Last week, we reported that GM issued a safety recall that included a long list of vehicles powered by the 6.2L V8 L87 engine. The problem has to do with connecting rod and crankshaft components with unspecified manufacturing defects. The recall applies to the Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV, but only from the 2021-2024 model years.
This made us wonder: why isn’t the 2025 model year included in the recall? We asked General Motors, and here’s what they told us: “A series of crankshaft and connecting rod manufacturing improvements implemented on or before June 1st, 2024, addressed contamination and quality issues. Model-year 2025 vehicles were built after these improvements and are not included in the recall.”
GM’s decision to issue a recall follows a series of lawsuits, investigations, and engine replacements regarding consistent problems with the 6.2L V8 L87 engine. For reference, the General Motors recall number is N252494001.
“GM will voluntarily recall certain 2021-2024 Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV models equipped with 6.2L L87 engines to resolve manufacturing issues affecting some engines,” General Motors said in a statement to GM Authority last week. “The safety and satisfaction of our customers are the highest priorities for the entire GM team, and we’re working to address this matter as quickly as possible.”
General Motors trucks and SUVs affected by the recall will be inspected for manufacturing defects. Vehicles that pass inspection will receive an engine oil and filter change, this time using high-viscosity 0W-40 Mobil 1 Supercar oil. The owner’s manual for L87-equipped trucks calls for 0W-20 oil. The oil fill cap will also be replaced (to reflect the new oil type). It’s unclear what happens if an affected truck does not pass inspection, but an engine replacement is likely.
If you own one of these vehicles with the problematic V8, General Motors will notify you and give you instructions on what to do next.

Hmmm, oversized lifter bores, con rod bearing failures, and only on the 6.2. did they have a diversity hire as the quality engineer overseeing the 6.2 during a certain administration that was in full force from 2021-2024? And the rectified issue in June 2024 was the firing of said employee?
Sarcasm ON:
You must be correct, because everyone knows white males are the better than anyone else at every job in the world. Any job not occupied by a white male must be because no white male wants it or because of a DEI hire.
Sarcasm Off:
Except for Veterinarians. 63% of practicing Veterinarians in the US are female and 87% of vet school students are female. Looks like white males obviously can’t compete in at least one profession. It may be that women are just smarter and more empathetic than men and like dealing with animals. It appears mediocre men who used to go to vet school just to make lots of money are too stupid to get into vet school vs. smart women.
Well then, we need DEI for White men in the veterinary profession. LOL.
You already have DEI in the Veterinary profession as well as ALL other professions. Now they have to compete. Oh the horror of it all
I hate the thought of a potentially incompetent DEI hire working on my dog. I hate it even more when it’s the person flying/trying to fly the airplane I’m sitting in.
So you’re saying this is a woman’s fault? Mary Barra hater.
DEI is nothing but reverse discrimination. Your skin color and ethnicity and sex have more weight than your qualifications do for obtaining the job. Qualifications should be the only criteria for a job. DEI has other ideas, which is wrong. Would you want someone who got the job as a doctor because of their color over someone else who didn’t get the job because they are more qualified to operate on you?? Yea, I didn’t think so.
If pre-2019’s didn’t have the problem, it should be pretty easy to track down the cause. What changed in 2019? New supplier, different bearing composition, different oil, rod/rod bearing cap change? Plain Babbitt bearings wipe due to overheating. Babbitt is soft like lead and melts (wipes) at a low temperature. Bearings overheat for a few reasons, lack of lubrication due to inadequate lubrication or too light of viscosity of lubricant both cause overheating. Or the bearing contact surface is too small (journal diameter or bearing width, both cause too much pressure on the bearing surface which overcomes the lubricant film causing metal to metal contact between the bearing and crank journal surfaces. This increased friction causes heat which eventually melts the Babbitt. When the Babbitt starts too melt that creates too much clearance in the rod -crank journal ( that’s when the knock starts) once the knock starts you have a very short time before the rod cap or rod breaks causing catastrophic damage.
