Chevy 1500 5.3L V8 Lifter FAILURES (Active Fuel Management) **Heavy Mechanic Review**

[@donjohnson2428]

I’ve been prepared to buy a 5.3 Silverado for almost a year now but afraid to pull the trigger because of the lifter issues. Frankly it’s absurd to have to worry about this when you’re spending nearly 60k on a new truck. GM needs to do better.

[@TDub_ADV]

At this point get either the 2.7 I4 or the 3.0 Duramax. Either v8 are basically a failure in waiting, not if but when...... I personally have had lifter failures on 3 6.2l engines. If it were me buying a GM 1/2 ton it would be the 3.0 all the day long. Its probably the best engine option they make at the moment in a 1/2 ton.

[@AmericanConglomerate]

go for the 7.3 godzilla from ford, I've had mine for 2 years, put 53k miles on it. runs like a champ

[@EBIndy]

The 2.7 Turbo is a joke. Its a gas guzzler and lacks capability. The 3.0 Duramax is THE Engine to get.

[@2003evodave]

Time to stop buying “general mess” problems. I had a fleet of Chevy heavy duty and light trucks, cars and race cars for decades with nothing but endless troubles. Finally had to give up and went to Ford and Ram vehicles. Love my Raptor and all the gas Fords trucks plus my 5.0 GT Mustang but can’t afford even at fleet prices Ford diesel trucks so bought Ram Cummins 3/4 and HD one tons. We do logging, land clearing, general excavation, demolition and construction. We are meticulous and always are early on all maintenance and never had a single major failure except with GM products including total explosive engine failure, countless transmissions, numerous transfer cases, rear and front axles, couldn’t count all the drive lines (front and rear), electric problems (IE windshield wipers, power windows, Radios, heat and AC) paint falling off, rust, brakes are all the major issues. I am not saying we never have a issue with other brands it is just that they are all so minor it’s not worth mentioning.

It's truly unfortunate for the people who are having the issues that GM is screwing them over.

[@GettysGarage]

Seems like it unfortunately

[@hochhaul]

GM isn't screwing anyone over. The lifter wasn't "updated". In the last 1 or 2 years, the supplier of the springs inside the lifters was shipping product that was outside of the tolerance range specified by GM. That caused lifter issues at higher rates than in the past. It's hilarious hearing the narrative be revised as lifter issues actually began to be a real concern on 2021-23 trucks. The same rhetoric was used when the 2014--19 trucks were being buillt and sold, yet there are a ton of those trucks with 200k+ miles without an AFM lifter failure. The primary difference was how often the oil was changed. Tundras have engines with crank bearing failures left and right, Ford is putting rubber belts on all their oil pumps, and Ram has had issues with 5.7's grinding lobes off cams for over a decade and none that gets used in a FUD video.

[@mnieliw]

​@@hochhaulwhat in God's name are you taking about? These lifters are failing on cars with cars with 50k miles and GMC isn't helping with repairs. 9k to fix.

[@hochhaul]

@@mnieliw BS. A bad lifter at 50k miles they would be covered under warranty. There is definitely a LOT more to that story if there was something that caused the warranty to be denied. GM sells over a million vehicles a year with these AFM/DFM engines. Internet clowns run their mouth about how those you won't go 100k miles without a bunch of lifters failing and that's BS. I know guys with 2014+ GM trucks that have never disabled AFM and a bunch have anywhere from 180k, to 230k miles on them without a single lifter problem. I know two guys that have had a bad lifter. One had a 2012 Silverado and they would wait until the oil life monitor said 0% to think about taking it in to change the oil. Oil sludge causes 90% of the lifter issues. The other was a guy with a 2022 GMC Sierra AT4 with the 6.2 that had a bad lifter at 20k miles and GM replaced ALL the lifters under warranty. Like I said, in just the last 2 oer 3 model years, yeah they had a spring supplier sending out of spec springs that go into the lifter assembly and that was causing a very significant number of lifter failures. But GM isn't denying warranties for bad lifters.

