As a chevy fan boy, let me say, no one hates GM more than those of us that drive them 😅
You’re not a Chevy fan boy, you’re a ford fanboy typing some stupid ass comment.
Agreed. I wish GM would allow Chevy to leave the corporation and let Chevy sell itself on the stock market
Yeah same thing here my 19 just crossed 60 K and the transmission is shot looked into that turns out there’s a class action lawsuit for the transmission as well fuck me if you can’t trust a Silverado anymore it’s all over
What I hate is their service,,,,,,I listed my cars but I also own a bought new 2022 Toyota Corolla SE as my daily to protect my baby’s by putting miles on them,,,but Toyotas service is so much better,,,I don’t get nervous and upset when I have to take it in for service 😂 with chevy I get a stomach ache and my palms get sweaty cause I know I’m gonna lose it!
Yes had my first and last GM 13’ Tahoe great vehicle 160k. Can’t can’t buy another. GM seems to be really going down hill won’t take the chance on another one . Toyota gets my next purchase
It is just insane to me that gm is still having this issue! I bought a 2007 suburban in January of 2020 with 120k miles. In June of 2020 an AFM lifter collapsed so I tore down the engine and rebuilt it myself (keeping the afm system because I didn't want to replace the cam and get a tune). I removed both heads and replaced all 16 lifters. The head gaskets were not matching so I assume that the truck had already had this issue before my ownership. In September 0f 2020, almost exactly 5000 miles later and 3 days after an oil change, another damn lifter collapsed! I bought a 2020 Toyota tundra out of frustration because those things are supposed to be bulletproof. My plan was to fix my suburban and sell it. I removed the engine, fully cleaned the internals and externals, upgraded the oil pump, and replaced all the bearings, rings, and seals you can think of. I put a BTR cam in it and LS7 style lifters to fully delete the afm system. I ended up keeping it because I think it's pretty cool to drive something I built and it has been reliable for the last 15k miles. So my question to GM is: why can I, a 22 year old who learned everything he knows on CZcams, build a more reliable 5.3 than one of the biggest car manufacturers in the world?
Because you don't have to answer to the EPA....
@@oddball0045 not exactly the same thing but I live in California and my suburban just passed smog 2 weeks ago.
@@braedenboss5636 because it's subjected to past the smog tests for the year that vehicle was manufactured. Newer vehicles have way stricter emissions standards
Because you actually have a brain 🧠
WORD!
GM needs to make it right, but thanks for being smart and pointing out how class actions work. Attorneys will make millions and including GM's Defense attorneys, real plaintiffs will get peanuts. It's sickening
So why make the video? You are the same folks that will go out and promote a Hyundai, KIA, or Genesis product despite their class action lawsuit. A bunch of clowns 🤡
How it always works. The system isn't designed for us. It's designed against us.
Money grubbers
Remember gm’s fuel tank class action settlements ? They gave you a $1000 voucher towards the purchase of a new vehicle 😂 Gm’s an American embarrassment.
Just found your channel and been watching the videos. Great info on all. Thank you. I have a 2021 Silverado LT Z71 4WD. I dropped a lifter at 7000 miles and it sat in the dealership for 9 weeks waiting for parts. Then at 18000 Dropped another lifter and sat at different dealership for 2 weeks waiting for parts. Now my truck has about 33000 miles and running low oil pressure on the guage. Start the truck up after sitting awhile and oil pressure is good. Drive about 10-15 miles oil pressure drops. When I say drops it is on the first line above 0. Warning lights come on and drive it to dealership (hoping motor would blow up to get a new motor) leave it running for them to look at it. They put the computer on it and says sending unit out of spec. I look at the service writer and said "Really thats what you see. Would have never thought that." So now what. No parts available and no loaner available. Drive it until we get the part in. Been driving the truck now for about a month and half. Got a call sending unit came in we will replace this Friday. Love my truck but do not love the issues with this one. I have had many a chevy truck and even tried another brand once and that will not happen again. Years of Chevy Trucks I have had: 1985/1997/1999/2000/2007/2013/2015/2017/2021
Might as well sue them for the Transmissions and the faulty A/C as well! They know about that as well. Ohhhhh the pain of being a Chevy man!
Yes sir, 2016 Silverado, Trans went at about 112k, AC went at around 80k
@@dannydukes5 Lots of transmission and A/C failures at 15,000 to 20,000.
The 8 speed transmission is designed by ford, ford has the same problem with the same transmission
@@brianb1588 I’d heard this too that GM and Ford co developed the 8 speed. Lifelong Chevy man, but honestly was hoping this would have been good news when I heard it. I guess not 🙄
Yep may as well call all GMs defect don’t forget about their vacuum booster pumps that create hard pedal aka no brakes. Got told by the dealership burning a quart of oil every 800 miles is normal guess we will be going to an abnormal Toyota.
This class action suit should be opened up to EVERY GM product with this junk AFM installed. All one has to do is surf the internet for information regarding the MASSIVE engine failures in GM vehicle with the AFM system! There are SO many people who have had to come out of pocket to either rebuild their engines or replace them due to this junk system! I think GM should have to reimburse every one and offer to perform the AFM delete mod to this motor in ANY vehicle that has it!!
I totally agree. Why not include the ‘07.5-‘14 years??
It’s an “emissions device”. They won’t offer to delete it
@@ChopsMahone your exactly right it's actually your local EPA fault and gm not wanting to discontinue the tried and true pushrod v8 trust me if the EPA wasn't around we'd have 5.3 v8s rolling around with no AFM
Catastrophic failure in 09. Result crate eng.
14’ silverado, 140k miles. Just spent $10k to replace my motor.
I'm glad this popped up. I needed a new truck, been defending buying a 2013 4.8 instead of anything after and this is exactly why I did that!
My 2021 Trail Boss (5.3) just went in the shop today with the lifter issue. Will be stopping by tomorrow for and update. I will be pushing for both banks top be replaced. We will see how that goes. Thanks for the great video.
👍🏁 please keep updating us on this problem love the videos
I love GM, that’s all my father and I have ever owned in terms of trucks. But in my opinion they have too many MBA-types running the company, they just flat out do not focus on bringing the best possible product to market.
Same here GM all my life and now I just see quality going down. It’s a shame