It’s called dirt left in the casting after machining. Dirt that is larger than the bearing clearance and consequently destroys the bearing and then the engine.
I love how anything that breaks is now the fault of a minority hire, as if there’s somehow only one type of person that somehow can be a quality engineer.
The insecurities of MAGA is truly astounding. How are you guys running the show right now? The true colors are really showing, bleeding. Enjoy your free for all. It ends during midterms. Thank goodness.
Biden’s emissions and unrealistic mileage mandates caused GM and others to use 0/10 and 0/20 engine oil. GM now says to use 0/40 in these engines …..so now they might not pass strict emissions requirements. Biden did this.
Ironically, it’s actually Trump that did this (or people with his mindset, I should say), as all the design, machining, manufacturing and production that went into the L87 engine was completed setup between 2016 and end of 2020. So guess what, MAGA meathead? Biden wasn’t in office yet. 2021 model vehicles were produced in summer of 2020, and all ’21-’24 vehicles came off assembly from plants set up before the end of 2019. Trump was in office till January 2021, and that manufacturing process was already up and running all under his watch. Way to look like a genius while not looking at the facts.
Deregulating and removing inspections across the board and that particular mindset that kicked many safety standards and protocols out from everything ranging from manufacturing to the FDA and everywhere else allowed for unclean machining, which resulted in engines with rods and bearings suffering catastrophic failures due to faulty machining and contamination. Trust me, Democrats love nothing more than more government involvement, inspections and slowing down the process. Sadly, in this case, that wasn’t done. That being said, GM did this, and it was mostly done in NY right here in the heart of America during Covid, when it became harder to find reliable employees than any other time in history… and that also started during the Trump administration and shutdowns, then chip shortages… all under his watch. And I am a moderate who hates both guys. Just saying, if it’s Biden’s fault, it’s even moreso Trump’s fault. He set the table for the disaster to be swept under the rug, it just became too much a mess it needed to be cleaned up. Then again, this isn’t a political issue so much as a result of the Covid supply chain and employment issues that resulted from …. oh wait, that was Trump too. Oh well, fun conversations to be had, but these issues stemed from the Trump administration Part 1 and got dumped in to us now. Biden, like most things during his presidency, was just along for the ride, blissfully unaware.
When you have a female CEO and let accountants run the production, this is what you get.
LOL yeah, GM was SOOOOOOO good at quality when they had white men as CEO.
All this DEI stuff can be quickly resolved simply by removing any references to sex or race from all applications for education and employment. A step further could be assigning a bar code to applicants so they can’t see names that hint at origin such as Hispanic or Asian names. Then they will only see qualifications they are looking for.
strange names will give it away
ignorant people lacking a spine will do it too…
Has GM or any other source supplied data an how many/percentage of these 4 model years 6.2L’s have an issue?
Is it 0.1%, 1%, 3%?
Its estimated to be % .0004 !
it is 3 % overall, across all models with 6.2.. Including GM and GMC
There has to be a GM technician that visits this site that has torn down one of these motors and has seen what the defect actually is. It sure would be nice to know and changing the type of engine oil isn’t going to fix the problem. Most likely just prolong it. Actually have mine scheduled for this thursday to have it checked. Fingers crossed.
My guess is shearing due to too thin oil. Add just a tad bit of oil dilution from gasoline and it gets really bad. Due to frequent shorts trips and infrequent oil changes. Engines run a tad rich on start up and will thin the oil if thats the typical way it’s used. Especially in cold climates.
the dealers don’t have the parts to even do the recall I don’t see how they can even give you an appt.
GM did the same thing with their 8 speed transmission, flushing & changing ATF fluid and replacing torque converters. I owned a 2015 Escalade and had numerous flushes and torque converters. Frustrated I traded it in and bought a 2017 Escalade, only to have the SAME problem. $300K later I ordered a 2023 Escalade with the new 10 speed transmission. And now to find out the 6.2L engines have manufactured errors. This is ridiculous. So much for quality control management. I have been a loyal customer of General Motors for over 60 years. Their premium flagship Cadillac Escalade is now diminished to the grade of a cheap KIA
The jokes on you for wasting $300,000 on Cadillac junkmobiles.