It took nearly 3 weeks to get the problem fixed, and they only replaced the lifters that went bad. In other words, this fix was more of a Band-Aid, since there were still seven, other cylinders that could go bad. I ended up selling the vehicle and buying an expedition

I have a 2017 Denali with the 5.3L with the 8 speed. Bought it in 2019 with 48,000km on it, bought a diablosport ITUNE 3 for it right away and disabled the AFM. As soon as I installed it, I got better fuel mileage and nearing 90,000km now (don’t drive it in the winter cause it would be rusted to heck by now since I’m in Ontario, Canada) no knocks or oil consumption issues yet lol. Plus I bought the Superior STL010 thermal bypass kit so the transmission runs cooler. When it’s +30 or higher outside the transmission runs at 60C instead of 95C, even when towing. So no burning out the torque converter (hopefully lol). Will definitely consider the 3.0 duramax truck, once my 2011 Impala LTZ with 320,000km finally dies lol. Good video as always dude!

[@austincloutier8688]

I honestly don’t doubt that, but you’ll hear more about the issues people have had with lifters than people who don’t. 2014 was the first year they switched to GDI motors (means nothing about the lifters) but it is the first year to that style motor. I know plenty of people who own 2016-2018 5.3 & 6.2 motors that have gone above 280,000km, my step brothers 2018 6.2 Denali has over 174,000km with no issues with lifters. AFM deleted or not.

No down hill engine brakes as well. It's always a full V8 in an always ON state. Only upgrade I applied was Timbren SES in its rear (due to its factory soft rear suspension and my heavy weight trailing towing).

I really like my truck and have always maintained it meticulously including changing oil/filter at 5000 miles with the correct grade full synthetic oil. If you simply listen to internet chatter, every single Chevy 5.3 will have this problem. At least I feel somewhat better that the actual failure rate is 2-3%. Not great but at least reassuring that I could own this truck for years and many miles with no issue. It's a gamble for sure.

as an old mechanic, I would use valvoline VR1 racing oil, as long as the truck is not burning oil it will not harm the catalytic converter but you will have no camshaft or lifter problems, other oils do not have much zinc in the additives, that is what protects your camshaft, it coats it with a high pressure coating, but will do the same to your converter if it is burning oil, making it non effective, I would still use it a converter is cheaper than a cam replacement

We have a '21 Silverado with the L84 5.3 that got its first flashing misfire check engine light at 585 miles. After the fourth check engine light, the dealer finally replaced the lifters on cylinders #6 and #8 only (this was prior to the 2022 updated TSB guidance; we should have had all 16 lifters replaced based on the TSB). On top of other issues the truck had (bed misalignment, inoperable rear HVAC vents, etc.), it was at the dealer for a combined 51 days over the first few months of ownership. The truck now has over 23,000 miles on it, but I always drive it in L7 (8-speed transmission) to disable DFM and I change the oil prior to hitting 50% on the oil life meter, which works out to roughly every 3,000 miles. It's a shame because the truck drives and tows/hauls pretty well overall, though the 8-speed can be rough when cold and the valvetrain is horrible. We also had to have the serpentine belt and idler pulley replaced around 6,000 miles because it's a one-time use stretch fit belt that they reused after the engine teardown. If we get another gas powered GM half ton truck, I honestly would get the 2.7 Turbomax as the testimonials from actual long term owners seem overwhelmingly positive in comparison for the 5.3/6.2 and the performance is comparable to the 5.3.

[@jimsix9929]

Why don’t we have 100% lifter failures in these engines?

I had a 2009 Silverado 5.3 and now a new body 2019 5.3. Both trucks have never had a lifter issue.

I change the oil every 3-4 thousand miles and it's got 53 thousand miles on the engine, so far so good.

[@ohaggdah]

Great video Alex! It might be worth mentioning that almost every modern engine adapts this technology, even though many don’t advertise it. Whether its VVT/VVL/AFM/DOD.. they all cause similar issues and adapt a similar technology. And most modern engines have a combination of all. Even the 4 cylinders have it.. they can run on just 1. The Chrysler engines have probably the worst reputation in the industry, with the notorious “Hemi tick”. Also the 3.6 Chrysler Pentastar has a failure rate even higher than the GM V8’s if I’m not mistaken. Keeps mechanics busy… many wipe out cams below 50k… Sad times, but let me tell you, this technology won’t go anywhere. I just wish they could do it in a better way. Ford also just implemented cylinder deactivation in their 5.0… so let’s see how that goes. All you can do is be rigorous with your oil changes, and as soon as the warranty is over, get that stuff taken away. Although the whole point of the modern vehicle is that they shouldn’t be owned outside the warranty period… sad but true.