I wish they would undercoat their vehicles with something other than wax.
It's because the new CEO sucks.
@Cameron Cannon
That has been the case for decades
What I dont understand is why people keep buying
gm saw Ford didnt fail in 2008 and thought hmm i too could vetray my customer's trust in brand name in ordee to make short term profits and award bonuses to execs...
I am 69 yrs old. I have owned nothing but General Motors cars and trucks since I got my drivers license in 1969. I have owned Pontiac's in the late 1060's. Then Oldsmobile Cutlass from 1977 until 1986, then Chevy Monte Carlo's until 1988. Then GMC Jimmy and GMC pick ups buying my last GMC pick up in 2017. I was trading every couple of years and never put more than 35 to 45,000 miles on them. I decided to just keep the 2017 since I was retired by that time still it had less than 60,000 on it and I dodged ever having the problems with the AFM/DFM. although I had purchased the plug in over ride device for $100.00 and it worked. I know the owner of my GMC dealer very well and had always bought my trucks through his dealership. I went by his home for coffee one Saturday in late 2020 and told him I was ready to get a new Sierra Denali. He point blank told me that with all the issues with engines and now transmissions he could not recommend buying one. Instead he sent me to a Toyota dealer where he knew the owner, he recommended a Tundra Limited. It came standard with a 5.7 V-8 and a 6 speed automatic transmission. No cylinder deactivation or the hated "Auto Stop" that cuts the motor off when stopped. A drive train with 8 years of service and no repeated issues. He found me the color I wanted with leather. I couldn't believe I was taking the plunge but I did. it's a new 2021 and Toyota's last year for their V-8. I'm so glad I listened to my friend, I love it, it drives great and the ride for a full size pick up is very good. I was getting around 17 miles to a gallon and 18 to 19 hwy in my 2017 GMC and the Toyota is about a a mile per gallon less on both. The Toyota doesn't have the styling and the interior isn't quite as nice of the Sierra or Silverado but at this age I'm not willing to fight the battles. I believe the 2022 Tundra's have the cylinder deactivation and auto stop. No more that I drive I believe this Tundra will out last me. I have always stuck keeping my vehicles serviced on time.
Great video. As a mechanic I see this way to often. Poor design or stupid idea to disable cylinders . Gm knew about this problem a long time ago. Hopefully they will now do something about it
My 2008 Silverado had a valve stick briefly so I deleted the afm with a super chips tuner and haven't had any issues since. It's been about 2 and a half years now and I'm at 260,000 miles. Makes life so much easier. 🤘
Heard that brother. My 08 has 245,000 on it. This truck is a shame in some ways and incredible in others. For as old as my truck is , it drives surprisingly good and so much of it has just been as stout as it can be. I still get compliments on it and some people less car savvy think it's a new truck. Some of the things done though just defy logic. So many cheap decisions made. It's frustrating to see a truck built so perfect yet so crappy.
Just be aware, you didn't delete anything with a tune. You just turned off the AFM function. The lifter is still in your engine. A delete is possible but requires all new parts and runs around $800.
@@andrewsbbq haha, of course. Using the word "delete" is just a phrase that is used. As long as the truck stays running in V8 mode, I'll be fine. If I ever have to tear into my engine to fix something, then I'll consider replacing parts for an actual delete. Thank you though.
@@armandohernandez1412 I dunno, even on the major GM truck forums one is known as a "delete" and the other as "deactivated" or "disabled". Symantics maybe for some, but is a key difference.
In any case, just pointing out the tune didn't delete anything in case you were thinking otherwise. All good 👍.
I have it disabled on my truck as well with tune, from 35,000km and currently at 210,000. Zero issues with this truck.
I'm in the same boat as you, if I need to open up the engine I'll get the Texa Speed delete kit and maybe cam.
I must have gotten lucky, my company bought a 2009 chevy 1500 with 14,000 miles on it back in 2011 and of course had afm. The truck made it to 247,000 miles and the #4 afm intake lifter failed. We have sinced changed all lifters on passenger side, and i bought the truck off of them. Now hearing noise from driver side lifters on start up, sometimes. Truck as of today now has 255,000. Must have been luck with the original lifters. 247,000 miles was a really good run. Currently getting all the parts ready to replace all 8 lifters of driver side, before they fail and cause more damage.
I am glad I kept my 03 all these years, instead of buying a new one. Still going strong.
I have never trusted cylinder deactivation. It was always a problem waiting to happen. When I ordered my 2022, I specifically chose not to have the auto start stop option (yes it is a Ford). My dream truck was always a GMC HD in my youth. I don’t take joy in these problems at all. Hope GM pulls their head out, for the sake of consumers everywhere.
I agree, first time I heard of this, I was thinking "this is a terrible idea that will make trouble in the engine". My non-Chevy is a Mercedes with Auto Start/Stop and ironically, it never does it. I don't know why, it has a battery as big as a small engine under the hood that is brand new. It just never does it. Fine with me. Thanks.
The DFM issue has nothing to do with cylinder deactivation though. It's the lifters.
Gms are junk if you want avoid truck get a Ford
Oops I mean get a Ford have had them no engine problems
All gm dummie engineers have to do is have the computer shut off the injectors on certain cylinders
Hay thanks. That was a very detailed video. I have a 14 and a 17 silverado. The 14 alway had a little tapping noise, but regular oil changes it keeps on going. The 17 so far so good. Already been researching delete kits out there. But for now ill just keep regular Maintenance and cross my fingers. Thanks great video.
Thanks for the video. Bought a 2017 Silverado & have started having these issues after 35k miles! 😖
They tell me its misfire but I know better. Thought it was fuel injector problems but thankful for this new info. 🤟
Ugh that sucks
Cool shout out to Chase in LMFSCREW. He has some good truck content. His Trail Boss is a nice one too
N nto umm n
Hey m
He's a cool dude. I have chatted with him a few times
Friend of mine owns a shop and he is constantly doing AFM deletes on customer vehicles. He keeps the kits on the shelf along with LS7 lifters and options of different camshafts depending on whatever the customer wants.
We’re is this shop located because I want to delet before problem starts
I just did the afm delete in mine. Mine is a 2013 Silverado though, 195,000 miles. I disabled it in the the computer a couple years but figured I’d change out all the hardware to give me a reason to do all the gaskets anyway given the miles I had.
