because it wouldn’t pull his 30 ft enclosed trailer with a drag car like the Chevy. You keep saying how cheap the interior is and it has a sissy dash have you even looked at the dash in the Ford truck now there is a plastic sissy dash that sets off alarms and has little coffee cup show up on the dash telling you to get some rest and all of that cost 10,000 more than my Chevy. You bought a Denali and I will bet it has a lift kit and big tires, little man disease, and never been off road or towed anything. Climb out of your mom’s basement and get a clue. Did Toyota fix there engine oil problems?
This was a note I got back from my dealer. I have a 2020 and its not in the list. Looks like just resent one. This is what was said if its any help.
We just had a couple of them bought back but it was before the trucks got here. They had originally put out a recall for something on them but for whatever reason decided to just buy them back. I don’t really know much more about it other than what is in that article. Luckily we didn’t have any that had already been delivered to customers.
That is correct. They sent out a spreadsheet with every VIN affected and we only had 2. I believe they are all ones that were recently built.
What creditable source did you get this report from? I contacted the CEO’s office and GM is denying it.
Thanks!
Would my 2017 Chevy Z-71 1ton duramax be involved in this recall ? I’ve had def problems, engine problems, an engine fire and it has 100,000 miles on it. Out of warranty. Everything has cost me out of pocket.
Well I got a 2021 3500 hd 4×4 high country and its awesome. I pull upwards 40k lbs and I just put 95k miles and it’s still works fine . I’m certain that it outperformed better than any dodge or ford trans temp never exceed 170 degrees going up the colorado mountains. Anyways if anyone has any info let me know I’ll take the 22 with new dash.
I hope this is all “fake news”. I have a 2017 Silverado 3500 Duramax with 61,000 miles. About 24,000 miles has pulled 18,000 pounds. No issues. Only problem I have is dealer jerking me around on a recall on engine block heater. A dealer in Texas disabled it (as recall requires) and couldn’t get a replacement in Texas. They were all shipped to the north. Now my dealer in Wisconsin is jerking me around saying recall is closed. Its not closed and dealer is telling me they aren’t getting a response for a fix to correct coding on the recall. A dealer that really cared about customer service would fix the problem and then take it up with GM. You don’t put the customer in the middle.
Who do we contact regarding this buy back. I have a 2017 Duramax that has been nothing but problems. Check engine light is on more than its off!
Jesus thanks for the fuel filter info, oem, my 2021 2500hd is about due for a filter change and I will definitely get a oem filter. If I am not pulling horses it is a drag car and I love the way it tows.
Sooo…..anybody hear anything else a out this??
I purchased a 2020 GMC 2500HD Denali seeing what people are going through with injector problems and DEF tank issues, how long before I start to have problems with the same issues. I change my fuel filter every other oil change and try to buy my fuel from the same place every time keeping away from bio fuel hoping this will save my injectors. I worked at a Caterpillar Dealership and problems with low power and injector issues was the cause of the fuel filters, Bio fuel and contaminated fuel most of the time.
Hi everyone I found the issue to injector 8 out of range, the aftermarket fuel filters have different fuel flow there for starving injection pump . Dealership charged me 350$ for a good mass airflow sensors. And just clears the code.
As soon as I got home code came up again.with all do respect they can “”””””””””” .
Just put oem filters and put a white can seafood treatment and the monster is alive
2021 Chevy 3500 4×4 high country 98256miles
Pulling a big Tex 40ft 25gn hd average combined weight 37,000 lbs . Yes all miles is pulling miles from coast to coast
my 2021 denali hd has been in the shop for 2 months waiting for a turbo. idk what they going to do but something needs to happen. about all these new truck issues.
I bought a 2022 3500 srw High Country 4×4 long box. I ordered it last day of Sept 2021 and got it late May 2022. The fuel mileage is averaging 11.9 around town without pulling (900 miles). I can only imagine when I hook my 5th wheel to it how poor it will be. Any reason why the drop off in mileage. My 2020 same truck got 19 in town and 12 pulling. Larry
I have a 2020 gmc 3500.
It has been in the shop 4 times to fix a DEF system error that leaves me stranded.
It’s still in the shop going in 37 days.
Gm keeps calling me with offers ie: dealer credit to purchase a new vehicle, now they just offered a comprehensive warranty. Does anyone know what their process is before they just buy it back and replace it . The lady keeps saying it’s just the process.
But I want to see if anyone kept declining the offers and actually got a replacement?
My 2021 GMC Denali HD with 10k miles is at the shop with a blown engine, The Glow plug apparently broke inside the engine while driving. They want to replace the engine. I did not buy a new truck to have a replacement rebuilt engine. I want a new truck.
2004 silverado hd 2500 and the ecm has died any relief from GM 220000 kms
I don’t see any answers to how do I find out ( who is in the buy back group ) so how do you find out ??
We have a 2022 4×4 Denali 2500 diesel truck. In the shop every couple of weeks for NOx sensor replacement!!!! Sickening that we spend more time trying to get the truck fixed than we do driving it. I sure hope they finally buy mine back. It is disgusting g to pay so much for a vehicle that doesn’t work!!!!
