Cool, now do all the motors with lifter issues for the past nearly 20 years.
dereksalem@reddit
Crazy thing is this recall isn't even for the lifters lolol what on Earth. I saw it and was like "Finally!" and saw it's only for connecting rods and crankshafts that might be badly manufactured.
What? lol
AppropriateStress4@reddit
At this point the lifters are a feature.
blueblack88@reddit
No kidding đ include every ecotec in there too while we are at it.
Gone420@reddit
Or maybe the transfer case/transmission issues in the 2014+ models
AdministrativeYam828@reddit
Whatâs the issue? I just replaced my transmission but itâs was at 140k
__JRoc__@reddit
They're trash, that's the issue
CelebrationOld1233@reddit
transfer case is fine, as for the transmission its the tune destroying the Torque converters in the 6 speeds and 8 speeds need the updated fluid and they run fine.
ShouldaBeenABanker@reddit
Will an after market tune fix the 6 speed issue? Does driving in tow haul mode help at all? On my second 6 speed at 150k miles..... Wondering when I'll need the 3rd
Signal-Gift7204@reddit
My 2.0 LNF has been solid.
jcarr2184@reddit
Ram owner here: can we include cracked hemi manifolds?
Squeeums@reddit
That's pretty much endemic to all V8 engines, big cast iron exhaust manifolds warp over time due to heat cycling.
CaptianRipass@reddit
A v8 exhaust manifold isn't any bigger than one for an L4, it'll just have two of them
Squeeums@reddit
I don't recall many modern L4s running cast iron manifolds, and the only one I can think of off the top of my head (GM 2.4l) had cracking problems.
xarune@reddit
Yup. I know the 6.2L Ford SuperDuty engines are also prone to it. One of their most common failures.
KetchupOnThaMeatHo@reddit
You guys have lifter issues too if I'm not mistaken. Same bad collapsible lifter design.
Walshman421@reddit
Yep. My lifters in my 2015 Silverado 6.2L went out at 50k miles. It was very difficult dealing with GM. No more GM vehicles for me.
muckrak3r@reddit
This specific problem is so common why have we not class actioned it? Instead each customer pays, a lot, to fix a problem they've known about for years and simply kept manufacturing defective vehicles.
bikgelife@reddit
I feel like they donât do 2019, 2020 etc bc they know we are already out of warranty. My 2020 6.2 already had a motor swap. I have 67k on the odometer. The new motor only came with a 25k mile warranty - ends at 75k on my odometer. I donât trust this engine out of warranty, so I have to dump it.
KetchupOnThaMeatHo@reddit
Apparently, they don't think it's a serious enough safety concern
fonetik@reddit
So are these American engines from Mexico or Canada?
RichardNixon345@reddit
Likely built in Mexico like the 5.3s are.
AshleyScheafferBMW@reddit
pretty sure all 6.2s are american made.
PeregrinsFolly@reddit
And for all the people in this thread talking about lifter issues (and cylinder deactivation), this is a totally separate, unrelated problem.
halotechnology@reddit
The lifter thing seem to effect every single manufacture.
No one is spared
gluten_heimer@reddit
If youâre talking about trucks, youâre kind of right, but GM trucks are affected disproportionately. To the point where itâs not the main reliability concern for buyers looking for Ford or Ram trucks.
Ihate_reddit_app@reddit
Ram definitely has the same issue in their Hemi's.
bikgelife@reddit
The DFM certainly plays a role, no?
PeregrinsFolly@reddit
Not necessarily, the scope of this recall would be far broader if that were the case, wouldn't just be those three years, or only the 6.2 (L87). Seen quite a few L87s in the last few years with shredded bearings and oil full of metal. Typically these engines seize solid to the point that we can't even turn it to get the torque converter off. The 5.3 is just as capable of having lifter failures as the 6.2, and is not included here. I do believe them in this case that they're saying that it's caused by a manufacturing defect (and not a design defect like the AFM system is).
velociraptorfarmer@reddit
Oh, so this is the issue where the rods weld themselves to the crank?
C-C-X-V-I@reddit
Looks like it
SykoBob8310@reddit
You are correct. OP should have put this info up top.
âThe connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. 2025 models appear to be exempt from this. A source says that the 6.2-liter V8s in 2025-model-year trucks and SUVs are the product of updated tooling which eliminates the underlying issue.â
ladybugpearl@reddit