Has he ever had issues with the coolant surging and causing a click in the thermostat after doing a cam and delete with tune? Having a random click that is not related to rpm and not consistent. Can find my post on Silverado Sierra forum
I owned a 2014 Camaro 2SS 6.2L with a manual 6 speed transmission, which like you stated did come without he AFM system. Never had a problem and it was a beast. So I decided in 2/2021 to buy a 2021 Chevy Silverado 1500 Trail Boss LT. I LOVE this truck but right at 24,000 miles, welcome the lifter issue. When I spoke with the service manager at Powers Swain dealership in Fayetteville NC , he did tell me that they would replace all the lifters since they had the truck in the shop already. I also had to take it back at about 12,000 miles for a transmission leak. The shop told me that the leak was due to "loose" transmission pan bolts on one of the corners of the pan. "They fixed it." At my last oil service I asked the mechanic to let me look under the truck while it was on the lift. Needless to say the transmission fluid leak was still there, and it did not look like it was from the pan, it looked like one of the rear seals on the transmission was leaking and dripping which during driving, the fluid could be blown all over. I am two weeks and a payment without my truck and the hold up seems to be a back order on head gaskets. And I wait.
Dynamic fuel management didn't start full production until late 2020. Also, it doesn't matter if you disable the AFM/DFM systemS the parts are still moving and can till fail.
I have replaced lifters and pushrods on 2021 5.3L with the system disabled from the factory(RPO YK9) due to lack of microprocessor.
Just finished a lifter job today on a 2021 Silverado RST. We disassembled a new and old lifter and the new lifters have different locks and a heavier spring.
Not sure about the USA but here in Canada we have a bulletin out right now to replace ALL lifters on BOTH banks if even just one lifter fails.
Is the issue resolved on 2022 and newer models?
I was told by a GM tech that a disabler that you plug into the OBD 2 port (I use one on my V6 Blazer) does help (he has seen them help first hand) the lifters last longer, but you are right they can still eventually fail at some point since they’re still in the engine.
Personally my thoughts are I bought a V8. If I wanted my v8 to be a 4 cylinder I would have bought a 4 cylinder. Granted I’m antiquated in my thinking and still haven’t been convinced that a 1966 Chevy Belair is any worse than a 2022 Chevy Silverado. I see almost no benefits to these new vehicles given they have issues around the same mileage as an old carbureted v8. In fact my 94 Silverado had 400,000 miles before I rebuilt it knowing it didn’t actually need the rebuild but I was there and fixing another issue so why not
If you saw a crash test of an Impala vs an accord sized car ... The dummy in the Impala was so destroyed.
@@cuencaview8303 actually I did see that crash test however I’m im talking about not being convinced that a newer vehicle is any better than an old one I’m not exactly looking at the safety factor. I’m well aware in my 66 Belair I’ve got what is basically a spear pointed right at my chest along with a very solid dash with basically no padding. I’m talking from the perspective of longterm cost and drivability. In another 50 years today’s modern car likely won’t be on the road because there is a whole lot to go wrong.
The issue is that people who need a truck are likely the smaller group compared to people who WANT a truck.
Keep in mind this kind of focus on fuel efficiency over reliability arose from the post 9/11 world where gasoline first bounced around 4$/gal.
So auto makers were designing trucks for COMMUTERS who are too fat to fit comfortably in a sedan (cuz this is america) rather than tradesman and workers who know reliability and repairability are more important than finding how much metal you can turn into plaatic to shave a few pounds off etc.
And commuters care about gas prices. It's seriously so annoying btw just get an ebike to cut back on fuel dependency then you can drive your truck when needed.
They make a displacement on demand delete that gets rid of the issue with that, and a afm bypass and gets rid of all these issues cost is about 900-1000
@@oculophilia8724 Fuel efficiency has been in the cross hairs long before 911,Americans have been buying Honda and Toyota since the 70’s because of there fuel efficiency
This was the biggest reason I decided to go with the 4.8 when I bought my 2010 GMC.
Das some nice rides Hawaiian!! been having lot of problems with my 2019 Silverado also and hear a lot of people in da isles jumping on some lawsuit. Hope they wins can fix mah truck asap! Ok Hawaiian take care Aloha.
Well heck, the Lawsuit should also include GM trucks from 2008 onward! Not to mention the faulty Transmissions & AC systems, which also has to be addressed.
The condensers with the shitty welds 🤦♂
Odd this popped up while I’m getting my oil changed in my 21 Silverado with the 6.2. Knock on wood no issues with mine.
Thanks for the info
We have a 2017 GMC YUKON XL SLT and just had this exact problem and surprise surprise the dealership only replaced one side. After reading about this and watching all the videos I’m counting the miles until we have to replace the other side.
Thank you for letting me know about this! I have a 2019 Silverado.
I feel somewhat protected against these failures since disabling the DFM with the PulsarLT, and also stopping all that crud from re-entering the engine thanks to the catch can....and of course I would not have done any of this had I not stumbled upon your channel. Great content, keep it up, my 2019 Silverado 1500 LT thanks you as do I, especially since it now only has 9mos of factory warranty left on it.
I HAVE THE JLT 3.0, AND I LIVE IN CALIFORNIA WHERE THIS MOD IS ILLEGAL, WHY THIS IS, I HAVE NO IDEA.
MY CATCH CAN CATCHES 3.0 OUNCES EVERY 6000 PLUS MILES. SO I GUESS EVERY FEW YEARS ONCE I HAVE TO START GETTING IT SMOGGED I WILL HAVE TO REMOVE IT.
@Jim jibroni I just re read my previous comment. Yes I will be re-installing the JLT as soon as the smog check is completed. I'm hoping JLT will get the CARB approved for California, this unit is a no brainer and the catch can proves it. 2.5 ounces every 6000 miles. I will be installing the PULSAR LT next month. It will be nice to have a full time V-8 and not a V-2 or even a 1 cylinder engine at times.
Don't be so confident, disabling will not stop the internals from coming apart. It just won't go into that mode but you till have a ticking time bomb under the hood.
Loved the video! GM really needs to get it together. I have a 2021 that has had 2 lifter failures and 2stuck injectors within the 1 year of my owning the truck. The worst part about it is I have always been about 1000 miles from home when it decides to take a crap on me.

