GM To Repurchase Silverado HD, Sierra HD Units Due To Duramax Diesel Engine Quality Issue139
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.
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.

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
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.
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