my 2021 6.2 silverado is on this engine failure list as of today. I had no warnings, no error codes, no indicators of any kind. It literally died, stopped running. Never any oil loss, etc. Anyway, 77,000 miles, and always well maintained. When it stalled, It gave a low battery code, and message to put car in neutral. I was able to get off the road, it wouldn't restart. Battery and alternator are good. New engine is gonna be covered by GM. They said o-20 oil is in question, that they are saying to use 0-40 with the new engine. Could be weeks to get new engine. They said oil dip stick showed no oil, and the inside looked like glitter. I never had a low oil indicator. Will be replacing radiator too to be on the safe side.
CelebrationOld1233@reddit
If you go on the GM truck forums, almost everyone in there runs at least 5w-30 oil in their 5.3 and 6.2, because 0-20 should NEVER be in a truck. The 6.2 is the exact same engine as the corvette and camaro and those call for 40 weight oil yet the truck is somehow different? Those GM engineers are clueless.
HigherPlaces@reddit
You can safely increase viscosity for the number after the W at the cost of a slight fuel economy hit for most cars. You should not, however, change the weight of the number before the W. Engines are tested for cold priming performance with whatever viscosity is recommended by the manufacturer. So if for example your engine is specced for 0W-20 you can go to 0W-30 or 0W-40. However, you should not go to 5W-anything because you could adversely affect cold priming.
MostMobile6265@reddit
Wrong. So so wrong. Corvettes and camaros have a different 6.2. Stop spreading false info.
richrich121@reddit
Being at 77k out of warranty are they replacing it because itâs on the engine failure list? Just wondering because I just bought a 6.2 suburban last Friday đŹ
SecretSleever@reddit
Very curious about this as well.
richrich121@reddit
I doubt that. If the engine blows they canât be like âoh you didnât get slightly different oil so itâs your faultâ. It would have to be engine neglect like no oil change for 40k miles
TheAlphaCarb0n@reddit
Man, if you gotta switch oils to avoid the engine exploding that's a bad sign. A small switch should, at worst, affect power or fuel economy...good luck with engine two at least
tealsunflower@reddit
24' 6.2 Escalade getting serviced (for a different reason, lol)âcurrently at service center.
Tech said my car did not pop the error code DTC P0016 code; also stated that they have incomplete procedures at the moment. Talked about the oil swap but even he chuckled it didn't make sense they shipped all of the cars with 20 and the "fix" is now to swap to 40. He stated they didn't have an actual directive though and fumbled about even changing the oil (regardless of whether it popped the code or not). Obviously that's a mitigation tactic to 'slow the spread' of the ensuing shitstorm.
Waiting to hear back for next steps but wondering how the it didn't pop the error code.
OkDirection8015@reddit
GM tried and failed back in the 80s with cylinder deactivation. All these years later they still canât get it right. Just give up and build normal V8s.
Metalsheepapocalypse@reddit
governments are partially to blame for increasingly stricter emissions requirements
DeusMexMachina@reddit
GM (and Dodges) cylinder deactivation design is trash and should be redone. Not sure why they continue to beat this dead horse. Reducing emissions isnât bad.
T-Baaller@reddit
Because more efficient overhead cams are too fordy for them
Bob_Loblaw_Law_Bomb@reddit
Yeah the 3 valve 5.4 Tritons were such an infallible engine /s
NutzNBoltz369@reddit
More complicated as well. OHC V8s also take up more space.
The GM small block architecture is sound. The problem is too many accountants shouting down the engineers.
N0Name117@reddit
Even Ford has cylinder deactivation on the 5.0 now. Though it is implemented differently and so far, doesn't seem as problematic. Ford has also moved away from overhead cam's with the 7.3 and 6.8 HD engines while chevy built an overhead cam in their 5.5 Corvette motor.
T-Baaller@reddit
I'm well aware of the CD on the 5.0. Thanks to the DOHC engine, they can afford to be less aggressive with CD, which helps with reliability in a way that more than makes up for relative inexperience with the technology.
The ford godzilla family are nominally for a class of vehicle with more relaxed emissions/efficiency requirements (and to a smaller extent so some traditionalist people could have a ford engine with packaging benefit of OHV made in the current century)
The DOHC corvette Z06 is because GM gave the engineers the opportunity to make an engine as good as possible, free of traditionalist elements in their company.
TurboSalsa@reddit
Theyâre limited on what they can do with pushrod designs as far as timing and lift.