Aloha and mahalo for this video bro, glad I saw this because I’m in the process of buying a Chevy Silverado 1500 6.2 trailboss and had no idea about this, till now. So again, mahalo!
I can relate to this madness, lifters have failed multiple times eventually wiping the cam and toasting the motor. My only saving grace was having an extended warranty which eventually replaced my motor after spending 7 months at the dealer.Repairs have totaled to almost 20k, i was a die hard Chevy and GM guy. I’m getting rid of this headache 😕.
That blows I’m praying my 2021 has no issues
We need to boycott for two years and force them to do better. They build beautiful vehicles with faulty parts and technology.
Quitter
This is why I left.
Dealing with it now
Coming from a huge GM fan….GM needs to get their crap together and FIX THIS ISSUE! Not to mention the 8 speed transmission shutter that my 2017 Yukon Denali had. I did buy it used so I had no warranty. Luckily I have a good friend who is a GM mechanic and he flushed the system and put in the new revised fluid. But my last 2010 Sierra had the lifter issue around 90k miles and I deleted all that crap and had the ECU reprogrammed.
Great video. Our 2017 Yukon Denali (6.2) has lifter/pushrod failure. It only has 73,000 miles on it.
Im surprised this lawsuit only goes as far back as 2014 when in reality AFM goes back much further. I had lifted failure on my 2008 that cost a boat load of money to fix and ultimately the repair only lasted a year as the mechanic shop only replaced the one bad lifter. As it turned with some research I found that there were also two recalls, one to upsize the screen on the oil pressure sending unit and one for Lifter Oil Manifold Assembly itself. I decided to do the repair myself this time, and I mean repair the whole thing since the mechanic shop sucked so bad. But really it comes down the the AFM being such a garbage system that should have been discontinued years ago. After I fixed my 6.0 and I found the module to plug into the OBD2 port to bypass and never use that pile of crap system again. I only wish I could reimbursed for the 1000s of dollars I put into my 08 silverado
That's because Gm won that class action years ago.
do you have any more info on the recalls? my 2012 silverado just starting the fluttering today at 1000-1500 RPM is my valvetrain shot or can i switch to this other drive mode to save my engine from blowing up? please help me im very stressed out any more info on this drive mode would be much appreciated
@Noname23489 any updates??
I think I'm going to be getting mine deleted on my '08 Silverado this summer hopefully. I've got it turned off for now with my Bullydog GT. But I think I'm going to finally pull the trigger on it and get better internals as well, forged, better cam, lifters, etc.
Ps. Thanks for the great video and info as always! Your awesome. Love the videos, keep it up!
@Jim jibroni still a lot cheaper than buying a new one with all the issues I've heard. And I've been planning awhile to do this. Also depends on all that you want to do besides just deleting it too. Making what you got even stronger/ better.
I would delete it ASAP!! I bought my 08 5.3 crew cab brand new in March 08 and my lifters start going bad at 100k or so my friend replace all of them and re did my heads just in case and deleted that stupid fuel management shyt… I can’t believe these new ones are having even more problems. GM needs to get their shyt together not acceptable at all smh 🤦🏻♂️
Hi there,
I came around to your channel and let me say you are a smart guy how you communicate these issues ⚠️ from GM
Unfortunately, hopefully, it will get resolved soon.
Appreciation your blog.
Got the 2007 6.2 yukon denali at about 200k miles and still rockin! Enjoying that i have no Afm/dod built-in to mess up my engine.
Thank you brother!!! Very Informative clip
Our '21 Silverado with the DFM L84 5.3 had the lifters fail at 585 miles. This happened almost exactly a year ago prior to the updated TSB guidance so they only replaced the damaged lifters on cylinders #6 and #8. I really hope this class action results in a recall with upgraded parts for current owners. I only drive the truck in L7 (8-speed transmission) to disable DFM and I still can get 20 MPG cruising on the highway without DFM in 7th gear. If I had known this was going to happen, though, I never would have bought the truck and really regret not going for the 6.6 gas 3/4 ton instead.
Did you drive in L7 before the lifters failed?
@@ryantinney No, I was only using D for normal driving when the failure happened. The check engine light flashed intermittently on four occasions when a lifter would stick. Post-repair I exclusively drive in L7 for normal driving and I've always reflexively shut off auto start/stop from day one.
GM is sending many of the new ones to the dealers and fixed before they sell them. My understanding is that it's not only the lifters getting replaced but the camshaft as well
Hope ya truck gets fixed. Hopefully mines doesn’t break, I have a 2020 LT 5.3 with 24k and it runs rock solid. This DFM/AFM stuff needs to stay out of cars and trucks. Trucks always get bad gas mileage anyways so there’s no point in improving it…
Jesus that’s horrible
They need to do this from 07-13 as well
Hell yeah, my ‘09 silverado with a 5.3 failed at 90,000mi and chevy refused to cover it because it was 10 years after build date on it… smh.
There was one for oil consumption and Gm won. Also won the suit for 07-13 dash cracking.
My 2013 had a lifter collapse at like 140k luckily it was under warranty still so they got to replace it all and then it had an oil consumption problem
My 09 Silverado failed at 85,000 miles. GM covered it. At 150,000 miles zero oil pressure 24 miles from home. I floored it at the high speed # of (as u know well) 100 mph. Don’t know how it made it,but it got me home. The engine was shot to hell. Got a 2020 trail boss 6.2 slammed a (don’t buy this) supercharger. At 7,000 miles, blew a rear main seal and I so hot because When I’m done the 6.2 will have 8fiddy hp. GM’s fault😂😂😂😂
I got a 04 5.3 hands down absolutely no issue with it. 250 thousand miles on it still pulls my boat strong every year in a side-by-side. It's just like all these newer vehicles of trash.
Hopefully there will be a class action suit against GM for defective paint! The (silver) paint on my 2015 Silverado is flaking off like crazy. Inskeep hearing others with complaints about GM paint as well.
I will keep hoping and praying and you keep on making awesome vids bro!
Keep hoping, prayer doesn't work at all.
And the piece of crap 8sp transmission. already has a class action on it.
Sadly that issue is why I sold my Silverado it was my first truck and I loved it. Couldn’t trust it anymore, but I’m very happy with my new Tundra :)