[@GettysGarage]

Agreed, it seems like this is just apart of the industry these days. I suspect ford may run into a similar issue but so far they seem to be holding up. and yes these engines are now all made to sneak out of the warranty period before they start to show any major issues.

[@jimsix9929]

one thing I see about all the new engines having lifter and cam failures is 30 years ago they took zinc out of the oil, that was there to protect the flat tappet cams of the day but would coat the catalytic converter ( that we no longer need), in the 1980s and 1990s the cam profiles were very tame, now people want power, a solution would be to ditch the useless converter and put zinc back in the oil, but if you have a 5.7 hemi or 3.6 as long as it is not burning oil, you can use valvoline VR1 racing oil, your camshaft will be happy, it has the zinc to protect the cam

[@newapocalypse09]

Had a 2019 with a collapsed lifter. Still under warranty. Took it to the dealer, they replaced only 1 bank and didnt touch the camshaft or anything else. I traded it in right away after the repair. 3k miles later, according to the carfax, the truck was back in the shop and had the lifters and campshaft replaced. They cheap out on the repairs even if the own techs recommend to repair it correctly. GM just wont pay for it, as you said, they just want it out the door to get it out of warranty. I also had a 2011 with a 5.3, night and day different. 157k miles and no worries. Should have never "traded up".

[@matthewanderson9912]

Some of your information is wrong in this video. I’m not defending GM but the 2021 model year is by far and away the most problematic for lifter failures. There was a TSB for trucks built between September 2020-March 2021 stating they potentially had bad lifters installed. GM says they had a bad run of lifters during this timeframe. Initially yes, they only replaced what was failed, so if #7 had the failure then you got two lifters for cylinder number 7 and that was it. However when the updated TSB came out they modified it to say if you were under 8,000 miles you got both banks of lifters replaced (so 16) and if you were over 8,000 miles you got the side that had the failure replaced. The cam would be inspected and replaced as needed. So I had a 2021 truck built in November of 2020 and I had a failure at 8,400 miles. Of course I only got the one side (#7 was the failure), didn’t need a cam they said and got 2 pushrods. Now maybe they have went back to only replacing what failed but I know the failure rate for 2019, 2020, 2022-up doesn’t seem nowhere near as bad as the 2021s. When the 2021s were new on the lots in the truck specific Facebook groups there was atleast one post a day about a lifter failure. And while there’s still failures with the other model trucks it’s nowhere near as frequent as the 2021s were. I think for those particular build date ranges it truly was bad parts. I’d say for a good majority of the rest it’s long oil change intervals. Just my 2 cents worth. I no longer have the 2021 truck for what it’s worth.

[@GettysGarage]

I appreciate the info! I'm not a GM tech myself so I could very well have gotten the TSB incorrect or miss-interpreted it. but regardless that's kind of tough they only gave you the one bank of lifters despite being only 400 miles over. I have heard the 2021 lifter were terrible and maybe it was a bad batch of lifters but I will 100% agree with you the very long oil change intervals is not helping at all. Why did you end up trading in the truck?

[@matthewanderson9912]

@@GettysGarage it’s possible they went back to their original handling of the issue with only replacing what failed but I do know for a fact with the 2021s they replaced at minimum the side that failed. Having the lifter failure basically is why I traded and I also wanted a 2500 truck when I got the 1500 but just couldn’t find one that would work for me. I was actually trading in a 2020 Duramax because of some problems it was having, (some emissions but ultimately I think it was a bad ECM-long story) and with the prices of trucks back then I couldn’t pass up the deal and the 1500 was all I could get. I realize mechanical failures happen but with GM knowing they had potential bad lifters during a specific date range and then me having a failure with a truck on that date range and being that close on mileage I just figured it was a matter of time before the other side had a failure. My truck is my daily driver and at the time it was our primary family vehicle and I was without it for 3.5 weeks waiting on parts and because their were two other 2021 trucks ahead of me at the dealer with the same problem (one was getting a cam also). So what time it was at the dealer they let me order a 2500 with no obligations to take it and no deposit required to place the order. That was October 9, 2021 and my 2022 2500 with the 6.6 gas came in December 14, 2021. I wanted the gas engine because of the diesel emissions problems that seem to be a “when not if” problem and the 6.6 L8T gas engine has no DFM technology. Couldn’t be happier with it. Just over 32,000 miles now and so far so good. Zero oil usage (I change oil at 3000 miles for what it’s worth) and it’s what I was truly wanting when I got the 2021 1500. As far as that goes it’s what I wanted when I got the 2020 Duramax but that’s another long story lol. Ordinarily I don’t trade trucks every year but again, a lot of check engine lights with the diesel and then the lifter failure with the 2021 5.3. Sorry about the long post but I really had sort of a whirlwind with trucks from August 2020-December 2021 lol.