You clearly need to have other people make financial decisions for you. Like Britney Spears.
I love how everyone keeps calling these outfits “dealerships”. These idiots on this entire website think they are getting a “deal” when their POS is in for weeks at a time and they get a free rental.
They also know their “Service Manager” on a first name basis.
They are seriously lacking in mental health.
“Loyal Customer” while they have been importing Hindus as well as shipping jobs to Mexico for $3/hr.
Who are the idiots here? You’ve all been sold down a river. A river polluted with Hindu fecal matter.
Thank you Mudman, from a guy who probably retired from GM assembly line and drives a Toyota Prius.
How did you go through 300K????????? Did you not get these fixed under warranty as that’s what they were? Did you light each Escalade on fire before buying a new one so it had exactly 0$ trade in value? I can’t take your whole comment at face value so I’m assuming it’s made up, and in the meantime I’m going off my experience with the 8 speed which was that it’s the best transmission GM has ever made.
I assume his $300k figure includes the purchase prices.
Maybe so underwater on his previous impulsive luxury vehicle purchases.. I have not bought a new vehicle since 1978. It is crazy to buy the latest model and suffer depreciation.
stop with the kia bashing, go drive one
Sorry to hear about your Escalade problem. Like you I am a life long GM guy. Had a string of Suburbans in the 80s and 90s with only one bad radiator. In recent years we have downsized to Cadillac XT6s. We have had three and love the V6 power. I understand that others in its class now have four cylinders only. Maybe you can downsize too.
I’ve seen several, the rod bearings are stacking, this is normally due to insufficient lubrication.
I have a 2019 L87, which is not included in the recall. At first I thought the reason it was not recalled must be because the problems started with 2021 MY trucks. Now I am wondering if the problem is with all 2019-2024 L87s and if GM’s proposed solution only includes L87s that might be under drivetrain warranty. If so, GM’s proposal would not address the safety issues that should concern NHTSA. I am hoping the NHTSA report will answer this, if GM doesn’t see fit to do so before.
Further, if the problem did start with the 2019 MY engines, shouldn’t GM recommend the “bandaid” (changing the oil viscosity to 10-40w) for those engines as it has for the recalled 2021-2014 engines?
I have 10,260 miles on my pampered 2019 Sierra 1500, which has had six oil changes. I don’t think it is fair to have to drive anywhere wondering if my engine will grenade without warning.
I have a 2020 Tahoe with a 6.2L engine as well and I am thinking the same thing. Does anyone have an answer.
The 2020 Tahoe has the L86. Not the same engine. Will not fall under the “recall”. Also should not have the issue aside from the normal lifter failure.
I also have 2019 6.2. I have 62k miles now. Some dealer oil changes and some myself. Last oil change was January 23 this year. April 24 this year I was driving down the NJ turnpike at 70 mph when my warning light and chime went on. I looked in my rear view to move over and saw nothing but smoke. I thought for sure it was a rod through the block. I got to the shoulder and popped the hood . Oil was everywhere. Hopped back in and didn’t like how close I was to the rush hour traffic. I tried to start it and it purred like a kitten and no CEL on. So I pulled further up and over closer to the guard rail. Didn’t realize at the time that I didn’t hear and rod knock or any noise from the engine. Had the truck towed off the TP next day to my repair shop to see what happened. Come to find out my oil cooler line separated right behind the radiator at the crimp. There was absolutely no damage to the rubber hose, not even a scratch from the crimp. Hmmm… A Friend found a TSB from Chevy recalling all 2019 6.2 liters up through 2022 for vehicles in Canada and Alaska only. Stating the issue is due to extreme cold… Hmmm … Checked forums and there are people from Ohio and NY and now me in NJ that this happened to. Huh, I guess it doesn’t get cold in the northeast??? Called dealer said my truck doesn’t qualify for the recall. I forgot… My engine did seize! Dealer said vehicle needs to be at their shop for any consideration of assistance from GM. They can’t look at my truck for 2 weeks and engines are backordered with no ETA said they have several customers waiting for engines for over 2 months, no ETA. Then be another month or two to get on the schedule for installation. I’d be without my truck for 4 months, at least. I sourced a reman 6.2 should have it with in a week and truck should be fixed mid to late May. Add insult to injury, I’m in the middle of having Cancer treatments and need my truck for travelling to my appointments. No extra cars in the family. SO WIRD TO THE WISE, CHECK OR REPLACE THOSE OIL COOLER LINES ON THE 2019’S!!!!!