This issue goes back a lot further than 2014!. In 2010 I bought a 08 sierra 4wd 4dr loaded w 21k on it, by the time it had 150k I spent $8,000 on AFM lifters 3 times and a rearend, I sold it with 2 collapsed lifters in 2014 never to buy a gm truck again till they fixed that issue.
I agree. Just spent 3000.00 on my 2009 Tahoe LTZ. I had a lifter failure. While the mechanic had it in he deleted the AFM.
CADILLAC HAD A SIMILAR PROBLEM IN THE 80"S AND DID THE SAME THEY SHOULD HAVE LEARNED FROM THIS
I just got through paying 4 grand for the lifter failure in my 2018 GMC Denali. I am a life long GM fan, but this has me looking at other brands moving forward. Also, my 2014 GMC SLT also had the same failure, fortunately the factory warranty covered that one.

I have a 2014 Silverado 159k miles two lifter ticks but hasn’t taken out my camshaft or anything so I guess I’m lucky no loss in power either

@@jackwillie2729 - Who would even think of going Ram?
This needs to extend to all models. Depending on severity it can cost thousands to repair. I did a quick repair on my 2010 in the driveway. Just one side, cost $600 and took 8 hours to do

Your lucky !!!!! Cause I think and know a Toyota or ? will out last these 5.3 litter engines by lasting twice as long ......Chevy should make a truck to last and quit making cheap ass inferior parts
Love my 08 Silverado, has AFM as well. You have to know why our cars and trucks have this in the first place and then you'll understand the big picture. The government has regulations on minimum mpg standards and this is one of the manufacturers answers to achieving them. Too many government regulations is where this all stems from.
Have you heard what Biden wants for the new fuel regulations to be now. I’m not 100% sure but it’s around 45 mpg in the future. He’s trying to get everything to go electric. But our electric grid can’t hold up if everyone plugs in now. Jmo

Yup you are correct
The government didn’t tell GM to not support warranty claims and not to fix the problems. Nor did the government tell GM to place a poorly thought out DOD system with reliability issues on millions of vehicles. GM is trying to bury the problem just as they did with the 6 spd auto problem. Don’t blame the government. Your continued support of GM by buying defective by design trucks makes it your fault too.