[@TDub_ADV]

Tuning the AFM/DFM out via software is not a cure for this, not even a band aid. The lifters can and do still fail even on a tuned engine. I have personally experienced this myself on my 2018 where i tuned the AFM out before it even left the dealers parking lot. I let the truck sit for a week and a lifter bled down and when i started the truck it trashed the cam, bent a rod and busted a valve spring. This all happened within 10 seconds of starting it after sitting. Truck had like 12k on it or so at the time.

[@GettysGarage]

Yup agreed, It's not a cure but some people seem to think it can greatly decrease the likelihood of the lifter failures by not having them constantly actuated.

[@TDub_ADV]

@@GettysGarage I know of others that experienced similar to mine with AFM shut off by software or a range device. I don't think it decreases the chances of anything. This entire system is garbage, and its too bad because they have destroyed an otherwise fantastic engine platform. I have owned 3 of these engines, all 3 have failed, all 3 have failed early in the engines lifetime so its not a maintenance related issue, there has not been enough time for that to develop, heck one of them failed before it was due for its first oil change. The real killer for me. On one truck i installed a delete kit with a new cam, lifters, vlom block off etc as soon at my 3/36 was up. That truck got 1MPG better post delete than it did with the AFM system as it came from the factory. So all these failures for what? All they have done is make the vehicle less reliable.

[@chrissummers2689]

Something you can do without using a OBD tuner toggle is to shift into L or M and choose the 5 gear range on the 6-speed trans (gear range 7 for 8 speed trans). The AFM is never activated in this range and your fuel consumption is not really impacted. Unfortunately, you have to select the 5/7 gear range every time you shift into drive, but it becomes second nature (at least it did with me). It stinks we have to worry about a truck engine like this, but GM and all other auto manufacturers use engineered failure points to grab as much money as they can from the consumer.

Side note; my 2022 had the fuel management system deleted from factory w/ credit on invoice, so that tells me the valves are garbage no matter what.

Toyota was unwise not offering a V8 option for the latest Tundra. It could have lured customers fed up with major, persistent GM, Ford and Ram problems.

Happening to my 2017 right now. ugh! Thanks for the video.

GM did release a complete fix for the 5.3 and 6.2 lifter issues. It's called the 3.0 duramax.

You can’t replace a gas engine with a diesel without replacing the entire fuel and electronics.

[@rolandthethompsongunner64]

There are 💯 reliable engines. The 5.7 liter Toyota is rated most reliable V8 on earth. Pathetic when the Japanese can make better V8’s than Americans 😂

[@barrya.6212]

@@rolandthethompsongunner64 The 5.3 was the most reliable V8 until they ruined it with this lifter setup in 2007 ...and the Ford 5.0 is still bullet proof from what I've heard...in all it's iterations...

[@BrianDoherty-v3i]

well this happened to me on Friday. 2021 Trailboss 5.3 ... broken cam shaft, lifter and electrical issues with fuel mgmt system - daily driver to and from work - 55k miles... awesome...

[@pastorfred3460]

I have a 2015 Silverado with the 4.3 V6...have you found that the AFM on these are just as problematic for lifter failure as with the the 5.3 V8's? Thanks for these videos!

It's been pretty hard for decades now to even spot one with 2 headlights that work.

Are there any driving modes which keep the DFM system from deactivating any of the cylinders? I've heard in the Rams you can manually choose the highest gear "8" for driving and such results in the engine keeping all cylinders active.

[@jpowerhands3607]

Yes If you drive in manual speed five on the 5.3 generation's from 2015 to 2020 its stays in v8 mode the whole time which can be observed in the monitor while you driving This is how I drive my 2016 tahoe It might be the same for newer generations also It's worth a shot.