I had this very same issue on my 2019 5.3L Silverado with 17,000 miles on it. Only in my case the engine seized within 10 seconds of the bang! I left oil all over the road. I was lucky in that the dealer was able to get another engine within a couple days and had my truck back the next week. I don’t buy the hose crimp excuse though. I read somewhere that what GM really found was there was problems with the variable oil pumps causing oil pressures to spike really high, thereby causing the oil coolant line to blow. I find it interesting that the line would blow outside of the winter months.
I have a 2019 GMC AT-4 with the 6.2 V8
With right at 90,000 miles. Oil changes regularly and 1 battery, 1 serpentine belt recently and 1 set of tires!
Engine Has Never Missed A Beat!
Love It!!!!
Why are the 2019 and 2020 years not included in the recall? I have a 19 Sierra SLT with the 6.2L L87engine. I bought it last fall with 92,000 miles on it. I got 400 miles on it before rod bearing failure. No extended warrantee. It didn’t blow up but had the dreaded rod knock. My mechanic son and I removed the pan to find 2 rods that were black from heat. The rod bearings were wiped out and the crank journal was scored badly. I found a 27,000 mile 2019 engine at Spalding Auto in Spokane, Wa. I paid $6700 for the engine and they installed it for another $3500. By the time it was done it was almost $11,000. It had a 90 day warrantee from them. So now I have $46,000 in a 2019 truck that I am afraid to drive. Thanks GM!
I had a 2020 suburban that I had to trade in with a blown engine. At one point there were shards of metal in the engine. The final blow was the lifter kit went out and caused three of the 8 cylinders to blow. Chevy told me that once they opened it up, it could end up costing between 12 and 15 thousand so we traded it in. It wasn’t even paid off. But supposedly there was nothing wring with the 2020…. I beg to differ
Sounds like GM used the same bearing manufacture Toyota Did in the Tundra that eats it bearings too.
Worst part is 2025 Tundras and 25 6.2s have both had problems.
I won’t touch any of the newer cheaply made QC products all mfgs produce now.
With Gen Z at the wheel (some youngsters who don’t care), Ms Mary who wants to promote her BS EV agenda, this is a disaster…
Everything is outsourced for bid. As bad as it gets sometimes the OEs can’t control the quality of the outsourced parts it that manufacture chooses to not build the parts as specified in the original contract. We all find out after the fact as our vechicles implode due to bad parts
I would like to know what type of inspection dealers are planning? I have heard a borescope inspection – which I am very familiar. IF there are material defects – casting flaws in the rods / crank – etc. it will be practically impossible to detect with a simple scope- Eddy current / magnaflux / x ray – maybe- Changing the oil viscosity – ???? I don’t think so……………
The inspection only consists of looking for a DTC P0016 trouble code in the computer.
exactly and if you have that you have a check engine light on and people arent driving around with that on so basically everyone is getting a new oil cap and sticker and they are moving on.
I have a sneaking suspicion that the ‘inspection’ will be; if engine is not knocking-replace oil with 0-40 and change oil filler cap. Return to service.
The inspection only consists of looking for a DTC P0016 trouble code in the computer nothing more.