Interesting video! I have a 2019 5.3 silverado. This happened to me in July. Had the truck in for a torque converter warranty issue. Got the truck back 24 hrs later drove 8 miles and home had major top end noise called dealership and they recommended roadside assistance and brought it back to dealer. Failed lifter number 5 cyl. Dealer replaced only number 5 notified truck not running right on number 5. Diagnosed cam issue and replaced under warranty. Waited 7 weeks for head gasket (global shortage) Fortunately GM Canada provided me with a silverado rental covered by them at a cost of $4250 for rental. Got truck back and now left with no confidence! I hope there will be a class action here in Canada as well. This is the 4th new truck since 2014 Not sure what to buy next. My warranty was up at Christmas. This is BS a lot of money for something unreliable .
My brother-in-law had the same issue outlined in the class action with his 2021 Trail Boss. Push rod got bent on one side so they fixed that side, some time later, same issue, on the other side. They gave him a lifetime warranty on the truck for the trouble.
Just found this video it’s going through the same issue right now with cylinder number four. On my 18 Silverado 5.3 70,000 miles up till now no issues. Hope it gets taken care of.
Hey man thanks for the heads up. My wife and I went yesterday to look at a 2017 black Silverado Black widow addition. As we were driving it we felt the slightest vibration at a stop. We asked them to check this out and when we got home I watched this video. Today we received a call from the dealership that this vibration was this very issue.
This will be a NO BUY for us. This ment a lot because we have never owned a Chevy, always Fords but this truck looked like yours, just damn mean... We loved it but thanks again man, you saved us some major headaches.
I recommend not to buy a black widow truck they have a laundry list of issues from the cheap lift kits they use. Buy a stock truck and have a off-road shop work with you on a good lift kit.
@@nick183ful Thanks for the tip.
I was always a Ford guy myself...until I bought my brand new F150 with the 5.0L in 2014. I knew there was an issue within the first 25k of owning the truck, I asked Ford on 10 separate occasions to look into the issue for me...they never did properly. Long story short, after 120k, and past my warranty, I was told I would need to replace the engine...the issue was EXACTLY what I told them I thought it was years earlier. Absolutely horrible experience with Ford, left a BAD taste in my mouth. I will never, EVER, buy another Ford ever again. *$&! Ford.
@@jerrybuck9236 i feel ya brother. I have been lucky with my Ford. The story behind my truck is in 1997 my wife and I went to buy a Torinado Red 97 F 150 4x4 extended cab off road package. Once we got there a white F 150 Lariet 4x4 drove off the truck and we bought it instead and my father bought the red one. In 2016 my father passed and we still ended up with the original truck.
In 2016 the truck had 61,000 miles and everything was still original down to the 4.6 V8. Now it has 87,000 miles, still all original with new tires. The truck is flawless and runs like a top.
We are blessed to have a vehicle this good because it ain't the norm by no way. Every make, model from all three are more than likely nowhere near dependable as mine and that's a shame.
You basically have to buy a $100k truck and put another $20 k in after market parts to have a dependable vehicle. It's like the Jeep Wrangler. They aren't bought great, the are built great after bought. It should really be criminal.

When I bought my 2018 5.3 Silverado in August of 2018 I thought the AFM is the coolest thing ever, best of both worlds! I drove the truck in D for its first 15k miles As I watched more videos and read more forum discussions I made the decision to drive the truck exclusively in L5. My 30 mile commute is all So Cal stop and go surface streets. Hopefully this decision will prolong the life of my trucks lifters. 31.5k miles and counting.

I bought 2009 Pontiac G8 GT sedan, brand new, in Baltimore, MD. It came equipped with the L76, 6.0 L, V-8 engine with AFM. I never had an issue with the AFM while I owned the car (I traded it in 2012). I’m sorry to see the class action suit come about for 2012 and newer engines.
Yep. 2016 Yukon Denali 74,000 miles just experienced failed AFM valve lifter. Mainly all highway miles, we don’t drive in harsh conditions, make all service intervals, and we don’t tow and still had one fail. Several thousand dollars to get it fixed. Ridiculous that GM has failed to acknowledge this issue and leaving owners stuck with astronomical bills to have a drivable vehicle again.
$5000 for ONE lifter on my 2016 gmc sierra 1500 6.2. An absolute rip off. GM should face up to the sheer number of customers that are having to deal with this s*** all the time loss and huge dent on your wallet. Not fair. Hoping for a recall
14 Silverado 5.3 140,000 miles. Runs perfect. I had a new dodge with issues before this and they wouldn’t help for shit. GM has been very good to me at least.

They need to extend this to the 2007+. I have a 2008 and the same thing happened. I tore into the engine, and discovered that whoever had the truck prior to me had the same exact problem. So I tore it apart took out the stock lifters, put in LS1 lifters and a new camshaft, and had the computer sent and wiped. It has been running like a champ ever since!

I’m a GM Dealership Heavy line technician…. The lowest amount of miles I’ve seen lifter failure on is a 2021 Escalade and it had 800 miles… the bulletin for the lifter failure stated replace all 16 lifters if it was under “8000 mile break in period “ and if had more than 8000 then it’s only one bank…

@@Motagraphy it’s about at least one a day sometimes more… and then they’ll sit because lifters and stuff will be on National back order.

