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!!

[@braedenboss5636]

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 KZbin, build a more reliable 5.3 than one of the biggest car manufacturers in the world?

[@britknowles6530]

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.

[@roywall8169]

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.

[@BrisLS1]

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.

[@PlayWaves1]

The DFM issue has nothing to do with cylinder deactivation though. It's the lifters.

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. 🤘

[@noahkb80]

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.

[@andrewsbbq]

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.

[@armandohernandez1412]

@@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.

[@andrewsbbq]

@@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.

[@Crozier4582]

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.

[@redneckwithajeep5001]

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

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.

[@oculophilia8724]

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.

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.

[@MrDutch1e]

Is the issue resolved on 2022 and newer models?

[@DJAJ101]

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.

[@markgoff3367]

I own a 2015 Silverado. Several years around this time are notorius for numerous repeat transmission problems. GM should be responsible for fixing these problems, NOT the consumer

[@zlamont3939]

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

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.

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.

[@chriscole2110]

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.

I live in the Middle East and my daily driver is a 2013 Tahoe which is with me since new.

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.

[@KyRipsnorter]

I own 2015 Silverado 5.3. Had the lifter failure at 248,390 miles. That's right, I got 248,390 miles before lifter failed. I took the engine out myself and deleted the AFM system. Replaced all of the lifters with LS7 lifters, and ordered a HP Tuners unit and shut off the AFM at the computer. I reinstalled the engine and it runs like a dream. Best mileage so far has been 24.6 mpg. I regularly get 20-22 mpg. It has the six speed tranny. Yes, I love my truck, but I do not love the AFM system. It nearly destroyed GM when they developed it back in 1981. BTW I think they need to junk the AFM system along with MARY BARRA. BTW #2 If you get the HP Tuners unit, you can retune the transmission lockup that causes the torque converter failure. You see, GM has the torque converter going into lockup AT 11 MPH!!! You can disable that function for the first, second and third gears and not stress your tranny. While you are at it you should remove the thermostat for the transmission fluid. That thermostat opens up at 194 degrees (to save about 1/10 mpg of gas!) but it destroys the tranny. Just take it out altogether and enjoy your truck!

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.

Sad part is when you delete this system with aftermarket parts and have the vehicle tuned by someone that knows what they are doing the vehicle will get better fuel mileage running on all 8 cylinders all the time

[@edgarisaac668]

Yup but it will void your warranty

[@bcar1ify]

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

[@kentuckyhiker7071]

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.

Synthetic is key. It's so cheap nowadays there's no excuse to use conventional dino oil.

[@HedgeMaster26]

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.

[@elvism684]

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.

[@hebson21]

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...

[@williamguillIII]

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.

[@shawnhicks619]

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.

[@hugieflhr03]

I’m a diehard GM owner and personally I believe it’s the weasel piss oil GM is recommending for these high performance engines running at 220 degrees. Soon GM will be recommending 0 w10 oil just to save .00008 mpg

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. This really pisses me off because they new of the problem years ago and like you said did nothing. Maybe if enough people sue them and win, they might think twice about not correcting a problem with an engine design flaw once it is brought to there attention.

I wonder if I should try the same thing as you - - - “I’m in a similar boat to the one you referenced in the lawsuit. 2021 5.3 LT Trail Manager. 7250 miles was my first lifter issue. 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. I have yet to trip 10k miles on it because it’s in the shop all the time. And I only got a rental/loaner once from them. What a nightmare. A $60,000 nightmare. Thanks for sharing.

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 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 paid my truck off 12-21-21. My truck went into a limp mode and would not go on 12-23-21 so I took my 2015 GMC sierra 1500 truck to get it fixed on 12-30-21. The #1 cylinder was misfiring the camshaft was found to be bad from CMC Automotive in Langley SC. When I found out the repair cost was going to be $7500 I called around to get other prices. Found that where I bought my truck from in 2015 from Johnson motors in Aiken SC could do the repairs for $4000 + or - $200. It took several weeks for them to get parts to fix it. I got my truck back on 1-19-2022. Drove it until 2-14-2022 and it did the same thing. They repaired it. I got it back 3-11-2022. Drove it until the same thing happened again on 3-18-22. Took it back to get it repaired and they couldn’t fix it after having it for two weeks. So GM said they were going to put me a new 5.3 engine in it. Every since 4-19-22 I have been waiting for it. Every week I get a no ETA. I have been without my truck pretty much since 12-30-21. Is there an attorney I can talk to about this matter?