xXxDickBonerz69xXx@reddit
Yeah that's the same line of bullshit GM was crying in the 70s when they didn't want to put in the effort to make a good motor that meet emissions until Honda shut them up.
https://bangshift.com/general-news/car-features/other-features/how-honda-forced-general-motors-to-eat-their-words-a-story-of-pride-going-before-the-fall/
Captain_Alaska@reddit
The CVCC V8 didn't meet emissions though. It says in the report it didn't meet NOx restrictions and everyone seems to gloss over this despite the fact NOx is way harder to clean than CO2 is.
I will also point out Honda had to add cats to CVCC equipped cars by 1981.
Double_Damn_Son@reddit
Those pictures are fucking wild.
Occhrome@reddit
Nah.Â
When companies had to keep up with emissions regulations. Toyota and Honda made electric fuel injection motors that had more power and efficiency. Â Meanwhile American manufacturers shit the bed. Â Government didnât force Chevy to make crappy stuff.Â
Pitiful-Mobile-3144@reddit
Theyâre not to blame for GMâs poor solutions for stricter emissions requirements
Occhrome@reddit
Reminds me of people complaining about crappy gas tanks. The problem isnât that you canât make a new gas can that isnât crappy and meets regulations. the problem is that companies are making crap products and people keep buying.Â
alonjit@reddit
jesus. if anything, the govt is to blame for not having strict enough emission requirements.
these monsters should not be road legal. But they are. Are being given a framework to work within. If you can't, don't do it. Simple as that.
"More emissions" should not be in anyone vocabulary.
helium_farts@reddit
This doesn't have anything to do with the lifters or cylinder deactivation. This is just good ol fashion machining errors breaking connecting rods
tclark2006@reddit
Surely they got some LS3 engines in a warehouse somewhere right?
p90rushb@reddit
That's why we have cylinder deactivation deactivation
PreviousRecording174@reddit
At 59,500 miles on 22 High Country Tahoe. Any advice before this puppy no longer has 60k power train coverage.
DutchMaster6891@reddit
Why wouldnât previous years be recalled? Same issue for 2016s 2017s etc. how come they donât recall those too. When is the big big law suit happening!
GMC you screwed the American consumer. Your vehicles arenât safe and for the price, youâre thieves!
andrewjaekim@reddit
For a company making V8s as long as they have. Itâs odd to me GM still has issues with reliability.
Either-Durian-9488@reddit
The through the years inject their generally rock solid designs to heinous value engineering, itâs why GM guys are spec sheet hunters, the holy grails are the ones that work lol,
peakdecline@reddit
This specific design choice seems more a consequence of trying to make a V8 meet modern emissions requirements with maybe a mix of cost engineering.
Though... The 2.7L Turbo gasser and 3.0L diesel are some of their most reliable engines.
It's not actually "value" back to the company to produce unreliable products that fail within the powertrain warranty.
RuinedGrave@reddit
I work in Chevy parts, the 2.7L âTurbomaxâ has been solid, but my department has not been impressed by the 3.0L diesel. I also find it a crime that they designed it with a belt-driven oil pump thatâs located on the BACK of the engine.
Avid_Hiker69@reddit
How does Chevy's 2.7L Turbo engine compared to Ford's 2.7L Turbo?
Spartan57975@reddit
Comparisons I've seen show that the Turbomax is much less suited to towing than the Ecoboost
https://youtu.be/pt8zISi_qeM?si=JN6cBSzOFVoR2qhe
RuinedGrave@reddit
Canât speak to that one. The only Fords Iâm familiar enough with are the Mustangs (see flair).
Lilmumblecrapper@reddit
2 less cylinders doo do doo
racer_24_4evr@reddit
Someone at GM engineering is a Dirt Late Model racer.
ScissorMeSphincter@reddit
I have a 24 Canyon with a 2.7, is this the same engine you guys are referring to?
RuinedGrave@reddit
Yeah, it is. Iâve got a Colorado ZR2 on order with the same engine. Iâve (ironically) generally been anti-GM, so I wouldnât buy one if it had the typical GM issues. Whatâs been a good indicator for me has been that Iâve had to price out a Turbomax engine only one time. When I checked history to see what other parts I might need from previous repairs, it had no history and I was picking out parts flying blind. This is an engine GMâs been using since the 2019 Silverados. We also donât really see problems with the Turbomax Silverados and Colorados in the shop, so the whole truckâs been pretty solid.
Mimical@reddit
Yeah, the LB3 is considered pretty stout at this point and isn't likely to give you any issues.