Thanks you for this valuable info. Sadly we have all known about this issue for a long time. I bought a default module as well. It plugs into my OBD port. So, I can take it on and off depending on servicing. Hopefully GM will now be FORCED to step up. All makes have their issues. In the end it’s not the issue as much as it is about how the companies handle these issues. So far GM is an epic fail. So, now we wait for the courts to decide. From a business standpoint, I get it. From a consumer and loyal customer, sorry, I don’t get it. GM knows about the problem and has known but still says, denied.
I did the same with my 2019 Silverado LD. I have 52K miles with no issues, probably thanks to the OBD module that deactivates the 4 cylinder mode.
@@bigtenbrutus it might deactivate it. But the mechanical portion of the lifter can and will still fail. Only fix is to delete it all togather.
My 2016 Yukon Denali 6.2L engine *cratered* due to these issues. Had to replace the entire engine -- and of course, due to 'supply chain' issues, I had to source a *_used_* engine from ebay. Lovely.
When Cadillac advertised the 4-6-8 L-62 engine on TV, I remember watching and said to myself, not going to work.
It lasted one year.
Honesty and integrity always gets in the way of profitability...
Literally dealing with this issues right now on my 2015 Z71 6.2L, lifter #7 blew while my transmission was being replaced during the test drive from transmission shop. Really makes me wonder if my transmission was even an issue, might wait to see what happens with this before replacing (not gonna drive it) Hope a recall happens soon.
The 8 speed GM truck trannys are very problematic too. We at my dealership had 9 of them we were waiting on the warranty department to get GM to pay off
Thank you very much. I went and posted it to Facebook and Twitter to let everybody know
GM had to replace my camshaft and lifters and associated parts, one day before the 5 year warranty ran out on my 2009 Silverado. Lucky me! The mechanic told me that he put in LS7 lifters. Anyway no problems 8 years later.
I live in the Middle East and my daily driver is a 2013 Tahoe which is with me since new. Its lifters have failed twice in a span of 158000 miles out of which one replacement was under warranty the second one I paid for. The problem is there is too much truck to just let go just because of a lifter failure and I have decided to keep the truck until the next lifter failure happens. Much cheaper to get it fixed than get a new truck in these uncertain times that we live in, in my opinion.
I own a 2014 Sierra that has a constant ticking noise and always has. I questioned this during my warranty period and it was checked out. I was told that what I was hearing was normal and is consistent with other GMC trucks. I told them to record the fact that I had questioned this issue for future reference. I currently have 66k miles on it and it seems to run fine other then using a bit of oil. Generally about a quart between oil changes.
My 2014 Sierra did the same thing, never gave out though. The transmission on the other hand started to give me some issues.
My 2000 I still drive goes through that much and it had 300k on it
Very close to subscribing. This is great info. I really want a 2019 Silverado, but I may have to get the 4 Runner:/
Learned about AFM shortly AFTER I bought my 15 sierra. Luckily the warranty I purchased with it will cover it.
My 07 avalanche has the afm system in which I had lifter failure costing me a large sum of money I feel the recall should go back as far as these systems have been installed in there vehicles pertaining to the mentioned motor sizes .
GM which is my favorite brand did the active fuel management back in the 1980s and had the same problem, GM got rid of the motors and went back to regular engines. I have no ideas as to why the tech came back. My dad who is a huge Cadillac fan wouldn’t buy a newer Cadillac when this tech was on their cars. He always said to never buy the car with that motor.
They had to bring it back because of the epa putting regulations on trucks to get higher gas mileage by 2030. I can’t remember if it was 30 or 40mpg average that manufactures have to achieve but now they’re having to neuter trucks to appease these regulations.
Oh man the Northstar haha. My grandfather had one of those Caddys too and as a kid all I remember was it was constantly in a shop. He never bought a Cadillac again after that

I had hired a lemon law lawyer about 3 months ago and my hearing is in the month of April. Trying to get a full buy back or a cash pay-out that I'm hoping will be the cost of a new engine if and when the engine needs to be replaced.

They replaced just the lifter that was damaged and gave it back to me. 9350 another failure and they replaced the bank of lifters on the other side. So, I still have 3 more potential lifter failures heading my way. The dealer stated they were not authorized to replace all the lifters when I mentioned the TSB on my first go-around with this crap. Here are the other issues with my new truck : new drive shaft is on back order since the summer. It makes a loud ping/ting sound under load or shifting load from forward to reverse. They said it’s a drive shaft. I am also now having Electrical issues ever since the first lifter problem. My 4WD fails even if I’m not in 4WD or want to be. Just a light that pops on along with rear park assist off light. Check engine light has happened with these codes and the dealer can’t replicate or find any loose wiring to fix. The codes stored and active are starter A and starter B failure. Communication failure from the ECU, loss of communication to the radio. CAN bus problems and low voltage. I have not changed any of the incandescent lights to LED either. I hate my truck. I have asked the dealership service manager to call me tomorrow and see about them buying the POS back from me.

@@HowtowithPaulHenderson thanks man!
I am a firm believer in frequent oil changes to help REDUCE the chance of failure. Small holes in lifters can clog and prevent oil flow. Yes some will fail no matter what. I change my oil every 3k miles and use AMSOIL engine flush every third change. I also turned that system off through a tuner. Now have 45k miles. No issues yet
My son has an '09 Silverado with the 5.3. We have installed the AFM delete tuner and we change the oil every 3K miles as well. He currently has 119K miles on the truck and, knock on wood, it still runs strong with no knocks.
Change mine at every 3 k. Didnt help at all
Local police department bought a new 2021 Tahoe, ran 1500 miles, failed lifter. It didnt even make it to the first oil change. Replaced only the failed side under warranty, not both sides.
Have a 2013 with a 5.3 turned that shit off at 19k currently have 111k and Running great
Synthetic is key. It's so cheap nowadays there's no excuse to use conventional dino oil.
Good ol Chivy, it’s all about the dealer experience, where you’ll no doubt spend a lot of time.
Yes!! it was happy in the 2007 5.3s as well..
Thanks for posting this. First I've heard about it. I've got a 2015 Silverado with the 5.3L. Ticking noise from the engine since the first day. Luckily, no disasters yet, but I've only got 17k miles on it at this point. Repeated complaints to the dealer were always explained away as 'that's normal" or "it'll go away after break-in", but basically just saying "fuck off". As a side note, I was getting 14/15 mph city, until they did a transfer case software update about a year after I bought the truck. Since then, it's been 7 - 8 mph city. More complaints, more bullshit excuses.
My rods and lifters went in my 2020 trailboss. Traded it in as soon as I got it back for a 2021 ranger. Best decision I ever made. I’ll never buy another GM product
If the ticking is up top it may be the injectors. The high pressure fuel rails will do that - very common in vettes.
Lol yeah after 36,000 miles it will start burning oil a quart every 800 miles dealership said that’s normal also when it leaves you on the side of the road they will tell you that’s normal also 😂
@@anthonymakley1530 wow glad I got rid of mine. I used to have a 2011 focus with 190k miles and it didn’t burn a drop of oil. It pisses me off more that dealerships try to tell you it’s normal.