This will date me. I remember when gm made thier own bearings. Those morane high rev 400 bearings were as durable as the clevite 77s. Can’t beat a brass body core with quality babit
I recall the 305 camshafts going flat back in the 80’s.
As for the rods failing, back in the day, I’ve rebuilt countless sbc 350s even a few lt-1 motors with spun rod bearings where the rod did not break. The rod journal and crank was junk but it held together. Modern rod quality is questionable.
Well, they are just Ni$$er trucks. What do you expect?
My 2023 Sierra has been in the shop now for 2 weeks they told me the whole inside of the engine was rainbowed whatever that means. They were asking warranty department to replace complete engine long story short they are ordering parts for a complete rebuild they have a pickup on the rack been waiting 2 months for engine my parts are supposed to be delivered in 4 to 6 weeks good thing I bought extended warranty mileage on vehicle is 14,500 What a mess this is thankfully my dealership has given me a new pickup to drive in the interim don’t know all dealerships can do that
I’m pretty sure it was the Hindus GM hired. I think GM scabbed them from Mahindra.
Whatever change GM made in 2019, didn’t work and caused this problem. Someone needs fired, this is just crazy and shouldn’t happen when you have a competent engineering, supply chain, and quality assurance departments.
Sounds like it is time for Mary Barra to invest those Stock Options in the Millions she gets to make a quality product.
I’m ready to buy a new Silverado but I damn sure don’t want a 6.2 and I’m pretty suspicious of the 5.3’s, that leaves the 3.0 which has a longer warranty than the gas engines, I believe. However, now I’m hearing that there are issues with the 10 speeds. Maybe I should just drive my existing Silverado a while longer or put a manual transmission from the Camaro in them, I’d take that as long as it has a granny gear.
I’m in a 2007 Duramax. At 250K miles and expect I can easily get another 200 from both engine and transmission. Normal maintainence to date. No way I can afford $90k to replace it being retired now. Steering box was required though. Seems vehicles in the last 10 years or so are always having ‘serious issues’. Oil consumption is a big one. Low friction rings?
Suspect many people will hang on to their current vehicles if possible.
The new 3.0 Duramax is looking attractive other than the oil pump drive belt.
>> The new 3.0 Duramax is looking attractive other than the oil pump drive belt.
Well, they are just Ni$$er trucks. What do you expect?
Issues with ten speeds don’t approach anywhere near the number that Ford is having.
Sounds like GM found a solution to get them out of warranty, and then you get the “oh sorry, your out of warranty”. Not doing jack until I get that letter.
Exactly. If my truck passes “inspection”, they’re changing the oil and I’m driving it directly to the sales dept to trade it for a diesel Suburban.
Maybe true, but I am quite scared about the costs on THIS and THE TUNDRA ENGINE.
Not a fair comparison, but the V35A costs 25k-32k officially from Toyota. And you have to lift the cab.
Build dates beyond the failed units have come too..for Tundras .
Yay! Everyone is gonna get an oil change! That will fix it!
“However, now I’m hearing that there are issues with the 10 speeds.”
This is an understatement. Massive problems and no fix typically.
10260 miles driving to Quick lube on a 2019 and 6 oil changes….. Every six months whether needed or not?
Yup, changed every time the oil got to 20% according to the reminder gauge. Dexos 0w-20. Upgraded filter each time. So you can see where I would be mildly upset if I now learn that the recommended oil weight is part of the problem and that GM should have recommended 0w-40 from the start.
I had a 2017 Sierra 4WD with the 6.2 and it sucked 2 lifters, bent push rods, scrubbed the cam, etc. I was going 45 mph. Truck had 67K miles and out of warranty. $3K later I picked it up from the dealer service center and sold it. Bought a 2023 Sierra 4WD with the 5.3 in Dec 2023. I’ve put 7,200 miles on it, had one oil change and NO problems. I’m 70, always had GM pickups and cars. It’s BS that GM can’t source quality parts for these engines. BTW, my truck has a 10 speed trans and never a problem with it. GM didn’t want to address the 2020-2024 issues until so many lawsuits were filed they were forced to do the right thing. Pitiful.