ScissorMeSphincter@reddit
Great to hear. Appreciate the response.
430 lb torque is pretty amazing from a 4 banger
No_Airport_6886@reddit
Sorry what? The 2.7 and 3.0 diesel are the most reliable??? That is certainly not true.
DORTx2@reddit
Yeah dude the V8's are junk in comparison.
peakdecline@reddit
You can argue about the Duramax, but I've seen absolutely no indications that the 2.7L is anything other than reliable.
mr_bots@reddit
Hasnât there been timing chain and gear issues popping up? Even made worse that the timing setup is on the back of the engine and requires engine out?
peakdecline@reddit
The annoyance of the location is certainly a common topic but I personally haven't seen that much wide spread indication it's been a premature source of problems. The main issues I see with the 3.0L Duramax are the usual modern diesel ones.
RuinedGrave@reddit
Timing chain and gear issues are definitely a problem. I think we've started stocking some of the parts at my work because of the frequency it happens.
Fish_bob@reddit
Weird, by all accounts here the LZ0 diesel engine has been solid.
RuinedGrave@reddit
I see more of the general publicâs vehicles, where Reddit tends to be a sample of owners. I can also confirm that coolant control valves are a problem on the 3.0 diesels, both LZ0 and LM2.
dhargrove89@reddit
I just had a Coolant Control Valve go out on my 3.0 with 27k. Part was on back order, and the truck spent 3 weeks at the dealership.
RuinedGrave@reddit
Yep, weâve had a few on backorder recently. One part number we get pretty quick on SPAC cases, the other takes a while since other dealers canât let them go.
Nerdenator@reddit
Itâs value for the next three months, which is all that matters.
Dav_Dabz@reddit
Genuine question. Has the 5.3 and 6.2 v8 received a replacement or refresh like the 5.4 to 5.0 Ford? It feels like the design is worse than it's early 2010s design....
DOHCMerc@reddit
the "5.4 to 5.0" moment for GM was moving from the LS based engines to the newer LT based engines.
Dav_Dabz@reddit
Oh. Thank you đ¤ I forgot about the LT engines.
opeth10657@reddit
Even with the cylinder deactivation that screws everything up, I get terrible MPGs in my truck.
My fusion with the 2.7 ecoboost with nearly the same HP and more TQ gets around 4-5 mpg higher.
FSUfan35@reddit
You're surprised a sedan gets better gas mileage than a truck?
opeth10657@reddit
It's a 4k lb sedan with awd and 325hp/380tq. Been getting maybe 15mpg in the truck, car gets well over 20 with much harder driving.
The 20 year old f-150 with the 4.6 that the silverado replaced got better MPGs, and that didn't have any fancy cylinder deactivation.
halotechnology@reddit
Ahhhh still not the same different aerodynamic different tires sizes and so on
opeth10657@reddit
Yeah, if you complete ignored the second part. The exact same config, regular cab long box with a V8 F150 got nearly 20 mpg.
But hey, I can't expect people to actually read, can I?
AromaticWhiskey@reddit
Let him be, some people just have to compare apples to grapes. Sedan with actual aerodynamics vs a brick that's anywhere from 1,100 to 1,500 pounds heavier.
FSCK_Fascists@reddit
Your comments read like Homer giving car design ideas to the dev team.
https://i.imgur.com/IoPkza2.png
Bork_King@reddit
I understand your sentiment, and the v6 Ecoboost engines have proven their reliability, but there are plenty of guys who have bought Ford's and wished they got a Chevy. That's garbage on both sides of the aisle. For what it's worth, I prefer Ford's but have a Chevy truck because it was a good deal and is old enough that the cylinder deactivation wasn't a thing yet.
BlackDS@reddit
I blame direct injection
Pliskin_Hayter@reddit
Every manufacturer who uses the "shut down half the cylinders via oil pressure in the lifters" setup has issues with the lifters failing.
Honda did it with the J series.
Dodge did it with the 5.7L and 6.4L Hemis
GM does it with pretty much all of their V8s built after like 07 or so.
I'm fairly certain BMW used it at one point too and also had issues.
Its just a shitty design with an unacceptably high failure rate.
lael8u@reddit
BMW never used it.
ExplosiveMachine@reddit
FWIW the honda system didn't actually use a lifter system since the J series doesn't have lifters, it uncouples the rocker arms from the cam. Kinda like a reverse VTEC. The big problem was that the whole bang of cylinders suffered from heavy oil loss past the rings and premature wear and failure of all the systems on that bank, sparks, coils, cats and piston rings.
boilershilly@reddit
Yep, it's the downstream effects of the VCM system that causes issues, not the cam.