Most of the time I have a knock up top. Sometimes it does not knock. I am going to take it to the GM house this week to see what they say. Btw 97k miles
Thanks for doing this video on this CA Lawsuit. Keep us informed. Just curious, do you use a full synthetic engine oil in your Silverado truck and how often to do you change your oil? Did the CA Lawsuit mention anything about engine oil type that may have impacted failures? Also, I had the same smile on my face as you did, back in 1977 when i removed my BBQ grills (same as your truck) from my 1977 Trans Am and put Glass Pac exhausts on to give it an awesome sound.
No the oil doesn’t matter. My 2020 trailboss, oil changed at 2k miles, then just before 6k. Rods and lifters went at 8k. They’re making junk engines. I traded it in for a 2021 ranger as soon as I got it back. I’ll never give GM another penny. When you spend $60k on a truck you expect it to last longer than 6 months
For the 07-18 trucks if you aren’t consistent with oil changes even by a little bit that’s how these lifter issues start. Always change the oil every 5k with a full synthetic. Every time someone goes over or starts to neglect their truck is when they start complaining about the issues. For some reason these trucks just can’t handle long oil change intervals well. 2019+ trucks are a totally different story. They’re awful, that’s just terrible workmanship and quality.
@@UntamedOutdoorsmen I’m not saying you’re wrong, but they also just built them wrong. Mine blew up at 8k miles and I had already done 2 oil changes with Mobil 1 full synthetic. Sure some people neglect them, but GM also made them like junk.
@@lesterparker1594 yeah I agree with you I had an 09 sierra did very tedious maintenance and never ran into a singular issue regarding lifters. Doing the same thing on my 2014, afm disabled, less miles and has lifter clatter and noise just like the rest of them. 14-18 aren’t bad trucks but they’re definitely worse then 07-13. 2019+ have reached a new level of awful and bad quality. Nothing you can do to prevent the issues you had.
Chevrolet knew about this since 07 with the AFMs
I have a 2018 Camaro SS automatic with the LT1. I have AFM on it and it works. It switches from V8 to V4 mode and I don’t always notice the switch. I bought mine used with 35k on it in March 2022. So in 6 months I’ve put 10,000 miles on it and haven’t had any issue with AFM or the 8 speed automatic which it seems a lot of people also have issues with. I’m bringing it to Chevrolet in a couple weeks for a trans flush and diff fluid flush and oil change but not because there’s a problem. The owner’s manual says to change all those things at 45k which is where I’m at now.
I had the same thing happen to my 2020 GMC Sierra 1500 X31 Elevation… the dealer had my truck for about 45 days before I got it back. Needless to say, I traded it in soon as I got it back.
The thing I don't understand about big companies and this isn't just limited to automakers but large companies in general; is that they know of these issues pretty quickly after they are discovered. Whether that is through the owners of the vehicles or through their own internal testing. Instead of admitting mea culpa, they would rather sweep it under the rug and kick the can down the road until the wind pushes it back and hits them in the face via a class action lawsuit. I'll never understand this mindset, ever.
Same here but it’s about money. They were probably hoping the failure rates would be low and took a gamble. Rather then pay for all engines with the defect design. If they lose this lawsuit they will probably take another gamble and just extend warranty based on time or mileage instead of recalling the engines and/or transmission, a lot of car companies do this.
How much off these trucks are already totaled? $$$ Saved.
They should think about the long term if they don’t want to go bankrupt again.
Generally speaking, say a car company has a defective part on every car that will break within a few years. The corporate question is, will it cost more to replace the parts under a recall, or will the inevitable lawsuit cost more?
Most of the time if the fault is drivetrain or electronic related, the company will gamble with lawyers. If it is a safety concern - i.e. seat belt/air bag/ brakes they will recall the parts, cause the lawsuits would definately be costlier than the recall.
Its pretty shitty, but thats how most companies(at least large ones) operate, purely financial...
Because they figure it's lest costly to fix the issue, when it happens under warranty and then the consumer will pay for it after the warranty expires. So, in essence, they are saving money by NOT replacing them all in a recall at one time.
You also have to understand they are required to equip the AFM to meet CAFE and emissions standards. Otherwise they would be required, and likely will in the near future, smaller displacement engines with turbos or superchargers.
I do t know about current standards but I believe at one time the only v8 engines that could not have AFM and VVT were commercial. But that may have changed.
What a shame been a year since this post and still nothing
I have a Ford F-250 with a 6.2 liter engine and still going strong at 375000 miles amazing truck one of my best investments.
My 2021 GMC Sierra 1500 had this problem at 5,300 miles. The dealer fixed it under warranty, but when I asked the service advisor how often he sees this problem, his response was, "Way more than we should." I purchased a Range Disabler to shut off the DFM system, and it seemed to work fine after that time, but I didn't trust a vehicle that needed an engine rebuild after so few miles. I traded it in and got an Acadia instead.