The more I see of the new GM trucks, the more I am happy to keep my 2003 running. Even given the 22 year difference, my 2003 will likely last longer. Too much penny pinching going on (for an $80K vehicle).
So, clearly GM is on the verge of losing a hefty lawsuit as they admit to knowing about the problem and still continued to sell vehicles with the problem until last week.
Good article for a change. Addresses the issue why my 2025 Yukon Denali Ultimate was not included in the recall. Extremely useful information. Keep it coming! Now if we could only find out why the Surround Vision Recorder does not work.
My 2019 had a new engine put in at 61000 miles. Will the new engine be covered by this recall?
All of this talk about bearing failures has me remembering back to my early days working on cars and trucks. I was a diehard Ford guy then and had multiple 1960’s Ford cars and trucks during the 70’s and early 80’s. I distinctly remember the infamous Ford main bearing knock. It was usually heard when a well worn Ford engine was hot and idling, hot thin oil and low rpm and low oil pressure. You could lightly goose it and head the low hollow knocks deep inside the engine. Never had one fail, just them full of fresh oil and upgraded to 10-40 or straight 30 weight to take up the extra main bearing clearance. Ahh, those were the days when you could listen to the engine and understand the issues going on.
What does this do to the trade or resale value and how is GM compensating for this. A new oil cap isn’t going to give any prospective buyer a sense of security.
A GM engineer did tear down a 6_2 and found that it had defected or improperly installed piston wrist pin clips ! Which causes the piston and rods to become off center ! The stress bends the rod causing it to exit out the block ! Only 40 known cases to date so thats a %.0004 failure rate ! The case most likely will be dismissed ! And going to a 0w40 engine oil was always the better choice !
Such a shame. What started out as the LS design and most reliable GM V-8s ever made slowly went down hill over time. First it was AFM or DFM as it’s called now causing lifter and cam failure, to now this defect. All to save a mile or two per gallon. Hey, if I can afford a Tahoe, I can afford the gas. Pay the tax and keep these trucks real. Guess I’m hanging on to my older model with 200k running perfect.
I agree 100% Gary, AFM and DFM along with start stop are just not things you need on a Truck or large SUV. I will gladly give up a mile or two per gallon to not have all these issues. My next truck will be a 2500 silverado with the gas 6.6. Plain and simple, 8 cylinders firing all the time!!!
Great job, Mary .
I hear everything you guys/gals are saying about the quality and engineering and sourcing of parts but listen to this. They were 2019-2024s ? What was going on during that timeframe? No if you recall seeing stockpiles among stockpiles of these trucks just sitting in fields during the pandemic as no one was buying anything. They sat for years. Did anyone from GM go around and run these vehicles while they were left sitting in open fields? How long does it take to the oil to drop down to the pan? Once things started to open up and we went and picked up these vehicles for sale, wouldn’t the top of the motor be “dry” from gravity? Whether you believe it or not the mere thought of sitting for months on end is not good for the motors. Ask any collector. Just a thought. Good convo for sure!
This just in from GM- one of the causes is from “sediment contamination buildup in the crankshaft journals”. Now how does that happen?
Just remember…
It was a deliberate decision to remove “GM, Mark of Excellence” from their entire product range.
Why? Because they deliberately decided , at the Board Level, to NO LONGER embrace Excellence!!
Now it’s just “GM, Mark of Excrement !!!
My 2024 Escalade threw a rod through the oil pan, and maybe part of the crankshaft out the side according to a second hand comment from the tech replacing the motor, while I was driving the family on our spring break trip in March. GM is not handling our case well – their customer service reps are not properly trained and they can’t get replacement engines quickly enough. There were four others like ours in for engine replacement at the same dealership in a remote west Texas town. I believe the .0004% stat is probably understated. The dealer offered us 67% of what we paid a year ago for the car – they’re admitting the value is significantly impaired by their known defect. On top of that we got hail damage while waiting for the engine to arrive.