Mine burns oil and has fouled the #3 spark plug causing misfires twice. Finally just used an aftermarket defeat device and haven't had any issues except for oil burning from previous wear.
The manual versions of the engine without VCM are bullet proof. It's the only flaw in the J series.
6-plus26@reddit
Wondered why I wasnât familiar with this issue. I have no familiarity with their automatics
Niyeaux@reddit
Honda did it on a small minority of J-series motors, to be clear. the VCM system is only on automatics of a particular few years.
Pliskin_Hayter@reddit
Coulda fooled me when I worked in the Part dept of a Honda dealer and had to order a whole new J series every few weeks.
LOLZtroll@reddit
One every few weeks is negligible when you consider just how many of them are on the road
Pliskin_Hayter@reddit
And how many other dealers are ordering one every few weeks? Or every few days?
The dealer I worked at was on the smaller side.
Stunt_Vist@reddit
Eh VAG's 1.4/1.5 EA211 with the cylinder deactivation stuff has been fairly fine from what I've seen. Though it's also the most reliable thing they've made since the 1.9 PD after they updated the heads to fix the stem seal issues on the early 1.4. Only real dumb thing with it is that they say the timing belt is a lifetime item, which I guess is true if you wait for it to grenade your engine instead of spending the relatively little amount of money it costs to replace it after 100k. Don't know if it's sold in the US, but given VAG rarely if ever sells their good stuff in North America I wouldn't be surprised if it isn't.
WordWithinTheWord@reddit
Bean counters come along and ruin it
Occhrome@reddit
More specially its probably some 5-10% cost reduction metric they are trying to keep up with every year.Â
Occhrome@reddit
Probably from cost improvements. Itâs the main reason I see issues at my job.Â
1funnyguy4fun@reddit
The shop that put a rebuilt 6l80 in my wifeâs Yukon. I forgot exactly what the defect was that caused these transmissions to fail, but it was easily remedied during the rebuild process. Long story short, I wouldnât sweat it.
tryingtodogood_337@reddit
Wow
Nitrothacat@reddit
My â21 6.2 Trail Boss made it to 6,500 miles before the lifters failed. A friendâs failed the morning after he bought it while dropping his daughter off at school lmao.
everyythingred@reddit
you need a 6.2L V8 powered 3 ton pickup truck to drop off your kids to school?
Nitrothacat@reddit
No more than I needed a Corvette to commute to work a few years ago.
mikedanktony@reddit
đđđ
IaintNokilla@reddit
Just recall everything since 2014. They owe me about 9k for my shitbox 17 Rado.
skylinesora@reddit
I was in the same boat. Was gonna spend 6k rebuilding my 6.2 back to factory standards, said screw it, actually built it and put a supercharger on
psince59@reddit
Up until last year, the Tundra was the way to avoid all the grief I'm reading in this thread. But since it's now gone to the V6 twin turbo, the Nissan Titan is what's up if you want a reliable modern V8 and to avoid future regret lol. But that's for work. For pleasure my daily is a 98 Silverado k1500 which is bulletproof lol.
MostMobile6265@reddit
Toyota did the right thing by replacing all long blocks. Very costly to the company but owners are satisfied with that approach.
Hopefully GM does the same by replacing all long blocks. Because rebuilding an engine is going to cause many more problems than just swapping in a new long block. It will cost more for a long block so hopefully GM does the right thing.
hundredjono@reddit
Should have put the LT1 6.2 in these instead
samniking@reddit
Not like that engine is bulletproof either lol
Sandroofficial@reddit
LT1 is very bulletproof. There havenât really been any massive failures that Iâve ever read about.
samniking@reddit
Join the FB groups. Hell, even in the Camaro sub, dude had his 1LE and buddyâs 1LE LT1s fail on the same day.
These really arenât bulletproof. Theyâre pretty reliable, but FAR from be bulletproof.
Not sure how you could even say that with knowing about the AFM/DOD and lifter issues
hundredjono@reddit
1 example out of hundreds of thousands lmao
Should have told your buddy to not put the gas pedal on the floor as soon as he got the car
samniking@reddit
Stick your head in the sand, ainât my wallet lol
hundredjono@reddit
Yes it is
CelebrationOld1233@reddit
The l87 and LT1 are the same engine essentially.
Due_Percentage_1929@reddit
Our 2024 ZL1 shat the bed at 2900 miles, 9 months Seized
kaoss77@reddit
I hate this, because a 6.2 suburban is on our list. As much as I have loved some Fords in the past, the Expedition just isnât it.
RKellyPeeOnU@reddit