It took FOUR model years to discover and acknowledge that they have a problem and finally correct it for 2025MY products. Unbelievable.
Did they “voluntarily” retire their quality tracking and service engineering people too? They used to have manufacturing quality tracking teams that did nothing but track, monitor and react to “quality spills” as those guys used to called them. I even knew a couple of those guys.
GM still has much of their powertrain foundry/casting and machining operations in-house so if indeed the issue is due to manufacturing defects in their connecting rods and/or crankshafts as per their statement it’s almost certainly on them.
COVID plus poor quality.
Toyota still did not correct their issues for MY25s as well. They NEVER RECALLED HYBRIDS. And those have failed as well.
The scale of this issue means that they had to conduct such assessment.
When time comes they will include the 6.2s as well from 2025.
And the volume this recall will take will MAKE SURE that there will be backorder for 6+ years…or maybe 8 years.
2023 cadillac ctsv blackwing. 6.2 supercharged. 24k miles. Blown motor. 1 quart of 10 40 oil. For every 300 miles. Been at the dealership since early March.
I have a 2025 Tahoe with GM 6.2L V8 engine. Less then 7000 miles and we have the same problem. Just had the dealer tow it from my driveway on Sunday.
That’s wonderful. GM gave birth to yet another Democrat.
George, do you know the build date for your 2025 Tahoe that has the problem?
It was the day Tyrone smoked a blunt and drank a fifth of Evan Williams in the commode while dropping a deuce in the company’s Union toilet.
Boy this is terrible.
If I read this correctly, only 3% of these have been reported 800,000 built /28,000 reported failures.
Outsourcing major components comes with a huge risk, you lose control of quality. It was bad enough when it was just an alternator or water pump. The drivetrain issues are inexcusable. Kia and Hyundai have had major engine issues for the past ten years, every major manufacturer have had drivetrain problems and from my experience in automotive service, 10,000 oil change intervals are part of the problem! It might be more convenient for the consumer, but it destroys the engine. Low oil or viscosity cause improper lubrication. Most consumers don’t want to be bothered with maintenance, but it’s much cheaper in the long run to maintain a vehicle properly. Owners need to be more informed about caring for their vehicles, read the owners manual. It will save you time and money. EV’s will be easier to maintain from a maintenance standpoint. Push rod engines will become a thing of the past, if manufacturers don’t address the issues that seem to plague the industry with endless engine failures.
General Motors said in a statement to GM Authority last week. “The safety and satisfaction of our customers (became) the highest priorities for the entire GM team (right after we got caught), and we’re working to address this matter as (cheaply) as possible.”
Different engines we bought a 2008 Tahoe Hybrid with the 6.0. At 120,000 the engine killed itself. Perfect maintenance oil changes babied. Sent it to carvarna during Covid. They gave me decent money for a dead cat. They replaced the motor and sold it. Liked The Hybrid system in the full size. Bought a used 12 Escalade Hybrid. Got it too 120,000 miles and the 6.0 also killed itself. Thanks we had a great power train warranty. Got a brand new 6.0 installed. Cylinder number 1 on both motors collapsed. I’m sure we weren’t the only ones. But what do it know. Good luck all you 6.2 guys.
i own a 2022 Sierra 1500 6.2L about 30,000 miles. Currently haven’t had any issues so far, although I took it in for its oil change at my dealership. This was on May 2nd, 2025, I talked with them about this issue to see if they could check for the p00016 code to see if I was a part of it. They said they can’t check it because they weren’t given the authority by GM. I’m wondering if this is negligence, and why won’t they check it for the code, and im worried that because they won’t check it, what if there is something wrong yk? I don’t want anything bad to happen. I just wish they would check it, and if it does have that code, I wish they would replace the engine. What are your Guys thoughts on this ?