What's wrong with the Expeditions? Not judging, just curious.
SmokinTires@reddit
As someone who was recently cross-shopping American midsize and full size SUVs, my personal reasons for preferring GM Full Size vs Expedition are
Vhozite@reddit
I didnât know this until this comment but Chevy has been making the Suburban since 1935 according to wiki. Nameplate is 90 fucking years old.
Thanks for the nice trivia fact.
SmokinTires@reddit
No problem.
How is your Mustang btw? Itâs the first year of Coyote, right?
I would love a V8 Mustang in life, preferably S550 or S650, but I could go down to S197 Coyote to save money (though S197 might be too old by the time I find the money to buy one). Is the Coyote really as reliable as people say? When I was looking up used Mustangs, I was looking for those under 50K miles, but I see plenty of listing and stories of ppl going well beyond 100K daily driving one
Vhozite@reddit
Itâs cool. I bought it winter 2023 and have put roughly 40k miles on it in that time (sitting somewhere in the mid 80kâs). So far the drivetrain has been ironclad. Itâs mostly the stuff around it thatâs falling apart/works like shit. One of those cars where itâll always turn over but itâs 50/50 if the radio works correctly. Parts are cheap and abundant, as are guides/YT videos to help fix or diagnose any issue you may run into.
Iâd say the Mustang you want kinda depends on what youâre looking for.
If youâre just looking for the cheapest V8/400HP possible I think the 11-14 S197âs are the best value. You can find them in the low 20âs with 50-75k miles. Not a world beater in 2025 but still faster than most cars on the road.
If you have a little more money the S550 is nicer. Nicer interior, IRS, and much easier to find a Performance Pack for this gen than the Track/Brembo package on the S197 if thatâs something you are into. Also 2018+ got the 10 speed AT and (donât quote me on this) dual injection with the gen 3 Coyote. Taking aesthetics out of the equation this is what I would buy today if I didnât already have a Mustang.
Speaking strictly in terms of value unless you really want a new car warranty I wouldnât buy an S650 unless it was one of the absolute stripper spec GTs going for the low 40kâs. Itâs not a bad car but not a big upgrade over the S550.
SmokinTires@reddit
Thank you for the write up; do you daily it?
Vhozite@reddit
Yep. My Subaru is a barely running project unfortunately đ
dkmane@reddit
Check out the 3.0 duramax, got it in my Yukon, it is buttery smooth, and very torquey. Getting 20 mpg city, and 25 highway with a heavy foot.
Niyeaux@reddit
do you have seven kids or something? why do you need one of these ridiculous three-row land yachts? and why wouldn't you just buy a minivan?
kaoss77@reddit
I love minivans. 3rd row cross-over SUVs like the Highlander and are a lie, minivans are the far better choice. I need a higher towing capacity than what minivans offer.
richrich121@reddit
Literally just bought a 6.2L Suburban last Friday and drove it from CO to CA, has 1900 miles on it now.
Anything I should do or not do?
Is it basically âwhenâ not âifâ it fails?
What do we think GM is gonna do to for these engines?
No_Consequence_1106@reddit
So, what do I do with my 2021 6.2L suburban? Do we know if it will get a new engine or just a pat on the back and best of luck from the dealership?
ThatDudeUpThere@reddit
I'm just a parts guy but I briefly looked over what the put out about the recall. The engine has to be inspected and if it passes inspecting, you get a new oil cap, a new page on your owners manual and you now use m1 ow40. That's from a couple days ago so do not take that as gospel, things can always change on that.
alonjit@reddit
From a cannon straight into the sun I think is the best solution for everyone.
tclark2006@reddit
Put a hog ass cam on that bitch and send it.
bacon205@reddit
Hell yeah brother
JustGAFS@reddit
Glad I got the 5.3 I guess
walnut100@reddit
So I should just stop driving my 6.2L Silverado until this is resolved? Not that big of a deal since itâs a company truck and I only use it when I need to haul but Iâd rather not die on the highway.
CharlieBoxCutter@reddit
Iâm risking it and buying a slate truck when available. Iâm tired of these legacy car manufacturers not being able to make a decent t affordable care
Iridefatbikes@reddit
ELI5 why can't these companies just make an engine that works.
NutzNBoltz369@reddit
The engineers always do make engines that work, until the govenrment and corporate accounting turn them into the Little Engines that Can't.
redtoad3212@reddit
have no idea what changed in the manufacturing of those engines after 2020-2021.

Possibly the oil? 0w-20 is a very thin oil, and it wouldn't surprise me if they had 0w-30 or 5w-30 as the spec before 2020-2021. That higher hot weight will help keep the main bearings in a state of hydrodynamic lubrication under heavy load.
They can call it what the fuck they want, but the whole thing just sounds like it is munching rod bearings on 0w-20 on 2020-2024 castings, and that they redesigned the oiling on the 2025 so that heavy engine loads won't push rod bearing oiling from hydrodynamic lubrication into a boundary condition and spin them. Why else would the fix be to use heavier 0w-40 oil, if the engine passes inspection?

The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. 2025 models appear to be exempt from this. A source says that the 6.2-liter V8s in 2025-model-year trucks and SUVs are the product of updated tooling which eliminates the underlying issue.

Can you share the source? Iâm shopping for a new vehicle for my growing family and had written off the GM SUVs due to these engine issues. If the 2025s have this problem fixed then that changes things for me.

Iâm dumb, thanks. In typical Reddit fashion I didnât read that far.

My buddy leased a 22, and went through 3 motors. The last one blew with 4 months left so they just bought him out of it.

Absolute junk! Had an '08 with all the oil pressure issues. Chevy wouldn't stand behind it. Traded off in 9 months at a $10k loss. Never went back to GM. Seems like every motor they come out with lately has major issues the self destruct the motor before 120k miles.

It's not (just) the lifters. Main bearing was the culprit for our '24 6.2 engine failure, and I suspect for many others. Besides the wait time on replacements (it took 5 months, had to lemon law), there are multiple reports of second and third failures because they have been pulling the replacement motors from existing stock without fixing the underlying problem. Now that GM has reluctantly acknowledged the issue, I wouldn't bet on getting a '25 "retooled" engine anytime soon.

Not surprised, my friend who is a GM mechanic is always talking about how these engines are keeping him busy.

Own up on other mistakes also GM. Not throw lawyers money to hide them for u.

I saw an Escalade on drive off tags blowing massive clouds of oil this afternoon on my way home.
Imagine dropping damn near six figs on a truck and the engine immediately self destructsđ¤Ąđ¤Ą

Yea, I remember driving to Vegas last year and this super nice Escalade passed me, it looked like they had just got it. Few exits up almost getting to Vegas it was getting picked up by a tow truck, I was like damn imagine that

Looks like I'll be keeping my 1500HD with the Vortec 6000 until they pry it from my cold, dead hands.

Yikes. My mom bought a used, low-mile 2023 Tahoe in 2023, from a Ford dealership. It looks like her VIN is on the list.
Would the recall apply (be covered free) to her, having bought used from a Ford dealership? I'm glad I saw this, because she likely never would have been aware of the potential issue.

These kind of things make me a little wary to give up my old first gen 5.0 even though it has almost 220k miles on it so far. Can't say it's been perfectly reliable since I have gone through 2 water pumps and resealed the pan but it's still running and there wasn't a hint of glitter in that pan when I did reseal it.

When the 4.8 in my 06 started dropping lifters, I replaced the whole thing with a used engine. Still rocking right along, and I have a third 4.8 in the shop waiting to be torn down and rebuilt. The first gen LS isnât exactly bomb proof, but itâs close, and when something does crap out parts are cheap and itâs easy to work on. I donât ever want another truck, Iâm just going to keep repairing mine.
yvery@reddit
Really? The fix is heavier weight oil?
tclark2006@reddit
Thier fix for transmission issues was to flush the fluid a couple times for the 8 speed so I'm not surprised.

Just gotta limp it through the warranty period
This is the same company that decided to let people die because the settlements would be cheaper than replacing all the shitty ignition switches they put out there.
PeregrinsFolly@reddit
It's not a fix, this is purely temporary measure to try to slow down the rate or occurrence until an actual resolution for the problem is issued, which will likely be an engine rebuild or replacement. The vehicles that don't pass the inspection are blocked from sale, which GM has to pay a daily rate for dealerships to sit on their cars while sale is blocked. There will eventually be an updated recall issued where there are either engine rebuilds or replacements done. If they don't replace all of them, good chance there is a 10+ year special policy (extended warranty essentially) on them to have any engines that end up damaged replaced for free.
Same way the "momentary wheel lockup" issue on the 10 speeds is just a reprogramming to detect onset of the issue earlier, it's a stopgap until an actual solution is put out.
